Operation plan creating apparatus, operation plan creating method, and program

In one embodiment, an operation plan creating apparatus creating an operation plan for a generator which indicates operational state in a unit time. The apparatus includes a first, a 5 second and a third calculator, and an operation plan creator. The first calculator calculates a time frame constituted by a successive multiple unit times. The second calculator calculates multiple operation plan candidates for the generator in the time frame. The third calculator calculates coefficients associated with the 10 operation plan candidates on the basis of an initial solution of the operation plan of the generator in the time frame. The operation plan creator identifies one of the operation plan candidates in the time frame as the operation plan of the generator in the time frame by solving an optimization problem that uses the 15 coefficients at least either in an objective function or in a limitation condition.
