On the morning of May 22, 2018,at Unit 201, Yuquan Campus, Zhejiang University, Dr. Li Qifeng, assistant professor and doctoral supervisor of Department of Electrical and Computer Engineering at the University of Central Florida, brought an academic report titled Convex Optimization in Power Systems and Fluid Networks to our teachers and students.The report was presided over by Prof. Xin Huanhai from the College of Electrical Engineering. College teachers and student representatives participated in the report.
This academic report focuses on convex optimization in power systems and fluid networks. Dr. Li introduced the advantages and types of convex optimization, the basic concept of convex relaxation, and the latest developments, and illustrated the examples of the convex grid model, the convex battery model, the convex fluid network model, and the stability constrained optimization framework.
Many mature optimization algorithms are computationally effective and robust for solving convex problems. It is fundamental in both distributed optimization and bi-level optimization.Convex optimization has gained academic excellence with its great advantages. The wide attention of the community has certain applications in convex relaxation methods such as SDP, ESD, and SOCP.
Currently, Dr. Li's team has developed a tighter convex relaxation for the AC power flow in the general network. Next, it will continue to study the optimization and control of hybrid energy systems, microgrids, and optimal demand-side management in market environments.
After the report ended, Dr. Li Qifeng had a lively discussion with relevant teachers and students on related issues. Dr. Li expressed that he would welcome further exchanges with the teachers and students of the College of Electrical Engineering.
