论文摘要
本文提出了一个双层优化框架，以研究价格制造电池储能系统（BESS）的最佳市场运营策略，在实时能源，旋转储备和作为绩效调节市场的付款中，特别关注BESS的过度调节市场参与者观察到的几个系统运营商观察到的过度调节市场参与以及电池降级对BESS市场活动的影响。精确的电池降解成本功能集成到Bess的战略招标模型中。提出了自动生成控制（AGC）信号调度模型，以在BI级框架中部署AGC信号。当考虑了电池降解和详细的AGC信号之后的活动之后，因此可以彻底研究BESS在频率调节市场中的运行特征。考虑系统的年度负载和辅助服务需求变化，对具有现实世界数据的合成系统进行了研究。还研究了BESS能力和替代成本对能源和辅助服务市场收入的影响。
This paper proposes a bi-level optimization framework to investigate the optimal market operation strategies of price-maker battery energy storage systems (BESSs) in real-time energy, spinning reserve, and pay as performance regulation markets, with a special focus on understanding BESS's excessive regulation market participation observed by several system operators and the impact of battery degradation cost on BESS market activities. An accurate battery degradation cost function is integrated into the BESS's strategic bidding model. An automatic generation control (AGC) signal dispatch model is proposed to deploy AGC signals in the bi-level framework. This enables thorough studies for BESS's operating characteristics in the frequency regulation market, when both battery degradation and detailed AGC signal following activities are considered. Case studies on a synthetic system with real-world data are performed to study interactions between BESS profit maximization and wholesale market operations, considering system annual load and ancillary service requirements variations. The impacts of BESS capacity and replacement cost on its revenue from energy and ancillary services markets are also investigated.
