PROBLEM TO BE SOLVED: To obtain an output control method for a power generation system capable of making voltage at a regulation point be equal to or lower than regulation voltage regardless of output power of a power generation facility.SOLUTION: An output control method for a power generation system for performing a reverse power flow to a power system by system interconnection includes: a step (S1) of setting impedance of wiring between the power generation system and a regulation point whose voltage value is required not to deviate from a predetermined range; steps (S2, S3) of acquiring output current of the power generation system and output voltage of the power generation system; a step (S5) of calculating a voltage value of the regulation point on the basis of the impedance, the output current, and the output voltage; and steps (S6, S7, S8) of controlling output of the power generation system on the basis of the calculated voltage value of the regulation point. 【課題】発電設備の出力電力に係わらず規制点の電圧を規制電圧以下とすることができる発電システムの出力制御方法を得ること。【解決手段】系統連系により電力系統に逆潮流する発電システムの出力制御方法であって、電圧値が定められた範囲から逸脱しないことが要求される規制点と前記発電システムとの間の配線のインピーダンスを設定するステップ（Ｓ１）と、発電システムの出力電流と発電システムの出力電圧とを取得するステップ（Ｓ２，Ｓ３）と、インピーダンスと出力電流と出力電圧とに基づいて規制点の電圧値を計算するステップ（Ｓ５）と、計算した規制点の電圧値に基づいて発電システムの出力を制御するステップ（Ｓ６，Ｓ７，Ｓ８）と、を含む。【選択図】図２
