Optimal Dispatch of Integrated Energy System Considering Source-Load-Storage Interaction

Abstract

With the continuous development of the integrated energy system, the access of energy storage and the response of multiple types of loads have increased the complexity of the optimal dispatch of the integrated energy system. The integrated energy system needs to have the function of extracting and processing massive data. The integrated energy system can make full use of the self-regulating ability of multiple types of loads and energy storage, and consider the interaction of source-load-storage to obtain higher economic benefits. On the basis of the integrated energy system, establish an electric energy storage model; for a translatable load, establish a load demand response model. Establish a comprehensive energy system model considering electricity-gas-heat, take the total cost of the system as the objective function, consider energy balance constraints and equipment constraints, and use CPLEX solver to solve. The simulation results show that the economic efficiency of the integrated energy system is improved after considering energy storage and the demand response of multiple types of loads.
