论文摘要
这项工作旨在量化利用储能来降低电力系统的能源发电成本的好处。在第一个优化问题旨在找到最小化运营成本的最佳存储时间表的情况下，提供了一个两倍的优化框架。由于操作成本取决于存储容量，因此制定了第二个优化问题，目的是寻找要部署的最佳存储能力。尽管总的来说，这些问题难以解决，但我们为参数性需求概况的成本节省提供了下限。使用来自ISO新英格兰的现实世界需求数据在数值上进行了优化框架。数值结果表明，储能可以将能源发电成本降低至少2.5％。
This work seeks to quantify the benefits of using energy storage toward the reduction of the energy generation cost of a power system. A two-fold optimization framework is provided where the first optimization problem seeks to find the optimal storage schedule that minimizes operational costs. Since the operational cost depends on the storage capacity, a second optimization problem is then formulated with the aim of finding the optimal storage capacity to be deployed. Although, in general, these problems are difficult to solve, we provide a lower bound on the cost savings for a parametrized family of demand profiles. The optimization framework is numerically illustrated using real-world demand data from ISO New England. Numerical results show that energy storage can reduce energy generation costs by at least 2.5 %.
