Description
Technical Field
The invention relates to the technical field of electric power, in particular to a method and a device for controlling demand response and an electric power control platform.
Background
The demand response is short for power demand response, and means that when the power price increases or the reliability of the power system is threatened, after a user receives a direct compensation notification of an inductive reduction load or a power price increase signal sent by a power supplier, the user changes the inherent conventional power consumption mode of the user to reduce or push a certain period of power consumption load to respond to power supply, so that the stability of a power grid is guaranteed, and the short-term behavior of power price increase is inhibited.
Currently, demand response is typically achieved by both interruptible load regulation and flexible load regulation by power consumers. In which load regulation can be interrupted and demand response is achieved mainly by forced switching off of the equipment. Although the load reduction amount of the demand response is large and the effect is obvious, the normal use is generally influenced by forcibly turning off the equipment. And the flexible load adjustment is realized by mainly adjusting the operation parameters of the equipment. Although this approach has less impact on the normal use of the equipment, the demand response load shedding amount is only 4% -10% of the interruptible load regulation, and the demand response duration is short.
In summary, in the prior art, when the demand response is realized, the load adjustment can be interrupted to affect the normal use of the user, the load reduction amount is small in the flexible load adjustment mode, and the demand response duration is short.

Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is in no way limited to any specific configuration and algorithm set forth below, but rather covers any modification, replacement or improvement of elements, components or algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present invention.
According to the control scheme of demand response provided by the embodiment of the invention, after the demand response instruction is received, the control command combination capable of continuously responding to the load reduction amount of the demand within the demand duration is determined from the pre-stored corresponding relation among the control command, the load reduction amount and the reduction duration, so that the load reduction amount and the load reduction duration can be ensured when the determined control command combination is used for controlling the equipment to run, and meanwhile, the influence on the normal use of a user during the demand response can be reduced through the matched use of one or more control commands in the control command combination.
It should be noted that the control scheme of demand response provided by the embodiment of the present invention can be applied in various technical fields of power supply to respond to demand response on the grid side or the microgrid side. For example, it can be applied to a refrigerator apparatus, a washing machine apparatus, a heating apparatus, and a cooling apparatus. The following embodiments of the present invention take a cold storage air conditioner in a cold supply device as an example, and detailed descriptions are provided for a control method, an apparatus and an electric power management and control platform for demand response provided by the embodiments of the present invention with reference to fig. 1-2.
Fig. 1 is a schematic flow chart of a method for controlling demand response according to an embodiment of the present invention. As shown in fig. 1, a method for controlling demand response according to an embodiment of the present invention includes:
step S101, a demand response instruction for starting demand response is received, and the demand response instruction comprises a demand load consumption amount and a demand duration.
In this step, receiving a demand response instruction for starting a demand response means that an electric power management and control platform receives a demand response instruction for starting a demand response, which is sent by an electric power supply side (a power grid or a microgrid), where the electric power management and control platform is used for managing and controlling electric power equipment at an electric power consumer side.
In practical applications, in order to facilitate the power consumer to respond to the demand response instruction, the power supply side generally sends a demand response notification instruction for representing the demand to the power management and control platform before sending a demand response instruction for initiating the demand response, where the demand response notification instruction includes a start time of the demand response, a load consumption amount of the demand, and a demand duration. The electric power management and control platform determines the load reduction amount and the duration which can be responded in the time period required by the electric power supply side according to the running state and the running rule of the equipment controlled by the electric power management and control platform, and feeds back the load reduction amount and the duration which can be responded in the time period required by the electric power supply side to the electric power supply side.
And after receiving the load consumption amount and the duration which can be responded by the power management and control platform in the required time period, the power supply side sends a demand response instruction for starting demand response to the power management and control platform in the required time period.
Step S102, determining a control command combination meeting a preset condition according to the load reduction amount and the demand duration of the demand and the corresponding relation among the control command, the load reduction amount and the reduction duration which are stored in advance, wherein the preset condition is the load reduction amount which continuously responds to the demand in the demand duration, and the control command combination comprises one or more control commands.
