Research on Control Strategy of Hybrid Energy Storage System Based on Photovoltaic Power Generation

With the rapid development of new energy, photovoltaic power generation has received widespread attention. Photovoltaic power generation has randomness and intermittency and is usually combined with energy storage structures to maintain the balance of DC bus voltage and power. This article takes the photovoltaic DC microgrid with hybrid energy storage system as the research object, and studies its operation and control related issues. A hybrid energy storage system energy management scheme is proposed to address the drawbacks of short battery life and small supercapacitor capacity in hybrid energy storage systems; A coordinated control strategy for a photovoltaic DC microgrid with a hybrid energy storage system was studied for the rational utilization of various resources within the microgrid.
