考虑氢能利用与需求响应的综合能源系统低碳优化调度.

Integrated Energy System (IES) is of great significance to improve energy efficiency and reduce carbon emissions. Here, a low-carbon optimal scheduling approach is proposed for IES, which considers hydrogen energy utilization and demand response. On the source side, an IES model centering on hydrogen energy utilization is built to optimize the equipment operation flexibility. While on the load side, a demand response model based on Logistic function is built to optimize the load curves thus assist in carbon reduction, which takes into account of the users' energy consumption characteristics. In addition, a tiered carbon trading mechanism is introduced into the optimization model to further explore the carbon reduction potential. Finally, the IES is optimized and scheduled to minimize its total daily operating cost, considering the system's expenditure on energy purchase, operation and maintenance, carbon trading and wind abandonment. Case study shows that the proposed scheduling approach not only achieves peak shaving and valley filling, but also reduces the total operating cost and carbon emission of IES, which verifies its low-carbon and economical characteristics.