In this step, the power management and control platform may determine in advance one or more control commands for responding to the power supply side demand response, where the control commands may include a control command for interruptible load regulation and a control command for flexible load regulation. After the electric power management and control platform determines the control command, the electric power management and control platform can simulate and calculate the load reduction amount and the load duration of each control command, establish a corresponding relation among the control command, the load reduction amount and the reduction duration based on the calculation result, and store the corresponding relation in advance.
In specific implementation, after the power management and control platform receives a demand response instruction for starting demand response, the power management and control platform acquires the load reduction amount and the demand duration of the demand from the demand response instruction, and determines a control command combination meeting a preset condition, namely determines a control command combination capable of continuously responding to the load reduction amount of the demand within the demand duration, according to the load reduction amount and the demand duration of the demand and the corresponding relationship among the prestored control command, the load reduction amount and the reduction duration.
In specific implementation, a control command combination meeting a preset condition is determined according to the required load reduction amount and the required duration and the corresponding relation among the control command, the load reduction amount and the reduction duration which are stored in advance, and the method comprises the following two implementation modes.
In the first embodiment, if it is determined that the load reduction amount and the reduction duration corresponding to a single control command satisfy the preset condition, the control command is taken as a control command combination.
In the second embodiment, if it is determined that the sum of the load reduction amounts corresponding to the plurality of control commands is greater than the required load reduction amount and the reduction durations corresponding to the plurality of control commands are all greater than the required duration, the plurality of control commands are combined as one control command.
It should be noted that, according to the first and second embodiments, when determining a control command combination satisfying a preset condition according to the required load reduction amount and the required duration, and the corresponding relationship among the control command, the load reduction amount, and the reduction duration stored in advance, one control command combination may be determined, or a plurality of control command combinations may be determined.
Step S103, controlling the operation of the equipment based on the control command in the control command combination.
In this step, since one control command combination may be determined in step S102, a plurality of control command combinations may also be determined. Therefore, when the operation of the device is controlled based on the control commands in the control command combinations, if only one control command combination is determined in step S102, the operation of the device is controlled based on the control command combination; if a plurality of control command combinations are determined in step S102, before controlling the operation of the device based on the control commands in the control command combinations, a target control command combination for controlling the operation of the device needs to be selected from the plurality of control command combinations determined in step S102 according to a preset selection policy.
In one embodiment, the preset selection policy may be to select, as the target control command combination, a control command combination including a control command combination with the least number of control commands, or may select, as the target control command combination, a control command combination including a control command combination with the most number of control commands.
In an embodiment, when a target control command combination for controlling the operation of the device is selected from the plurality of control command combinations determined in step S102, the target control command combination may be selected in combination with the influence of each control command in the control command combinations on the user.
For example, if two control command combinations, denoted as control command combination 1 and control command combination 2, are determined in step S102, if one or more control commands included in control command combination 1 have a large influence on normal use of the device by the user when in use, and one or more control commands included in control command combination 2 have a small influence on normal use of the device by the user when in use, then when selecting the target control command combination for controlling the operation of the device, control command combination 2 is selected as the target control command combination.
The following describes the control method of demand response provided by the embodiment of the present invention in detail with reference to specific embodiments, taking a cold storage air conditioning device as an example.
When the device is a cold storage air conditioning device, the control command responding to the demand response instruction may include, but is not limited to: the method has the advantages of improving the set temperature of the outlet water of the heat pump, reducing the frequency conversion of the circulating pump, closing the air conditioning equipment in groups, increasing the cooling capacity, reducing the frequency conversion of the cooling pump, closing the heat pump and the geothermal circulating pump, reducing the opening degree of the fresh air valve, closing the fan coil and reducing the frequency conversion of the fan.
