Digital Twin Makes Power Grid Smarter

10：00-11：00

Jiangtao Li is a professor and doctoral supervisor in the School of Electrical Engineering, Xi'an Jiaotong University, a member of IEEE, and a scientific editor of High Voltage. He has B.S. and M.S. degrees in engineering from Xi'an Jiaotong University and a Ph.D. degree in engineering from the National University of Singapore, focusing on the study of intelligent sensing of power equipment, pulsed power technology, and plasma, and bioelectromagnetism. He has presided over more than 30 national/provincial/ministerial-level and military projects, published more than 50 research papers in domestic and international academic journals, and applied for more than 20 patents. He has also presided over 3 educational reform projects and the construction of international graduate full English courses. His graduate students have won many prizes in electronic design, innovation, and entrepreneurship competitions. He has won titles of Excellent Party Member, Excellent Teacher, Advanced Individual in Teaching, and Excellent Instructor of Postgraduate Electronic Design Competition.

The digital twin can digitally map the physical entities of the grid to virtual space; integrate emerging technologies such as big data, artificial intelligence, and cloud computing; and diagnose, evaluate, and predict the state of the grid as well as important power equipment in digital space through real-time multi-physical information in physical space, thus realizing the refinement, systematization, and full intelligence of the grid at different levels. This talk focuses on the basic concept of the digital twin, related involved core technologies, and the future outlook when combined with the grid.

MEMS and Entrepreneurship

11：00-12：00

Yunjia Li received a Ph.D. degree from the group of Micro and Nanosystems, ETH Zurich, Switzerland, in 2014. From March 2014 to July 2015, he worked as the CTO of microGauge (Currently microGauge AG, Zurich, Switzerland, www.microgauge.ch), where he was in charge of developing a high-precision MEMS resonant vacuum pressure sensor and won the “Venture Top5” and “Venture Kick Finalist” awards in 2015. Since January 2016, he has been an associate professor at the School of Electrical Engineering, Xi’an Jiaotong University. He is also a senior member of IEEE, the chair of the technical committee on MEMS and nanotechnologies of IEEE Industrial Electronics Society (IES), a member of the IEEE IES AdCom and IEEE Nanotechnology Council AdCom, and a member of the IEEE Nanotechnology Council Standards Committee. He served as track and session chairs of the Annual Conference of the IEEE Industrial Electronics Society in 2019, 2020, and 2021 and the IEEE International Conference on Industrial Technology in 2020 and 2021. His research interests include capacitive/inductive sensors, actuators, and energy harvesters, on both device and system level.

Microelectromechanical systems (MEMS) technologies enable the fabrication and integration of sensors and actuators on an ultra-miniaturized scale, significantly improving the performance and cost over traditional sensors and actuators. In the past decades, the unprecedented development of consumer electronics and the intelligent industry has boosted the technology and market needs of MEMS devices, creating strong market demand and enormous opportunities in academia and the MEMS industry. In this talk, the fundamental concepts, fabrication technologies, packaging, and integration methods of MEMS devices will be introduced. Next, the possibilities and typical routes towards MEMS devices commercialization will be explained based on real-world industrial examples. The talk will primarily focus on the general approach of creating a technological start-up company from the technology developed in a university environment, which might be helpful for technical entrepreneurship enthusiasts.
