Optimal Scheduling of Integrated Energy Systems with User Comfort Consideration for Flexible Load Management

In recent years, in order to realize the goal of “double carbon”, the research and development of integrated energy system is very rapid, and the operation mode of the power grid is gradually changing from “source follows load” to “source-load interaction”. In order to strengthen the interaction between customer loads and grid loads, this paper proposes a flexible load optimization scheduling scheme that takes into account customer comfort. First, an integrated energy system model including photovoltaic, wind turbine, gas turbine, energy storage, etc. is established; second, an IES scheduling model with the optimization objective of cost minimization is established by considering the adjustable characteristics of demand-side flexible loads such as shiftable loads, transferable loads, and reducible loads, and considering the user comfort as an important constraint. The results of the study show that the program has obvious effectiveness in reducing the comprehensive operating cost by regulating the flexible load while satisfying the user comfort.
