Abstract
A photovoltaic power generation system and a method for controlling power balance are provided. The system includes at least two photovoltaic arrays, at least one power balance circuit and a power converter. Each of input ports of the power balance circuit is connected with at least one photovoltaic array, and an output port of the power balance circuit is connected with the power converter. The power balance circuit performs power transfer based on a difference between output powers of the two photovoltaic arrays to control a difference between powers of two output terminals of the power balance circuit to be within a preset range.
