Dr. Abubakar Sani Hassan is an Electrical Engineer with research and industry-based experience in Electrical Energy Systems and the optimization of distributed energy systems. He earned a BEng in Electrical Engineering from the Ahmadu Bello University Zaria, Nigeria. He went on to obtain a master's degree (Distinction) in Energy Systems Engineering from the University of Glamorgan (now the University of South Wales, United Kingdom). During his MSc, he worked on his thesis in conjunction with the University of Glamorgan's Baglan hydrogen center. The key theme of his MSc thesis is the modeling and simulation of a standalone solar-powered hydrogen production system. He has a Ph.D., and as part of his Ph.D. research at the Institute of Energy, Cardiff School of Engineering Abubakar has worked as a research affiliate at the Lawrence Berkeley National Laboratory, California, USA, for two months interfacing energy planning tools with low voltage network models. Dr. Abubakar's projects have always involved several problem formulations and using optimization techniques to optimally find the best schedules for distributed energy resources based on the constraints (physical limitations) defining such systems.
