Research on Integrated Energy System Planning for Typical Scenarios Considering Demand Response

Regional integrated energy system (RIES) widely involves many types of energy coupling, such as electric energy, thermal energy, cold energy and so on, and faces many challenges in planning. Realizing the coor-dination and complementarity of supply and demand among various energy sources and taking into account the flexibility of demand is a problem that must be considered in the process of integrated energy planning. A regional integrated energy planning method considering demand response is proposed in this paper. First of all, the energy configuration and load demand of four typical application scenarios of integrated energy in in-dustrial park, school, hospital and port area are analyzed, and the equipment configuration scheme of typical scenario is given; secondly, the demand response models of electricity, heating and cooling loads guided by price are established respectively. Finally, based on the energy hub (EH) model, a integrated energy planning model aiming at minimizing the sum of equipment investment, operation cost and demand response com-pensation cost is established, and the linearization method is used to solve the model. Relevant examples show that the proposed method can effectively carry out the integrated energy system planning in typical scenarios and reduce the planning cost.
