Research on Control Strategy of Hybrid Energy Storage System in Distributed Generation

Abstract

Abstract. A control strategy which is used in hybrid energy storage system is proposed in this paper. This control strategy has combined low pass filter with multi-objective optimization. Besides, the problems of overcharge, over discharge and limitation of maximum power are considered, which has improved the reliability of the system. The construction of the multi-objective optimization model and the coordination of the multiple protections are introduced in detail. And the advantages of the control strategy are validated by simulation in MATLAB.
