Research Interests
Dr. Xueqin (Amy) Liu received the Ph.D. degree in Electrical and Electronic Engineering from Queen's University Belfast (QUB), Belfast, U.K., in 2009, under joint training with the Institute of Cyber-Systems and Control at Zhejiang University. She continued her academic career at QUB as a Research Assistant (2009-2011), Lecturer (2013-2019), and Senior Lecturer within the School of Electronics, Electrical Engineering, and Computer Science.
Her research involves close collaboration with the industry to address emerging challenges in power system operation and the integration of battery energy storage. She has published over 80 papers in leading journals and conferences. She served as a Co-Investigator, leading QUB’s research in the €6.7M INTERREG SPIRE2 project (with QUB's share being £1M). The project aims to investigate a Storage Platform for the Integration of Renewable Energy on the Island of Ireland. Her QUB SPIRE2 team has developed a diagnostic software for identifying the source of oscillations which has been tested, validated in EirGrid & SONI. Her team has won the Best Graduate Student Poster Award at the prestigious 2021 IEEE Power and Energy Society General Meeting.
She has contributed her energy analytics expertise as a Principal Investigator (PI) or Co-Investigator (Co-I) for various projects, including the EU Horizon 2020 project ‘Future-Proof,’ the British Council project ‘TIIWAM,’ the £11M Ofgem low carbon networks project ‘Smart Street,’ and the EPSRC industrial CASE project ‘load forecasting.’
She is a former director of QUB’s MSc in Electrical & Electronics Engineering, a Senior Member of IEEE, an Associate Editor of Energy Conversion & Economics (IET), and a member of the IEEE Women in Power Society.
