Description: Solar photovoltaic (SPV) water pumping systems have the potential to provide clean drinking
water to millions of unserved people around the world. The abundant solar energy resource and groundwater
availability in the Pacific Island Countries (PICs) can be combined to make much needed potable water avail
able to remote island communities in these countries. This paper looks at the feasibility of using a SPV pump

Description: Abstract—In this paper a single-stage solar PhotoVoltaic (PV)
system feeding the power to an Open-End Winding Induction
Motor (OEWIM) via a dual-inverter is presented. The OEWIM is
coupled to a centrifugal pump for water pumping application.
The dual-inverter fed OEWIM is chosen, as it requires low dcbus
voltage which helps in optimal arrangement of PV modules,
which could avoid large strings. Platform: |

Description: The use of solar energy as a source for pumping water is one of the promising areas in the photovoltaic (PV) application. The energy of photovoltaic pumping systems (PVPS) can be widely improved by employing an MPPT algorithm. This will lead consequently to maximize the electrical motor speed of the system. This paper presents a modified incremental conductance (IncCond) MPPT algorithm with direct control method applied to a standalone PV pumping system. The influence of the algorithm parameters on system behavior is investigated and compared with the traditional (INC) method. The studied system consists of a PV panel, a DC-DC boost converter, and a PMDC motor-pump. The simulation of the system by MATLAB-SIMULINK is carried out. Simulation results found are satisfactory.-The use of solar energy as a source for pumping water is one of the promising areas in the photovoltaic (PV) application.

tracking (MPPT) algorithm is required to improve the energy
utilization efficiency of low power photovoltaic (PV) systems. This
paper presents an experimental uation of the incremental
conductance MPPT algorithm when employed by a standalone
PV pumping system, using an experimental installation comprised
of a 1080-Wp photovoltaic array connected to a 1-kW permanent
magnet dc motor-centrifugal pump set. Particular focus is given
to the uation of the two commonly utilized implementation
techniques: reference voltage perturbation and direct duty ratio
perturbation. The influence of algorithm parameters on system
behavior is investigated and the energy utilization efficiency is
calculated for different weather conditions. The performance of
the incremental conductance algorithm is compared to that of

Description: In recent years, the application of photovoltaic system has been increasingly popular, especially in remote areas, where power is not available or is too expensive to install. However, the PV generator’s cost is relatively high and has nonlinear dependent-irradiation volt-ampere characteristics which make it difficult to control if we need to obtain maximum power. In this paper, the operation of a PV system which comprises a PV generator, a buck converter and a DC motor-pump is thoroughly examined. The buck converter controls the solar array operating point in order to track maximum power point (MPP) by using a non linear control strategy based on feedback linearization. This technique is shown to be able to obtain a linear control of the PV system and can dramatically increase its dynamical performance Platform: |
