    • A method of providing reactive power support is proposed. The method includes detecting at least one of a plurality of network parameters in a distributed solar power generation system (10). The generation system (10) includes a plurality of photovoltaic modules (12,26) coupled to a grid via inverters (14,16). The method further includes sensing a state of the photovoltaic modules (12,26) coupled to the distributed solar power generation system (10) and determining a reactive power measure based upon the sensed state and the detected network parameters. The reactive power measure is used to generate a reactive power command. The reactive power command is further used to compensate reactive power in the distributed solar power generation system (10).
    • 提出了提供无功功率支持的方法。 该方法包括检测分布式太阳能发电系统(10)中的多个网络参数中的至少一个。 发电系统(10)包括通过逆变器(14,16)耦合到电网的多个光伏模块(12,26)。 该方法还包括感测耦合到分布式太阳能发电系统(10)的光伏模块(12,26)的状态,并且基于检测到的状态和检测到的网络参数来确定无功功率测量。 无功功率测量用于产生无功功率指令。 无功功率指令还用于补偿分布式太阳能发电系统(10)中的无功功率。
