The large-scale integration of renewable generation and the gradual decommissioning of conventional power plants has led to decreased availability of resources for providing services and support to the bulk transmission grid. This paper presents a novel methodology for providing support to the bulk transmission system through the control of thousands of small distributed energy resources (DERs), located in distribution systems. This control scheme is expected to serve jointly with other classical countermeasures against instability conditions. The proposed method is model-free, scalable, and does not rely on extensive communication infrastructure. It integrates an online method (New LIVES) to monitor the voltage stability status of the transmission system, a rule-based decentralized decision algorithm, and the local DER mechanisms implementing the control actions. The proposed approach is implemented on a combined transmission and distribution test system with over 4200 low-voltage buses and the dynamic simulation results illustrate its flexibility, practicality, and tractability.

协调分布式电源和灵活负载以支持紧急情况下的输电电压


可再生能源发电的大规模并网和传统发电厂的逐步退役导致为大宗输电网提供服务和支持的资源减少。本文提出了一种新颖的方法，通过控制位于配电系统中的数千个小型分布式能源（DER）来为大宗输电系统提供支持。该控制方案预计将与其他经典对策共同应对不稳定情况。所提出的方法是无模型的、可扩展的，并且不依赖于广泛的通信基础设施。它集成了监测输电系统电压稳定状态的在线方法（New LIVES）、基于规则的分散决策算法以及实施控制动作的本地DER机制。该方法在拥有4200多条低压母线的输配电联合测试系统上实施，动态仿真结果说明了该方法的灵活性、实用性和易处理性。
