A. Prof. Jiashen Teh-2.pngJiashen Teh

Universiti Sains Malaysia, Malaysia

Dr. Teh demonstrates the advantages of flexible transmission line rating on high voltage (138-400kV) power grids to enhance the integration of solar and wind energies. The research is state-of-the-art because the new relationships of the flexible line rating technology with existing conditions and legacy technologies are investigated.  The research enables the optimal enhancements of line ratings while preserving the life-cycle of transmission lines, and thereby improving the reliability of transmission grids. With this new discovery, electric utilities worldwide can safely increase the power capacity of their existing grids, which can enhance the integration of renewable energy and improves the delivery of clean energy to consumers at a minimal cost. Consequently, the dependency on traditional, carbon-emitting fuels is reduced. This assists electric utilities to reduce carbon emissions and, enable them to commit to higher level of ESG standard. Dr. Teh is also a Technical Director of UPE-Power in Taiwan, which he has implemented his research findings on line sensor products developed for applications in Taiwan and Japan. He has published more than 50 journal articles indexed in the globally recognized SCIE database, which he is the first/corresponding author in 34 (>70%) of them, and 30 (>65%) of the articles are ranked in the database’s first quarter. His publications have attracted 2085 citations and 28 h-index on Google Scholar. He has secured around RM800k of research funding, where more than 40% of the amount was obtained abroad (Taiwan, Saudi). He has accumulated RM30k of local consultancy projects. He has 1 pending patent filed in Malaysia. He is the main supervisor of 4 graduated PhD students, and another on-going 9 PhD students. For three consecutive years in 2019, 2020 and 2021 he was the top 2% world-most-cited-researchers according to field by Stanford University. He was the 2021 Outstanding Engineer by the IEEE Power & Energy Malaysia and the 2022 Outstanding Young Professional by the IET Malaysia.
