Abstract: In the era of low-carbon energy transformation, the clean energy continues to develop in the large-scale and intensified direction. Aiming at the problem of the coordinated optimal scheduling of the CCHP microgrid including the multiple clean energy and the shared energy storage power stations, and considering the coupling characteristics of different types of loads and the incentive effects of the comprehensive demand response, a CCHP-SESS two-layer supply and demand coordination optimization model is built And a comprehensive satisfaction index for the electrical satisfaction, the thermal and the cooling comfort is proposed. In the two-layer model, the upper body is the cogeneration microgrid, and the lower body is the shared energy storage power station. The KKT condition is used for the dimensionality reduction, and the big M method is used to introduce the binary variables to linearize the nonlinear constraints. After converting to a mixed integer linear programming model, the CPLEX is called to solve it. Taking the CCHP-SESS system of a park in the Xinjiang Uyghur Autonomous Region as an example, the simulation analysis and verification results show that the comprehensive demand response is considered to effectively improve the load distribution and realize the efficient matching of the clean energy output characteristics and the load demand, relieving the pressure of energy supply. The proposed CCHP -SESS two-layer optimal configuration effectively reduces the operating costs of the CCHP microgrid by coordinating the energy distribution of different stakeholders at the upper and lower layers. Meanwhile, the revenue of shared energy storage power stations is increased, the level of clean energy consumption is improved, and the stability of system energy supply is ensured.
