Tree Search Fuzzy NARX Neural Network Fault Detection Technique for PV Systems with IoT Support

Abstract: The photovoltaic (PV) panel’s output energy depends on many factors. As they are becoming the leading alternative energy source, it is essential to get the best out of them. Although the main factor for maximizing energy production is proportional to the amount of solar radiation reaching the photovoltaic panel surface, other factors, such as temperature and shading, influence them negatively. Moreover, being installed in a dynamic and frequently harsh environment causes a set of reasons for faults, de… Show more

“…The difference lies in the fault detection methods, which makes the works complimentary. While [39,40] uses fuzzy inference models yielding 98.2% accuracy with 16 combinations of shadowing, short circuit and open circuit, they cannot operate without disturbing the normal operation of the system, disconnecting the whole system to evaluate VxI curves or run the tree search algorithm.…”

“…The detection of system underperformance occurs when the predefined difference values are reached. Other studies have proposed alternative methods based on hardware redundancy [8], as well as the combination of standard statistical models with artificial intelligence techniques [35,36], specifically machine learning algorithms [37] and neural network algorithms [38]. The developed fault detection algorithms depend on the variations of the voltage and the power of the PV systems; thus, they are capable of detecting faulty PV modules and different conditions.…”

“…Other than that, there are also many difficulties in extending the application of solar photovoltaic systems as an electricity generation system, one of which is to timely detect the fault to preserve the efficiency and high productivity of the solar photovoltaic systems. In a newly presented research by (Natsheh & Samara, 2020), a new and efficient algorithm which is for fault diagnosis based on an artificial intelligent Nonlinear Autoregressive Exogenous (NARX) neural network and Sugeno fuzzy inference is proposed to isolate and identify the faults that may occur in a solar photovoltaic system. The fuzzy inference also includes the real sensed output power from the solar photovoltaic system as well as able to sense the surrounding condition.…”
