Dr BU Siqi

Associate Professor and Associate Head

BEng, BSc, MEng, PhD, CEng, MIET, SMIEEE


Dr Siqi Bu received his BEng (Hons) in Electrical Engineering, BSc (Hons) in Management of Industry and Business in 2006 and Meng (Distinction) in Electrical Engineering in 2008 all from Southeast University. He obtained his PhD from the Queen's University of Belfast, U.K., in 2012, 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 and Electronic 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 Electrical Engineering (EE) Program, and the Member of Faculty Research Committee (FRC). He is the Leader of Renewable Integration and Smartgrid Application (RISA) research lab and the Research Program Leader of Centre for Advances in Reliability and Safety (CAiRS) at PolyU. His research interests include power system stability analysis and operation control, considering renewable energy integration and smart grid application.

Dr Bu serves as a Standing Director of IEEE PES Power System Relay and Control Satellite Committee (China), the Secretary of IEEE PES Long Range Planning Committee, an advisory expert of UK Government and IET on Enabling Distribution System Operation Transition Strategies, TUS-CLP Smart Energy Technology Co. Ltd., 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, National Natural Science Foundation of China and Ministry of Science, Technology, Knowledge and Innovation of Chile, and an International Examiner of PhD Candidate Dissertation and Examination, and an EMSD Appeal Board/Reviewing Panel Member. He is the Chair of Task Force on Promotion and Outreach of IEEE Open Journal of Power and Energy. He is the Vice Chairman of IET Hong Kong Power and Energy Section, Chairman of IET HK Power Symposium 2024 and Co-Chairman of IET International Conference DPSP 2025.


Dr Bu is an Editor of IEEE Transactions on Power Systems, IEEE Transactions on Consumer Electronics, IEEE Power Engineering Letters, IEEE Access, IEEE Open Access Journal of Power and Energy, CSEE Journal of Power & Energy Systems, Protection & Control of Modern Power Systems, Journal of Modern Power Systems and Clean Energy, and PeerJ Computer Science, a Guest Editor-in-Chief/Editor of Renewable & Sustainable Energy Reviews, IET Renewable Power Generation, IET Generation Transmission & Distribution, IET Smart Grid, IEEE Access, Energies, Frontiers in Energy Research, Shock and Vibration and Smart Cities, and a Moderator of IEEE TechRxiv Preprint. He is an active reviewer for over 50 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/Excellent Editor Awards from IEEE Open Access Journal of Power and Energy, CSEE Journal of Power and Energy Systems and Protection and Control of Modern Power Systems, and Outstanding Reviewer Awards from IEEE Transactions on Sustainable Energy, IEEE Transactions on Power Systems (7 times in a row), IEEE Transactions on Power Delivery, 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 Faculty Research Grant Achievement Award and Presidential GRF/ECS Awards from PolyU. In the past five 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, SHUA 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 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 Machine/Deeping Learning in power system stability margin prediction and contingency screening
  3. Optimal planning and fully distributed control of distributed energy resources (DERs) considering various constraints, uncertainties and market/trading mechanisms of active distribution network (ADN)/micro-grid
  4. Probabilistic/stochastic analysis of power system dynamics considering various system uncertainties
  5. Stability mechanism analysis of power electronized power systems including transmission, distribution and micro-grid
  6. Cyber physical power system (CPPS) modeling and analysis
  7. TSO and DSO coordination and optimization
  8. Power and transport nexus: coordination and optimization
  9. Carbon emission flow tracking, analysis and optimization
  10. Power equipment predictive maintenance and Prognostics and Health Management (PHM)
