A popular method used to maximize the power output of solar panels is Maximum Power Point Tracking (MPPT). This work attempted to improve MPPT by utilizing an artificial neural network (ANN) algorithm and gradient perturbation of the duty cycle, dubbed the Neural-Gradient MPPT method. The ANN takes in as input, irradiance, and temperature, whereas its outputs are the power and current at the MPP. We compared our proposed algorithm to the popular traditional MPPT algorithm, perturb and observe (P&O). Our proposed MPPT technique has a faster response to abrupt changes in solar irradiance and temperature and less steady-state error than the baseline P&O algorithm. © 2023 IEEE.

There are not many studies conducted in the implementation of maximum power point tracking (MPPT) methods for heaving wave energy converters (WECs). An assessment of damping control using various MPPT methods for heaving WEC was conducted in this study. Damping control was implemented using a DC-DC boost converter. The duty cycle for MPPT was determined using a perturb and observe algorithm. This assessment study determines the following for applying MPPT for heaving WECs: best location for the observing parameters;best performance index for the MPPT;and effect of averaging the performance index. Three locations for the observing parameters (mechanical parameters near the source, electrical parameters at the load, and electrical parameters between the source and load) and three performance indices (maximising power, minimising impedance, and maximising admittance) were assessed and evaluated. Finally, the effects of applying the running mean and conventional instantaneous value on the performance index were compared. Various scenarios using nine MPPT methods were tested using simulated regular and irregular sea states. The test results were validated experimentally using a simple and low-cost hardware-in-the-loop (HIL) scheme. The HIL scheme was developed using off-the-shelf devices that can be used for any topology of WECs. The results showed that the MPPT method has an optimum performance by using the performance index for maximising power, using observing parameters between the source and the load, and deploying conventional instantaneous values for the observing parameters.

Maximum power point tracking (MPPT) algorithms are invariably employed to utilize solar photovoltaic (PV) systems effectively. perturbation based MPPT algorithms are popular due to their simplicity and reasonable efficiency. While novel MPPT algorithms claim increased energy utilization over classic perturbation techniques, their performance is governed by the choice of optimal algorithm parameters. Existing guidelines for parameter optimization are mathematically laborious and are not generic. Hence, this paper aims to provide simple and comprehensive guidelines to ensure optimal performance from the perturbation based MPPT technique. For an illustration of proposed claims, a solar PV fed boost converter is investigated to examine the effect of input capacitor, digital filter cut-off frequency, system time constant and sampling time on implementing a classic perturb and observe (P and O) algorithm. The readers will be presented with two simple step tests (to determine the effective system time constant) and proposed guidelines to choose the optimal performance sampling time. Necessary laboratory experiments show that an appropriate choice of sampling time could increase efficiency and ensure system stability. This investigation's learnings can be easily extended to any power electronics converter, loads and all perturbation-based algorithms used in solar PV systems. The results of appropriate tests on the system's mathematical model and the laboratory prototype are presented in detail to support this research's claims.

Reactive control is a popular method for maximizing wave energy absorption in wave energy converters (WECs). This technique involves adjusting the damping and stiffness coefficients of the WEC to align its natural frequency with the frequency of incoming waves. Unfortunately, wave variability and complex hydrodynamics have posed challenges in accurately determining these coefficients. This paper proposes a model-independent approach for reactive control based on a variable step size maximum power point tracking (MPPT) algorithm. The MPPT algorithm tunes the WEC's damping and stiffness coefficients toward maximum generated power. Furthermore, a power curtailment control (PCC) strategy is integrated, based on a proportional-integral (PI) controller that modifies the MPPT control force to follow power generation references below its maximum generation capacity. This capability is essential for grid integration, where power generation must match demand. Finally, a hardware-in-the-loop experimental setup was constructed to evaluate the proposed control strategies under monochromatic and polychromatic wave conditions. An analysis comparing MPPT and damping control under various polychromatic wave conditions revealed that MPPT achieves substantially higher electrical power, outperforming damping control by 55.4% to 70.6%. The experimental results demonstrated the efficacy of the PCC strategy in reducing the WEC power output to track specific power setpoints.

