The PV system can supply the maximum power to the load at a particular operating point which is generally called as maximum power point (MPP), at which the entire PV system operates with maximum efficiency and produces its maximum power. Hence, a Maximum power point tracking (MPPT) methods are used to maximize the PV array output power by tracking continuously the maximum power point. The proposed MPPT controller is designed for 10kW solar PV system installed at Cape Institute of Technology. This paper presents the fuzzy logic based MPPT algorithm. A fuzzy logic based MPPT control technique is implemented to generate the optimal voltage from the photovoltaic system by modulating the duty cycle applied to the buck boost dc-dc converter. The proposed algorithm gives a good maximum power operation of the PV system. Simulation results obtained are presented and compared with the conventional P&O controller. Simulation results show the effectiveness of the proposed technique.

Model yang dikembangkan dibangun dari modul PV, konverter buck, dan pengendali MPPT. Kontribusi dari makalah ini adalah pada pemodelan konverter buck yang menggunakan pendekatan model persamaan, tidak dengan pendekatan model rangkaian. Model konverter buck yang dikembangkan ini mengijinkan tegangan input konverter, yaitu tegangan keluaran PV, berubah sesuai dengan perubahan siklus kerja, sehingga pada saat terjadi perubahan lingkungan, titik daya maksimum tetap dapat dicapai. Dari hasil percobaan, model yang dikembangkan menghasilkan sifat yang sama dengan model dengan pendekatan rangkaian. Hasil simulasi menunjukkan bahwa model yang dikembangkan dapat mengikuti titik daya maksimum menggunakan algoritma Perturb dan Observe.

The model consists of PV module, buck converter, and MPPT controller. The contribution of the work is in the modeling of buck converter using equation model approach rather than circuit model one. The buck converter model is developed using equation model that allowing the input voltage of the converter, i.e. output voltage of PV is changed by varying the duty cycle, so that the maximum power point could be tracked when the environmental changes. From the experiment, the developed model comforms with the circuit model provided by MATLAB Simulink Power Simulation. Furher, the simulation results show that the developed model performs well in tracking the maximum power point (MPP) of the PV module using Perturb and Observe (P&O) Algorithm.
