In order to improve the absorption capacity of micro elements in microgrids and reduce the cost of traditional energy storage equipment, an equivalent energy storage device was designed, which was combined with traditional energy storage batteries and supercapacitors to form a three energy hybrid energy storage system. In order to respond reasonably to the power demand within the microgrid, a fuzzy control strategy based on traditional energy storage (state of charge) for three energy hybrid energy storage output power was proposed, and optimization research was also conducted on supercapacitors. Simulation shows that using the equivalent energy storage device and fuzzy controller designed in this paper is beneficial for achieving active power balance within the system and improving system frequency stability.
