Title:
METHOD FOR CONTROLLING PHOTOVOLTAIC POWER GENERATION, AND PHOTOVOLTAIC POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/019992
Kind Code:
A1
Abstract:
A method for controlling a photovoltaic power generation system and a photovoltaic power generation system, for use in reducing the photovoltaic energy loss in the photovoltaic power generation system. The method comprises: a photovoltaic power generation system separately presets an upper limit value for each converter in the photovoltaic power generation system (401), the upper limit value being a maximum voltage value of an output voltage-to-ground of the corresponding converter, and the output voltage-to-ground being a voltage difference between a positive output end of the converter and a grounding point of the photovoltaic power generation system; and the photovoltaic power generation system limits an output voltage-to-ground of a target converter according to the upper limit value corresponding to the target converter (402), the target converter being any converter in the photovoltaic power generation system.
