Reactive power compensation in solar power system

摘要

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).
