This paper proposes an efficient and fast maximum power point tracking (mppt) algorithm for a wind turbine (WT) connected to a battery bank via a permanent magnet synchronous generator, a three-phase diode rectifier, and a dc-dc boost converter. The algorithm is based on the Takagi-Sugeno (TS) fuzzy system and optimal relation methods and is called TS-mppt. The fuzzy system computes the converter duty cycle using an input that combines the error and its rate of change. The error is the difference between the reference current computed from the optimal relation and the rectifier current. The methods used in the algorithm resulted in a five-rule TS fuzzy system, which contributed to a fast algorithm in terms of its total execution time (TET): 89.12 s on the F28069M board. The TET attained enabled a synchronized operation of the algorithm with the converter switching frequency. Additionally, the results based on the processor-in-the-loop simulation approach show that the TS-mppt algorithm achieves an effective MPP tracking process with an energy conversion efficiency of 99.43% and behaves properly when evaluated over the typical WT power curve. Furthermore, the effectiveness and performance of the proposed algorithm are demonstrated against others using the proportional-integral controller, the Mamdani fuzzy method, and a TS fuzzy model from the literature.

Photovoltaic (PV) panels are widely used in the generation of electricity from solar radiation. To improve the efficiency of PV energy generation systems, the PV panels should operate at around the maximum power point (MPP), which can be provided by maximum power point tracking (mppt) algorithms. In the present study, we designed a novel mppt algorithm that has less complexity and low computation load than existing traditional mppt algorithms and that starts to track near the MPP. The proposed algorithm takes extraterrestrial irradiances into account when defining operation points close to MPP. The MPP parameters were computed using datasheet information of the PV panel to achieve a low computation load. The proposed algorithm was tested for efficiency and performance under different scenarios, including partial shade conditions, against the Perturb & Observe (P&O) algorithm. The test results showed that the proposed algorithm outperformed the P&O algorithm.

With the gradual popularization of shared vehicles, the large-scale access of electric vehicle charging pile will have a significant impact on the operation planning of power grid. Therefore, a vehicle charging control strategy based on the Internet of things is proposed. Combined with the basic principle of mppt algorithm and fully considering the actual needs, the peak load of the charging pile is adjusted from the load limit, and the voltage energy consumption of the charging circuit is accurately controlled to realize the intelligent charging of the shared vehicle. The test results show that, compared with other methods, the peak load of the line in this paper is smaller and the load curve is smoother, which is conducive to the safe and stable operation of the power grid;it can effectively reduce the loss rate, which is conducive to the economic operation of the power grid, improve the voltage quality, and ensure the power demand of users.

A single-input bipolar converter has been proposed along with a fast mppt tracking algorithm. The proposed converter is used as an interface for PV panel to perform twofold task of effectively extracting the maximum power from the PV side and efficiently delivering the extracted power to the load. For effectively tracking the MPP (maximum power point) of PV panel, a modified perturb and observe (MP&O) algorithm has been proposed in the paper. Proposed algorithm works effectively even under fast variations of irradiation and ambient temperature. The proposed converter has been developed with a target application in DC nanogrid by providing two loading points with amplitude balanced bipolar outputs. Moreover, least input current ripple (compared with other conventional DC-DC converters) aids the MPP algorithm in improving the tracking efficacy. As the proposed converter has synchronous switching operation at both output terminals referred to input side, the power conversion efficiency of the converter is very high. Two out of three switches used are ground referenced;thus, design complexity of the converter is greatly reduced. Proposed converter with the MP&O algorithm has been analyzed, and the simulation results are obtained using MATLAB/Simulink. A laboratory developed prototype is used to experimentally validate the proposed converter.

