Islanding Detection Scheme for Single-Phase Grid-Connected Solar Photovoltaic System using Support Vector Machine

Abstract

The event of isolated islands is not planned because it poses a risk to the safety of utility service workers, and the production and electrical power installations are damaged due to the asynchronous shutdown. Detection of islanding in the distributed generation (DG) system is a challenging issue with several security and protection issues. Once the DG is disconnected from the main source, efficient island detection is necessary to effectively detect the island. In this paper, the author examined the different problems related to single-phase photovoltaic (PV) systems connected to the network under island conditions. The chief goal of this paper is to detect and classify all possible islanding scenarios by developing a trained dataset and a feature extraction process. Simulation results from MATLAB/Simulink toolbox are used to determine the islands operating conditions.
