Optimizing of Integrated Energy Systems With CCHP-P2G on FTS Operation Strategy Using a Matrix Modeling Approach

Abstract

With carbon peaking and carbon neutrality goals, the integrated energy system (IES) is an effective way to achieve energy transition. To improve energy efficiency and reduce carbon dioxide emissions of the IES, a model of IES with CCHP-P2G and the FTS operation strategy is proposed. Firstly, a matrix modeling method is adopted in this model. This effectively improves the accuracy of system modeling. Meanwhile, a correction matrix is used to describe uncertain factors such as energy storage and renewable energy. Besides, this paper proposes the FTS operation strategy to avoid heating waste problems in traditional operation strategy, such as FEL and FTL. In the end, a method akin to a per-unit value is applied to structure evaluation criteria. The superiority of the proposed method is verified by the simulation results. The results demonstrate that the proposed model using CCHP-P2G and FTS operation strategy can improve the utilization of renewable energy, and reduce carbon emissions and thus achieve reductions in total operation costs and carbon emissions.
