Study on Optimization and Evaluation of Integrated Energy System Operation Considering Time Constraints

In the face of the gradual depletion of fossil energy sources and the increasing demand for energy by human beings, the Integrated Energy System (IES), which is centered on the electric power system, promotes the consumption of renewable energy sources and realizes the complementarity of different energy sources by coupling various energy sources, such as electricity, gas, and heat, etc. However, IES brings great flexibility to end-users through the coupling of multiple energy sources, and at the same time poses challenges to the reliable supply of energy. However, IES brings great flexibility to end-users through the coupling of various energy sources, and at the same time brings challenges to the reliable energy supply of the system. Therefore, in this paper, we firstly construct an operation optimization model of IES considering time constraints; then, we randomly sample the system states and calculate the corresponding reliability indexes of energy supply. Finally, the reliability and economy of the IES under different operation modes are evaluated through case analysis, so as to provide a theoretical analysis basis for the construction of the actual park.
