Research on Operation Optimization of Integrated Energy System

The increasingly severe energy-saving situation and the need for sustainable development have brought the construction of integrated energy systems to a new level. The integrated energy system integrates multiple energy systems such as power supply, heating supply, and cooling supply. It is an inevitable trend in the development of modern energy systems to fully utilize the energy-saving potential of integrated energy systems through multi-energy complementary coordination and optimization. In this paper, an integrated energy system optimization scheduling model including a combined cooling, heating and power unit(CCHP) is proposed, and the optimal operation strategy of the integrated energy system under multi-season load demand is studied. The research results show that the integrated energy system can meet the requirements of energy security, stability and efficient supply under different seasonal conditions, and can significantly reduce energy operation costs.
