Comparative Simulation Analysis of MPPT Techniques of PV System Based on Variuos Algorithms

Currently, renewable energy sources are a well-liked alternative to traditional electrical energy sources that governments are even planning to increase the quantity of electricity generated from renewable energy sources. The rapid growth of investments in renewable energy has drawn the attention of experts who are working to improve its effectiveness. This really is due to a surge in electrical energy consumption brought on by the quick development of technology, population expansion, and high fuel prices utilized in traditional electrical energy generation. Solar energy has gotten a lot of attention from researchers and scientists because it is the most important source of sustainable energy for electric power generation. However, it has a problem that is exacerbated by two factors: changes in solar irradiation intensity besides temperature, which causes their electrical features_to become non-linear, lowering its efficiency. With respect to efficiency issue solving, the researchers devised a number of methods for tracking the MPP point and harvesting the maximum energy from solar panels under a variety of measuring scenarios. In solar energy systems, MPPT technology is the most extensively employed. In this paper, MPPT technology based on the FLC algorithm developed utilizing MATLAB/Simulink is simulated aimed at a purpose of power maximization plus controlling the DC-DC buck converter duty cycle. Through the simulation results, an efficiency of 97.35% is achieved under standard test conditions and 96.41% under volatile weather conditions which gives the superiority of FLC in performance and efficiency of the FLC algorithm.
