図1は、本発明の実施の形態にかかる集中電圧制御システムの構成の一例を示す図である。図1において、電圧制御機器1は変圧器型の電圧制御機器であり、例えば変電所に設置された配電用変圧器としてのLRT(Load Ratio control Transformer:負荷時タップ切替器付変圧器)である。電圧制御機器1にはローカル電圧制御装置11が接続されており、ローカル電圧制御装置11は電圧制御機器1を制御する。ローカル電圧制御装置11は、電圧制御機器1と一体的にまたは併設することができる。ローカル電圧制御装置11は、電圧制御機器1の制御量を調整することにより、具体的にはタップ位置を調整することにより、電圧制御機器1を制御する。また、ローカル電圧制御装置11は、通信機能を有し、通信ネットワーク9に接続されている。
電圧余裕減少量=閾値−電圧余裕 電圧余裕 < 閾値 の場合
電圧余裕減少量=0 電圧余裕 >= 閾値 の場合
…(1)
閾値は、ステップS21で設定した値であり、例えば、適正電圧範囲の幅の20%程度に定める。
評価関数値
= 配電系統各点の電圧上下限違反量の総和 × Wp
+ 変圧器ごとの電圧制御責任範囲内の各点の
上限側電圧余裕減少量の最大値 × W1
+ 変圧器ごとの電圧制御責任範囲内の各点の
下限側電圧余裕減少量の最大値 × W1
+ 前回指令時からの変圧器目標電圧変更量 × W2
+ 送電ロス × W3 …(2)
