论文摘要
在分配馈线中增加分布式能源（DER）的集成在分配传输互连时提供了前所未有的灵活性。有了新的FERC 2222订单，允许DER聚合参与能源市场。为了使市场参与，这些虚拟发电厂需要提供其生成成本曲线。本文提出了有效的优化公式和解决方案方法，用于表征每小时的表征以及多个时间段的成本曲线，用于具有较高渗透率的分配系统。在得出这些成本曲线时，要考虑网络和DER约束，它们使主动分配系统能够竞标电力市场。衍生线性和二次成本曲线的问题是因为强大的优化问题和可拖动的重新制定/解决方案算法而提出的，以促进有效的计算。拟议的配方和溶液算法在具有较高柔性资源的逼真的测试馈线上进行了验证。
Increasing integration of distributed energy resources (DERs) within distribution feeders provides unprecedented flexibility at the distribution-transmission interconnection. With the new FERC 2222 order, DER aggregations are allowed to participate in energy market. To enable market participation, these virtual power plants need to provide their generation cost curves. This paper proposes efficient optimization formulations and solution approaches for the characterization of hourly as well as multi-time-step generation cost curves for a distribution system with high penetration of DERs. Network and DER constraints are taken into account when deriving these cost curves, and they enable active distribution systems to bid into the electricity market. The problems of deriving linear and quadratic cost curves are formulated as robust optimization problems and tractable reformulation/solution algorithm are developed to facilitate efficient calculations. The proposed formulations and solution algorithm are validated on a realistic test feeder with high penetration of flexible resources.
