Comparative Study MPPT between FLC and Incremental Conductance Applied on PV Water Pumping System

Photovoltaic water pumping application is important field of interest for sustainable development. The maximum power point (MPP) at which PV system is to be operated is tracked by peak tracker to utilize solar power. Performance of any MPPT can be evaluated based on tracking speed, accuracy and stability. This paper deals with the application of the incremental conductance and fuzzy logic controller to extract the maximum power point in a PV water system with field oriented control of a permanent magnet synchronous motor (PMSM). The proposed MPPT techniques were developed and tested successfully on the PV water pumping system. A comparative study between the proposed methods under similar operating conditions is presented. The performances in terms of voltage and power ripples show the effectiveness of the fuzzy logic MPPT technique.
