PROBLEM TO BE SOLVED: To provide a power conversion system, a power source system and a power management system capable of individually identifying a power value of power that a power system exchanges with each DC power source.SOLUTION: A power conversion system 1 comprises: a plurality of DC/DC conversion circuits 2; at least one DC/AC conversion circuit 3; a measurement part 4; and an arithmetic part 51. The plurality of DC/DC conversion circuits 2 are electrically connected to a plurality of DC power sources 6, and converts a size of an input DC voltage. The DC/AC conversion circuit 3 is electrically connected to the plurality of DC/DC conversion circuits 2 and a power system 8, and performs voltage conversion between the DC voltage and an AC voltage. The measurement part 4 measures at least either an input power or output power of each of the plurality of DC/DC conversion circuits 2. The arithmetic part 51 calculates an exchanged power value as a power value of power that the power system 8 exchanges with each of the plurality of DC power sources 6 on the basis of a measurement result of the measurement part 4.SELECTED DRAWING: Figure 1 【課題】電力系統が各直流電源との間で授受する電力の電力値を個別に識別可能な電力変換システム、電源システム、及び電力管理システムを提供する。【解決手段】電力変換システム１は、複数のＤＣ／ＤＣ変換回路２と、少なくとも１つのＤＣ／ＡＣ変換回路３と、計測部４と、演算部５１と、を備える。複数のＤＣ／ＤＣ変換回路２は、複数の直流電源６と電気的に接続され、入力された直流電圧の大きさを変換する。ＤＣ／ＡＣ変換回路３は、複数のＤＣ／ＤＣ変換回路２、及び電力系統８と電気的に接続され、直流電圧と交流電圧との間で電圧変換を行う。計測部４は、複数のＤＣ／ＤＣ変換回路２の各々の入力電力と出力電力との少なくとも一方を計測する。演算部５１は、電力系統８が複数の直流電源６の各々との間で授受する電力の電力値である授受電力値を、計測部４の計測結果に基づいて算出する。【選択図】図１
