Abstract

The integrated energy system in the industry park is an important material carrier for Chinese comprehensive energy demonstration projects. Its optimal scheduling often takes into account multiple goals with different dimensions and orders of magnitude. Under the background, based on the actual engineering construction of Tongli comprehensive energy service center, a multiobjective optimal scheduling model of integrated energy in the industry park with the goal of considering the overall energy efficiency of integrated energy, integrated energy costs, and collaborative consumption of renewable energy is established. At the same time, the solution set of the Pareto plane is obtained by using the fixed step length of the objective function after unitization. The ideal solution is selected by the near ideal solution sorting method after the Pareto plane is drawn by interpolation fitting. Finally, the Tongli Park is selected as a case to verify the above model. On the Pareto plane, a ideal solution is chosen as the optimal according to the actual engineering requirement. The operation of the various equipment in the industry park is analyzed to provide theoretical and technical support for the future construction and development of the integrated energy system in the industry park.
