论文摘要
分布式能源（DER）在分销网络中的渗透不断提高，在传输和分销网络的运行中构成了新的挑战。但是，转换器连接设备（CIG）的可控性也揭示了有或没有经济激励措施的辅助服务的灵活操作和提供的机会。这项工作的主要范围是创建一个框架，以计算主动分配网络的操作灵活性，并使用它来解决传输系统操作员的集中式最佳功率流问题，尤其是电压稳定性余量最大化。提出了两种不同的方法来计算PQ平面中的柔韧性区域（FR），并将集中优化应用于简单且更复杂的传输测试系统和馈线配置。
The increasing penetration of Distributed Energy Resources (DER) in the distribution network creates new challenges in the operation of both the transmission and the distribution network. However, the controllability of the converter interfaced devices (CIG), also unveils opportunities for flexible operation and provision of ancillary services with or without economic incentives. The main scope of this work is to create a framework in order to calculate the operational flexibility of an Active Distribution Network and use it to address a centralized Optimal Power Flow Problem by the Transmission System Operator, and in particular the Voltage Stability Margin maximization. Two different approaches are proposed to calculate the Flexibility Region (FR) in the PQ plane, and the centralized optimization is applied to simple and more complex transmission test systems and feeder configurations.
