在多区间经济调度中，基于SOC（State of Charge）竞价的储能系统参与批发市场会导致非凸成本，这就需要在市场出清中采用混合整数线性规划。我们表明，经济调度可以转化为标准的线性规划时，SoC相关的报价满足等递减成本比（EDCR）条件。这样的EDCR出价被证明是支持个人理性的所有市场参与者在日前的多时段经济调度下的位置边际定价和滚动窗口前瞻调度下的时间-位置边际定价在实时市场。一个数值例子来证明一个更高的利润率与SoC依赖的投标比，从SoC独立的投标。
Wholesale market participation of storage with state-of-charge (SoC) dependent bids results in a non-convex cost in a multi-interval economic dispatch, which requires a mixed-integer linear program in the market clearing. We show that the economic dispatch can be convexified to the standard linear program when the SoC-dependent bid satisfies the equal decremental-cost ratio (EDCR) condition. Such EDCR bids are shown to support individual rationalities of all market participants in both the day-ahead multi-interval economic dispatch under locational marginal pricing and the rolling-window look-ahead dispatch under temporal-locational marginal pricing in the real-time market. A numerical example is presented to demonstrate a higher profit margin with an SoC-dependent bid over that from an SoC-independent bid.
