摘要
为实现综合能源系统安全、灵活、低碳运行,提出一种计及低碳响应的源-荷互动优化调度策略,并在日前、日内等多时间尺度上进行研究。首先,基于综合能源系统的供能结构和多能互补关系,建立包含需求响应负荷和储能设备的混合能源集线器模型;其次,制定面向约时、实时响应负荷的需求响应策略,通过源、荷两侧共享调度信息,实现基于低碳响应的源-荷互动;引入碳排放均摊成本,以经济性、碳排放、用户舒适度为优化目标进行日前优化调度,并基于日前计划开展日内滚动和日内实时调度。仿真结果表明,该策略能充分挖掘源、荷两侧资源的调度潜力,缓解新能源消纳问题,为综合能源系统经济、低碳调度提供参考。
To realize the secure,flexible,and low-carbon operation of integrated energy system,an optimal scheduling strategy that considers the low-carbon demand response is proposed.This strategy considers the interaction between source and load sides and conducts research at multi-time scales,including day-ahead and intra-day.Firstly,a hybrid energy hub model is established based on the system structure and multi-energy complementary,incorporating elements of demand response load and energy storage.Then,a demand response strategy is devised for contracted and real-time response loads that possess varying response speeds,and within the system,scheduling information is communicated to attain a low-carbon demand response through interactive means.Finally,the dayahead optimal scheduling considering the shared cost of carbon emission is implemented,with the aim of achieving the lowest economic cost,the lowest carbon emission,and the highest user comfort.The day-ahead plan guides the performance of intra-day rolling and realtime optimal scheduling.The simulation results indicate that the proposed strategy can efficiently exploit the scheduling potential of both source and load resources,mitigate the accommodation issue of renewable energy,and furnish insights for the economic and low-carbon scheduling of integrated energy systems.
