“…The multiple peaks may mislead; therefore, some algorithms are proposed to identify the global maximum power point (GMPP) [2]. The literature [3,4] has reported in a variety of ways, such as the number of PV system designs connected to the grid, PV array layout or reconfiguration, etc. The local maximum points may be chosen using conventional MPPT methods.…”

Partial shade on a photovoltaic (PV) array reduces output power because of mismatch losses. Therefore, selection of PV array configuration is one of the crucial factors to consider for maximum power output. The Triple-Tied-Cross-Link (TTCL) configuration used has lesser tied connection in contrast to the conventional Total-Cross-Tied (TCT) configuration. The performance of the TTCL configuration is further enhanced by applying Sudoku puzzles as a reconfiguration technique. Without changing the electrical connection, the Sudoku puzzle is used to arrange the physical placement of the modules in the PV arrays. By dispersing the shading impact over the array, the suggested arrangement reduces the amount of shade that dominates in any one row. The recommended Optimal Sudoku Puzzle (OSP)- based TTCL design's performance has been compared to the TTCL setup for the 9×9 PV array. Six partial shading patterns named Group-I to Group-VI are considered to analyze the performance of the proposed reconfiguration technique. The number of parameters such as global maximum power point (GMPP), open circuit voltage, short circuit current, mismatch loss, fill factor, and efficiency are measured to show its performance under different shading patterns. The numerical results show the effectiveness of the recommended OSP- based TTCL configuration technique. It is investigated that the numerical values in the case of shading pattern Group-III for the performance parameter GMP and fill factor have increased by 11.59% and 16.90 %, respectively, as compared to TTCL configuration. The mismatch loss (ML) was achieved with the lowest value, i.e., 21.98%, when compared to the TTCL (36.13%). The 9x9 PV array's efficiency in the proposed configuration is 13.33%, which is higher than that of TTCL (11.94%) arrangements. From the simulated results, the puzzle-based reconfiguration technique is found to be an optimal approach as compared to traditional configuration.

“…Many methods have been developed to determine the Maximum Power Point (MPP) under varying conditions [5][6][7]. Some of them are based on the well-known principle of perturb and observe (P&O) [8], others are based on sliding mode control [9][10][11][12], on artificial neural networks, or on fuzzy logic algorithms [1,2,7]. In [12][13][14], Maximum Power Voltage (MPV) based approaches are developed using a two-loop MPPT control scheme.…”

In this paper, a new Maximum Power Point Tracking (MPPT) control for a Photovoltaic (PV) system is developed based on both backstepping and terminal sliding mode approaches. This system is composed of a solar array, a DC/DC boost converter, an MPPT controller, and an output load. The Backstepping Terminal Sliding Mode Controller (BTSMC) is used via a DC-DC boost converter to achieve maximum power output. The stability of the closed-loop system is guaranteed using the Lyapunov method. This novel approach provides good transient response, low tracking error, and very fast reaction against solar radiation and PV cell temperature variations. Furthermore, chattering, which constitutes the main disadvantage of the classic sliding mode technique is eliminated. To show the effectiveness and robustness of the proposed control, different simulations under different atmospheric conditions are conducted in Matlab/Simulink.

The maximum power extraction using single integral sliding mode control scheme is established from the sliding mode control scheme. The sliding mode control (SMC) scheme extracts the maximum power during the partial shading weather conditions using the effective selection sliding surface duty cycle ratio in combination of dc/dc boost converter. This dynamic operation of sliding surface selection operation in partial shading conditions aids to enhance the solar panel efficiency compared to the other existing MPPT schemes. The effective dynamic operation of sliding surface mode control is designed using feedback loop control scheme to diminish the steady state voltage error of the solar panel, further to obtain the higher sliding duty cycle ratio. The dc-to-dc boost converter is made active using sliding duty cycle ratio as input gate signal boost converter switch. Hence, higher efficiency attains at higher sliding surface duty ration. This sliding surface duty ratio is limited in sliding mode MPPT control scheme and requires the necessary advancements to achieve the maximum duty cycle ratio. The single integral sliding mode control scheme (SISMC) offers the enhanced sliding surface duty cycle ratio with integration of voltage error obtained in SMC scheme. Therefore, the major application of SISMC compared to SMC scheme is the proposed SISMC schemeoffers the effective dynamic sliding operation using integrated steady state voltage error signal and allows to nullify the lacuna of maximum sliding duty cycle ratio. Hence, this paper aims to discuss the design and performance analysis of SMC scheme and proposed SISMC MPPT control scheme. To corroboratethe performance of the proposed SISMC MPPT scheme, the MATLAB / Simulink model was designed and verified. Also,this paper presents the comparison results of proposed SISMC MPPT schemes with the SMC scheme.
