Abstract
A power generation system includes a wind power generation device, a control device, and a power supply target. In power generation system, control device performs power conversion to a power generated by wind power generation device, and supplies the converted power to a power supply target. Control device has a reference map for controlling a power conversion device of the control device. Reference map is a map indicating a relationship between an input voltage to the control device (power conversion device) and an output power from the control device (power conversion device). When a start condition is satisfied, control device executes correction control for correcting reference map, and searches for a point at which an output power of power generation system is maximized while shifting the output voltage of a generator by MPPT control. Control device corrects reference map on the basis of a result of the search.