Specifically, when the cold storage air conditioning equipment is in a state of independent operation of the heat pump, if the load reduction required in the demand response instruction is in a Kilowatt (KW) level and the demand duration is in a minute level, the cold storage air conditioning equipment can respond by increasing the set value of the outlet water temperature of the refrigerating unit such as the heat pump, which is generally between 7 degrees centigrade (deg.c) and 10 deg.c, so that the set value of the outlet water temperature of the refrigerating unit such as the heat pump can be increased within a range of 7 deg.c to 10 deg.c. The response can also be made by reducing the circulating pump frequency conversion, i.e. the operating frequency of the water pump, which is typically in the range of 35 Hertz (HZ) to 50HZ, so that the circulating pump frequency conversion can be reduced in the range of 30HZ to 50 HZ.
When a control command for increasing the set value of the outlet water temperature of the refrigerating unit such as a heat pump and reducing the frequency conversion of the circulating pump is used to respond to a demand response command sent from the power supply side, the influence on the cooling experience of the user is small when the duration is short.
When the demand response instruction requires a large load reduction amount (for example, more than 100KW), and the demand duration is of an hour level, the refrigeration and heat supply units such as a group of heat pumps and the like and the corresponding auxiliary devices such as circulating pumps and the like can be turned off, and the cooling pump group is started, and at this time, the cold storage air conditioning device is in a state where the cooling pump group and the refrigeration and heat supply units such as other heat pumps run in a combined manner.
When the cold accumulation air conditioning equipment is in a state that the cooling pump set and other refrigeration and heat supply units such as heat pumps run in a combined mode, the quantity and the frequency of the cooling pump sets can be adjusted, and therefore cooling flow and cooling capacity can be adjusted. In addition, the number and the frequency of the cooling pump stations are increased, the cooling capacity and the load ratio of the cooling pump set can be increased, and therefore load reduction is achieved. When the required load reduction is further increased, the stopped refrigeration and heat supply units such as a heat pump and the like and the corresponding auxiliary equipment such as a circulating pump and the like can be added, and the cold accumulation and the cold release capacity are increased until all the refrigeration and heat supply units and the corresponding auxiliary equipment such as the circulating pump and the like are completely stopped, and the cold release pump set bears all the loads.
When the cold accumulation air-conditioning equipment is used for responding a demand response instruction sent by the power supply side, the type selection of the plate heat exchanger of the cold accumulation air-conditioning equipment needs to be selected according to the cold discharge capacity corresponding to the maximum value of the design demand response load reduction capacity. And the cooling pump set must select a variable frequency motor (5HZ-60HZ) to carry out large-range flow regulation and cooling capacity regulation, thereby increasing the adjustable range of demand response.
When the cold accumulation air conditioning equipment is in a state that the cold discharge pump set and other refrigeration and heat supply units such as heat pumps run in a combined mode, the adjustment of the load reduction amount of demand response is realized in a phase-changing mode through the change of the cold discharge amount, and compared with flexible load adjustment and interruptible load adjustment in the prior art, under the condition of multiple users, the load reduction amount of demand response can be responded in a multi-mode and permutation and combination mode under the condition that the user experience is not influenced and the cooling is guaranteed, so that the demand of the power supply side is met, and meanwhile, the flexibility of the system is enhanced.
When cold-storage air conditioning equipment is in the state of putting cold pump package independent operation, can also carry out further load through adjusting the frequency of putting cold pump package and subduct, nevertheless can lead to the cooling capacity not enough, influence user experience.
In order to guarantee user experience, a fresh air unit at the tail end of an air conditioner or an air conditioner unit containing a fresh air section can be adjusted to carry out demand response. For example, the fresh air valve is opened or closed to be turned down, and the cooling capacity is reduced, and meanwhile, the cooling demand in the building is reduced, so that the balance of the cooling demand and the supply is maintained, the temperature in the building is preferably ensured to be proper, and meanwhile, the fresh air corresponding to the fan can be subjected to frequency conversion adjustment or shut down. If the load reduction of demand response needs to be increased, a plurality of fan coils can be turned off.
Based on the same inventive concept, the embodiment of the invention also provides a control device for demand response. As shown in fig. 2, a demand response control apparatus according to an embodiment of the present invention includes:

And a control module 203 for controlling the operation of the device based on the control commands in the combination of control commands.
