“…Therefore, DC-DC power converters applied in the PV systems mainly regulate the system voltage. In addition, due to the voltage standardisation of the load to be supplied by the PV panel, a boost converter is necessary to regulate and adjust the voltage level using a pulse width modulation (PWM) to a maximum power point (MPP) 66 .…”

Solar energy is the powerhouse where all potential and classified renewable energies lug their sources. The energy transformation from the Sun to electricity requires an adequate control scheme to maximise the generated power and enhance the system efficiency. Besides, more than half of solar irradiation on conventional PV panels is lost. The PV/T modules have been introduced to convert the lost irradiation to heat. Thus, a systematic review of system components, development, and strategies for grid-connected solar Photovoltaics (PVs) plants is presented. Two solar PVs, traditional PV and thermal (PV/T), are evaluated. Each grid-tied PV component is considered a subsystem to analyse the potential improvement of grid-connected PVs. This is from solar resources to grid-tied PV inverter techniques. An intensive assessment of the system improvements is presented to evaluate PV plants’ benefits, challenges, and potential solutions. The improvement trends for the novel generation of grid-connected PV systems consist of applying innovative approaches. It is also found that intelligent strategies optimally ensure the overall efficiency of grid-tied PVs using real-time control and measurement under innovative applications and technologies. These methods effectively assist in enhancing grid-tied diverse solar power approaches. Therefore, this paper would offer a significant foundation for advanced research into the subject of grid-tied PV and PV/T and their innovation and/or technology development.

“…All the MPPT techniques, as described in Table 7, are expensive except the one-cycle control (OCC) technique. While all the MPPT techniques require a tuning parameter, the sliding-mode-based MPPT technique does not need it 66 . The intelligent MPPT techniques contain various strategies to track the MPP.…”

“…The tracing of the MPP of the power and the voltage (P-V) profile of the entire PV field may collapse due to the existence of by-pass diodes, which causes such a P-V characteristic to have multiple peaks. In this instance, MPPT techniques are unable to track to exact MPP [48][49][50][51][52].…”

Photovoltaic (PV) solar energy is a very promising renewable energy technology, as solar PV systems are less efficient because of climate conditions, temperature, and irradiance change. So, to resolve this problem, two PV topologies are used, i.e., centralized and distributed PV systems. The centralized technique is quicker than the distributed technique in terms of convergence speed and a faster power tracking approach. In the event of uniform irradiance, the centralized system also has the benefit of supplying superior energy, but in PS scenarios, a huge amount of energy is lost. However, the distributed approach requires current and voltage measurements at each panel, resulting in a massive data set. Nevertheless, in the event of shading circumstances, the distributed technique is highly effective because a modular level power electronics (MLPE) converter is used. While in a centralized PV system, there is only a single DC-DC converter for the whole PV system. In this research work, a DFO-based DC-DC converter is designed for modular level, with an ability to perform a rapid shutdown of the module under fire hazard conditions, troubleshooting, and monitoring of a module in a very efficient way. The robustness of the proposed MPPT DFO algorithm is tested with different techniques such as Cuckoo Search (CS), Fruit Fly Optimization (FFO), Particle swarm optimization (PSO), Incremental conductance (InC), and Perturb and observe(P&O) techniques. The proposed technique shows better results in terms of MPPT efficiency, dynamic responsiveness, and harmonics. Furthermore, the result of MLPE and the centralized system is verified by using the Helioscope with different inverter companies like SMA, Tigo, Enphase, Solar edge, and Huawei. The results prove that MLPE is a better option in the case of shading region for attaining the maximum power point.

“…In photovoltaic power generation systems, sudden changes in weather and local shadows, where are multiple peaks in the output power characteristic curve of PV arrays. Traditional MPPT control algorithms, for example Fractional Open Circuit Voltage (FOV), Perturb and Observer (P&O), and Increments Conductivity (INC) [3,4,[5][6]7], are easy to fall into local extremes, resulting in inefficient tracking and no longer applicable. Therefore, the research on the MPPT algorithm according to intelligent colony optimization, that is, the social behavior mechanism that simulates the animal colony in the nature to find food in a certain cooperative way, and learning from each member of the group their own and other members experiences, you can continuously change the direction of your search, has become a hot spot by improving and optimizing the intelligent colony algorithm to improve the efficiency of tracking power.…”

MPPT control study of improved Gray Wolf algorithm (GWO) according to Levy flight and greedy strategy: Solving the problems of maximum power point tracking (MPPT) with traditional Gray Wolf algorithm (GWO) under local shadows of photovoltaic arrays and sudden environmental changes, which is easily trapped in local optimum and has a slow convergence rate, and poor solution accuracy, a improved gray wolf algorithm (LGWO) according to Levy flight and greedy strategy is presented. It is used for the first time for maximum power point tracking under partial shadow and dynamic shadow changes of photovoltaic array. It is based on the traditional Grey Wolf algorithm (GWO), it introduces Levy’s flight search strategy, improve the algorithm of global search ability, expands search range, and filters optimal range through greedy strategy to further accelerate the convergence speed. MPPT simulation model according to Boost circuit is built using MATLAB/Simulink to verify. Experiments in the presence of partial shadows and shadow mutations. The results of simulation experiments show that the ameliorated Gray Wolf algorithm (LGWO) improves the tracking accuracy of MPPT by 0.03%, improves the convergence speed by 1.1 times and is more stable after reaching the maximum number of iterations. This verifies the feasibility and superiority of the ameliorated Grey Wolf algorithm in maximum power point tracking control.
