Associate Professor

Room: CF626



Dr Siqi Bu received his BEng in Electrical Engineering, BSc in Management of Industry and Business in 2006 and MEng in Electrical Engineering in 2008 all from Southeast University. He obtained his PhD from the Queen's University of Belfast, U.K., in 2011, where he continued his postdoctoral research work in the same department before entering industry. He then worked with National Grid UK as an experienced UK National Transmission System Planner and Operator. He joined Department of Electrical Engineering at The Hong Kong Polytechnic University (PolyU), Kowloon, Hong Kong, as an Assistant Professor in 2016 and then was promoted to tenured Associate Professor in 2020. He is also a Chartered Engineer with UK Royal Engineering Council London, U.K.. He is the Departmental Leader of Engineering Doctorate (EngD) Program & International Student Promotion, Departmental Alumni Liaison Officer, and also the Member of Departmental Learning and Teaching Committee, Departmental Publicity Committee and Student Staff Consultative Group. He is the Leader of Renewable Integration and Smartgrid Application (RISA) research lab and the Research Program Leader of Center for Advances in Reliability and Safety (CAiRS) at PolyU. His research interests are power system stability analysis and operation control, including wind/solar power generation, Plug-in EV, HVDC, FACTS, energy storage system (ESS) and virtual synchronous generator (VSG). For more details in research led by him, please refer to RISA website ( and CAiRS website (


Dr Bu serves as an advisory expert of Hong Kong 1+1 Science Tip-top Talent Scheme and Hong Kong Joint School Science Exhibition Scheme, an advisor of IET Hong Kong Student Section, an external examiner of Hong Kong Vocational Training Council, a review panelist of National Natural Science Foundation of China, a committee officer of IET Hong Kong Power and Energy Section, a committee member of IET Power Systems and Equipment Network UK, and was a committee member of IET Berkshire local network UK. He has been the organizing/technical committee chair/member and session chair of many international conferences and research seminars.


Dr Bu is an Editor of IEEE Access, CSEE Journal of Power & Energy Systems, IEEE Open Journal of Power & Energy and Protection & Control of Modern Power Systems, and a Guest Editor IET Renewable Power Generation, Energies and IET Generation Transmission & Distribution. He is an active reviewer for over 30 peer-reviewed SCI journals and book publishers. He is the Publons Top 1% Peer Reviewer in Engineering and Cross-Field, and has frequently received Publons Peer Review Awards. He is also the recipient of Outstanding Reviewer Awards from IEEE Transactions on Sustainable Energy, IEEE Transactions on Power Systems (3 times in a row), Applied Energy, Renewable Energy, International Journal of Electrical Power & Energy Systems and Journal of Modern Power Systems and Clean Energy respectively. He has received 3 Gold Awards, 2 Silver Awards and 2 Bronze Awards due to excellent performances and outstanding contributions in operational and commissioning projects during the employment with National Grid UK. Moreover, he is the recipient of Research Grant Achievement Award and GRF/ECS Awards from PolyU. In the past four years, as Principal Investigator, he has secured a number of research grants from various funding bodies (e.g., UGC, RGC, ITC, NSFC, GDSTD, MHRD India etc.).

Currently, Dr Bu is proactively recruiting international researchers and PhD/MPhil candidates to support the research to utilize the intelligent computation and data analytics in the power electronized cyber physical power system stability analysis and operation control. You will collaborate with international academic and project partners and develop novel computational and analytical techniques for the following research areas (but not limited to):


1. Application of WAMS/PMU and Big Data technology in power system situational awareness (SA) for event detection and preventive control
2. Application of Data Mining/Machine Learning in the power system stability margin prediction and power equipment predictive maintenance
3. Optimal planning and fully distributed control of distributed energy resources (DERs) considering various constraints, uncertainties and market mechanisms of active distribution network (ADN)/micro-grid
4. Probabilistic/stochastic analysis of power system dynamics considering various system uncertainties
5. Mechanism analysis on emerging stability problems of power electronized power systems including transmission, distribution and micro-grid
6. Cyber physical power system (CPPS) modeling and analysis
