It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The power distribution method provided by the application can be applied to a distribution system shown in fig. 1. The power distribution device 100 communicates with the renewable energy power generation system 200, the energy storage system 300, the gas production system 400, and the power grid system 500 via a network. The power distribution apparatus 100 determines that the energy storage system 300, the gas manufacturing system 400, or the power grid system 500 is a target power utilization system according to the power utilization mode input by the user, the renewable energy power generation system 200 uses the electric energy generated by the renewable energy source to perform at least one of energy storage, gas manufacturing, and power grid transmission, and if the electric energy generated by the renewable energy power generation system 200 cannot support the target power utilization system to operate, other power utilization systems may also perform auxiliary power supply on the target power supply system. The power distribution device may be implemented by an independent server or a server cluster composed of a plurality of servers, or may be implemented by a control chip integrated in the renewable energy power generation system.

Optionally, the energy storage system 300 includes a battery management unit and an energy storage battery, and the battery management unit is configured to receive an instruction from the power distribution apparatus to perform different operations according to different instructions, such as receiving electrical energy for storing electrical energy or releasing electrical energy.

Optionally, the gas production system 400 further includes a fuel cell, and the fuel cell converts chemical energy of the gas produced by the gas production system 400 into electric energy to be stored in the fuel cell, and the gas production system 400 can provide electric energy for other electric systems through the fuel cell.

Optionally, the renewable energy power generation system 200 is connected to the energy storage system 300, the gas production system 400, and the power grid system 500 through at least one power electronic converter, where the power electronic converter is configured to convert ac power generated by the renewable energy power generation system into dc power and output the dc power; the power electronic converter is also used for adjusting the voltage of the converted direct current to be more adaptive to a corresponding electric system.

In one embodiment, as shown in fig. 2, a power distribution method is provided, which is described by taking the power distribution apparatus in fig. 1 as an example, and includes the following steps:

step S201, determining a target power utilization system according to the power utilization mode input by the user, and indicating the target power utilization system to receive electric energy from the renewable energy power generation system.

The power utilization mode may be a mode preset manually, for example, the power utilization mode is as follows: the gas production mode, the power grid mode, the energy storage mode, the gas production mode + the power grid mode, the power grid mode + the energy storage mode and other designated modes can also be self-adaptive modes. The power consumption mode may be set according to the demand of the user, the power condition, and the like, which is not limited in this application. The target power system means a system for receiving electric energy generated by the renewable energy power generation system using renewable energy to support its operation, and may be one or more of a gas production system, a power grid system, and an energy storage system.

For example, the power consumption mode at this time input by the user to the power distribution device is an energy storage mode, and the power distribution device determines that the target power consumption system is the energy storage system according to a preset operation flow in the energy storage mode, and then the power distribution device sends an indication signal to the energy storage system to indicate the energy storage system to receive the electric energy generated by using the renewable energy from the renewable energy power generation system, so as to store the electric energy.

Step S202, determining auxiliary power supply information of the target power utilization system according to the power utilization requirement of the target power utilization system; the auxiliary power supply information comprises an auxiliary power supply system for auxiliary power supply of the target power utilization system and an auxiliary power supply strategy of the auxiliary power supply system.

The power consumption requirement can be changed according to different working states of the target power consumption system, for example, the electric energy required by the target power consumption system in the power consumption peak period is larger, and conversely, the electric energy required by the target power consumption system in the power consumption peak period is smaller. The auxiliary power supply system, i.e., the power system for assisting the target power system in operating, may be any one or more power systems other than the target power system, for example, when the gas production system is the target power system, the energy storage system and the power grid system may be the auxiliary power systems. The auxiliary power strategy may be indicative of how much power the auxiliary power system is capable of providing to the target powered system such that the auxiliary power system supports normal operation of the target powered system in conjunction with the renewable energy power generation system.

For example, after the target power utilization system is determined to be the gas production system, if the electric energy generated by the renewable energy power generation system cannot meet the minimum working electric energy required by the gas production system, the electric energy still required to be supplemented by the target power utilization system may be calculated by performing a difference operation or the like, and a system for assisting power supply of the gas production system, such as a power grid system and an auxiliary power supply strategy (electric energy output by the power grid system to the gas production system) is determined by combining the actual power utilization condition of the power grid system and/or the energy storage system. It should be noted that, in the case that the electric energy generated by the renewable energy power generation system can satisfy the normal operation of the target power utilization system, the power distribution apparatus does not need to determine an auxiliary power supply system for auxiliary power supply of the target power utilization system and a corresponding auxiliary power supply strategy.

