SUMMARY:Control of renewable-energy-dominated power systems
DESCRIPTION:Renewable energy is the key to achieving carbon neutrality. However\, the large-scale integration of renewable energy sources poses tremendous challenges to the stable operation of modern power systems\, as the systems become much more complex and are under lots of uncertainties. In particular\, the grid interface of renewable generators (i.e.\, power electronics converters) generally have distinct dynamics compared with traditional fossil-fuel-based synchronous generators\, resulting in new stability problems in practice. Moreover\, it has been widely recognized that conventional PLL-based control methods of power converters cannot support a stable renewable-energy-dominated power system because they have no grid-forming capability. Hence\, it is essential to develop advanced control strategies for power converters. This talk will introduce the challenges in controlling a renewable-energy-dominated power system and discuss how we can possibly understand the dynamics of such a system. I will present my research works in designing stabilizing\, robust\, and optimal controllers for renewable generators to handle uncertainties in the system and enable their grid-forming capabilities. I will demonstrate how data-driven control can equip renewable generators with adaptability and ensure robust and optimal performance under variable grid conditions. Moreover\, I will discuss other open problems in renewable-energy-dominated power systems and envision future research directions.\n \nBiography of the speaker: \nLinbin Huang is a postdoctoral researcher at ETH Zurich since September 2020\, working in the Automatic Control Laboratory. He received his Ph.D. degree in College of Electrical Engineering at Zhejiang University in 2020 and a B. Eng. degree from the same institution in 2015. From 2018 to 2019\, he was a visiting scientist at ETH Zurich. His research interests include power system stability\, optimal control of power electronics\, and data-driven control. \nAll are welcome.
