论文摘要
雄心勃勃的可再生投资组合标准激发了将储能资源（ESR）的纳入作为灵活性来源。尽管美国政府旨在促进ESR参与电力市场，但仍缺乏在市场设计方面的工作，但仍缺乏薪酬。在本文中，我们提出了一个新的能源市场清算框架，该框架结合了ESR系统。新的市场设计在计算上具有吸引力，因为它避免了具有互补性限制的混合式配方和配方。此外，与以前的市场设计相比，我们的市场使用虚拟链接的概念分解了ESR的运营，这些链接捕获了跨时间的能量的传递。虚拟链接表示揭示了可用于ESR运营的经济激励措施，并阐明了电力市场应如何报酬ESR。我们还探讨了ESR物理参数对市场行为的作用；我们表明，尽管能源和功率能力定义了每种ESR提供的灵活性，但存储/放电效率在ESR报酬和减轻市场价格波动方面起着基本作用。我们使用拟议的框架来分析ESR与独立系统运营商（ISO）之间的相互作用，并提供有关电网中ESR最佳部署策略的见解。
Ambitious renewable portfolio standards motivate the incorporation of energy storage resources (ESR) as sources of flexibility. While the United States government aims to promote ESR participation in electricity markets, work on market designs for properly remunerating ESRs is still lacking. In this paper, we propose a new energy market clearing framework that incorporates ESR systems. The new market design is computationally attractive in that it avoids mixed-integer formulations and formulations with complementarity constraints. Moreover, compared to previous market designs, our market decomposes the operations of ESRs using the concept of virtual links, which capture the transfer of energy across time. The virtual link representation reveals economic incentives available for ESR operations and sheds light into how electricity markets should remunerate ESRs. We also explore the role of ESR physical parameters on market behavior; we show that, while energy and power capacity defines the amount of flexibility each ESR can provide, storage charge/discharge efficiencies play a fundamental role in ESR remuneration and in mitigating market price volatility. We use our proposed framework to analyze the interplay between ESRs and independent system operators (ISOs) and to provide insights into optimal deployment strategies of ESRs in power grids.
