“…If temperature of the shaded region excessively increases, hot-spot problem can be occurred. Thus, solar panels may be damaged due to this effect [18,19]. In order to prevent power decrement and inevitable damages, solar panels are combined with bypass diodes which are connected in reverse parallel to the series connected solar cells.…”

“…In both equations, the subscript M denotes a module, and subscripts without M denote an individual solar cell. As shown in Figure 2, if N SM presents the number of modules connected in a string and N PM represents the number of strings connected in parallel in a PV array, the output voltage and the current of the PV array under identical conditions can be defined as follows [41,42]:…”

Photovoltaic (PV) systems represent a clean, renewable source of energy that has non-linear current-voltage (I-V) and power-voltage (P-V) characteristics. To increase the efficiency, a PV system must operate at the maximum power point (MPP) to produce the maximum available power. Under uniform conditions, there is only a single MPP in the P-V curve of a PV system; however, determining the MPP is more complicated under partially shaded conditions (PSCs) because multiple peak power points exist. In recent years, various studies have been performed to obtain the highest peak power point under PSCs, which is referred to as the global maximum power point (GMPP). In this paper, a novel method based on mathematical analysis that reduces the search zone and simultaneously identifies the possible MPPs in the specified zone is proposed; this proposed method is called the dual search maximum power point (DSMPP) algorithm. To evaluate the effectiveness of the proposed method, simulation and hardware implementations are carried out. The results show that the search time of GMPP is significantly reduced and the GMPP is detected in the minimum amount of time with high accuracy and minimum oscillation in the power produced.

“…The shortcomings of the P&O and HC methods are overcome in the IC technique but it is complex to some extent and instability occurs in the expected output [6]. As in the OCV [7] and SCC techniques [8], the value of the proportionality constant depends upon the PV panel aging, so the performance degrades with the passage of time.…”

Abstract:Owing to the evolution of the smart grid, the emergence of hybrid power systems (HPSs), and the proliferation of plug-in-hybrid electric vehicles, the development of efficient and robust maximum power point tracking (MPPT) algorithms for renewable energy sources due to their inherent intermittent nature has overwhelmed the power industry.In this paper, an incremental conductance (IC) based Hermite wavelet incorporated neurofuzzy indirect adaptive MPPT control paradigm for a photovoltaic (PV) system in a grid-connected HPS is proposed. The performance of the proposed adaptive Hermite wavelet incorporated neurofuzzy MPPT control paradigm is validated through a comprehensive gridconnected HPS test-bed developed in MATLAB \ Simulink by comparison with an IC based adaptive indirect neurofuzzy Takagi-Sugeno-Kang (TSK) control scheme, IC based adaptive direct neurofuzzy TSK control system, IC based adaptive proportional-integral-derivative (adapPID) control scheme, and IC algorithm for PV systems.
