PROBLEM TO BE SOLVED: To provide a maximum power tracking control configuration which can be simplified and allows a reduction in time required to obtain the maximum power operation point.SOLUTION: In a maximum power tracking control configuration, an operation point of a power generation device is controlled by a power conversion device. A first voltage value V1 at an output end of the power generation device and a first current value I1 from the power generation device at a first time being one time are measured, and a second voltage value V2 at the output end of the power generation device and a second current value I2 from the power generation device at a second time being another time are measured, and the power conversion device is operated so that the voltage V and the current V of the power generation device become a voltage target value VXand a current target value IXbeing values obtained by formulae (1) VX=(V1-(V1-V2)/(I1-I2)×I1)/2 and (2) IX=(I1-(I1-I2)/(V1-V2)×V2)/2. |
