The meticulous monitoring and diagnosis of faults in photovoltaic (PV) systems enhances their reliability and facilitates a smooth transition to sustainable energy. This paper introduces a novel application of deep learning for fault detection and diagnosis in PV systems, employing a three-step approach.
A fault detection method for photovoltaic module under partially shaded conditions is introduced in . It uses an ANN in order to estimate the output photovoltaic current and voltage under variable working conditions. The results confirm the ability of the technique to correctly localise and identify the different types of faults.
Results show that the method is able to detect faults in a PV array, and it was demonstrated experimentally for a SS-PVA. In a fault detection method based on WT and ANN is developed for an ungrounded PV system. The designed method is able to detect and localise GF and LL faults in a PVA.
In this paper, a selective input/output strategy is proposed for improving the life of photovoltaic energy storage (PV-storage) virtual synchronous generator (VSG) caused by random load interference, which can sharply reduce costs of storage device.
