Optimization of Spatial and Temporal Distribution of Carbon Emissions in a Thermoelectric Coupled System Based on the Cooperative Control Strategy of Electric and Thermal Energy Storage

Aiming at the carbon emission optimization of the thermoelectric coupling system, this paper innovatively designs the electrothermal energy storage collaborative PRO-CIES system, which improves the flexibility of the system through energy storage technology and optimizes the wind energy absorption by using time translation characteristics. We need to combine carbon trading and system constraints to optimize low-carbon economic scheduling. The empirical results show that, compared with the carbon trading model only, the proposed scheme can reduce wind abandonment by 8.12% and carbon emission by 88.27 tons. Compared with the electric energy storage model, the wind curtailation is reduced by 7.04%, and the carbon emission is reduced by 159.3 tons. Although the cost is slightly increased, the wind energy utilization and emission reduction are remarkable, which strongly supports the sustainable development of the energy system.
