Performance Comparison of FLC MPPT with P & O and Incremental Conductance MPPT For standalone PV System

Solar energy is one of the most important renewable energy sources. Photovoltaic power is one of the main ways of solar energy utilization, has the characteristics of environmentally-friendly and non-polluting, application range is very wide, has now been used in communication, transportation and other fields, has a place in the national economy energy system. However, the use of the solar energy is deeply influenced by the terrain, topography, position, weather and any other natural conditions, and has the problem about intermittence, sunlight direction and intensity changing along with the time, so it requires a higher request of collecting and using solar energy. In this paper, Fuzzy Logic Control (FLC)based MPPT is adopted for extraction of maximum power from PV panel and its performance is compared with P & O and InC algorithm for tracking a MPP on the V-I characteristic of the solar PV panel. The simulation results can be validated the effectiveness of the proposed work under various atmospheric conditions using Matlab Simulink software.
