Wherein:

Detailed Description
So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
Example 1
Referring to fig. 1, for one embodiment of the present invention, there is provided a distribution method based on distributed control, including:
S1: collecting electric energy data of a power station; and metering power at an electric energy receiving end of the power distribution station by using a distributed device.
Further, the electrical energy data includes output voltage and current. By measuring the voltage and current, the output power of the power plant can be monitored in real time. This is critical to ensure stability and efficient management of the grid.
Still further, the distributed device is used as a node for edge calculation, is distributed at each receiving end and each distribution room, and can perform data analysis through a built-in algorithm; information sharing and power distribution control can be performed between other distributed devices. The metering of power at the receiving end of the power distribution station comprises calculating the power P received by the power distribution station from different power stations by means of the distributed device.
It is noted that by deploying distributed devices with data processing capabilities at the receiving end and distribution room, data can be processed instantaneously at the site where the data was generated. This reduces the need to send and receive large amounts of data to a central server, thereby reducing network load and speeding up response time. Information sharing and control decisions between distributed devices may stabilize the output of the system without causing imbalance in the electrical power output.
S2: the loss and the demand of power are calculated by the distributed device in the distribution room, feedback is carried out to the distributed device at the receiving end of the distribution station, and distribution control is carried out through the distributed device at the receiving end of the distribution station.
The power distribution room calculates the loss and the demand of power, wherein the power distribution room calculates the power loss rate V from the power distribution station to the power distribution room by using the output power P Into (I) of the power distribution station;
V=(P-P Into (I) )/P;
and counting the electricity consumption requirements of users responsible for each distribution room; learning the historical electricity demand by a distributed device at a distribution room results in a predictive function:
D(T+h)=σ(ωar·AR(p,T)+ωlstm·LSTM(X,T))·S(T)
Wherein AR (p, T) is the autoregressive model output; LSTM (X, T) is long-short-term memory network output; s (T) is a seasonal factor analysis result; p is the order of the autoregressive model and represents the hysteresis period number in the time sequence; x represents the feature set input to the LSTM; t represents the current point in time; h represents a predicted time interval, and the size of the predicted time interval is equal to the time delay of energy transmission plus the calculation time delay of a transformer substation; omega arlstm represents model parameters learned through a training process.
Qn=D(T+h)/V
The power supply demand power fed back by the nth power transformation chamber is represented by Q n.
It is noted that D (t+h) represents a prediction of power demand at a time in the future, which is calculated by an autoregressive model and a long-short term memory network based on historical data and current data. Accurate prediction of power demand is critical to ensure stable operation of the grid and to optimize power distribution. By calculation of V, the energy loss during the power transfer can be understood. This helps to more fully understand the efficiency of power transfer from the substation to the distribution room. By combining the predicted power demand D (t+h) with the power loss rate V, the calculated Q n can reflect the power that the utility actually needs to obtain from the utility after considering the transmission loss. And the power demand is monitored and predicted in real time, and the power grid can quickly respond to the demand change, especially in the peak or valley period of the demand by combining the analysis of the loss rate.
Further, the feeding back to the distributed devices at the receiving end of the distribution station includes feeding back the demand calculated by the distributed devices at each distribution room to all the distributed devices at the receiving end, and sharing the electric quantity received by the respective receiving end and the distributed electric quantity by each distributed device at the receiving end;
Total power of electrical demand:
the output control is performed by feeding back the obtained information and the calculation result thereof, and specifically comprises the following steps:
And predicting fluctuation of the received power of each distributed device by using a fluctuation prediction model FPM.
FPMi=LSTM(Ehistoryi)
Where E historyi is historical received power data for the ith device. The LSTM is a long-short-term memory network and is used for learning and predicting electric energy fluctuation, and the system can dynamically adjust the electric quantity output of each distributed device by integrating feedback information and historical data so as to meet the real-time requirement of the whole power grid. This helps to maintain the stability of the grid, especially in case of fluctuating or unpredictable demands.
And distributing the electric quantity output of each device according to the total electric quantity demand Z and the fluctuation prediction of each device.
TDMi=pos(Z,FPM1,FPM2,...,FPMW)
Where W represents the number of distributed devices at the receiving end. The optimization algorithm through the particle swarm is used for determining the electric quantity output of each device so as to meet the total requirement Z.