And step S203, sending auxiliary power supply information to the auxiliary power supply system, and indicating the auxiliary power supply system to supply power to the target power utilization system according to the corresponding power supply strategy.

For example, based on the above-mentioned determination of the target power utilization system, the auxiliary power supply system for providing auxiliary power supply for the target power utilization system, and the auxiliary power supply policy corresponding to the auxiliary power supply system by the power distribution apparatus according to the corresponding information, the power distribution apparatus sends instruction information to the auxiliary power supply system to instruct the auxiliary power supply system to supply power to the target power utilization system according to the auxiliary power supply policy.

The application provides a power distribution method, which comprises the steps of determining a target power utilization system according to a power utilization mode input by a user, and indicating the target power utilization system to receive electric energy from a renewable energy power generation system to work after the target power utilization system is determined; when the electric energy provided by the renewable energy power generation system cannot meet the power demand of the target power utilization system, an auxiliary power supply system for assisting the power supply of the target power utilization system and an auxiliary power supply strategy of the auxiliary power supply system can be determined according to the power demand of the target power utilization system; and then, sending auxiliary power supply information to the auxiliary power supply system, and indicating the auxiliary power supply system to supply power to the target power utilization system according to the corresponding power supply strategy. The power distribution method provided by the application can dynamically allocate the electric energy generated by the renewable energy, the electric energy generated by the renewable energy can provide power for different power utilization systems, and is not limited to a single power utilization system, so that the electric power generated by the renewable energy is utilized to the maximum. In addition, different power systems can be used for assisting power supply as target power systems in different power utilization modes in a cooperative manner, so that the normal work of the power systems in different working modes is ensured, and the distribution of power is more reasonable.

In one embodiment, as shown in fig. 3, this embodiment is a possible method step of how to determine a target power utilization system, and the method step includes:

step S301, determining a target power utilization system according to a power utilization mode; when the power consumption mode is the self-adaptive mode, executing step S302; when the power consumption mode is the designated mode, step S303 is executed.

And S302, determining a target power utilization system according to the working condition of the renewable energy power generation system.

The power utilization mode may be a power utilization mode selected by a user on a preset interface according to time, a power generation working condition, requirements of a power utilization system and the like, and may also be a power utilization mode determined by the power distribution device according to time, a power generation working condition, requirements of the power utilization system and the like, for example: the power utilization mode can be as follows: a designated mode, a self-adaptive mode, an energy storage mode, a power grid mode, a gas production mode, a mode combining the energy storage mode and the power grid mode, and the like. The self-adaptive mode is used for distinguishing the designated mode, and indicates that the electric energy generated by the renewable energy power generation system does not designate a certain electric system, but determines a target electric system according to the working condition of the renewable energy power generation system, wherein the target electric system can be one or a plurality of electric systems. The working conditions of the renewable energy power generation system comprise severe working conditions and non-severe working conditions, the electric energy generated by the renewable energy power generation system under the severe working conditions is unstable and has severe fluctuation, the output power of the electric energy is represented in a large range or the output power of multiple sections is close to zero, and the non-severe working conditions are opposite to the severe working conditions. The working condition of the renewable energy power generation system can be judged by the power, the fluctuation frequency, the fluctuation amplitude and the like of the output electric energy. The target electricity utilization system is one or more of a power grid system, an energy storage system, and a gas production system.

For example, if the mode selected by the user on the preset interface is the self-adaptive mode, at this time, the power distribution device judges that the current working condition of the renewable energy power generation system is a bad working condition according to the information of the electric energy output by the renewable energy power generation system, the electric energy generated by the renewable energy power generation system under the bad working condition cannot be used for surfing the internet, that is, cannot be transmitted to the power grid system, and the electric energy generated by the renewable energy power generation system can be input into the gas manufacturing system for fuel manufacturing, so that the target power system at this time is the gas manufacturing system; the direct current component in the electric energy generated by the renewable energy power generation system can be input into a gas manufacturing system for gas manufacturing, and the high-frequency fluctuation component in the electric energy generated by the renewable energy power generation system is input into an energy storage system for energy storage, so that the target power utilization system is the gas manufacturing system and the energy storage system. The present application is not limited thereto.

