In this paper, we analyze the average usage and priority of home appliances based on the characteristics of power data in household. In the case of electric power used in household, the control ability of individual appliance is determined according to the characteristics, and the analysis. Depending on the result of this kind of analysis, it is possible to suggest more efficient energy operation from the viewpoint of the energy consumer. Therefore, by analyzing the characteristics of each power source based on the time horizon, we set the priority of individual power resources according to the user preference. Through the application of this method, it is proposed to minimize the inconvenience of users' power operation and power operation fee. As a result, peak power was reduced by 15%, and the total power operation fee was reduced by 4%.
