Title:
PHOTOVOLTAIC POWER GENERATION SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/041110
Kind Code:
A1
Abstract:
A photovoltaic power generation system and a control method therefor, used for implementing fast frequency support. The photovoltaic power generation system comprises: a direct current converter, adapted to be connected to an output of a photovoltaic module and performing voltage conversion on direct current outputted by the photovoltaic module; an inverter, used for converting direct current outputted by the direct current converter into alternating current and then outputting same to a power grid; and a first controller, used for generating a first driving signal according to two of a first voltage of the direct current of the direct current converter, active power outputted by the inverter, and an operating parameter of the power grid, and controlling the operating state of the inverter according to the first driving signal.
