In this work, the study gives attention for improvement of the Maximum power point Tracking (MppT) using the perturb and observe (p&o) algorithm based MppT applied to solar power generation system (SpGS). The algorithm components are refined, outcomes of the resultant optimized values are compared to address challenges in optimizing power, voltage and efficiency with the research. Further to improve this performance, Fractional order proportional Integral Derivative (FopID) criteria are tuned using optimization techniques such as Black Hole (BH) optimization, Jaya optimization algorithm (JoA), and Sunflower optimization (SFo). Selection of optimal power and voltage values was aided by these methods. Limitations of the study include the exclusion of dynamic environmental changes in the analysis, and the potential non specificity of optimization algorithms for all SpGS scenarios considered. SpGS offers an opportunity to explore more dynamic models, as well as alternative algorithms, to improve the power and voltage management done in SpGS. © Bharati Vidyapeeth's Institute of Computer Applications and Management 2025.

To maximize power transfer from the pV panel, a perturb and observe (p&o) algorithm and a feedback controller are used to create the Maximum power point Tracking (MppT) algorithm. The dynamic performance of the MppT algorithm depends on the feedback controller's ability to track the pV panel voltage to the reference voltage from the p&o algorithm. This research introduces an adaptive proportional-Integral- Derivative (pID) controller that improves the dynamic characteristics of the MppT algorithm. The proposed adaptive control technique utilizes a pID controller and the exponential forgetting recursive least squares (EFRLS) algorithm to update the pID gains online. The verification process involves simulations under three scenarios: slow and fast variations in temperature, solar insolation, resistive load, and partial shading situations. The proposed adaptive pID controller performs robustly during tracking pV panel voltage under different atmospheric conditions.

The most significant challenge the maximum power point tracking (MppT) algorithms face is reaching the global MppT under partial shading conditions (pSC). In this case, the power-voltage (p-V) and current-voltage (I-V) characteristic curves of the photovoltaic (pV) system produce many maximum power points, which is the reason that the algorithms often trapped in local maximum power point (LMpp). The perturbation and observation (p&o) algorithm is simple and effective for finding Mpp on a mono-extreme graph. Under pSC with many extremes, it is necessary to limit the range of potential GMpp so that this algorithm can avoid the LMpp trap. This paper introduces a global MppT (GMppT) method based on the combination of modified p&o and simulates the behavior of the I-V curve under pSC. In particular, the starting parameters of the algorithm are adjusted in the potential GMpp region to exploit simplicity and efficiency to increase performance and convergence speed. The proposed method determines the area where the GMpp is potentially found more accurately, and this contribution is crucial for increasing the efficiency of the strings of pV arrays under partial shading conditions. By comparing results with other algorithms, such as Modified p&o, Adaptive Jaya (Ajaya), and Jaya, the proposed algorithm has verified its outstanding advantages in MppT performance and search time under the same test conditions.

This paper represents an electrical modeling of a photovoltaic water pumping system composed of photovoltaic panels. The system reassures electrical energy generation applying a DC buck converter in order to supply a DC motor to pump water. Known for its optimal electrical and physical properties, the super capacitor is integrated into the pV pumping system to allow storing electrical energy and powering the pumping motor at nights and cloudy days. The implementation of the perturbation and observation algorithm in the DC buck converter reassures the system's operation around the maximum power point produced by the photovoltaic panel. Moving from quantity problem to quality problem, several internal and external factors can infect the stability of the pV pumping system and disrupt its operation around nominal point. on account of this, a pole placement technique is proposed in this paper. This technique is advocated not only for its simple processing and rapid execution, but also for being based on the conversion of the electrical model of the pV pumping system into a mathematical model that comprises matrix equations. This energy conversion process allows variations in output values in proportion to the input evolution along with positioning the system's poles in the stable points of the S-plane. The equation of this technique applied to the photovoltaic pumping system is indicated in this paper having its program created in Matlab and installed in pLC S7-200 on account of its ability to monitor the inputs instantaneously and modify the outputs in a way proportional to the installed program. Subsequently, the validation of the robustness of this technique is reassured by the comparison between the simulation in Matlab and the experimental tests carried out in sunny periods having the engine powered by photovoltaic panels, and shaded periods where power supply is reassured by the super capacitor.

A Hybrid p&o and pV Characteristics Simulation Method for GMppT in pV Systems Under partial Shading Conditions

Under uniform operating conditions, the power-voltage (p-V) and current-voltage (I-V) curves of a photovoltaic (pV) system have only one maximum point, which facilitates the operation of maximum power point tracking (MppT) algorithms. In practice, the pV systems often operate under heterogeneous environments due to partial shading conditions (pSCs). The p-V and I-V curves exhibit multiple extremes, and distinguishing between the global maximum power point (GMpp) and local maximum power point (LMpp) is a major challenge for algorithms aiming to improve performance and convergence speed. This paper presents a global maximum power point tracking (GMppT) method based on simulating the behavior of the I-V curve of a pV system under the influence of pSCs. With only one initial parameter selected, the proposed solution quickly determines the LMpps based on the characteristics of the pV type and the shading condition during operation. This work helps to limit the potential GMpp region to reduce the search time and improve efficiency by using a simple algorithm and a small tuning step size. The experimental results demonstrate that the proposed method provides superior MppT performance and significantly reduces search time due to improved GMpp detection accuracy combined with small step sizes.

This paper presents three variable step size p&o algorithms for optimizing the separation efficiency of a coalescing pump/deoiling hydrocyclone produced water treatment system. By continuously adjusting the pumping pressure, and subsequently the coalescing effect, the algorithms are used to minimize the oil concentration downstream the hydrocyclone. Due to the variable step size, the algorithms react rapidly to changes in the upstream produced water characteristics, at the same time as they reduce (or eliminate) steady-state oscillations. Based on both simulation and experimental testing, the study discusses advantages and disadvantages of the algorithms.

A novel maximum power point tracker based on analog and digital control loops

In this paper, a new maximum power point tracking (MppT) system for photovoltaic applications is presented. The proposed system consists of two analog loops, a current and a voltage loop, built around a boost converter and a digital loop for the computation of the maximum power point. The analog loops provide a fast response to sudden changes of irradiance conditions while the digital loop, enhancing the accuracy, allows the implementation of various MppT algorithms and facilitates the integration of additional control and monitoring features. Different existing systems are simulated and compared. A small signal model for the proposed system is developed and a novel compensation method is found. The compensation is designed in such a way that it makes the system independent of the input panel used and also of the load connected at the output. In order to have fast simulation results, a macromodel is developed allowing comparison between different algorithms. Furthermore the "perturb and observe" (p&o) algorithm is improved to obtain a better response for changing irradiance conditions. (C) 2011 Elsevier Ltd. All rights reserved.
