African Renewable Energy Potentialities Review for Local Weak Grids Reinforcement Study

This paper presents a literature review based standalone microgrids including the hybrid renewable energy sources (wind, solar PV, hydroelectricity) with energy storage systems. Some configurations of the hybrid systems based on the DC-bus and AC-bus are proposed. A general overview is given on the renewable energy potentialities in Africa, and in particularly in Guinea where the rural electrification is today major challenges. Several control strategies related to the intermittency of the renewable energy sources are analyzed. The methods are generally focused on energy production optimization, energy conversion performances, microgrid stability, multi-source energy management strategies. Different architectures and topologies of the most common converters and filters used in hybrid renewable energy applications are also discussed. Potential solutions and research trend are identified through the synthesis of recent studies proposed in the literature.
