摘　　要：分析了风光互补发电系统的技术优势,设计了基于固态变压器结构的并网型风光互补发电系统。分别建立了光伏系统,风力发电系统,超级电容和蓄电池的模型,并分析各环节的控制策略,提出了基于平均功率的储能设备容量配置方法。仿真结果表明,该系统能模拟风光互补系统在不同模式下的运行特性,可以有效降低功率波动和维持电压稳定,并能在低光照强度、低风速等情况下为系统提供短时能量支撑。This paper analyzes the advantages of the Wind/ PV Hybrid Generation System（WPHGS）, and designs the grid- connected wind/PV hybrid generation system based on the solid state transformer （SST）, and builds the simulation model for photovoltaic power and wind power generation system, super capacitor and battery respectively, and analyzes the control diagram of the system. The paper puts forward the capacity allocation method based on the average power for energy storage equipment. The simulation results show that the system can simulate the different operating characteristics of WPHGS, reduce the fluctuation of power and maintain the voltage stability effectively. It also can provide short-term energy support for the system and achieve reliable power supply under low irradiance, low wind speed and so on.
