Research on Energy Storage Configuration and Optimal Scheduling of Cold-Heat-Electricity Coupled Integrated Energy System with Photothermal Power Station

In the study, an energy storage scheduling model of integrated energy system (IES) including thermal storage photothermal power station is constructed. Firstly, the photothermal power plant model is tuned, and the electric heater is introduced to recycle a single material that can be both solar energy and wind energy absorber. An optimization model for the thermal energy storage capacity of a photovoltaic power station is developed, considering the expenses associated with fuel, operation, and maintenance in a thermal power plant, as well as the storage costs of the photothermal power station's heat storage system. This model facilitates the optimization of the heat storage capacity, which is then incorporated into the subsequent Integrated Energy System (IES) model. Secondly, based on the optimal heat storage capacity obtained above, a multi-energy complementary integrated energy system model considering electric energy, heat energy and cold energy is established. Again, the scheduling model is established with the system operation cost and carbon emissions as the objective function. Last but not least, an example simulation confirms the established scheduling model's viability and efficacy.
