| description | PROBLEM TO BE SOLVED: To provide an energy management system and a power demand plan optimization method capable of obtaining a solution reliably while shortening the time required for acquiring a solution.SOLUTION: An energy management system 20 includes a demand plan calculation unit 22c for obtaining the solution of a demand plan, including a control value for an apparatus at a plurality of times in a planning period, by solving the optimization problem of an objective function that is an index of optimization. The demand plan calculation unit 22c acquires a primary optimal solution S1 by searching a plurality of first discrete values obtained by dividing the value of independent variables, i.e., the variables of control value, while furthermore, acquires a secondary optimal solution S2 by searching a plurality of second discrete values obtained by dividing the value of independent variables in a range including the primary optimal solution S1 finer than the plurality of first discrete values.SELECTED DRAWING: Figure 1
【課題】解の取得に要する時間を短縮でき、しかも確実に解を得ることができるエネルギーマネジメントシステムおよび電力需給計画最適化方法を提供する。【解決手段】エネルギーマネジメントシステム２０は、最適化の指標である目的関数の最適化問題を解くことにより、計画期間内の複数の時刻における機器に対する制御値を含む需給計画の解を得る需給計画計算部２２ｃを備え、需給計画計算部２２ｃは、制御値の変数である独立変数の値を分割した複数の第１離散値を探索することにより１次最適解Ｓ１を取得し、さらに、１次最適解Ｓ１を含む一定範囲の独立変数の値を複数の第１離散値よりも細かく分割した複数の第２離散値を探索することにより２次最適解Ｓ２を取得する。【選択図】図１ |
