Optimization Scheduling for Low-carbon Economy of Distributed Electric-Thermal-Gas Coupling Comprehensive Energy System

As energy systems continue to evolve and improve, the economic and environmental aspects of integrated energy systems have gained increasing attention. To enhance the overall utilization efficiency of social resources and achieve green low-carbon development in the energy industry, this paper proposes a low-carbon economic scheduling strategy for electric-thermal-gas coupling comprehensive energy systems. Firstly, an ”electricthermal-gas” energy conversion model is established, taking into account the influence of energy storage on the economic scheduling of the integrated energy system, as well as the transmission losses during energy transmission, to enhance energy efficiency. Secondly, in terms of environmental benefits, an improved tiered carbon trading mechanism is introduced for management. Then, by utilizing the leader-following consensus algorithm, the incremental cost of energy supply side is transformed into the incremental cost of electricity, heat, and energy storage of the system after energy hub, serving as the consistency variable, achieving distributed scheduling of the comprehensive energy system to achieve optimal output of energy supply units. Finally, the efficacy of the proposed low-carbon economy scheduling strategy is validated by different experimental cases.
