Étude du potentiel des systèmes hybrides de pompage solaire.

Abstract

Renewable energy systems were introduced in remote areas because of their energy self reliance. They found many applications, water pumping being one of them. Monthly energy balance techniques is the commonly used method for sizing the renewable energy systems. The stochastic nature of the energy sources reduce greatly the reliability of these systems. To remedy this problem, the systems are usually oversized. Complementary behaviour in time has been observed in many occasions between different types of renewable energy. It is possible to take advantage of this by combining them into hybrid systems. With the help of a simulation software the behaviour of such hybrid pumping water systems was investigated. Photovoltaic systems, wind energy systems, and rain water catchment systems were studied. Combining these technologies into hybrid systems has been shown to be an efficient way to reduce the cost of water pumping systems for certain remote areas. Using the simulation software as opposed to the conventional methods to design these systems has resulted in more reliable and cheaper systems. A cost reduction of up to 14% was achieved.