This article proposes a standalone hybrid wind-photovoltaic (PV) water pumping system (WPS) with minimal power electronics interface, simple composite control, and optimal energy management strategy (EMS) for effective utilization of both renewable sources. The proposed system consists of classic perturb and observe (P&O) algorithm applied to the boost converter of the solar PV system and voltage regulation algorithm/hill-climbing MPPT algorithm with zero steady-state oscillation (ZSSO) applied to bidirectional voltage source converter (VSC) of wind energy conversion systems (WECS) for optimal power extraction at all times. The constant voltage to frequency (V/F) ratio is ensured at the point of common coupling (PCC) for the entire operating range to avoid saturation in the self-excited induction generator (SEIG) and the induction motor (IM) pump. The energy management strategy is devised to effectively harness renewable energy from both sources while ensuring the DC-link voltage stability. The system forms compelling proposition, given the least converter count to integrate solar-PV and wind energy employing easy to implement control algorithms with optimal energy extraction. The results of simulation and experimental studies on the proposed system reveal the effectiveness of the composite controller in terms of energy utilization, constant flux operation, and power balance for the entire operating range. Additionally, system exhibits acceptable dynamic and steady-state behavior against variations in wind velocity, solar irradiation, and load.

In this paper, we design a DC/DC converter with maximum power point tracking (MPPT) function for harvesting maximum output energy from the automotive exhaust thermoelectric generator (AETEG) regardless of the engine operating conditions and values of the connected electrical load. Our developed AETEG has a multi-section structure. Due to non-uniform temperature distribution over the surface of the AETEG each section has its own temperature difference. Application of MPPT devices for such types of thermoelectric generators is accompanied by certain difficulties. Different thermal conditions of each section may cause effectivity losses of MPPT device application. Experiments are conducted with a real car engine and AETEG in order to identify the most suitable connection type between AETEG sections and MPPT device.

This paper focuses on wireless power transfer based on Witricity technology, specifically wireless battery charger application for electric vehicle. In order to reach efficient power transfer, a principle of coupling magnetic resonance at high frequency is used. However, in high range frequency, several losses may offer such as peak power, switching losses as well as reducing the size of the required battery capacity. In order to avoid the battery's damage, perturb and observe maximum power point tracking algorithm connected with photovoltaic panel is performed. The main objective of this contribution based on proposing a self-correction algorithm to adjust misalignment between primary and secondary coils caused by a random parking of the electric vehicle and to produce suitable input power battery at important frequency level.

In the last decade, the use of renewable energy resources instead of fossil fuels pollutants has increased exponentially. Photovoltaic energy generation is ever more important as a renewable resource since it does not cause in fuel costs, pollution, maintenance, and emitting noise compared to other renewable resources as more accessibility of solar irradiation. In this paper, The Maximum Power Point Tracking (MPPT) controller for boost converter based on perturb and observe control is developed and compared to conventional tracking algorithm Incremental Conductance. The different steps of the design of these controllers are presented together with its simulation. The whole system is simulated under standard climatic conditions (1000 W/m2, 250C) in MATLAB and the irradiance is varied from 600 W/m2 to 900 W/m2. Results of this simulation shown that the system with MPPT using P&O controller increase the efficiency of energy production from PV.

To extract maximum output from a solar photovoltaic (PV) array, various maximum power point tracking (MPPT) algorithms have been proposed in the literature. Among all the MPPT algorithms, perturb and observe (P&O) algorithm is most commonly used because it is simple and easy to implement. But, the conventional P&O algorithm has some limitations. It has poor efficiency at steady state as the operating point oscillates around the maximum power point (MPP) and it shows poor dynamic response if a sudden change in atmospheric condition takes place. Also, for single phase Grid connected PV system, dc-link voltage contains a second harmonic ripple. This voltage ripple causes steady state oscillations in PV voltage. To overcome all these limitations, a modified P& O algorithm has been proposed in this paper. It shows improved steady state response and dynamic response during any change in atmospheric condition. The performance of the proposed scheme is verified using MATLAB/SIMULINK based environment.
