摘　　要：为了保证光伏发电系统在孤岛运行模式下供电可靠性及稳定性,提高光伏发电系统混合储能的运行效率和工作寿命,针对交直流混合微网架构的电能路由器,提出一种基于模糊控制的混合储能均衡控制策略,在确保系统瞬时功率平衡的同时,避免混合储能单元因过度充放电对自身造成的损害。通过Matlab/Simulink搭建了相应的仿真模型,并在孤岛运行模式下进行仿真研究,仿真结果验证了混合储能控制策略的有效性。In order to ensure the reliability and stability of power supply in isolated operation mode of the photo- voltaic power generation system, and improve operational efficiency and service lifetime of the hybrid energy storage, aimed at the electric power router based on hybrid AC/DC framework, a equalization control strategy of hybrid energy storage unit based on fuzzy control theory is proposed. The control strategy can keep the balance of instantaneous power and avoid damage to the hybrid energy storage caused by excessive charging and discharging power. The corre- sponding simulation model is built on the Matlab/Simulink platform, and simulation of the presented system in islan- ded operation mode is carried out. The simulation results show the validity of the proposed control strategy of hybrid energy storage.
