Abstract In order to solve the problem of voltage fluctuations caused by the low inertia, multi-mode, load sensitivity and other issues while microgrid is in operation, this paper discussed the configuration optimization of storage system. Taken the state of charge into consideration, the DC bus voltage is suppressed according to the voltage fluctuation amplitude, and then a hierarchical coordinated control strategy is put forward for the bus voltage in DC microgrid. This paper mainly utilized the complementary characteristics of the hybrid energy storage and the advantages of the gas turbine to suppress the voltage fluctuations precisely by the expected design of 7 modes. The models of power terminal and relaxation terminal coordinated mechanism were established in each model, and the hardware circuit and software flow were given. Through PSCAD/EMTDC simulation system as well as new energy power generation and energy storage integrated experimental platform, it is shown that the proposed control strategy is reasonable and feasible, and can meet the needs of expected design.
