【 摘 要 】

PV-hybrid storage based DC microgrid is an effective large-scale application of PV generation. In this paper, the stability of the PV-hybrid storage based DC microgrid is analyzed based on the source-load impedance model and the stability rule is presented. Furthermore, the dynamic energy management strategy of PV-hybrid storage based DC microgrid is developed to both ensure the stable operation of the DC microgrid and realize the full utilization of the PV generation energy. A downscaled DC microgrid experimental prototype is developed and the detailed experimental results validate the correctness and feasibility of theoretical analysis and energy management strategy.
