“…Steady state oscillations can be reduced by reducing the step size, but system tracking speed gets slower down if step size gets reduced Messalti et al (2017). Many research contributions available in literature to overcome these issues with the introduction of variable step size MPPT algorithms Hosseini et al (2013), Alkhawaldeh and Bhuiya (2021), Liu et al (2008), Tian et al (2014), Husain et al (2017), Chuang et al (2020), Suntio and Kuperman (2019), Kumar et al (2019), in which step size is regularly changed according to the environmental conditions and provides a simple and quick response with low oscillations. The step size of this method is mathematically written as shown in Equation 9 and Equation 10.…”

In past few decades, solar energy plays a vital role in energy production among the different renewable energy resources. In shaded/unshaded photovoltaic (PV) systems, tracking of maximum power under different environmental conditions is provided by maximum power point tracking (MPPT). In recent years many works available on different types of MPPT techniques to track maximum power from PV systems with own pros and cons. This article comprehensively reviews the different traditional methods like perturb and observation (P&O), open circuit voltage (OCV), short circuit current (SCC), hill climbing (HC), incremental conductance (IC). Also recall the advanced MPPT techniques like particle swarm optimization (PSO), grey wolf optimization (GWO), cuckoo search (CS), artificial neural networks (ANN), fuzzy logic controller (FLC) available in literature. This review is conducted based on implementation, accuracy, tracking speed, cost, merits, and demerits of each technique. Traditional MPPT methods can’t able to track global maximum power point under partial shaded conditions and exhibits less efficiency when compared with advanced soft computing methods. Hybrid methods provide good efficiency and performance than traditional and advanced methods. Authors powerfully confirm that this article offers convenient information’s to enthusiastic engineers and new researchers those who are all working in solar PV systems.

“…Saxena et al introduced a loop center-line idea-based MPPT of P&O technique, wherein, the iteration number is reduced and MPP is reached quickly [15]. A new self-adjusting disturb-disturb algorithm was proposed by Alkhawaldeh et al in which a precise change step size is estimated via the Newton-Raphson program, which is a simple design [16]. Zhang et al introduced the mixing technique based on repetition learning and the P&O method, which can eliminate the vibration of the steady-state and abnormal signals, further firmly control MPP [17].…”

This research explored the independent solar power system (ISPS), including the maximum power point tracking (MPPT) technology and the DC (direct current) to AC (alternating current) full-bridge inverter (FBI) control technology. This study combined the perturb and observe (P&O) algorithm based on the output voltage control strategy and the proposed optimized FBI control strategy to the ISPS. The proposed variable frequency and variable duty cycle (VFVDC) optimized FBI control strategy had adjustable frequency and duty cycle. The proposed VFVDC control strategy was compared with the sinusoidal pulse width modulation (SPWM). When the output of FBI was at a low voltage level, the operating frequency was 10 kHz. Conversely, when the FBI gave a high voltage level output, the operating frequency was 1 kHz. This control improved the switching loss of 4 power MOSFETs in the FBI and thus improved the performance with a low harmonic amount. To further verify the explored system, this study used MATLAB to compare the proposed control strategy and SPWM control method. The simulation results verified that the proposed control strategy total harmonic distortion (THD) = 1.02% was better than the SPWM control method THD = 3.23%, then the low pass filter (LPF) volume was reduced. Finally, the actual ISPS was used for actual measurement and verification. The proposed control strategy had a low harmonic level, can operate stably and effectively, and thus be used for the actual fulfillment of electricity needs.