An optimal power output for each device is determined.
Wherein λ represents the adjusted intensity coefficient; the sign function represents determining an adjustment direction according to the difference value between the total demand and the current total output; j represents an index variable for traversing all distributed devices; k represents the residual adjustment quantity, which means the total maximum electric quantity sum which can be adjusted in the current adjustment step of the whole system on the premise of ensuring that the total output meets the total requirement Z; Δ i=TDMi-FPMi represents the output deviation of each device relative to its ripple prediction.
It is known that |Δ i |: this represents the absolute value of the output deviation of the ith device. The output deviation refers to the difference between the predicted output of each device and the actual demand calculated from the fluctuation prediction FPM i and the total demand distribution model TDM i. The absolute value is used to represent the magnitude of the deviation, irrespective of its positive and negative direction. Residual adjustment amount: this means the sum of the maximum amounts of power that the entire system can also adjust in the current adjustment step, with the total output being ensured to meet the total demand Z. This amount represents how much more power can be redistributed among the various devices while maintaining overall power balance.
The function of the expression min (|Δ i |, residual adjustment) is to select the smaller of these two values as the actual adjustment. The purpose of this is to avoid excessive adjustment of the individual devices, ensuring that the adjustment steps are smooth and gradually approach the total demand Z. The adjustment of the whole system is ensured not to exceed the residual adjustable electric quantity, and the overall balance of the power grid is maintained.
S3: and (3) rechecking the calculation and control of all the distributed devices through the central calculation of the power distribution station, and carrying out supplementary control according to the rechecking result.
Further, the rechecking of the calculation and control of all the distributed devices comprises that a central calculation unit of the power distribution station utilizes the learning of a neural network to plan a stable output interval for the predicted fluctuation of the received power of each distributed device; analyzing whether each distributed device is in a stable output interval; if the power demand is too large, the optimal power output of the distributed device is not in a stable output interval, the energy storage system is utilized to carry out power supplement, and in the process of the supplement, the power output data of each device is continuously updated until all the power outputs are in a planned stable output interval; and when the power is supplied, if the received power is larger than the output power, charging the energy storage system.
It is known that modern power systems typically collect and store a large amount of historical power data, including power generation, load demand, weather conditions, etc., which provides a rich data base for training of neural networks. Neural networks, particularly deep learning models such as Long Short Term Memory (LSTM), have demonstrated their powerful data processing and predictive capabilities in many areas. Neural networks are particularly suited for processing complex, nonlinear, time series data, which is characteristic of power system data. The neural network is good at identifying patterns and trends in the data, and can identify and predict stable intervals of power output by learning historical data. The neural network may analyze the pattern of fluctuations in the historical data to predict possible stable and unstable output intervals in the future.
It is also known that analyzing and predicting the power fluctuation of each device through the neural network can help the power system to more effectively plan the stable output interval of each device, thereby reducing the risk of grid instability caused by fluctuation. When the power demand is overlarge, the energy storage system is utilized to supplement power, so that the power grid can maintain stable operation when the demand is high, and meanwhile, the energy storage system is charged when the power supply is less, and the flexibility and the response capability of the power grid are improved. By continuously monitoring the power output of each device and making the necessary adjustments, it is ensured that the output of all devices remains always within a stable output interval, which is critical for reliable operation of the grid. The utilization of power resources can be optimized, the waste is reduced, and the energy efficiency of the system is improved by precisely controlling the output of each distributed device and the use of energy storage.
In another aspect, the present embodiment further provides a distributed control-based power distribution system, including:
and the information acquisition module is used for acquiring electric energy data of the power station. The distributed computing module is used for metering electric quantity at an electric energy receiving end of the power distribution station by utilizing a distributed device; and calculating the loss and the demand of the electric energy in the distribution room by using the distributed device, feeding back the electric energy to the distributed device at the receiving end of the distribution station, and performing distribution control on the electric energy through the distributed device at the receiving end of the distribution station. And the central control module is used for rechecking the calculation and control of all the distributed devices through the central calculation of the power distribution network and carrying out supplementary control according to the rechecking result.
