Research on Low-Carbon Economic Dispatch of Integrated Energy System Based on Carbon Neutrality

Aiming at the optimization problem of integrated energy systems (IES) under the background of carbon neutrality, an optimal scheduling method considering the integrated energy environment and economy was proposed. Firstly, based on the concept of integrated energy, an integrated energy optimization model is established. Secondly, a staged carbon trading model and an optimal dispatching method are proposed. On this basis, with the goal of minimizing the economy of distribution network and environmental pollution, the low-carbon economic operation goal of minimizing the energy purchase cost, carbon emission cost and wind abandonment cost is further constructed. The original problem is transformed into a mixed integer linear problem, which is solved by Cplex and Yalmip solver. The effectiveness of the proposed strategy is verified by comparing and analyzing the scheduling results of different scenarios. The results show that the full use of multi-energy complementary integrated energy system can effectively reduce environmental pollution, and at the same time take into account the operation economy of the distribution network.
