This paper discusses the performance
improvement of photovoltaic water pumping system using both
P&O and IC MPPT controllers. The efficiency of both
proposed MPPT controller has been studied successfully using
a DC motor-pump powered by thirty six PV modules fed by
DC-DC boost converter controlled using both P&O as well as
IC MPPT algorithms. Comparative study results obtained
using Matlab/Simulink environment show that the IC
outperforms the P&O method in term of convergence speed;
while the P&O method presents better performance for the
steady state oscillation in case of high level insolation. In case of
low level insolation (point C), the steady state oscillations
around the MPP point are less in IC compared to those in P&O
algorithm.
