In this article, a novel distributed coordinated control framework is proposed to handle the uncertain voltage violations in active distribution networks. It addresses the problem of coordination of different types of devices in a distributed manner. In our control design, on-load tap changers (OLTCs) are firstly employed to handle the potential voltage violations based on the prediction of renewable outputs and load variations. During real-time operation, once an unmanageable voltage violation is detected, the reactive power of distributed energy resources (DERs) will be coordinated immediately to provide fast corrective control. The control schedules of OLTCs are calculated by solving a multitime-step constrained optimization problem via the alternating direction method of multipliers, whereas the reactive power injections of DERs are determined by a novel online distributed algorithm. The effectiveness of the proposed control framework is verified on the modified IEEE 34-bus and 123-bus test feeders.

配电网调压的分布式协调无功功率控制

在本文中，提出了一种新颖的分布式协调控制框架来处理有源配电网中不确定的电压违规。它解决了以分布式方式协调不同类型设备的问题。在我们的控制设计中，首先基于可再生输出和负载变化的预测，采用有载分接开关（OLTC）处理潜在的电压违规。在实时操作期间，一旦检测到无法控制的电压违规，将立即协调分布式能源（DER）的无功功率，以提供快速的纠正控制。OLTC的控制计划是通过乘数的交替方向方法解决多时步约束优化问题来计算的，DER的无功功率注入是通过一种新颖的在线分布式算法确定的。改进的IEEE 34总线和123总线测试馈线验证了所提出的控制框架的有效性。
