Economic Operation Optimization of Electro-thermal Coupling System Considering Integrated Demand Response

Abstract

In this paper, an economic operation optimization model considering integrated demand response is proposed for electro-thermal coupling system. Firstly, based on the construction of the electro-thermal coupling system, according to the load response characteristics, and considering the vertical conversion and horizontal translation of energy, the loads are divided into curtailable, shiftable and replaceable loads, and an integrated demand response model is established. Secondly, taking the minimum sum of energy purchase cost, environmental cost and integrated demand response compensation cost as the objective function, and considering energy balance, energy conversion of equipment, energy storage equipment and IDR constraints, the system operation optimization model is established and the solution method is given. The simulation results show that the proposed model has good applicability to the economic operation of the electro-thermal coupling system. By fully exploiting the system's demand response capacity and exerting the multi-energy complementary and collaborative capacity, the economic operation capacity of the system can be further improved, and it has a good absorption capacity for clean energy. Also, it provides reference for economic operation of electro-thermal coupling system.
