Abstract

The high penetration of Distributed Generation (DG) in the low-voltage distribution grid has raised several concerns in recent years, mainly regarding overvoltage at the buses caused by the reversal of active power flow. In order to solve this problem, this work proposes an adaptation of the Volt-VAr Extremum-Seeking (Volt-Var-ES) method, which, in addition to promoting voltage regulation, also minimizes active losses in the network. This approach is framed within the concept of local Volt-VAr control since it requires only local measurements and does not depend on an accurate grid model. The IEEE European Low Voltage Test Feeder was used as the test network, with some adaptations to bring it closer to the Brazilian reality. The adapted method was applied in several allocation scenarios and at different levels of DG penetration, and its results were compared with those of the conventional Volt-VAr method, presented in IEEE 1547:2018. The simulations showed that the adapted Volt-VAr Extremum-Seeking method satisfactorily regulates the grid voltage and reduces active losses compared to the conventional Volt-VAr, generating financial savings for utilities and avoiding financial losses for photovoltaic (PV) system owners due to active power curtailment.

低压配电网电压调节与损耗最小化的自适应v - var极值求法

近年来，分布式发电在低压配电网中的高渗透引起了人们的关注，主要是有功潮流反转引起的母线过电压问题。为了解决这一问题，本工作提出了一种自适应的Volt-VAr极值寻求（Volt-VAr - es）方法，该方法除了促进电压调节外，还可以最大限度地减少网络中的有功损耗。这种方法是在局部电压-电压控制的概念框架内，因为它只需要局部测量，而不依赖于精确的电网模型。IEEE欧洲低压测试馈线被用作测试网络，并进行了一些调整，使其更接近巴西的实际情况。将该方法应用于几种分配场景和不同DG渗透水平下，并将其结果与IEEE 1547:2018中提出的传统Volt-VAr方法的结果进行了比较。仿真结果表明，与传统的Volt-VAr方法相比，该方法能较好地调节电网电压，降低有功损耗，为公用事业公司节省了资金，避免了光伏系统业主因有功削减而造成的经济损失。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
