PROBLEM TO BE SOLVED: To provide an energy management system capable of reducing the output variation of a power apparatus, and a power demand plan optimization method.SOLUTION: An energy management system 20 includes a demand plan calculation unit for calculating a demand plan, by solving the optimization problem of an alternative objective function f' including an original objective function f that is an index of optimization and a convex function, and a smoothing term being added to the original objective function f, and having a value increasing as the time fluctuation of variables, related to the output from a controllable output apparatus or an external power system 2 increases.SELECTED DRAWING: Figure 1 |