According to the power distribution method provided by the embodiment of the application, under the condition that the power utilization mode is the self-adaptive mode, the target power utilization system is determined according to the working condition of the renewable energy power generation system, the target power utilization systems under different working conditions are different, so that the renewable energy power generation system can provide power for different power utilization systems by utilizing the electric energy generated by renewable energy, the power is not limited to a single power utilization system, the electric power generated by renewable energy is utilized to the maximum extent, and the resource waste caused by the fact that the electric energy generated by the renewable energy power generation system is distributed by a one-cut distribution mode is avoided.

And step S303, determining a target power utilization system according to the actual power utilization condition of the power utilization system corresponding to the specified mode.

For example, the specific mode represents a specific mode, such as a gas production mode, a power grid mode, an energy storage mode, a mode combining the power grid mode and the energy storage mode, a mode combining the gas production mode and the energy storage mode, and the like. For example: the specified mode is a gas manufacturing mode, if the electric energy generated by the renewable energy power generation system is surplus besides the normal work of the gas manufacturing system, the surplus electric energy can be transmitted to the energy storage system for energy storage, and the target power utilization system is the gas manufacturing system and the energy storage system; when the electric energy generated by the renewable energy power generation system only can meet the normal operation of the gas production system, the target power utilization system is only the gas production system. Therefore, it cannot be simply considered that the gas production system is the target power system in the gas production mode.

According to the power distribution method provided by the embodiment of the application, when the power utilization mode is the designated mode, the target power utilization system is further determined according to the actual power utilization condition of the power utilization system corresponding to the designated mode instead of directly determining the power utilization system corresponding to the designated mode as the target power utilization system, so that resource waste caused by the fact that the electric energy generated by the renewable energy power generation system is directly used for the power utilization system corresponding to the designated mode without considering the actual condition of the power utilization system is avoided. In addition, the situation that the electric energy generated by the renewable energy power generation system is directly used for the power utilization system corresponding to the specified mode under the condition that the electric energy generated by the renewable energy power generation system is not matched with the working electric energy required by the power utilization system can be avoided, the situation that the power utilization system cannot stably operate is caused, and the distribution of the electric power is more accurate and reasonable.

In one embodiment, as shown in fig. 4, the present embodiment is a possible implementation method for determining the operating condition of the renewable energy power generation system, and the method includes the following steps:

step S401, obtaining electric energy from the renewable energy power generation system, and determining fluctuation power, fluctuation amplitude and output power of the electric energy.

For example, in the self-adaptive mode, the power distribution device needs to obtain the electric energy of the renewable energy power generation system, analyze the electric energy to determine the fluctuation power, the fluctuation amplitude, and the output power of the electric energy, and then determine the operating condition of the renewable energy power generation system according to the fluctuation power, the fluctuation amplitude, and the output power of the electric energy. For example, the renewable energy source is light, the renewable energy source power generation system performs photovoltaic power generation, the working condition of the renewable energy source power generation system is a severe working condition in the photovoltaic power generation usually in four hours before and after twelve hours at noon, and the working condition of the renewable energy source power generation system in the rest of the time periods is a non-severe working condition, so that a user or the power distribution device can select different power utilization modes in different time periods, so as to better utilize the electric energy generated by the renewable energy source power generation system.

According to the power distribution method provided by the embodiment of the application, the working conditions of the renewable energy power generation system are determined through the data of the electric energy generated by the renewable energy power generation system in different dimensions in the power utilization mode which is a self-adaptive mode, so that the working conditions of the renewable energy power generation system are determined more accurately, the data of the electric energy in different dimensions are easily obtained, and the method is higher in implementability.

Step S402, determining the working condition of the renewable energy power generation system to be a non-severe working condition or a severe working condition according to the fluctuation power, the fluctuation amplitude and the output power of the electric energy.

For example, based on the analysis result of the power distribution device on the power generated by the renewable energy power generation system, the current working condition of the renewable energy power generation system is determined to be a severe working condition under the condition that the fluctuation frequency of the power of the renewable energy power generation system is greater than the first threshold, the fluctuation amplitude is greater than the second threshold, and the output power is less than the third threshold, otherwise, the current working condition is determined to be a non-severe working condition. For example, when the renewable energy power generation system generates power by using photovoltaic renewable energy, the first threshold value of the fluctuation frequency of the power generated by the renewable energy power generation system may be 5mHz (the average fluctuation period is less than 3min), the second threshold value of the fluctuation amplitude may be 0.04%/s (based on the rated power of the photovoltaic power generation system), and the third threshold value of the output power may be 30 kWh. It should be noted that the different types of renewable energy sources have different fluctuation powers, fluctuation amplitudes, and output power thresholds of the corresponding electric energy sources. The threshold value may be determined by the operating conditions of the gas production system at different electrical energies, which is not limited in this application.

