Its worth in-depth research effectively integrating the potential of the user side response to the power grid using smart electricity demand response（DR）technology to improve its secure，stable and economical operation.Take the residential users for example，by using the capabilities of bi-directional interactive operation of the smart grid，a smart home appliances management（HAM）system with its control scheme is proposed.Models of different appliances are developed and according to their operating characteristics，an evaluation index is proposed that can represent the comfort of different appliances.To meet the requirements of DR and on the premise of the userscomfort，dynamic priorities of different appliances are calculated online according to their real-time status，and load control decision is performed in order of priority.The role in improving the power grid load curve is analyzed after the participation of all appliances in DR.The effects of the proposed HAM and its control scheme are analyzed for both the power company and the user.Simulation results have verified the rationality of the home appliance management scheme proposed.
