Low-carbon economic dispatching model of electric-heating combined system considering multi-type energy storage

In order to reduce the wind abandonment rate during the winter heating period in the "Three North" region and the environmental pollution caused by carbon emissions during power generation, this paper proposes a low-carbon economic dispatching model that takes into account multiple types of energy storage for electric-heating combined systems. First, a multi-type energy storage model with electric boilers, electric energy storage, and heat storage as the core is proposed, and its internal energy conversion, storage, and output links are refined. Then, a carbon trading mechanism is introduced into electric heating. The combined system, taking into account the cost of carbon trading, and aiming at the lowest overall operating cost of the system, construct a low-carbon economic dispatching model for wind-power, conventional thermal power units, combined heat and power units, and multiple types of energy-storage combined heat and power systems. Yalmip/Gurobi solved the model and analysed the wind power consumption effect and carbon emission situation in the dispatching mode through numerical simulation. Simulation results show that under carbon trading, participation of multiple types of energy storage can effectively improve wind power utilization and the economic and environmental benefits of the system.
