Optimal Operation Strategy of Thermoelectric Microgrid Considering Demand Response

Thermoelectric microgrid is based on the traditional power microgrid, considering the electric heating conversion equipment and thermal demand, the formation of electric energy and thermal interaction complementary microgrid, electric heating coupling and conversion is of great significance to achieve the local consumption of new energy and achieve the goal of dual carbon. In this paper, new energy equipment such as cogeneration unit, energy storage, wind and light with micro-gas turbine and boiler as the main body are considered on the supply side. Multi-device coupling enhances the multi-energy supply capacity of the system. Secondly, two kinds of demand response models including load time shift and load reduction and operation scheduling constraints are constructed on the demand side. Finally, taking the minimum operating cost of the system as the objective function and the operation and demand response load regulation ability of various equipment as the constraints, the mathematical model of optimal operation of the microgrid based on the combined heat and power supply is established. The simulation results of a park show that the co-optimization considering cogeneration and demand response can effectively change the characteristics of the source and charge, and improve the flexibility and operation economy of the microgrid system.