According to the power distribution method provided by the embodiment of the application, the working conditions of the renewable energy power generation system are determined from different dimensions of electric energy, the working conditions of the renewable energy power generation system are determined more accurately, and reliable data support is provided for subsequently determining the target power utilization system.

In one embodiment, as shown in fig. 5, the present embodiment is a method for determining different target power utilization systems of a renewable energy power generation system under different operating conditions, and the method includes:

step S501, determining a target power utilization system according to the working condition of the renewable energy power generation system; executing step S502 under the condition that the working condition of the renewable energy power generation system is a severe working condition; if the operating condition of the renewable energy power generation system is a non-severe operating condition, step S503 is executed.

Step S502, determining that the gas manufacturing system is a target power utilization system.

For example, the renewable energy power generation system may not be on line due to poor quality of the generated electric energy under the severe working conditions, and the storage capacity of the energy storage system is limited, so the electric power distribution device may use the gas production system as the target power utilization system, and then instruct the gas production system to receive the electric energy from the renewable energy power generation system to supply the gas production system to produce the gas. The electric energy with low quality can be fully utilized, thereby avoiding the waste of resources.

And S503, determining the power grid system and the energy storage system as target power utilization systems.

Optionally, after the grid system and the energy storage system are determined as target power utilization systems, the method includes:

the grid system is instructed to receive a direct current component in the electrical energy from the renewable energy power generation system and the energy storage system receives a high frequency fluctuating component in the electrical energy from the renewable energy power generation system.

For example, when the operating condition of the renewable energy power generation system is a non-severe operating condition, the quality of the electric energy generated by the renewable energy power generation system is good, so that the grid connection is considered preferentially, that is, the renewable energy power generation system is applied to a power grid system, but the electric energy generated by the renewable energy power generation system has a stable direct current component and an unstable high-frequency fluctuation component, and only the stable direct current component can support the operation of the power grid system, and the energy storage system can store the unstable high-frequency fluctuation component. Therefore, after the power distribution device determines that the power grid system and the energy storage system are target power utilization systems, the power grid system is instructed to receive the direct-current component in the electric energy from the renewable energy power generation system, and the energy storage system receives the high-frequency fluctuation component in the electric energy. The distribution formula enables the electric energy input by the power utilization system of the renewable energy power generation system to be more adaptive to the electric energy required by the power utilization system, the distribution of the electric energy is more reasonable, the operation of the power utilization system can be better supported, and the distribution of the electric power is more reasonable.

In one embodiment, the present embodiment is a possible implementation method step of how to determine auxiliary power supply information of a gas production system when a target power utilization system is the gas production system, the step including:

and under the condition that the minimum value of the output power of the electric energy is smaller than the minimum working power of the gas manufacturing system, determining auxiliary power supply information of the gas manufacturing system according to the power consumption requirement of the gas manufacturing system.

For example, in the case that the power utilization mode is the self-adaptive mode, the power distribution apparatus determines that the gas production system is the target power utilization system according to the operating condition of the renewable energy power generation system, and then there is a case that: the minimum value of the output power of the electric energy generated by the renewable energy power generation system is less than the minimum working power of the gas production system. In this case, the gas production system will not work normally, so that other electric systems are needed to supply power to the gas production system to ensure the gas production system to work continuously and stably. The auxiliary power supply information of the gas manufacturing system is determined according to the power demand of the gas manufacturing system to assist the gas manufacturing system to normally work.

According to the power distribution method provided by the embodiment of the application, under the condition that the output power of the electric energy is smaller than the minimum working power of the gas manufacturing system, the auxiliary power supply information of the gas manufacturing system is determined according to the power demand of the gas manufacturing system so as to assist the gas manufacturing system to normally work, the stable operation condition of the gas manufacturing system is fully considered, and the long-term stable work of the gas manufacturing system is realized.

