Abstract:
1. A photovoltaic (PV) power generation system, comprising: a plurality of PV collector units, each of the plurality of PV collector units comprising at least one PV cell and a collector-side single-phase inverter, the plurality of PV collector units each configured for coupling with an electrical grid via at least one transmission line; a grid-side inverter coupled between the at least one collector-side single-phase inverter of each PV collector unit and the electrical grid, the grid-side inverter configured to receive a single-phase alternating current (AC) output by each collector-side single-phase inverter and to provide a poly-phase AC to the electrical grid; and, a system controller communicatively coupled to each PV collector unit and to the grid-side inverter, the system controller configured to:
