Design, optimization and realization of a photovoltaic system to the operation of the photovoltaic station realized in Douar Zragta of the rural Oujda Angad Prefecture

摘要

In this paper, we present the results related to the design, realization and modeling of a photovoltaic (PV) prototype with a powerful analogical command MPPT (Maximum Power Point Tracking). The results will be validated on the ground in the case of a PV station, for lighting and pumping water. These works are realized in the framework of ‘Art Gold Morocco’ Program of the United Nations (UN) to improve the living conditions of the inhabitants of Douar Zragta (Rural District of Oujda-Angad Prefecture). This Douar is not connected to the electrical network of ONE and does not have access to drinking water provided by ONEP. The results obtained show that the prototype developed in our research team reduces significantly the energy losses produced by PV panels (<7%). Electrical characterization and modeling results carried out at the PV station of Douar Zragta, compared to those obtained in our laboratory, allowed us to conclude that the electrical power losses of the station are about 25–30%. Therefore, the use of the prototype developed in our team is necessary to improve the energy performance and reduce the cost of the PV station.
