The Interest of Connecting Mini Solar Stations to the Public Electricity Grid in a Desert Environment

Abstract

The transportation of electrical energy produced by the different kinds of power plants is one of the real problems and challenges in the distribution energy field. Indeed the loss caused by the joule effect (thermal loss) can never be neglected, especially when the cables network are very long. Moreover, in desert environments where the temperature is very high during many months of the year, the loss in the electrical conductors becomes more important. As a solution, the network reinforcement using decentralized sources (the mini solar stations) is proposed to recover practically all the loss and guarantee the improvement of the system efficiency. In this paper we will present a study by simulation (using the PVsyst software) which demonstrates the direct connection of a mini solar station (peak power of 31500 Wp) to the public electricity grid which justifies the interest of this operation to improve the energy efficiency.
