    • A control method for a wind turbine generator and storage battery unit connected to a power grid in parallel, includes calculating total active power and total reactive power, and switching between: a first mode in which the generator outputs turbine required active power and reactive power that can be outputted by the generator and the battery unit outputs battery required active power and battery required reactive power which correspond to a difference between the total active power and the turbine required active power and a difference between the total reactive power and the turbine required reactive power respectively; and a second mode in which the battery required active power is maintained and the battery required reactive power is reduced while the turbine reactive power is increased by an amount of the reduction of the battery required reactive power wherein apparent power exceeds a set battery unit apparent power.
    • 一种用于并联连接到电网的风力涡轮发电机和蓄电池单元的控制方法,包括计算总有功功率和总无功功率,并且在以下之间切换:第一模式,其中发电机输出涡轮机所需的有功功率和无功功率, 可以由发电机输出,并且电池单元输出对应于总有功功率和涡轮机所需有功功率之间的差异的电池所需的有功功率和电池所需的无功功率,以及总无功功率与涡轮机所需无功功率之间的差 分别; 以及第二模式,其中电池需要有功功率并且电池需要的无功功率降低,同时涡轮机无功功率增加电池所需无功功率的减少量,其中视在功率超过设定的电池单位视在功率 。
