“…A series of configurations for the PV arrays are considered in this section to more broadly and robustly examine the capability of the proposed fault‐tolerant control strategy. These configurations are established in the literature [35, 36] and all cases considered in this section, are subject to a shading fault of five parallel strings which occurs at time t = 1.5 s following the model initialisation up to t = 1 s. The results are presented as follows: Parallel configuration : this configuration refers to all PV modules to be assembled in parallel, as shown in Fig. 17 a .…”

Solar photovoltaic (PV) is a prominent technology for the generation of electricity and its utility is on the rise. The PVbased generation facilities are susceptible to faults which if mismanaged, can result in an interruption in the supply of load demand and damage to the system. Faults in PV systems are caused by a broad range of reasons and hence, it is crucial to situate a fault-tolerant system for reliable operation. This study proposes a fault-tolerant control strategy for power electronics inverters for the integration of PV systems into power systems. This is a supervisory mechanism designed to aid PV systems to continue their operation during faults. A computer simulation verifies the performance of the proposed control strategy under a series of common fault conditions assuming a wide range of configurations for the PV system and load variations.

Since the last decade, partial shading conditions (PSCs) and its adverse influences on photovoltaic (PV) system performance have received due attention. It motivates researchers to explore methods to diminish/disperse the shading effects and/or novel PV array configurations to sustain under PSCs. To diminish the effects of PSCs, this paper presents a comprehensive review of various PV array configuration models for PV systems and metaheuristic approaches for shade dispersion effectively. Different PV array modeling approaches are identified, emphasizing their benefits, inadequacies and categorized according to vital features such as shade dispersion and improved performance in terms of efficiency; fill factor (FF), and maxima power, minimized power losses (PL) primarily. Besides these various PV array configurations such as hybrid, reconfigured, mathematical/game puzzle based advanced configurations are uniquely discussed with the existing configurations. In the current scenario, the metaheuristic algorithms are explored and widely accepted by researchers due to the long wire length requirement for PV array reconfiguration. This paper discusses and deliberates recent developments in methods of solar PV performance enhancement that deserves further study. Overall, the present study is helpful for academicians and researchers in the committed solar power installation area.

“…To maintain the output power of a PV system at the maximum power point (MPP), maximum power point tracking (MPPT) techniques are commonly employed, such as variable universe fuzzy logic control considering temperature variability [9], power feedback method [10,11], perturb and observe method [12], and incremental conductance method [13]. This study integrated particle swarm optimization (PSO) with an existing conventional MPPT technique to prevent the output characteristic curve from producing more than two peaks, which might produce results that are constrained in local maxima and fail to track the actual MPP [14][15][16], when shading or failure occurs in PV module arrays. The proposed PSO algorithm employs a digital signal processor combined with a boost converter to achieve MPPT.…”

This study proposes a binary search-based fault detection system for photovoltaic (PV) modules to ameliorate the deficiencies in the existing fault detectors for PV module arrays. The proposed system applies a single-chip microcontroller to execute the binary search algorithm. Moreover, to overcome multi-node voltage detection and reduce the number of integrated circuit components, an analog switch is used to perform detection channel switching; the detection results are displayed on a software platform developed using Visual C#. The proposed system does not require learning to execute the fault diagnosis of PV module arrays and has advantages including high accuracy and low construction costs. Finally, to verify the feasibility of the proposed system, this study simulated the abnormal situations of actual modules and applied the binary search algorithm for maximum power point tracking to detect malfunctions of the PV module arrays.
