Abstract For the hybrid microgrid composed of multiple distributed generations, considering the coordinated control of photovoltaic and energy storage system in islanded mode, the energy management strategy is studied. Firstly, an improved dynamic droop control method considering SOC balancing is proposed, to enhance the power balancing between different energy storage systems and prolong the service life of the battery. Secondly, since the photovoltaic output power fluctuation and SOC states variation, a multi-mode switching control algorithm for distributed power supplies is designed. Depending on the scenarios, it operates in different control modes to achieve energy management objectives of the decentralized microgrid. By constructing the Matlab/Simulink model, the energy storage system can quickly allocate the power according to the SOC state, and coordinate the PV system to maintain the stable operation of the microgrid, thus verifying the feasibility and effectiveness of the proposed control strategy.

Key words： Microgrid distributed generations SOC balancing droop control coordinated control
