Modern power grids are undergoing significant infrastructure changes as power electronics-dominated power conversion systems are increasingly employed with renewable energy systems. Compared with electrical machines, a radical change with power electronics converter is the lack of physical electromechanical laws, and their dynamics are more dependent on the control system, which leads to growing dynamic issues and pose new challenges to the stability and reliability of power grids. This course will provide a systematic study on power conversion control in the renewable energy system, by which the fundamental mechanism of various dynamic issues can be revealed with physical insights and impacts of control parameters can be quantified. To improve the learning experience, Challenge Based Learning (CBL) will be implemented in this course. On the one hand, the industrial partner will be invited to deliver the course together and provide the big picture of the real-field challenges and last technology development. On the other hand, hands-on experimental activities will also be implemented to bridge the gap between theory and practice. You will be able to validate the power conversion knowledge directly in the flexible experimental platform. You will be also challenged with new real-field problems and need to solve them in groups creatively.
