说明：  建立包含直驱型风力发电机、单级式光伏发电系统和储能蓄电池的风能与光伏混合微电网模型。混合微电网在并网运行时，通过储能蓄电池平滑风能和光伏电源的输出功率波动，维持公共连接点电压。
(A wind power and photovoltaic hybrid microgrid model including direct drive wind turbine, single-stage photovoltaic power generation system and energy storage battery is established. When the hybrid microgrid is connected to the grid, it can maintain the voltage of the common connection point by fluctuating the output power of the energy storage battery smoothing wind energy and the photovoltaic power.)
