Stability Control Strategy of Hybrid Energy Storage DC Microgrid Based on Double Closed Loop
In order to solve the problems of high randomness and high volatility of photovoltaic power generation system, a DC microgrid system of accumulator-supercapacitors and photovoltaic power generation is constructed by using the complementary characteristics of accumulator-supercapacitors to photovoltaic power generation system. On the basis of comparative analysis of control principles, a double closed-loop PI control strategy suitable for DC microgrid hybrid energy storage is proposed. A photovoltaic power generation system model combining supercapacitor and battery hybrid energy storage is built under Matlab /Simulink. The simulation results show that the microgrid with double closed-loop control has better transient response speed and stability.
