“…The steady-state efficiency of the method proposed in this paper is significantly better than the conventional P&O and adaptive P&O methods under various irradiance intensities, as shown in Figure 19 and Table 6 using the formula in (26). The transient efficiency is only slightly lower than the adaptive P&O method when the irradiance intensity decreases, but higher than Hence, we conclude that the control strategy proposed in this paper significantly improves PV system output efficiency compared to the conventional P&O and adaptive P&O methods and is particularly effective when the irradiation intensity is high.…”

With the conventional perturbation and observation (P&O) method, photovoltaic (PV) converters have long maximum power point (MPP) tracking times and three‐point oscillations at the steady state that can lead to output power losses and inefficiencies in grid connections. To overcome these drawbacks, a fast tracking and steady‐state‐oscillation‐free control strategy is proposed. The strategy first stores four random duty cycle values on the basis of the duty cycle variation characteristics of the PV panel power adjustment, then calculates the odd and even duty cycle difference and judges the steady state by varying the duty cycle difference threshold. The strategy next obtains the MPP duty cycle using a median filtering algorithm (MFA) to suppress the steady‐state oscillation and improves the tracking speed by resetting the appropriate duty cycle step according to the slope of the PV curve of the PV panel output and the corresponding adaptive coefficients. The proposed algorithm was simulated and experimentally validated under various irradiance conditions, and the results show that the algorithm can improve the PV panel output efficiency compared to both the conventional P&O and the adaptive P&O methods.

“…According to [26][27][28], the PV output voltage decreases when increasing the duty cycle. From Figure 3, we can see that the PV cell output power increases when it is on the right-hand side of MPP.…”

“…The testing site has rich sunlight and it is quite possible to install solar photovoltaic [11]. Because irradiation is intermittent, it is not possible for panels to generate continuous and even power [12]. Due to this, the battery is used to store the power produced by the panel, and the converter is the instrument used to transfer this power from the battery [13].…”

<span lang="EN-US">It's important to examine and handle the issue of green energy generation in inaccessible locations. Nonrenewable hybrid power has environmental and economic impacts. Reliable electricity and energy efficiency are priorities. Renewable energy that is eco-friendly and doesn't affect the environment. Solar and wind power, two ecologically benign and load-sharing-capable forms of renewable energy, are included in this technique. At the same time, solar power will keep the load voltage balanced and the system stable thanks to the inclusion of a DC-DC converter. The asynchronous generator has been selected because of its low maintenance needs and extended service life; nevertheless, the voltage on the load side is unbalanced when this machine is in operation. An asynchronous generator can be a viable alternative to well-developed synchronous generators for use in wind turbines or small hydro generators because they have relatively inexpensive costs, are simple, require inadequate maintenance, possess adequate resistance to wear and tear, and have reduced overload damage. It is difficult to maintain a continuous supply of energy in faraway regions because of the lack of related work in the power distribution networks. This problem is addressed in this paper by a well-designed converter that maintains a constant output voltage.</span>

“…In that sense, a great number of MPPT techniques have been introduced, discussed, and tested, such as perturb and observe (P&O) [ 10 , 11 , 12 ], resistance perturbation and observation (RP&O) [ 13 ], incremental conductance (IC) [ 14 , 15 , 16 , 17 ], the beta method [ 18 ], ripple correlation [ 19 , 20 ], systems oscillation [ 21 , 22 ], MPP locus characterization [ 23 ], reinforcement learning [ 24 ], sliding mode [ 25 ], and compensator-based methods [ 7 , 26 ]. Among these approaches, the P&O and IC based on the PI MPPT algorithms demand special attention because they offer outstanding performance and high speeds during initialization procedures [ 7 , 26 ].…”

This paper presents novel current sensorless maximum-power point-tracking (MPPT) algorithms based on compensators/controllers and a single-input voltage sensor. The proposed MPPTs eliminate the expensive and noisy current sensor, which can significantly reduce the system cost and retain the advantages of the widely used MPPT algorithms, such as Incremental Conductance (IC) and Perturb and Observe (P&O) algorithms. Additionally, it is verified that the proposed algorithms, especially the proposed Current Sensorless V based on PI, can reach outstanding tracking factors (TFs) such as the IC and P&O based on PI algorithms. In this sense, the insertion of controllers inside the MPPT gives them adaptive characteristics, and the experimental TFs are in the remarkable range of more than 99%, with an average yield of 99.51% and a peak of 99.80%.
