Improved Model

In this paper, an improved model of photovoltaic cell is proposed. By using Lambert W function, the improved model of solar cell is deduced. Meanwhile, the current-voltage and power-voltage curves of photovoltaic cell are calculated and simulated in Matlab/Simulink environment. Compared to the popular model and experimental data, the proposed method shows excellent agreement between the current-voltage points. It is found that the proposed modeling method has less error at the maximum power point state.

Energi matahari merupakan energi terbarukan yang dapat dimanfaatkan untuk menghasilkan energi listrik. Sedangkan yang dapat mengkonversi energi cahaya matahari menjadi energi listrik adalah photovoltaic cell. Akan tetapi dalam proses pengkonversian energi cahaya ini ada kendala yang dipengaruhi beberapa faktor sehingga mengurangi optimalisasi sistem kerja photovoltaic cell. Salah satu faktor utama yang mempengaruhi optimalisasi sistem photovoltaic adalah radiasi sinar matahari yang berubah–ubah sehingga tidak maksimalnya sinar cahaya yang didapat. Dengan melihat permasalahan tersebut maka diperlukan alat penjejak matahari agar solar cell selalu tegak lurus menghadap matahari. Sistem ini menggunakan sensor cahaya (LDR) dan keluaran berupa arus DC. Dengan aturan yang disesuaikan dengan kondisi, maka motor DC akan menggerakkan solar cell supaya bergerak mengikuti posisi matahari secara otmatis. Paper ini menyajikan analisa dan desain untuk penjejak Maximum Power Point Tracker (MPPT) dengan menggunakan Metode Fuzzy Logic (MFL). Dalam penghitungan pengendali penjejak orientasi matahari ini digunakan sistem Metode Fuzzy Logic (MFL) karena metode ini merupakan kontrol pada proses tahapan himpunan, proses fuzzyfikasi, aturan fuzzy, dan proses defuzzyfikasi dan karena metode ini sangat cocok untuk pengembangan produk selanjutnya. Penelitian ini menggunakan ATMega8 yang mudah dipasang pada penggunaan solar cell mandiri maupun yang berskala besar.

In photovoltaic (PV) system, maximum power tracking (MPPT) is crucial to improve the system performance. Irradiance and temperature are the two important parameters that affect MPPT. The conventional perturbation and observation (P&O) based MPPT algorithm does not accurately track the PV maximum power point. Therefore, this paper presents an improved P&O algorithm (Im-P&O) based on variable perturbation. The idea behind the Im-P&O algorithm is to produce variable step changes in the reference current/voltage for fast tracking of the PV maximum power point. The Im-P&O based MPPT is designed for the 25 SolarTIFSTF-120P6 PV panels, with a capacity of 3 kW peak. A complete PV system is modeled using the MATLAB/Simulink. Simulation results showed that the Im-P&O based MPPT achieved faster and accurate performance compared with the conventional P&O algorithm.
