“…However, this algorithm has the following shortcomings: (1) under the partial shading condition (PSC), the actuating point can become stuck at the local peak power point without escape [37]; (2) at a steady-state irradiance level, the actuating point will vibrate near the MPP [21]; (3) with the rapid change in irradiance levels, the actuating point cannot capture the MPP in time [22]; (4) the actuating point is close to the MPP, and the convergence speed is slow [22].…”

This research proposed a novel global maximum power point tracking (global-MPPT) algorithm. The proposed algorithm eliminates the perturbation and observation (P&O) technique disturbance problem that the power point will be stuck at the local peak power point under a partial shading condition (PSC). The proposed global-MPPT algorithm detects the photovoltaic module (PV-M) environment irradiance level by the relationship between the output power and voltage of the PV-M. In the proposed algorithm, the important parameter w is determined by the PV-M output power and irradiance level, which is also the compensation parameter that corresponds to the relationship of temperature. The proposed global-MPPT algorithm is aimed to predict the best duty cycle of the global-MPPT based on the irradiance level, parameter w, PV-M output voltage, and load, and then achieve the maximum power point (MPP) quickly and accurately. The measurement results under UIC and PSC verify that the proposed global-MPPT technique performs better than the particle swarm optimization (PSO) and P&O techniques. This research contributes to the proposed method that can find the global-MPP in time based on the irradiance level, temperature, and load.

“…It involves disrupting the duty cycle of a power converter to affect P pv for MPPT. (18) However, the disruptive character of the algorithm causes the actuating point to oscillate around the MPP, resulting in suboptimal power output. In addition, the algorithm compares the power points only with the adjacent power points.…”

A novel algorithm for maximum power point tracking (MPPT) in solar power generation systems was proposed and compared with the conventional methods of hill climbing (HC) and perturbation and observation (P&O) algorithms. The two conventional algorithms are prone to divergence under low irradiance levels (<150 W/m 2 ), resulting in difficulties in MPPT. The MPPT technique proposed in this study integrates irradiance change per unit area threshold control (ICPUATC) into the P&O algorithm. The proposed algorithm can facilitate quick and precise convergence at the maximum power point (MPP) for a photovoltaic module under a low irradiance level of 65 W/m 2 . The proposed and HC algorithms were compared for irradiance levels of 480, 140, and 65 W/m 2 , and the proposed algorithm consistently yielded better results than did the HC algorithm.This version has been created for advance publication by formatting the accepted manuscript. Some editorial changes may be made to this version.

The greatest amount of electricity that is accessible must always be extracted in order to operate photovoltaic (PV) systems effectively. Determining the maximum available power is a time-varying challenge since environmental factors like irradiation, temperature, and shading can change fast. Maximum power point tracking (MPPT) strategies are suggested in order to extract the maximum possible power and track the ideal power point under these varied environmental conditions. The use of MPPT to extract the most power is essential for creating effective PV systems. Because it is clean and pollution-free, solar energy has gained a lot of interest. However, the solar array cannot operate uniformly at the maximum power point due to the partially shadowed state, resulting in a significant power loss. These MPPT approaches have a number of drawbacks and limitations, especially when there is partial shadowing brought on by uneven environmental circumstances. An overview of various maximum power point tracking (MPPT) methods for photovoltaic (PV) systems is given in this paper. This thorough analysis of MPPT techniques seeks to give electricity companies and researchers a resource and direction for choosing the optimum MPPT technique for typical operating and partially shaded PV systems based on efficiency and financial viability.
