“…On the other hand, it can promote clean and efficient use of traditional fossil fuels and support large-scale renewable energy development. [6][7][8] The traditional methods of producing hydrogen are basically separating H 2 from the by-product of fossil energy and industrial activities. However, these approaches are associated with high carbon emissions and environmental pollution.…”

“…In northern China, wind power during winter exhibits the characteristic of an anti-peak load with low generation and high generation at night (Zhao et al, 2021). Additionally, the "with heat to determine electricity" model restricts many combined heat and power (CHP) units (Liu et al, 2023), leading to significant wind curtailment. To improve wind power accommodation and reduce carbon emissions, heatstorage electric boilers, as a type of electric-to-heat conversion devices with time-shifting properties, have been widely studied.…”

The northern regions of China face the challenges of the mismatch of the power supply and demand, as well as serious wind curtailment issues, caused mainly by the limitation of the “with heat to determine electricity” mode for combined heat and power generation during the winter season. To further absorb the surplus wind power and alleviate restrictions, a comprehensive energy system optimization method for parks based on coordinated scheduling between sources and loads is proposed in this paper. First, the implementation of a heat-storage electric boiler on the source side further achieves the decoupling of heat and power. Second, an optimized scheduling method for electric vehicles combining incentive scheduling and orderly scheduling is proposed on the load side, which helps flatten the load curve. Finally, a tiered carbon trading mechanism is introduced and a community integrated energy system (CIES) optimization scheduling model is established with the aim of minimizing the total cost of the CIES, and the problem is solved using the CPLEX commercial solver. The simulation results indicate that the overall system efficiency is significantly improved through the coordinated scheduling of power sources and loads. Specifically, the integration rate of wind power increases by 3.91% when compared to the sole consideration of the integrated demand response. Furthermore, the peak shaving and off-peak filling effect is considerably enhanced compared to the utilization of only thermal-storage electric boilers. Additionally, the implementation of coordinated scheduling leads to a reduction in the total system cost by 2764.32 yuan and a decrease in total carbon emissions by 3515.4 kg. These findings provide compelling evidence that the coordinated scheduling of power sources and loads surpasses the limitations of thermal power units, strengthens the demand response capability of electric vehicles, and enhances the economic benefits of the CIES.
