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.
Dr. Adel Mellit is a professor of renewable energy at the faculty of sciences and technology, Jijel University, Algeria. He received the M.Sc.Eng., and Doctorate degrees , both Electronics from the University of Sciences Technologies (USTHB) Algiers in 2002 and 2006 respectively. Research interests of Dr. Adel Mellit focus on the application of the artificial intelligence techniques in photovoltaic systems and micro-grids, control, fault diagnosis, optimisation and real time integration applications. He has authored and co-authored more than 90 papers in international peer reviewed journals (mostly in Elsevier), and papers in conference proceedings (Mostly in IEEE) mainly on photovoltaic systems and six book chapters. He is the director of renewable energy laboratory at Jijel University and an associate member at the ICTP Trieste (Italy). He is actually serving on the editorial board of Renewable energy and Energy journals (Elsevier Ltd).
