Abstract—The paper contains a novel online fault diagnosis for distribution feeder with photovoltaic (PV) generation embedded. The aim of the research is to isolate and prevent system faults in Grid connected PV System. Firstly, a dynamic model of distribution feeder for fault. This paper reviews recent progress in fault detection, reliability analysis, and predictive maintenance methods for grid-connected solar photovoltaic (PV) systems. With the rising adoption of solar power globally, maintaining system reliability and performance is vital for a sustainable energy. Early fault detection and diagnosis of grid‐connected photovoltaic systems (GCPS) is imperative to improve their performance and reliability. Low‐cost edge devices have emerged as innovative solutions for real‐time monitoring, reducing latency, and improving response times. These guidelines set out the criteria that need to be considered when performing the inspection of a solar PV System to be connected to the distribution network.
