By comparing the simulation results with the actual parameters of the PV module in reality, we can determine whether the PV module has faults. This fault detection method based on mathematical model not only improves the accuracy of fault detection, but also provides strong support for the maintenance and optimization of PV system. Fig. 5.
Current methodologies can be divided into two categories: The first one identifies photovoltaic (PV) defects, whereas the second one categorizes the specific sort of fault in a photovoltaic (PV) system. The literature has proposed various suggestions for fault identification.
The primary aim of this work is to develop a ML-based methodology for identifying and classifying the faults in photovoltaic systems. The proposed method, known as Fault Detection and Classification (FDC), is not affected by environmental conditions because it relies on the current and voltage parameters of solar PV systems.
This paper aims to address limitations identified in the literature on fault detection in photovoltaic (PV) systems. These limitations include a narrow focus on a limited number of fault types, the complexity of existing models which hinders real-time implementation, and insufficient consideration of environmental variability.
