History, Our Endeavours, and Future Research of Grid-Forming Converters
Seminar Abstract:
Driven by the growing energy demand and reduction of carbon footprints, there is a global energy shift evidenced by the large-scale integration of renewable energies into modern power grids. As the core of renewable generation, grid-tied converters mainly follow the established grid and operate as controllable current sources for active/reactive power regulation, known as grid-following converters. Although being mature and simple, grid-following converters pose serious threats to the operation of power grids and impose a limitation on the ratio of renewable energy penetration, due to the incapability of grid formulation and inertia/damping delivery as well as poor instability in weak grids. Fortunately, grid-forming converters are evolving as a solution and the enabler of modern power grids.
This talk will unfold itself with a history of grid-forming converters, with a special focus attached to the voltage source and current source features. In parallel, major grid-forming techniques will be reviewed and compared. Subsequently, our endeavors on the modeling and control of grid-forming converters serve as the major part of this talk, including classifications from both AC and DC perspectives, small-signal and large-signal modeling, as well as the inner-loop voltage control, middle-loop power control, and outer-loop coordination control. Finally, this talk will point out the potential future research directions of grid-forming converters as the form of questions.
