Using a regional integrated energy system with the advantages of multi-energy complementarity and coupling, it can comprehensively enhance the optimal allocation of multiple energy consumption. This paper proposes a multi-objective low-carbon optimal dispatch model for a regional integrated energy system , which fully exploits the advantages of heat storage devices, electric boilers and electric energy storage in regional energy systems to promote the grid-connected consumption of wind power. By establishing a load elastic demand response mechanism, the peak-to-valley difference level of system load is reduced to further enhance the grid access space of wind power. Finally, the proposed scheduling model is optimally solved using the NSGA-II algorithm under the improved elite strategy.
