Fuzzy based MPPT technique for photovoltaic system with boost and super-lift boost converters [articol]

Abstract

In present scenario, deficiency of power generation due to lack of fossil fuel and lack of cost-effectiveness in rural areas has become a challenge. One of the solutions is to rely on renewable energy such as solar energy to generate electricity. Accordingly, the efficiency of the photovoltaic (PV) system can be optimized by implementing the fuzzy-logic based Maximize Power Point Tracking (MPPT) algorithm. In this work presents the simulation results of the fuzzy logic control based MPPT by using MATLAB/SIMULINK for 55W capacity of Boost and Super-Lift Boost Converters (SLBC).The evaluated performance of the converters with different irradiance applied in photovoltaic system are presented based on the parameters current, voltage and power in detail. The performance of both converters are analysed and compared. The tracking speed of FLC-based MPPT is superior to that of the conventional MPPT method. It is clearly observed that the proposed SLBC is more suitable for Photo voltaic application.
