Abstract

A photovoltaic (PV) water pumping system has been modelled using TRNSYS considering
a power supply, a direct current (DC)/alternating current (AC) inverter, an AC induction
motor, a centrifugal pump, a well, a water storage tank, and an overflow protection device. The
model emulates actual pumping head curves, uses numerical methods to determine pumpsystem
working points, and includes a storage tank as a component in the system. It simulates
PV-powered water pumping systems, constant voltage tracking, voltage frequency modulation,
and maximum power point tracking algorithms; variable inverter frequency with variable motor
efficiency, variable inverter frequency with constant motor efficiency, and constant inverter frequency
with variable motor efficiency algorithms. It also has the facility to calculate the accumulated
unused part of thePVenergy owing to thepumpreaching itsmaximumcapacity limit.Model
validation was accomplished by comparing simulated results with both the laboratory measurements and long-termfield data from Jordan; good match and accuracy have been achieved.