In one embodiment, as shown in fig. 6, the present embodiment is a possible implementation method for determining auxiliary power supply information of a gas manufacturing system, and the implementation method includes the following steps:

step S601, determining the difference power of the minimum value of the output power of the electric energy and the minimum working power of the gas manufacturing system, and determining one or more electric systems meeting the difference power as auxiliary power supply systems.

For example, if the minimum value of the power of the electric power output from the renewable energy power generation system is 10KW and the minimum operating power of the gas production system is 15KW, the gas production system cannot operate normally when the minimum value of the power of the electric power output from the renewable energy power generation system is reached. Under the condition, the electric power distribution device makes a difference between the minimum value of the output electric energy of the renewable energy power generation system and the minimum working power of the gas production system to obtain the difference power of 5KW, namely, the electric energy with the input power of more than or equal to 5KW is required to be input into the gas production system to meet the normal work of the gas production system. The electric energy can be obtained from a power grid system, an energy storage system, a part of the power grid system, another part of the energy storage system and the like, and then the power grid system, the energy storage system or the power grid system and the energy storage system can be determined as an auxiliary power supply system to provide electric energy matched with the differential power for the gas manufacturing system so as to provide continuous work for the gas manufacturing system.

According to the power distribution method provided by the embodiment of the application, when the output power of the electric energy generated by the renewable energy power generation system is at the minimum value and cannot meet the normal operation of the gas manufacturing system, the auxiliary power supply system of the gas manufacturing system is determined according to the difference power between the minimum value of the output power of the electric energy and the minimum operating power of the gas manufacturing system, the electric energy can be continuously provided for the gas manufacturing system during the operation period of the gas manufacturing system, the sudden stop of the gas manufacturing system caused by the fact that the output power of the electric energy generated by the renewable energy power generation system is at the minimum value and cannot meet the normal operation of the gas manufacturing system is avoided, finally the gas manufacturing system is in an intermittent operation state, damage is brought to the gas manufacturing system, and the service life of the gas manufacturing system can be prolonged.

Step S602, determining an auxiliary power supply strategy of the auxiliary power supply system according to the actual power consumption condition of the auxiliary power supply system and the differential power.

Illustratively, based on the above description, when the output power of the renewable energy power generation system reaches the minimum value, the input power of 5KW or more for the gas production system is required to satisfy the normal operation of the gas production system. Determining an auxiliary power supply strategy of the auxiliary power supply system according to the difference power of 5KW and the actual power consumption condition of the grid system and/or the energy storage system may be: the electric wire netting system is the electric energy that gas manufacturing system input and 5KW matchd, or energy storage system is the electric energy that gas manufacturing system input and 5KW matchd, or electric wire netting system is the electric energy that gas manufacturing system input and 2KW matchd and energy storage system is the electric energy that gas manufacturing system input and 3KW matchd etc. this application is not injectd to this.

According to the power distribution method provided by the embodiment of the application, the auxiliary power supply strategy of the auxiliary power supply system is determined according to the actual power utilization condition and the difference power of the auxiliary power supply system, so that the auxiliary power supply strategy is determined more reasonably, the purpose of continuously supplying power to the gas manufacturing system is achieved, and the effect of long-time stable work of the gas manufacturing system is achieved.

In one embodiment, as shown in fig. 7, this embodiment is a method step of determining a target power utilization system when the power utilization mode is the designated mode, and the method step includes:

step S701, determining a target power utilization system according to the actual power utilization condition of the power utilization system corresponding to the specified mode; if the designated mode is the power grid mode, executing step S702; if the designated mode is the gas production mode, step S703 is executed.

And step S702, determining a target power utilization system according to the power utilization load of the power grid system.

Illustratively, the power load of the power grid system includes a situation in which the power load is in a peak period and a situation in which the power load is in an off-peak period. When the power load of the power grid system is in different periods, the demand quantity of the power load is different, so that the power grid system cannot be simply considered as a target power utilization system in a power grid mode, the target power utilization system needs to be further determined according to the power load of the power grid system, the situation that the resource waste is caused because the actual power utilization condition of the power grid system is not considered, the electric energy generated by the renewable energy power generation system is directly and completely used for the power grid system is avoided, or the situation that the power grid system cannot stably run because the electric energy generated by the renewable energy power generation system is not matched with the working electric energy of the power grid system is avoided, and the distribution of the electric power is more accurate.

Step S703 determines that the gas production system is the target power consumption system.

