Title
New Methods Of Islanding Detection For Photovoltaic Inverters
Abstract
In a distribution network with the presence of PV systems, islanding phenomena can occur. Such isolated islands may cause a serious danger for workers and equipment. Therefore, islanding must be detected and the islanded PV systems must be disconnected from the principal network. This paper gives a review of different islanding detection methods for grid-connected PV inverters. These methods can be divided into three categories: passive methods, active methods and methods with communications. In order to improve the islanding detection performance, this paper proposes two new methods of islanding detection for PV inverters. The first proposed method is based on the rate of change of Voltage Unbalance (RoCoVU) weighted by the rate of change of Frequency (RoCoF). The second proposed method is based on the rate of change of Voltage Unbalance (RoCoVU) weighted by the rate of change of Reactive Power (RoCoQ) and the rate of change of Frequency (RoCoF). In order to evaluate the performance of the proposed methods, simulations are carried out. The results obtained by simulations have shown the advantages of the proposed methods.
