摘　　要：The present study is a contribution to the study of hybrid electric power conversion systems in rural areas.The approach adopted uses a methodology for analyzing the complementarity that exists between the two renewable energy potentials(solar and hydraulic)based on their daily,monthly and annual variations.The different analytical formulas for sizing a PV(photovoltaic)field and a small hydroelectric power station are recalled in this work.The HOMER software served as a tool for optimal sizing and simulation of the system.This work focuses on the analysis of the behavior and control of the performances of a hybrid system made up of two renewable energy sources,hydroelectricity/PV with a storage system and a converter.The main results obtained relate to:monitoring of the variation in temperature variation,solar irradiation of the site,as well as the flow of the watercourse.The profile of the village’s annual charges is known.The annual production of electrical energy is 527.936 kWh/year.The hydroelectric plant will provide 155.316 kWh/year,or 29%,and for the PV field(372.620 kWh/year),or 71%.The monthly energy average is 43.995 kWh/month.The average daily consumption is 731 kWh/d with a maximum power of 163 kW.The completion of this project makes it possible to cover all electrical loads in the Tamagaly district,with an annual energy production of 206.783 kWh.This would make it possible to locally limit greenhouse gas emissions in the area.
