POWER SUPPLY CONTROL DEVICE, POWER SUPPLY CONTROL PROGRAM, AND POWER CHARGE SETTING SYSTEM

PROBLEM TO BE SOLVED: To provide a power supply control device capable of promptly predicting departure timing from electric power consumption planned in advance on a demand side and to appropriately control demand suppression control on the demand side when mutually controlling an amount of electric power between an electric power supply side and the demand side equipped with electric power generation facility.SOLUTION: Before a start of one block (one day), a demand side declares electric power consumed in the block as planned electric power, executes subsequent power prediction by a prediction calculation process such as a neural network for every unit period (every 30 minutes), determines whether the predicted power deviates from an allowable range on the basis of a difference between the predicted power and the planned power, and executes charge and/or load suppression to the storage battery 48 as preprocessing to avoid deviation from the allowable range. That is, if there is a surplus, charging the storage battery 48 is executed. By suppressing load within a range that a consumer does not realize inconvenience, it realized that the power consumption shifts according to planned power.SELECTED DRAWING: Figure 3 【課題】電力供給側と発電設備を備えた需要側とで相互に電力量を制御する場合に、需要側において予め計画した電力消費からの逸脱時期を早期に予測し、需要側でのデマンド抑制制御の適正化を図る。【解決手段】１ブロック（１日）の開始前に、需要側が、当該ブロックで消費される電力を、計画電力として申告しておき、１単位期間（３０分単位）毎に、ニューラルネットワーク等の予測演算処理によって以後の電力予測を実行し、予測電力と計画電力との差分に基づいて、予測電力が許容範囲を逸脱するか否かを判定すると共に、事前処理として、蓄電池４８への充電及び／又は負荷抑制を実行することで、許容範囲の逸脱を回避するようにした。すなわち、余剰があれば、蓄電池４８の充電を実行し、需要者側が不便さ実感しない範囲で負荷抑制を実行することで、計画電力どおりに消費電力が推移することを実現した。【選択図】図３
