Modeling of Energy Stored by a Pumped Storage Power Plant Using Wind Energy and Meteorological Data in Cameroon

Résumé

The particularity of renewable energy is its intermittency.One of the ways to make these sources exploitable is to propose efficient storage methods.This study develops a solution for storing wind energy, by gravity storage through water retention (wind-PSP system), and evaluates their effectiveness in the energy context of Cameroon.The methodology focuses on the use of wind energy to pump water to an upper basin.The methodological approach is based on mathematical and statistical modeling (water flows and wind distribution).These include the choice of study area using topographic data, digital terrain models applications and tools such as Google Earth, Global Positioning System (GPS), ArcGIS.The simulation model leads to an average available power of 12 MW for two water reservoirs with capacity of 95 m 3 and 10 m 3 whose heights are respectively 200 m and 2300 m above sea level.The field study contributes, with an experimental flow rate value of 4.42 m 3 /s, to support the site selection criterion due to the values in agreement with the literature.These results are encouraging and could be improved depending on the site.
