Optimal control of integrated energy system considering temperature comfort and carbon trade

Integrated energy system can realize multi-energy complementation and energy cascade utilization. The complex coupling relationship between the various devices has brought great challenges to the consumption of new energy and the suppression of source and load fluctuations. For such problems, this paper proposes a dispatching model based on comfortable temperature difference energy storage and reward-punishment tiered carbon trading mechanism. First, temperature comfort is used as a stimulus factor to construct a temperature difference energy storage model based on cold and heat demand response. Secondly, a comprehensive dispatching model of an integrated energy system to maximize economic benefits and minimize carbon emissions is established. This model improves user responsiveness while optimizing the output of supply-side equipment. In addition, the ability to complement multiple energy sources is significantly improved through a variety of high-energy conversion equipments. Finally, the effectiveness and feasibility of the model are verified by a numerical example using Gurobi solver.
