Title:
SYSTEM AND METHOD FOR CONTROLLING SOLAR POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/016006
Kind Code:
A1
Abstract:
The present invention is a technology for optimally controlling the voltage during a power suppression release. A system for controlling a solar power generation system has an inverter (21), a measurement unit (22), an MPPT + power control unit (23), an AVR (24), and a PWM (25). The MPPT + power control unit (23) has a function unit for MPPT for calculating an operating voltage command value of a PV array (1) on the basis of an operating voltage and output current value of the PV array (1) as measured by the measurement unit (22), and a function unit of for power control unit for control by a voltage command output by maximum power point tracking at all times from sunrise until sunset, inclusive even of when insolation is low.
