Haiyu Li

Professor Haiyu Li is a Professor of Power System Dgtsn & Auto in the Department of Electrical Engineering at The University of Manchester. His research interests include Power systems digitisation and automation, with a focus on Smart Grid – active distribution network voltage control and digital technologies such as IEC61850 digital substation automation systems, cyber security, and resiliency. His work has contributed to the development of flexible and sustainable electric power systems, including the creation of new business opportunities for UK distribution network operators. He has published extensively in IEEE and IET journals and has been involved in several high-impact projects, including the Virtual Site Acceptance Testing and Training (VSATT) project and the IEC61850 Cyber Resilient Electrical Substation Technologies (CREST) project.

Haiyu Li's research focuses on power systems, with an emphasis on fault detection, protection, and optimization in distribution networks. Key areas include voltage sag analysis, fault location using voltage sags measurements, and the integration of distributed generation. Li's work explores advanced techniques such as neural networks, genetic algorithms, and global positioning systems for data synchronization to enhance system reliability and performance. Additionally, Li investigates reactive power dispatch, load shedding, and the economic feasibility of renewable energy integration. The research also addresses the impact of transformer energisation on voltage dips and the use of tap stagger operations for ancillary services in transmission systems.
