Title:
PHOTOVOLTAIC GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/087946
Kind Code:
A1
Abstract:
A photovoltaic generation system (10) is provided with solar cells (2a-2c), inverters (3a-3c) provided corresponding to the respective solar cells (2a-2c), and a control device (1) for: determining whether or not the respective inverters (3a-3c) are in a power generation amount lowering state in which the corresponding solar cells (2a-2c) have power generation amounts lower than a predetermined criterion; generating a first command value for lowering a first power factor of the first inverter (3a) determined to be in the power generation amount lowering state; generating a second command value for increasing a second power factor of at least one second inverter (3b, 3c) determined not to be in the power generation amount lowering state so as to compensate the output power of the first inverter (3a) controlled on the basis of the first command value; and controlling the respective inverters (3a-3c) on the basis of the first command value and the second command value.
