Introduction:
This
PROJECT deals with the design and simulation of a simple but efficient
photovoltaic Water pumping system. It provides theoretical studies of photovoltaic’s
and modeling Techniques using equivalent electric circuits. The system employs
the maximum power point Tracker (MPPT). The investigation includes discussion
of various MPPT algorithms and Control methods. PSpice simulations verify the
DC-DC converter design. MATLAB Simulations perform comparative tests of two
popular MPPT algorithms using actual Irradiance data. The thesis decides on the
output sensing direct control method because it requires fewer sensors. This
allows a lower cost system. Each subsystem is modeled in Order to simulate the
whole system in MATLAB. It employs SIMULINK to model a DC Pump motor, and the
model is transferred into MATLAB. Then, MATLAB simulations verify the system
and functionality of MPPT. Simulations also make comparisons with the System without
MPPT in terms of total energy produced and total volume of water pumped per
day. The results validate that MPPT can significantly increase the efficiency
and the performance of PV water pumping system compared to the system without
MPPT.
