Abstract

To create an operation plan capable of setting power to be provided to a power receiving device to a desired aspect and achieving a target requested by a power system.SOLUTION: An operation plan creation device 1 is applied to a power system consuming first power obtained from a first energy source (photovoltaic power generation device) and second power obtained from a second energy source (external system). The operation plan creation device comprises: a predicted value designation unit 11 designating a predicted value of power to be supplied as the first power from the first energy source to the power system; a constraint condition designation unit 12 designating a constraint condition which includes a term indicating the first power and a term indicating the second power, and separately treats the first power and the second power; a target function designation unit 13 for designating a target function formulating a target requested by the power system; and an optimization computation unit 15 obtaining an operation plan for the power system by solving a problem defined by the predicted value of the power to be supplied, the constraint condition and the target function.SELECTED DRAWING: Figure 2
