Research on Control Method of Hybrid Energy Storage System in Field of Distributed Generation

Abstract:

Super capacitor and batteries are designed based on the power converter. A control strategy of single zero-pole with variable gain is proposed in order to eliminate the affect of changes of super capacitor voltage on the system. It controls the discharge current of battery directly to let the current constant. Through the analysis the bode diagram of Open-loop system, stability and dynamic performance of the control system was demonstrate. Simulation result shows that the parallel control system can effectively optimize the battery discharge process and achieve complementary of the advantages two energy storage components.
