为应对高比例新能源电力系统中因新能源出力不确定性导致的系统爬坡压力，提出了一种储能与需求侧资源协同参与的电能量-灵活爬坡产品（flexible ramping products，FRP）联合交易机制。构建了计及储能与需求侧资源参与的电能量-FRP市场优化调度模型，对FRP采用多段定价方式以激励系统中的可调节资源参与FRP服务，通过需求响应实现了储能和需求侧灵活资源协同为系统提供爬坡能力，满足了系统的爬坡需求。基于IEEE 30节点系统的仿真结果表明，在系统净负荷急剧增大的关键爬坡时段，储能参与FRP服务不仅可以有效减少上行灵活调节服务（flexible ramp-up，FRU）的出清频次，还显著降低了FRU的价格，特别是在新能源渗透率较高的场景中，储能的快速响应特性可以显著增强系统的灵活性和稳定性。此外，研究还发现储能参与FRP服务虽然在一定程度提高了能量市场价格，但整体上提升了系统的调节能力。

A joint trading mechanism for electricity energy and flexible ramping products （FRP） with the collaborative participation of energy storage systems （ESS） and demand-side resources （DSR） is proposed to address the system ramping pressure caused by the uncertainty of new energy output in power systems with a high proportion of new energy. An optimized dispatching model for the electricity energy-FRP market is constructed, considering the participation of energy storage and demand-side resources. A multi-segment pricing approach is adopted for FRP to incentivize adjustable resources in the system to participate in FRP services. Through demand response, energy storage and flexible demand-side resources collaborate to provide ramping capacity for the system, meeting the system's ramp requirements. Simulation results based on the IEEE 30-bus system demonstrate that ESS participation in FRP services significantly reduces FRU clearing frequency and prices during sharp net load increase periods, particularly under high renewable penetration scenarios. The high responsiveness of ESS substantially enhances system flexibility and stability. Furthermore, while ESS participation marginally increases electricity market prices, it synergistically improves regulatory capacity of the system.
