The Design and Realization of Smart Energy Management System based on Supply-Demand Coordination

Sub-Saharan Africa in recent years have been faced with many power challenges including limited and unreliable power supply, high cost of power supply and underdeveloped power infrastructures with serious negative impacts on the socio-economic development. This paper presents the development of Smart Energy Management Solution (SEMS) for buildings. The work seeks to propose a generic algorithm that supports existing wiring infrastructure of buildings in Africa to provide 24/7 reliable power supply and efficient management of limited power supply in buildings. SEMS focuses on the use of robust, distributed and heterogeneous power sources connected in islanding phenomenon to ensure reliability and also using a dynamic approach with energy efficiency measures to provide a balance between power supply and demand in buildings. A demonstration of SEMS for buildings was performed in MATLAB Simulink using actual data obtained from selected buildings at Kwame Nkrumah University of Science and Technology (KNUST), Ghana SEMS revealed higher power reliability and efficiency in energy usage.