In order to operate a solar photovoltaic (PV) system at its maximum power point (MPP) under numerous weather conditions, it is necessary to achieve uninterrupted optimal power production and to minimize energy losses, energy generation cost, and payback time. Under partial shading conditions (PSC), the formation of multiple peaks in the power voltage characteristic curve of a PV cell puzzles conventional MPP tracking (mppt) algorithms trying to identify the global MPP (GMPP). Meanwhile, soft-computing mppt algorithms can identify the GMPP even under PSC. Drawbacks such as structural complexity, computational complexity, huge memory requirements, and difficult implementation all affect the viability of soft-computing algorithms. However, those drawbacks have been successfully overcome with a novel ten check algorithm (TCA). To improve the performance of the TCA in terms of mppt speed and efficiency, a novel concept of data arrangement is introduced in this paper. The proposed structure is referred to as Optimized TCA (OTCA). A comparison of the proposed OTCA and classic TCA algorithms was conducted for standard benchmarks. The results proved the superiority of the OTCA algorithm compared to both TCA and flower pollination (FPA) algorithms. The major advantage of OTCA in mppt stems from its speed as compared to TCA and FPA, with almost 86% and 90% improvement, respectively.

The real implementation of the maximum power point tracking (mppt) controllers for the photovoltaic (PV) systems is still a big challenge for researchers working in this field. Often, they use simulation tools to assess the performance of their mppt algorithms before actual implementation. In this context, this paper aims to propose a trusted simulation of a PV system designed under Proteus software. The proposed PV simulator can be used to verify and evaluate the performance of mppt algorithms with a closer approximation to the real implementation. The main advantage of this model that it contains a real microcontroller, as can be found in reality, so that same code for the mppt algorithm used in the simulation will be used in real implementation. In contrast, when using (Powersim Software) PSIM or Matlab/Simulink, the code of the algorithm must be rewritten once the real experiment begins, because these tools don't provide a microcontroller or an electronic board in which our algorithm can be implemented and tested in the same way as the real experiment. After this section, a modified Hill-Climbing (HC) algorithm is introduced. The proposed algorithm can avoid the drift problem posed by conventional HC under a fast variation in insolation. The simulation results show that this method presents good performance in terms of efficiency (99.21%) and response time (10 ms), which improved by 1.2% and 70 ms respectively compared to the conventional HC algorithm.

In this study, a maximum power point tracking (mppt) technique based on parabolic extrapolation has been presented for thermoelectric generator systems. Conventional mppt methods require a closed-loop controller and perturb and observe (P&O) method to provide fast-tracking response. However, they produce power loss due to small oscillations in the steady state. The proposed method excludes the use of closed-loop controller and steady-state oscillations by directly estimating the coordinates of MPP using three random operating points on the parabolic P-I curve. To substantiate the effectiveness of the parabolic extrapolation-based mppt algorithm, different conditions of temperature gradient and load have been applied. The results demonstrate that the proposed algorithm takes <15% of the time taken by P&O method to track the MPP.

To ensure the photovoltaic (PV) system can still output maximum power under changing environmental conditions, a modified hill climbing algorithm is proposed. The algorithm uses a variable step-size strategy to reduce the steady-state oscillations and prevent operating point from diverging away from the maximum power point by introducing boundary conditions. To verify its effectiveness, the proposed algorithm is compared with the conventional and adaptive hill climbing method under the environmental condition of irradiance step change and gradual change. The simulation results show that the proposed algorithm can increase the dynamic response speed of the PV system by 75% under varying irradiance, and can achieve a steady-state tracking accuracy of 99.8%. Besides, the proposed algorithm only needs to embed several lines of additional programs in the conventional hill climbing maximum power point tracking (mppt) control program and does not require additional hardware components, which reduces the cost of PV power generation.

As the output characteristic of photovoltaic arrays is a non-linear function of external environment, the step-size of maximum power point tracking (mppt) algorithm should be regulated dynamically to improve the mppt efficiency. However, the step-size, essentially determining the performance of mppt algorithm, is often designed for a particular system with certain working conditions. To solve this problem, an optimisation algorithm is proposed in this study, which can adjust the step-size automatically. From the essence of optimisation problem, the tracking process can be converted into a maximum sequence which can be solved by several iteration algorithms. This study provides a simple and effective way to obtain the step-size. Once the iteration method is selected, the performance of the mppt algorithm has been decided. The analysis of convergence, convergence order and stability are presented in this study. Comprehensive simulation and experimental results demonstrate that this proposed algorithm has a good stable and dynamic characteristic.
