Dr. Wakui has been studying on wind power generation from the viewpoint of the system engineering approach. He is currently an associate professor at the department of mechanical engineering, Osaka Prefecture University. After getting the Ph.D. in the optimal design and control of stand-alone wind turbine generator systems in 2001, he spent 4 years at Waseda University and then transferred to the current university. The current his study focuses on the optimal control for floating offshore systems as well as grid-connected and stand-alone systems and the optimization of distributed energy supply systems.
