In this paper, the application of an Adaptive Network-based Fuzzy Inference System (ANFIS) to control a hybrid solar and wind grid-tie inverter in order to reduce power oscillations and enhance power quality is presented. To extract the maximum power from the PV system, a Perturb and Observe (P&O) algorithm is presented that tracks the Maximum Power Point (MPP). Time-domain simulation results of the studied system are performed in MATLAB/SIMULINK under different operating conditions such as changing irradiation and short-circuit faults in the power grid. From the simulation results, it can be concluded that the designed ANFIS controller and the proposed P&O algorithm perform better than the traditional PI controller and improve transient responses under severe operating conditions.

Power Point

The maximum output power of a photovoltaic (PV) system with a DC-DC converter depends mainly on the solar irradiance (G) and the temperature (T). Therefore, a maximum power point tracking (MPPT) mechanism is required to improve the overall system. The conventional MPPT approaches such as the perturbation and observation (P&O) technique have difficulty in finding true maximum power point. Thus various intelligent MPPT systems such as fuzzy logic controllers (FLC) are recently introduced. In FLC based MPPT, selecting the type of the membership function (MF) and the number of the fuzzy sets (FS) is critical for better performance. Thus, in this paper various adaptive neuro fuzzy inference system (ANFIS) is utilized to automatically tune the FLC membership functions instead of adopting the trial and error method. To find suitable MF for FLC, ANFIS is developed in MATLAB/Simulink and the effect of different types MF investigated. Simulation result shows that the FLC with triangular MF and seven FS give the best result. The evaluation indices used in this study includes the maximum extracted energy, minimum standard deviation of the error, and minimum mean square error.

This paper presents a method of intelligent control of a photovoltaic generator (PVG) connected to a load and a battery. The system consists of charging and discharging a battery. An intelligent algorithm based on adaptive neuro-fuzzy inference system (ANFIS) is presented in this work. It performs two separate tasks simultaneously. First, it is used as a PVG Maximum Power Point Tracking (MPPT) command. This same algorithm is used secondly for protecting the battery against deep charges and discharges. A regulation of the DC bus voltage is also carried out by means of a PI corrector for a good supply of the load. The simulation results under MATLAB/Simulink show that the method proposed in this work allows the PV system to function normally by charging and discharging the battery whatever the weather conditions.

Photovoltaic (PV) energy is one of the most important energy sources since it is clean and inexhaustible. It is important to operate PV energy conversion systems in the maximum power point (MPP) to maximize the output energy of PV arrays. An MPPT control is necessary to extract maximum power from the PV arrays. In recent years, a large number of techniques have been proposed for tracking the maximum power point. This paper presents a comparison of different MPPT methods and proposes one which used a power estimator and also analyses their suitability for systems which experience a wide range of operating conditions. The classic analysed methods, the incremental conductance (IncCond), perturbation and observation (P&O), ripple correlation (RC) algorithms, are suitable and practical. Simulation results of a single phase NPC grid connected PV system operating with the aforementioned methods are presented to confirm effectiveness of the scheme and algorithms. Simulation results verify the correct operation of the different MPPT and the proposed algorithm.

The maximum power point tracking (MPPT) algorithms ensure optimal operation of a photovoltaic (PV) system to extract the maximum PV power, regardless of the climatic conditions. This paper exposes the study, design, simulation and implementation of a modified advanced neural fuzzy inference system (ANFIS) MPPT algorithm based on fuzzy data for a PV system. The studied system includes a PV array, a DC/DC buck converter, the ANFIS controller, a proportional-integral (PI) controller, and a load. The simulation and experimental tests are carried out with the MATLAB/Simulink software and LabVIEW, respectively. Moreover, the obtained results are compared with previously published results by incremental conductance (IC) and fuzzy logic (FL) algorithms under different climatic conditions of irradiation and temperature. The results show that the proposed ANFIS algorithm is able to track the maximum power point for varying climatic conditions. Furthermore, the comparison analysis reveals that the PV system using ANFIS algorithm has more efficient and better dynamic response than FL and IC.

