Abstract: This article comes as a contribution to the development of a specific roadmap with the intention to transform the RIS into a smart grid, based on examples experimented in other countries, surveys, interviews with resource people and the master plan of energy development in Cameroon. To set up this roadmap, an audit of the current network reveals many dysfunctions such as regular power outages, imbalances, losses power. The proposed roadmap is structured around three stages which can be summarized as follows: in the short term, the establishment of a reflection committee, his Functional organizational chart and its timeline of activities have been proposed; in the medium term, the deployment of certain equipment such as smart meters; finally, in the long term, the complete transformation of the current network into a smart grid. This will make it possible to integrate the renewable energies which are in development in African countries. It can serve as a guide for the deployment of smart grids in countries of the sub-region of Africa and in Cameroon in particular. The lack of related studies and the non-popularization of results by those who have already worked on those issues, make this paper a greater contribution for energy policy and development, mostly for sub-Saharan African countries.

Abstract: This study has been focused on the vertical profile determination of the winds under a neutral atmosphere in order to assess of the wind power density at three sites in Guinea. The power law has been used as an extrapolation model for wind speed. The Weibull function has been used to estimate the wind power density. The satellite data at 10 m above the ground recorded during the period from January 2001 to December 2015 on the sites of Conakry, Mamou and N’zérékoré sites were used. The results indicate that the Conakry site is the windiest of the three study sites with an average speed estimated at 2.83 m.s-1 at 10 m and 4.23 m.s-1 at 100 m above the ground. The form parameter k of Weibull varies from 1 to 1.8 and the scale parameter c from 1.5 to 6 m.s-1 and are both increasing functions of altitude. Finally, the quantities of energy obtained at the three sites reveal that only the Conakry site could be suitable for the installation of small wind turbines for the wind energy production. The average annual density is estimated at 45.77 W.m-2 at 10 m; 85.62 W.m-2 at 50 m and 113.31 W.m-2 at 100 m. On the Mamou and N’zérékoré sites, the pumping water from multi-blade wind turbines could be considered.
