In this paper, we propose a semicentralized voltage control method utilizing past voltage measurements obtained with sensors in a distribution network (DN) to improve the voltage control performance of a single‐step voltage regulator (SVR). In this method, the SVR basically performs autonomous voltage control referring to the control parameter, the reference voltage, but the parameter is updated with a specific interval via communication. To determine a time series of the reference voltage using the past voltage measurements, the simple averaging method and the probabilistic weighting method are considered. The effect of these methods on the voltage control performance is evaluated with a power flow simulation using a realistic 6.6 kV DN model with photovoltaic systems. The results show that the proposed semicentralized SVR control with these advanced parameter‐updating methods dramatically mitigate voltage violation compared to the conventional SVR operation in which the constant reference voltage is used for 1 year. © 2020 Institute of Electrical Engineers of Japan.

基于配电网过去电压测量的基于SVR的半集中式电压控制方法

在本文中，我们提出了一种半集中式电压控制方法，该方法利用过去在配电网（DN）中使用传感器获得的电压测量结果来改善单步稳压器（SVR）的电压控制性能。在该方法中，SVR基本上参考控制参数即参考电压执行自主电压控制，但是该参数通过通信以特定间隔进行更新。为了使用过去的电压测量值确定参考电压的时间序列，需要考虑简单的平均方法和概率加权方法。使用光伏系统的实际6.6 kV DN模型，通过潮流模拟评估了这些方法对电压控制性能的影响。结果表明，与使用恒定参考电压1年的常规SVR操作相比，采用这些高级参数更新方法的半集中式SVR控制可显着缓解电压违规。©2020日本电气工程师学会。由John Wiley＆Sons，Inc.发布