Saat ini bahan bakar fosil berupa minyak bumi dan batu-bara masih menjadi sumber energi yang paling banyak digunakan dalam proses pembangkitan tenaga listrik. Bahan bakar fosil tersebut tidak dapat diperbarui dan jumlahnya semakin menipis seiring dengan berjalannya waktu. Karena kebutuhan energi listrik semakin hari semakin meningkat, sumber energi alternatif terutama sumber energi terbarukan menjadi semakin dibutuhkan. (Sankarganesh, R. & Thangvel).Salah satu sumber energi terbarukan adalah Photovoltaic (PV) yang memanfaatkan energi cahaya matahari. Sumber energi ini memiliki kelebihan yaitu bersih dan tersedia di alam dalam jumlah yang melimpah (Soedibyo, Priananda, C. W. & Haikal, M. A).Sejak ditemukannya PV, teknologi ini terus berkembang hingga saat ini telah ditemukan beberapa jenis sel surya. Pada tahun 1991, seorang ilmuan asal Swis, Michael Gratzel menemukan salah satu jenis sel surya yang memanfaatkan kandungan organik tumbuhan. Temuannya tersebut dikenal dengan Dye Sensitized Solar Cell (DSSC). Prinsip kerja DSSC adalah memanfaatkan eksitasi elektron oleh foton pada cahaya matahari yang mengenai bagian sensitif dari tumbuhan yang disebut dengan dye (O’regan dan Gratzel).Permasalahan dalam penggunaan PV, tak terkecuali jenis DSSC saat ini adalah efisiensinya yang masih rendah dengan biaya yang tinggi. Kebutuhan penggunaan PV yang semakin meningkat mendorong berbagai penelitian mengenai peningkatan efisiensi pada sistem PV. Terdapat tiga faktor yang mempengaruhi efisiensi sistem PV. Pertama adalah material PV. Kedua adalah efisiensi konverter dan efisiensi algoritma Maximum Power Point Tracking (MPPT) (Devi, M. L. & Chilambarasan, M).Adaptive Neuro Fuzzy Inference System (ANFIS) merupakan metode yang menggunakan jaring syaraf tiruan (Neural Network) untuk mengimplementasikan Fuzzy Inference System (FIS) atau sistem inferensi fuzzy. Keunggulan sistem inferensi fuzzy adalah dapat menerjemahkan pengetahuan dari pakar dalam bentuk aturan-aturan, namun biasanya dibutuhkan waktu yang lama untuk menetapkan fungsi keanggotaannya. Oleh sebab itu dibutuhkan teknik pembelajaran dari jaringan syaraf tiruan untuk mengotomatisasi proses tersebut sehingga dapat mengurangi waktu pencarian, hal tersebut menyebabkan metode ANFIS sangat baik untuk diterapkan pada MPPT (Tarek, B., Said, D., & Benbouzid, M.E.H).Penelitian ini mengoptimalkan sistem photovoltaic menggunakan DSSC untuk sisi material, Cuk converter untuk sisi converter dan metode ANFIS sebagai MPPT (Maximum Power Point Tracking) yang mengontrol Cuk converter untuk aplikasi sistem PV.

Purpose The solar photovoltaic (PV) system is one of the outstanding, clean and green energy options available for electrical power generation. The varying meteorological operating conditions impose various challenges in extracting maximum available power from the solar PV system. The drawbacks of conventional and evolutionary algorithms-based maximum power point tracking (MPPT) approaches are its inability to extract maximum power during partial shading conditions and quickly changing irradiations. Hence, the purpose of this paper is to propose a modified elephant herding optimization (MEHO) based MPPT approach to track global maximum power point (GMPP) proficiently during dynamic and steady state operations within less time. Design/methodology/approach A MEHO-based MPPT approach is proposed in this paper by incorporating Gaussian mutation (GM) in the original elephant herding optimization (EHO) to enhance the optimizing capability of determining the optimal value of DC–DC converter’s duty cycle (D) to operate at GMPP. Findings The effectiveness of the proposed system is compared with EHO based MPPT, Firefly Algorithm (FA) MPPT and particle swarm optimization (PSO) MPPT during uniform irradiation condition (UIC) and partial shading situation (PSS) using simulation results. An experimental setup has been designed and implemented. Simulation results obtained are validated through experimental results which prove the viability of the proposed technique for an efficient green energy solution. Originality/value With the proposed MEHO MPPT, it has been noted that the settling period is lowered by 3.1 times in comparison of FA MPPT, 1.86 times when compared to PSO based MPPT and 1.29 times when compared to EHO based MPPT with augmented efficiency of 99.27%.

Abstract Maximum Power Point Tracking (MPPT) is now widely used method in increasing the photovoltaic (PV) efficiency. The conventional MPPT methods have many problems concerning the accuracy, flexibility and efficiency. The MPP depends on the PV temperature and solar irradiation that randomly varied. In this paper an artificial intelligence based controller is presented through implementing of an Adaptive Neuro-Fuzzy Inference System (ANFIS) to obtain maximum power from PV. The ANFIS inputs are the temperature and cell current, and the output is optimal voltage at maximum power. During operation the trained ANFIS senses the PV current using suitable sensor and also senses the temperature to determine the optimal operating voltage that corresponds to the current at MPP. This voltage is used to control the boost converter duty cycle. The MATLAB simulation results shows the effectiveness of the ANFIS with sensing the PV current in obtaining the MPPT from the PV.
