“…Furthermore, if algorithm designers fail to account for these changes, a given working condition may fail. One can deduce that the most typical obstacles are the nonlinearity of PV features, variations in ambient conditions, and system functioning conditions [53][54][55][56][57][58][59][60].…”

Out of many renewable sources, solar energy sources that are clean, green, and emission-free have gained wide utilization despite their intermittency nature. Several solar photovoltaic (PV) panels are connected in series-parallel to achieve the energy demand. In such a system, it is possible that each panel operates differently due to uneven temperature and irradiation that results in uniform and partial shading conditions. Thus, a unique and efficient mechanism is required to extract maximum power from uniformly and partially shaded PV systems. Numerous maximum power point tracking (MPPT) methods have been developed to increase the efficiency and lifetime of photovoltaic systems. This study provides a unique, in-depth, and organized review of MPPT methods under four categories: classical, intelligent, optimization, and hybrid techniques. All possible selection benchmarks are considered to do a comprehensive review, which is not deliberated in the existing review literature. Based on the selection benchmarks, the advantages and disadvantages of each MPPT technique under different categories are summarized in tabulated form. To address the research gaps for further investigation in this field, a concise discussion is included at the end. This review article may find an accessible reference for engineers to understand the most useful MPPT method and to undertake extensive research in PV systems.

“…The global methods usually combine ICP with natureinspired optimization algorithms [24,25], such as particle swarm optimization [26,27], genetic algorithm [28,29], simulated annealing method [30,31], discrete cat swarm optimization [32], and coati optimization algorithm [33]. These methods can make ICP to jump out local minima in a probability, but it cannot theoretically guarantee the global optimal solution.…”

Profile registration is critical to rail wear measurement with line structured light, and the most popular registration method is iteration closest point (ICP). Unfortunately, ICP is often invalid in actual applications because it is easy to trap into local minima. To solve this problem, we propose a hybrid 2D-point-set registration method which combined ICP to branch and bound. In this way, we can ensure that the ICP algorithm converges to the global optimum. This strategy can achieve high-registration precision, but it suffers from large computation costs. To address this issue, we propose an acceleration scheme by sparsely sampling the point-set before registration to relieve computation burden. Extensive experiments are conducted to verify the precision, stability, and efficiency of our method. The results show that our method has superior precision and stability compared to the other typical profile registration methods. The ability to achieve fast registration speed which is suitable for dynamic measurement is another contribution of our work.

Partial shading of solar panels diminishes their operating efficiency and energy synthesized as it disrupts the uniform absorption of sunlight. To tackle the issue of partial shading in photovoltaic (PV) systems, this article puts forward a comprehensive control strategy that takes into account a range of contributing factors. The proposed control approach is based on using multi-string PV system configuration in place of a central-type PV inverter for all PV modules with a single DC-DC converter. This adaptation enhances overall efficiency across varying radiation levels. Also, the proposed technique minimizes the overall system cost by reducing the required sensors number by utilizing a radiation estimation strategy. The converter switching strategy is synthesized considering direct duty-cycle control method to establish the maximum power point (MPP) location on the P–V curve. The direct duty-cycle tracking approach simplifies the control system and improves the system’s response during sudden partial shading restrictions. To validate the effectiveness of the suggested MPPT method, two system configurations were constructed using MATLAB/SIMULINK software and assessed under various partial shading scenarios. Additionally, a multi-string system was subjected to real irradiance conditions. The sensor-less MPPT algorithm proposed achieved an impressive system efficiency of 99.81% with a peak-to-peak ripple voltage of 1.3V. This solution offers clear advantages over alternative approaches by reducing tracking time and enhancing system efficiency. The system findings undoubtedly support the theoretical scrutiny of the intended technique.
