As electricity storage deployments grow—due to decreasing costs and increasing grid flexibility requirements—market frameworks governing their dispatch and remuneration are a growing area of interest and importance. For example, the recent Federal Energy Regulatory Commission Order 841 instructs independent system operators to remove barriers of entry for storage assets. This paper reviews electricity market rules to inform an accurate representation of storage bidding behavior in day-ahead (DA) and real-time (RT) electricity markets. Storage dispatch strategies are explored using production cost and price-taker models to address two related research questions: (1) will storage assets receive the highest remuneration by bidding into DA markets, bidding into RT markets, or redispatching bids in both markets and (2) how accurate must forecast information be for a redispatch strategy to improve remuneration? Results show that with sufficient ability to forecast prices, redispatching a DA schedule in the RT takes advantage of both markets: a longer dispatch horizon as well as more volatile prices.

仓储调度对电力市场收入的影响

随着电力存储部署的增长(由于成本降低和电网灵活性要求提高),用于管理其调度和报酬的市场框架越来越引起人们的关注和重视。例如,最近的《联邦能源管理委员会命令841》指示独立系统运营商消除存储资产的进入壁垒。本文回顾了电力市场规则,以准确表示日前(DA)和实时(RT)电力市场中的存储招标行为。利用生产成本和价格接受者模型探索了仓储调度策略,以解决两个相关的研究问题:(1)竞价至DA市场,竞标RT市场,将使仓储资产获得最高的报酬;或重新分配两个市场中的出价;(2)预测信息对于重新分配策略以提高薪酬而言必须有多准确?结果表明,在具有足够的价格预测能力的情况下,在RT中重新分发DA计划可以同时利用两个市场:较长的调度范围和更易波动的价格。
