Multi-Objective Optimal Configuration of Integrated Energy System Considering the Load Transfer

Abstract

Demand response is an important means to optimize the load curve, reduce equipment capacity, and promote the consumption of renewable energy. This paper studies the multi-objective optimal configuration of the integrated electric and heat energy system considering the load transfer. Firstly, equipment models such as gas turbines, heat pumps, and batteries are proposed. Considering the demand response, the electric load transfer model and a price compensation mechanism are established. Secondly, the optimization model with economic, environmental protection, and dissatisfaction as the objectives is proposed, which can reflect comprehensive benefits. Then, the multi-objective problem is dealt with by stratified sequencing method, and the results of load optimization and equipment configuration are obtained by solving. Simulation results indicate that the proposed model and optimized scheduling method can balance multiple optimization objectives, reduce the gap between peak load and valley load, and are suitable for planning and operation scheduling of integrated energy systems.
