Fuzzy control method of electrochemical energy storage system based on source-load interaction

In order to improve the absorption capacity for large-scale new energy, a fuzzy control method for electrochemical energy storage system based on source-charge interaction is presented in this paper. According to the principle of source-charge interaction control, the optimization model of source-charge interaction electrochemical energy storage system is established. The minimum difference of source-charge interaction power is as the objective function, and the grid constraints are considered comprehensively. Combined with the technology of power prediction, the fuzzy control principle is introduced into the energy storage control strategy to improve the dynamic regulation accuracy of the control system. The effective response to the power fluctuations of the power grid is realized. The effectiveness of the proposed method is validated by the optimization results on the regional power system of North China.
