Title:
SOLAR PHOTOVOLTAIC POWER GENERATION SYSTEM AND SOLAR PHOTOVOLTAIC POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/058428
Kind Code:
A1
Abstract:
This solar photovoltaic power generation system is provided with a plurality of solar cell arrays, a plurality of power conditioners connected respectively to the plurality of solar cell arrays, and a higher-level device connected to the plurality of power conditioners. The higher-level device is constructed so as to execute, by overlapping chronologically, first output control in which output power output by a designated power conditioner is adjusted to a predetermined prescribed output power, and second control in which the output power of the remaining power conditioners is adjusted so that the equivalent of the change in the quantity of power generated by the designated power conditioner due to adjustment of the output power of the designated power conditioner to the prescribed output power is borne by the remaining power conditioners. The higher-level device is constructed so as to execute characteristic data acquisition, in which the input power electrical characteristics of the designated power conditioner during execution of the first output control are acquired.
