Hybrid Energy System with an Energy Management Control Strategy Based on the Online Fuel Consumption

Abstract

Many agriculture investments are oriented to the Sahara. Noticeably, they need electricity which is often provided by diesel generators. The refueling process is a real economic challenge due to the very remote area distance which makes it very expensive. To overcome this issue, the hybridization is initiated with the renewable solar photovoltaic energy. That marks an excess or a shortage of power; to cope this uncontrolled power a storage system is compulsory. This work is specific to the pumped hydroelectric storage system which is favorable due to its ecological aspects and the subject matter. The proposed management takes into account the solar temporal variation combined to the pumping scheduling time and real-time fuel consumption optimization. This last proves the PSH’s performance dual function in both the irrigation and power restitution; it also reduces the gas emission and saves fuel. As far as this study is concerned, the suggested control is successfully examined through the management strategy in comparison to that of the literature. Consequently, this study could be helpful for similar future studies. Because, it links the diesel efficiency, solar variation, and dynamic load under the constraints of diesel rated power optimal sizing, PV panels surface, and water tank dimension.
