Economic Scheduling of Electric-Heat-Water Multi-Energy Coupling Systems Considering Electric Vehicles and Demand Response

In the context of the increasing installed capacity of combined water and power units (CWP), this paper pro-poses an economic scheduling method for the electricity-heat-water integrated energy system, considering the charging and discharging strategy of electric vehicles and the demand response management strategy. First, the basic structure of the electricity-heat-water integrated energy system is construct, and the coupling mechanism between the systems is analyze. Then, with the goal of minimizing the total fuel cost of power generation, heat generation, and seawater desalination during the scheduling process, the economic scheduling method considering the behavior of electric vehicles and demand response management strategy is established. Finally, a simulation example is used to verify the proposed method, and the results show that the proposed method is conducive to realizing the low carbon economy operation of the system.
