ABSTRACT
This study presents a new kind of maximum power point tracking algorithm based on perturb and observe algorithm and incremental conductance algorithm compare. A generalized photovoltaic array simulation model in MATLAB/Simulink environment is developed and presented. This paper presents in details comparative study between two most popular algorithms technique which is incremental conductance algorithm and perturb & observe algorithm. Considering the effect of solar irradiance and temperature changes, the output current and voltage of PV modules are simulated and optimized using this model. Cuk converter use for comparative study. Few comparisons such as efficiency, voltage, current and power output for each different combination has been recorded in this paper. Cuk converters are considered as possible dc–dc converters that can be cascaded. MATLAB simulations are used to compare the efficiency of each topology as well as evaluating the benefits of increasing cost and complexity. The cuk converters are shown to be the most efficient topologies for a given cost, with the cuk best suited for long strings. The proposed model is designed with a user-friendly icon and a dialog box like Simulink block libraries.
