Abstract
This paper presents a technical-economic study of a photovoltaic pumping system using an inverter with a Variable Frequency Drive (VFD) to improve system efficiency. We propose a comparative study between two pumping station projects located in places very close to each other, in order to consider that they are exposed to the same meteorological data. One of the projects has the maximum power tracking technique (MPPT), while the other project does not have this technique. The study will compare the various experimental surveys carried out in the field with modeling results using Matlab Simulink.
Highlights
Morocco has launched several energy efficiency programs aimed at optimizing the energy performance of farms, by developing alternative energies, in particular solar pumping [1]
Some authors [2] deal with the modeling and simulation in the MATLAB environment, of a solar pumping systems (SPS) composed of a photovoltaic generator (PVG), converters, an asynchronous machine and a centrifugal pump
Based on experimental measurements carried out in the field, we propose a comparative study between the real performances of two solar pumping sites located, one from the other, approximately within a radius of 1 km
Summary
Morocco has launched several energy efficiency programs aimed at optimizing the energy performance of farms, by developing alternative energies, in particular solar pumping [1]. Other works [4,5,6] present promising SPPV optimization techniques but remain to be validated in practice In this sense, and based on experimental measurements carried out in the field, we propose a comparative study between the real performances of two solar pumping sites located, one from the other, approximately within a radius of 1 km. The first project uses a low-cost frequency converter, which has undergone some modifications described below, in order to adapt to PV panels This system is devoid of the principle of MPPT. The second project is relatively expensive compared to the first, but it has the advantage of being equipped with the MPPT principle
