Common analysis methods include equivalent circuit models, maximum power point tracking algorithms, etc. The principle of using the hybrid method to detect photovoltaic panel faults is to combine the advantages of intelligent method and analytical method, aiming to improve the accuracy and robustness of photovoltaic panel fault detection.
PV Panel Fault Detection PV panel fault detection is a technique that detects and diagnoses the failure of PV panels in solar PV systems. PV modules can suffer from common quality issues such as hot spots, cracks, and power degradation. These issues can impair the performance and lifespan of the components, and even pose safety risks [ 98 ].
PV panel overlay detection and PV panel fault detection are both directly related to the performance and efficiency of solar power generation systems. PV panel overlay detection aims to detect whether there are shelters or pollutants on the surface of PV panels.
Abstract: Photovoltaic (PV) power prediction is a key technology to improve the control and scheduling performance of PV power plant and ensure safe and stable grid operation with high-ratio PV power generation.
The detection of photovoltaic panel overlays and faults is crucial for enhancing the performance and durability of photovoltaic power generation systems. It can minimize energy losses, increase system reliability and lifetime, and lower maintenance costs.
Therefore, the timely removal of the overlays and maintaining the cleanliness of PV panels are essential to ensure the normal operation of the PV system and prevent these failures. It is also imperative to conduct PV panel fault detection along with PV panel overlay detection [ 96, 97 ]. 3. PV Panel Fault Detection
