Abstract

This paper proposes and compares two effective approaches to deploy low-voltage advanced voltage control devices connected at edge-of-grid to improve voltage regulation. The goal is to determine effective locations for deploying these devices to eliminate undervoltage violations during heavy loading conditions. Two commercially available devices, namely universal power flow controller and static var compensator, are studied in this paper. Practical limitations of installation space and device ratings are considered in determining the locations. The device specifications, characteristics, and modeling are also discussed in detail. The efficacy of the proposed methods is validated by simulations on a distribution circuit model of a utility with actual load profile information. Additional analysis provided on the device deployment offers insights into device placement under different application considerations. The results showed that the proposed methods are effective in mitigating undervoltage violations, reducing voltage unbalance and improving voltage regulation overall.

电网边缘电压控制:器件建模、策略放置和应用考虑

本文提出并比较了两种部署在电网边缘连接的低压先进电压控制装置以改善电压调节的有效方法。目标是确定部署这些设备的有效位置，以消除重载条件下的欠压违规。本文研究了通用潮流控制器和静态无功补偿器这两种市售装置。在确定安装位置时，要考虑安装空间和设备额定值的实际限制。详细讨论了器件的规格、特点和建模。通过对某电力公司的配电电路模型进行仿真，验证了该方法的有效性。提供的关于设备部署的附加分析提供了对不同应用程序考虑下的设备放置的见解。结果表明，所提出的方法在减轻欠压违规、减少电压不平衡和改善整体电压调节方面是有效的。
