Description
まず、図1を参照して、本発明の一実施形態である保安工場選択のガイダンス装置の構成について説明する。
図2は、本発明の一実施形態であるガイダンス処理の流れを示すフローチャートである。図2に示すフローチャートは、入力部2を介してガイダンス処理の実行指令及び設定値が入力されたタイミングで開始となり、ガイダンス処理はステップS1の処理に進む。
本実施例では、外部からの電力供給が遮断されて停電が発生し、電力系統内の一部電源が脱落した場合において、自家発電量の範囲内において、工場の使用電力量が最大となるように稼働又は非稼働とする工場を選択する処理に本発明を適用した。なお、本実施例では、工場の電力使用量を正確に把握できる理想的な状況を想定して工場の電力値として実績値を用いた。そして、この前提のもと、(a)稼働・非稼働の工場選択の変更回数を抑制しない場合、(b)稼働・非稼働の工場選択の変更回数を抑制するが工場のグループ化を実施しない場合、及び(c)工場選択の変更回数を抑制して工場のグループ化を実施する場合の3つの場合に対して、整数計画問題を作成して稼働・非稼働の工場選択の組合せを算出した。
目的関数:MinimizeΣt{Σp自家発電量[t][p]-Σi工場選択[t][i]×工場電力量[t][i]}
決定変数:工場選択[t][i]∈{0,1}(0:非選択(非稼働)、1:選択(稼働))
制約条件:工場電力量[t][i]=実績値、目的関数≧0.1MWh
添え字: p:発電機名、i:工場名、t:時刻
停止継続(4時間):工場選択[t-1][i]-工場選択[t][i]≦1-工場選択[t+T2][i],T2∈{1,2,3}
・停電時に非稼働:工場選択[t][j]=0、j∈B=製鉄所の街灯等={その他}
・特定工場のグループ化:工場選択[t][k]=工場選択[t][l]、k,l∈C=事務所や子会社等={子会社A、子会社B、酸洗工場、中央事務所、分塊精整、シャフト炉}
