Optimization of Photovoltaic System Protection: Voltage Dip Management with Integration of Recloser Settings

Abstract

This study aims to optimize the protection of photovoltaic (PV) systems against electrical disturbances, particularly voltage dips. The objective is to develop new methods for analyzing and managing these disturbances, which affects the power quality in electrical networks and causes the automatic disconnection of PV systems, leading to production losses and plant malfunctions. In addition, voltage dips represent a major challenge for industrial sectors, where they can cause production interruptions and process malfunctions, leading to economic losses and product quality degradation. This research proposes a method for real-time detection of voltage dips, by integrating the recloser settings within the monitoring system. This approach makes it possible to distinguish temporary outages, related to reclosing, from prolonged outages, thus avoiding unnecessary disconnections of PV systems. The method's performance has been validated by simulations carried out in the MATLAB/SIMULINK environment.
