Optimal residential comprehensive load demand response for integrated energy management systems coupling electricity, gas and heating

In recent years, the residential demand response in House Energy Management Systems (HEMS) has concentrated on off-peak power consumption of house loads considering only the scheduling of electricity. However, the advancement of multi-energy system and the increasing pressure on the grid give rise to the necessity of multi-energy EMS model research. In this paper, household equipment is classified into electrical equipment, gas-supplied equipment and heating-supplied equipment. Considering the combination among them, an advanced model of HEMS Coupling Electricity, Gas and Heating (CEGH) at the residential building level, which can achieve the redistribution of energy, is proposed in this work. By the means of simulation, this model achieves the redistribution of multi-energy, and thus it is proved superior on shifting peak load for the grid and reducing daily energy cost bills for residents than original single electricity scheduling model.
