Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a technology capable of optimumlly performing voltage control at the time of power suppression release.SOLUTION: A control system of a solar light power generation system includes an inverter 21, a measurement part 22, an MPPT+ power control part 23, an AVR 24, and a PWM 25. The MPPT+ power control part 23 includes an MPPT functional part which calculates an operation voltage command value of a PV array 1 based on an operation voltage and an output current value of the PV array 1 measured with the measurement part 22, and a power control part functional part for controlling with a voltage command output by maximum power point follow-up always from sunrise to sunset, including a case of low solar radiation. 【課題】電力抑制解除の際の電圧制御を最適に行う技術を提供する。【解決手段】太陽光発電システムの制御システムは、インバータ２１、計測部２２、ＭＰＰＴ＋電力制御部２３、ＡＶＲ２４、ＰＷＭ２５を有し、ＭＰＰＴ＋電力制御部２３は、計測部２２により計測されるＰＶアレイ１の動作電圧および出力電流値を基にＰＶアレイ１の動作電圧指令値を算出するＭＰＰＴの機能部と、日の出から日の入りまで、低日射の場合も含めて常に最大電力点追従による電圧指令出力により制御する電力制御部の機能部とを有する。【選択図】図１
