论文摘要
能源存储在提供电力系统的灵活性方面具有巨大的潜力，以满足关键的峰值需求，从而降低了整体发电成本，从而稳定了电价。在这项工作中，我们利用独立系统运营商（ISO）作为公共资产进行投资和管理存储的机会，这可以系统地为公众提供利益。假设有二次生成成本结构，我们使用参数分析来研究ISO的经济调度问题，鉴于存储投资数量的变化。这项投资对用户的预期有益。但是，它可能不一定使所有人受益。我们采用边际系统成本影响（MCI）的概念来衡量每个用户的福利，并显示其与常规位置边际价格的关系。我们发现MCI有趣的收敛特性。此外，我们执行$ k $ - 均值聚类，以对用户进行分类，以进行有效的用户分析，并对原型和IEEE测试系统进行数值研究，以验证我们的理论结论。
Energy storage has exhibited great potential in providing flexibility in power system to meet critical peak demand and thus reduce the overall generation cost, which in turn stabilizes the electricity prices. In this work, we exploit the opportunities for the independent system operator (ISO) to invest and manage storage as public asset, which could systematically provide benefits to the public. Assuming a quadratic generation cost structure, we apply parametric analysis to investigate the ISO's problem of economic dispatch, given variant quantities of storage investment. This investment is beneficial to users on expectation. However, it may not necessarily benefit everyone. We adopt the notion of marginal system cost impact (MCI) to measure each user's welfare and show its relationship with the conventional locational marginal price. We find interesting convergent characteristics for MCI. Furthermore, we perform $k$-means clustering to classify users for effective user profiling and conduct numerical studies on both prototype and IEEE test systems to verify our theoretical conclusions.
