Fault detection and diagnosis techniques for photovoltaic systems: Trends, challenges and recommendations

​

Faults in any components (modules, connection lines, converters, inverters, etc) of photovoltaic (PV) systems (stand-alone, grid-connected or hybrid PV systems can seriously affect the efficiency, energy yield as well as the security and reliability of the entire PV plant), if not detected, quickly enough. In addition, if some faults persist (eg. arc fault, ground fault and line-to-line fault) they can lead to risk of fire. Monitoring, fault detection and diagnosis (FDD) methods are indispensable for reliability, efficiency, and safety of the PV plant. In this talk, the types and causes of PV systems failures will be presented, then some methods proposed in the literature for monitoring, FDD of PV systems will be also discussed. Special attention will be paid to methods that can accurately detect, localize and classify possible faults occurring in a PV array. Advantages and limits of FDD methods in terms of feasibility, complexity, cost-effectiveness and generalization capability for large-scale integration, as well as the applications of artificial intelligence techniques will be also discussed in this talk. The conclusion of the talk will highlight the trends, challenges and recommendations.
