Aggregation Method for Controllable Resources of Distributed Energy Storage in Distribution Areas Based on Edge Controllers

In order to realize low-cost aggregation of distributed energy storage adjustable resources in the substation and improve the coordinated and optimal control effect of different energy units, an aggregation method of distributed energy storage adjustable resources in the substation based on edge controller is proposed. According to the equivalent thermal parameter state equation, the actual output state equation and the electric vehicle state of charge equation, the mathematical model of resource aggregation is constructed. The objective function is constructed with the goal of minimizing the operation cost of resource aggregation in the substation, and the fuzzy PID controller is selected as the edge control logic. The objective function is solved by fuzzy rules of controller variables and triangular membership function, and the distributed energy storage adjustable resource aggregation in the substation is realized. The experimental results show that the operating cost of resource aggregation is about 20 yuan /h, and the F1 value is 0.964 and the G value is 0.956. It is proved that this method has good comprehensive performance.
