The Energy Management Strategies of Residential Integrated Energy System Considering Integrated Demand Response

In this paper, a novel residential integrated demand response model is proposed, which enables residential consumers to participate in demand response programs not only by shifting appliances, but also through changing energy types they consumed. The integrated demand response is modeled from three levels, namely the interactions with utility grids, the flexibilities of power, cooling and heating demands and the optimal operation of smart energy hub. In order to demonstrate the effectives and advantages of integrated demand response, four contrastive cases are studied, and simulation results show that the integrated demand response can bring better economic and environmental benefits. Furthermore, a new evaluation index: electricity substitute ratio is also proposed to evaluate the integrated demand response capacity and potential.