For example, the gas production mode is different from the self-adaptive mode, in the gas production mode, the required amount of the gas is a certain value, and the required amount of the gas is not changed without ending the gas production mode, so that no form which is selectable to the power grid mode exists in the gas production mode, and the corresponding target power system in the gas production mode can only be a gas production system. The electrical energy produced by the renewable energy power generation system then needs to be used entirely to supply the gas production system. In addition, when the electric energy generated by the renewable energy power generation system cannot support the gas production system to produce a large amount of gas, the electric energy also needs to be taken from other electric systems to supply power for the gas production system in an auxiliary manner, so that the purpose that the gas production system can continuously produce a large amount of gas in a gas production mode is achieved.

In an embodiment, as shown in fig. 8, this embodiment is a possible implementation method for determining a target power utilization system according to power loads of a power grid system, and the method includes:

step S801, determining a target power utilization system according to the power utilization charge of the power grid system; when the power load of the power grid system is in a peak period, executing step S802; when the power load of the grid system is in a non-peak period, step S803 is executed.

And S802, determining the power grid system as a target power utilization system.

Illustratively, when the power load of the power grid system is in a peak period, the power demand of the power grid system is high, and the power grid system is determined as a target power utilization system, so that all electric energy generated by the renewable energy power generation system is input into the power grid system to be transmitted by the power grid system, and the normal work of the power grid system is ensured. In addition, if the electric energy generated by the renewable energy power generation system further includes a high-frequency fluctuation component, the energy storage system may receive the high-frequency fluctuation component in the electric energy generated by the renewable energy power generation system to store energy.

And step S803, determining the gas manufacturing system or the energy storage system as a target power utilization system.

For example, when the power load of the power grid system is in a non-peak period, it indicates that the power demand of the power grid system is small, and it is determined that the gas manufacturing system or the energy storage system is a target power system, so that the electric energy generated by the renewable energy power generation system may be completely input to the gas manufacturing system or the energy storage system, or may be partially input to the gas manufacturing system, or the other part is input to the energy storage system, or the like. In the power grid mode, when the power load of the power grid system is in a non-peak period, the gas manufacturing system or the energy storage system is determined to be the target power utilization system, so that resource waste caused by the fact that all electric energy generated by the renewable energy power generation system is input into the power grid system can be avoided, and the power distribution is more reasonable.

In one embodiment, the present embodiment is a possible implementation method for determining auxiliary power supply information of a target power utilization system according to a power demand of the target power utilization system, and the method includes:

and when the power load of the power grid system is in a peak period, determining auxiliary power supply information of the power grid system according to the power demand of the power grid system.

For example, when the power load of the power grid system is in a peak period, the electric energy generated by the renewable energy power generation system may not meet the normal operation of the power grid system, so that the auxiliary power supply information of the power grid system needs to be determined according to the power demand of the power grid system to supplement the shortage of the electric energy generated by the renewable energy power generation system, so as to provide stable electric energy required by continuous operation for the power grid system, and ensure that the power load of the power grid system can also continuously and stably operate in the peak period.

In an embodiment, as shown in fig. 9, this embodiment is a possible implementation method of how to determine auxiliary power supply information of a power grid system according to a power demand of the power grid system, where the method includes:

step S901, determining a difference power between the minimum output power of the electric energy and the working power of the grid system, and determining one or more power utilization systems meeting the difference power as an auxiliary power supply system.

For example, the power distribution apparatus determines the auxiliary power supply system by subtracting the output power of the electric energy and the operating power of the grid system to obtain a difference power. For example: the output power of the electric energy is 10KW, the working power of the power grid system is 20KW, namely, the normal work of the power grid system can be met only by the electric energy with the input power of the power grid system being more than or equal to 10 KW. The electric energy can be obtained from a gas manufacturing system, an energy storage system, a part of the gas manufacturing system, the other part of the energy storage system and the like, so that the gas manufacturing system, the energy storage system or the gas manufacturing system and the energy storage system can be determined as an auxiliary power supply system to provide electric energy matched with differential power for a power grid system, and continuous work of the power grid system is guaranteed.

According to the power distribution method provided by the embodiment of the application, when the output power of the electric energy generated by the renewable energy power generation system is at the minimum value and cannot meet the normal operation of the power grid system, the auxiliary power supply system of the power grid system is determined according to the difference power of the minimum value of the output power of the electric energy and the working power of the power grid system, the electric energy can be continuously provided for the power grid system during the operation period of the power grid system, the situation that the power grid system stops working suddenly when the output power of the electric energy generated by the renewable energy power generation system is at the minimum value and cannot meet the normal operation of the power grid system is avoided, the power grid system is finally in an intermittent working state, damage is brought to the power grid system, and the service life of the power grid system can be prolonged.

