<p>In order to contribute to electricity supply and demand adjustment, consolidation of household responses is essential. A typical example of adjustment power is the preheating/precooling operation of air conditioners in houses. The operation model of an air conditioner requires an understanding of the insulation and heat storage characteristics of a housing. However, it is difficult to precisely model the detailed energy use of each household. In this study, we propose a framework to derive an optimal operation plan for residential air conditioner pre-heating and pre-cooling operation using a system identification method. The purpose of this study is to estimate the coordinating electricity for 500 households and to clarify the combination of the insulation and heat storage characteristics of the equipment and the housing, which contribute to the adjustment of power supply and demand, from the power saving plan selected by the aggregator. As a result, it was shown that the load estimation model of the residential air conditioner identified could derive a response to demand response while maintaining the comfort of level of residents. Also, the results of consolidation of 500 households showed that the pre-heating and pre-cooling of the air conditioner was selected secondarily after the heat pump water heater and that the higher the heat insulation performance, the lower the power saving and the lower the incentive price.</p>
