Special Issue Information

In the last years, photovoltaic systems are receiving a growing research attention due to their fundamental role in energy efficiency worldwide. The last research activities on photovoltaic systems are mainly focused on modeling, sizing and control of stand-alone and grid-connected photovoltaic systems, on centralized Maximum Power Point Tracking (MPPT) and distributed MPPT, on photovoltaic arrays reconfiguration, on storage sizing and control optimization, on detection of mismatching operating conditions, fault diagnosis and maintenance programming, on prediction and modeling of solar radiation, and output power plants forecast. On the basis of these considerations, the goal of this topic collection is to focus on the latest theoretical studies, numerical algorithms, scientific results and applications of photovoltaic systems. This topic collection has the objective of bringing together scientists adopting several approaches and working on the above topics and of promoting and sharing as much as possible top-level research in the field of photovoltaic systems.

Detection and Classification of Faults in a Photovoltaic System—A New Hybrid Algorithm

Four main types of faults can occur at the DC side of any Photovoltaic System (PVS). These faults are quite dangerous and can cause permanent damage to the photovoltaic modules if not addressed promptly. The faults include open circuit, short circuit, degradation, and partial shading. Short circuit faults are classified into line-to-line (L-L) and line-to-ground (L-G). Detecting these faults requires specialized algorithms. This paper tackles this complex issue through (1) fault-finding equations and the placement of current sensors, and (2) a new hybrid algorithm based on data from the fault-finding equations and current sensors. Numerous simulations using PSIM 2021 were conducted to verify this proposed solution. The hybrid algorithm presented here is original compared to previous studies. It is easy to understand, responds quickly, and can be implemented in systems with photovoltaic arrays of any size.
