针对储能参与实时调度中因跨时段耦合导致的投标成本回收问题，提出最小化BCR的统一电价方案UP-BCR，仿真证明其较LMP大幅降低BCR和需求支付并保持零商业盈余。
AI 中文摘要
我们研究了在含储能资源的实时电力系统运行中，滚动窗口调度下的市场内统一电价和市场外投标成本回收（BCR）支付。由于荷电状态（SOC）的跨时段约束，储能运行在时间上相互耦合，现有的市场内节点边际电价（LMP）可能无法补偿储能的跨时段机会成本，从而触发市场外的BCR支付。我们证明，当被调度的发电机或储能具有高于需求侧投标的供给侧投标时，正的BCR是不可避免的。我们进一步识别了一个与SOC约束绑定相关的跨时段耦合指标，并实证表明，正的BCR仅在该指标活跃时出现，揭示BCR从根本上由跨时段耦合驱动。在仿真中，我们将一种最小化BCR的统一电价方案（UP-BCR）与现有实时电价方法在预测不确定性下进行比较，结果表明，在铜板模型中，UP-BCR相对于LMP大幅减少了BCR和需求支付，同时保持零商业盈余。
英文摘要
We study in-market uniform pricing and out-of-market bid cost recovery (BCR) payments in rolling-window dispatch for real-time power system operations with energy storage resources (ESRs). Due to intertemporal state-of-charge (SOC) constraints, ESR operations are temporally coupled, and existing in-market locational marginal pricing (LMP) may fail to compensate ESR's intertemporal opportunity costs, thereby triggering out-of-market BCR payments. We show that positive BCR is unavoidable when dispatched generators or ESRs have supply-side bids higher than the demand-side bid. We further identify an intertemporal coupling indicator associated with binding SOC constraints and demonstrate empirically that positive BCR arises only when this indicator is active, revealing that BCR is fundamentally driven by intertemporal coupling. In the simulation, we compare a BCR-minimizing uniform pricing scheme (UP-BCR) with existing real-time pricing methods under forecast uncertainty and show that UP-BCR substantially reduces BCR and demand payments relative to LMP while maintaining zero merchandising surplus in a copper-plate model.
