PERFORMANCE ANALYSIS OF FIS AND ANFIS BASED MPPT FOR SOLAR PV SYSTEM WITH VARIOUS CONVERTERS TOPOLOGIES

Abstract

As a result of increasing population and advancement in technologies the energy demand is also escalating rapidly, due to this exponential increase we cannot rely on non-renewable energy sources as one of our major energy source and some alternative is to be adopted to meet the energy demand of future generation, non- renewable energy sources and moreover solar energy is one of the reliable source of renewable energy and will be the major source of energy in coming years, but this option or source of energy is still not that much efficient and reliable and hence regular work and research is being performed to improve its performance. This project also works on then performance comparison and improvement of performance accordingly of the whole PV system, in this project two soft computing techniques has been implemented for tracking of maximum power point as it helps to extract the maximum power from panel and use it further.

Along with two MPPT techniques work in the field of converters is also accomplished as PV panel produce very less voltage hence a DC/DC converter is much needed to boost that voltage hence in this project four converters: boost, cuk, SEPIC, zeta has been implemented with the PV system and comparison has been made between then performance and characteristics of these four converters along with two MPPT techniques, beside this PV panel here used is also connected to grid to observe its performance with AC load.

All of the work in this project is completed through simulation work in software MATLAB/SIMULINK and results and waveforms have been recorded accordingly.
