Voltage in a power transmission-distribution system is managed by calculating a power control amount of a distributed energy resource in consideration of the whole power transmission-distribution system. A power control system includes: a power distribution system contraction unit contracting the power distribution system including the distributed energy resource in a point of a power transmission system using control power amount range, and calculating a contraction control power amount range; a contraction power amount calculation unit calculating a contraction power amount to satisfy the contraction control power amount range based on a power transmission system evaluation value; a power control amount calculation unit calculating a power control amount controlled by the distributed energy resource based on the contraction power amount and a power distribution system evaluation value; and a communication unit transmitting the power control amount to the distributed energy resource.

Current information is information on a current time step for a power system including a reactive power supplier. A plurality of pieces of future information are a plurality of pieces of information on a plurality of future time steps for the power system. Power installation information is information on installations constituting the power system. An optimal power flow problem is formulated by an objective function and a plurality of constraint expressions based on the current information, the plurality of pieces of future information, and the power installation information. The control command is set based on a variable determined by the optimal power flow. In at least one of the objective function and the plurality of constraint expressions, amounts of variation of an input of the reactive power supplier at the current step and the plurality of future steps of the reactive power supplier are accumulated.