And step S902, determining an auxiliary power supply strategy of the auxiliary power supply system according to the actual power utilization condition and the difference power of the auxiliary power supply system.

For example, based on the above description, when the power of the output electric energy of the renewable energy power generation system reaches the minimum value, the electric energy with the input power of more than or equal to 10KW is also required for the power grid system to work normally. The auxiliary power supply strategy for determining the auxiliary power supply system according to the difference power of 10KW and the actual power consumption of the gas production system and/or the energy storage system may be: for the electric energy that electric wire netting system input and 10KW match in the gas manufacturing system, perhaps energy storage system is electric wire netting system input and the electric energy that 10KW match, perhaps gas manufacturing system is electric wire netting system input and the electric energy that 5KW match and energy storage system is electric wire netting system input and the electric energy that 5KW match etc. this application is not injectd to.

According to the power distribution method provided by the embodiment of the application, the auxiliary power supply strategy of the auxiliary power supply system is determined according to the actual power utilization condition and the difference power of the auxiliary power supply system, so that the auxiliary power supply strategy is determined more reasonably, the purpose of continuously supplying power to the power grid system is achieved, and the effect of long-time stable work of the power grid system is achieved.

and determining auxiliary power supply information of the gas manufacturing system according to the power load of the power grid system and the power demand of the gas manufacturing system.

For example, if the operating power of the gas production system is 30KW when the gas is produced in a large amount, the gas production system cannot operate in the corresponding operating mode when the power of the electric power output from the renewable energy power generation system is less than 30 KW. In this case, the power of the electric energy output by the renewable energy power generation system may be different from the working power required by the gas production system when a large amount of gas is produced, and the auxiliary power supply information of the gas production system may be determined according to the difference power, for example, 10KW and the electrical load of the power grid system: when the electric load is in a peak period, the power grid system and the energy storage system can be determined as auxiliary power supply systems of the gas manufacturing system, and the energy storage system can also be determined as an auxiliary power supply system of the gas manufacturing system. The auxiliary power supply strategy of the auxiliary power supply system is determined according to the difference power of 10KW and the actual power utilization conditions of the power grid system and the energy storage system, and comprises the following steps: the power grid system inputs electric energy matched with the output power of 5KW for the gas manufacturing system, and the energy storage system inputs electric energy matched with the output power of 5KW for the gas manufacturing system; or the power grid system inputs electric energy matched with the output power of 2KW for the gas manufacturing system, and the energy storage system inputs electric energy matched with the output power of 8KW for the gas manufacturing system; or, the energy storage system is an electric energy input by the gas production system and matched with the output power of 10KW, and the like, which is not limited in this application.

When the electric load is in a non-peak period, the power grid system and the energy storage system can be determined as auxiliary power supply systems of the gas manufacturing system, and the power grid system can also be determined as an auxiliary power supply system of the gas manufacturing system. The auxiliary power supply strategy of the auxiliary power supply system is determined according to the difference power of 10KW and the actual power utilization conditions of the power grid system and the energy storage system, and comprises the following steps: the power grid system inputs electric energy matched with the output power of 8KW for the gas manufacturing system, and the energy storage system inputs electric energy matched with the output power of 2KW for the gas manufacturing system; or the power grid system inputs electric energy matched with the output power of 9KW for the gas manufacturing system, and the energy storage system inputs electric energy matched with the output power of 1KW for the gas manufacturing system; or the power grid system is electric energy and the like which are input by the gas production system and matched with the output power of 10KW, and the like, which is not limited in the application

According to the power distribution method provided by the embodiment of the application, when the output power of the power generated by the renewable energy power generation system cannot meet the requirement that the gas manufacturing system can generate a large amount of gas, the auxiliary power supply system of the gas manufacturing system is determined according to the difference power between the output power of the power and the working power of the gas manufacturing system when the gas manufacturing system generates a large amount of gas, so that the auxiliary power supply system can continuously provide power for the gas manufacturing system during the period that the gas manufacturing system generates a large amount of gas, and the situation that the output power of the power generated by the renewable energy power generation system cannot meet the requirement that the gas manufacturing system generates a large amount of gas and cannot meet the production requirement is avoided.
