Research on coordinated control and capacity allocation of multi-energy storage in DC micro-grid cluster
In order to improve the utilization of energy storage capacity in micro-grid cluster and reduce the economic cost of energy storage system, a multi-energy storage system of micro-grid cluster based on "centralized+decentralized" energy storage mode is proposed. According to the energy storage requirements of each subnet, the reasonable power limit for stabilizing fluctuations is selected. The "centralized+decentralized" multi-energy storage coordinated control strategy is adopted to achieve the stabilization of system power fluctuations, and the improved bat algorithm is used to obtain the optimal capacity configuration of "centralized+decentralized" multi-energy storage. Through simulation verification, the energy sharing among microgrid clusters is realized by the proposed "centralized+decentralized" multi-energy storage coordination control strategy and the optimal capacity configuration of "centralized+decentralized" multi-energy storage, the utilization rate of energy storage capacity is improved, and the economic cost of energy storage system in the network cluster is effectively reduced.
