Energy management apparatus for customers

A customer-dedicated energy management apparatus, comprising:

• an air-conditioner partial-road characteristics identification unit for determining an approximation expression by using air-conditioner power consumption amounts collected by an air-conditioner state monitoring unit, air-conditioning operation achievement data, and intra/extra-room state achievement data,
• said approximation expression approximating power consumption amount in such a manner that a plurality of variables including air-conditioning output are selected as its explanatory variables,
• said air-conditioning operation achievement data being air-conditioner state values including said air-conditioning output,
• said intra/extra-room state achievement data being collected by an intra/extra-room state monitoring unit, and being intra/extra-room state values including room temperature;
• an intra-room heat-capacity characteristics identification unit for determining a relationship expression between an air-conditioning output change amount and a room-temperature change amount;
• an air-conditioning target power-amount calculation unit for calculating an air-conditioning power-amount target value;
• an air-conditioning setting temperature calculation unit for calculating
• an air-conditioning output adjustment amount from said air-conditioning power-amount target value calculated by said air-conditioning target power-amount calculation unit, and said approximation expression determined by said air-conditioner partial-road characteristics identification unit, said approximation expression approximating said power consumption amount such that said plurality of variables including said air-conditioning output are employed as said explanatory variables, and
• calculating
• an air-conditioning setting-temperature target value from said air-conditioning output adjustment amount calculated, and said relationship expression between said air-conditioning output change amount and said room-temperature change amount, said relationship expression being determined by said intra-room heat-capacity characteristics identification unit;
• and
• an air-conditioner control unit for controlling an air conditioner such that said air-conditioning setting-temperature target value calculated is selected as its instruction value.
