With the continuous development and progress of society, human beings' demand for energy continues to increase, and traditional fossil energy sources such as oil and coal are drying up. Integrated energy systems have become the first choice to solve the energy crisis and alleviate environmental pressures. At present, the system has a single user variety and concentrated energy use time, which has led to problems such as low energy efficiency and waste of capacity. The purpose of this article is to study the optimization of island integrated energy systems that take into account demand response. This paper first analyzes the dispatchability of the power load and thermal load demand response of the island integrated energy system, and introduces the power and heat load demand response. Based on this, an optimal dispatching model of island microgrid integrated energy system based on demand response is proposed. The experimental results show that the optimal scheduling model proposed in this paper can effectively improve energy utilization and reduce energy abandonment rate. Based on the data of an island, the experimental part of this paper designs the integrated energy system. Based on the analysis of the new energy utilization rate and new energy discard rate under the combined demand response of electricity, heat and electricity, it was obtained that the new energy utilization rate was 89.67% and the new energy scrap rate was 15 %.
