Technical seminar

Title of lecture 1: Medium Voltage Power Electronics in Smart Grid Applications;

Duration:

Before the lecture, Prof.Ronghai Qu gave an introduction about Prof.Po-tai Cheng to the audiences and a warmly welcome for his visit to Huazhong University of Science & Technology.

Prof. Cheng began his lecture with the current situation and future plan of renewable energy in Taiwan. Then, Prof. Cheng exhibited his work on medium voltage power electronics applications. Two kinds of power electronics modules, single-star bridge cells (SSBC) and single-delta bridge cells (SDBC), are analyzed under different load conditions and balance conditions. He also talked about performance difference between different cells under voltage sag incidents. Through research, his team came to a conclusion that unbalanced conditions lead to stress due to phase cluster balancing. At the end of his speech, Prof. Cheng took EV charging as an example to show the other applications of power electronics. Siemens fast charge, Tesla super charge and solid state transformer are introduced.

After the lecture, the audiences actively asked questions about the topic of power electronics in smart grid, for example, “how will the neutral Y connected affect the smart grid?”, “how about the manufacturing and material development of power electronics?”. Prof. Cheng gave the answers to these questions in detail. Prof. Cheng’s clear logic and lucid expression showed his excellent work and rich experience in his research field.

Through this expert lecture, the audiences learned a lot of latest knowledge and research methods about smart grid as well as the power electronics. The lecture ended in the warm applause.
