About
Kin Cheong Sou received his Ph.D. in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology in 2008. He subsequently held postdoctoral positions at Lund University (2008–2010) and KTH Royal Institute of Technology (2010–2013), and served as Assistant Professor of Mathematical Sciences at Chalmers University of Technology (2013–2016). He joined NSYSU in February 2017 and has been a tenured Associate Professor since February 2022. He also directs the International Master's Program in Electric Power Engineering (IMEPE) at NSYSU.
His research spans optimization modeling and analysis in power systems, uncertainty quantification for distribution networks, renewable energy integration, cyber-physical security, and battery state estimation.
Open position
Postdoctoral Researcher – Power Systems Analysis & Control
The research group invites applications for a postdoctoral position funded under international EU/Swedish/Taiwan collaborative projects with KTH Royal Institute of Technology, Stockholm. The position is initially for one year, renewable to two or three years subject to performance and continued funding.
Sample research topics
- Worst-case and probabilistic load flow for three-phase unbalanced distribution systems
- Robust network reconfiguration and optimal power flow under uncertainty
- Mathematical modeling and control for inverter-dominated power systems
International collaboration. The postdoc will collaborate closely with Prof. Henrik Sandberg (KTH) and is expected to spend up to six months at KTH over the course of the appointment.
