Research on Multi-objective Optimization of Integrated Energy System Considering Integrated Demand Response

This paper constructs a multi-objective optimization model for the economy, energy efficiency, and environmental protection of the park-level integrated energy system, which includes a combined cooling, heating and power system, heat storage, battery swapping station, electric vehicles, gas boilers, air conditioning, and photovoltaic and thermal. Take battery swapping station, electric vehicles, and air conditioning as the main body of integrated demand response implementation. Use exergy efficiency as an energy efficiency optimization indicator, and pollutant discharge treatment costs as an environmental protection evaluation indicator. The model established in this paper can be solved by Cplex. Finally, the calculation example analyzes the impact of different integrated demand response implementation scenarios on the system operation. The results show that the model can take into account the economy, energy efficiency and environmental protection of system operation, and the effect of peak shaving and valley filling is significant, which can provide a reference for operators.
