Abstract: The use of regional comprehensive energy systems has the advantages of multi-energy complementation and coupling, and can comprehensively improve the optimal configuration of various energy consumption. This paper proposes a multi-objective low-carbon economic dispatch model for a regional integrated energy system, which fully exploits the advantages of heat storage devices, electric boilers and electric energy storage in the regional energy system to promote wind power grid-connected consumption. In addition, the influence of electricity price elasticity changes and temperature changes is taken into consideration, and a load elasticity demand response mechanism is established, which reduces the peak-to-valley difference of system load and further improves the online space of wind power. Finally, the NSGA-II algorithm under the improved elite strategy is used to optimize the scheduling model. The simulation results show that considerations of the peak-valley time-of-use electricity price and heat storage, energy storage and electric boiler installations can increase the space for further grid-connected wind power consumption, which is conducive to optimizing the low-carbon dispatch indicators in the regional comprehensive energy system. The IEEE-39 standard node power system and a 7-node thermal system are used to verify the rationality of the proposed model.
