Session Title: Modeling and Control of Grid Forming Converters in Modern Power System
In order to build a modern power system with renewable energy as the main body, converter-based wind and solar power have been widely installed in the power system globally. Unlike conventional synchronous generator-based thermal power, conventional converter-based resources lack inertia and voltage support ability, which would cause many instability issues. Thus, the grid-forming (GFM) converter has received much attention and research due to its excellent voltage source characteristics, which can support the frequency and voltage of the modern power system with high-penetration renewable energy. However, the GFM converters feature non-linear multi-time scale dynamics, which also cause potential wide-band frequency resonance issues under different perturbations. To improve the overall stability of GFM converters, both the modeling and control issues should be considered and worthy of study. The comprehensive modeling of GFM converters is essential for revealing the underlying mechanism of different resonance problems and the advanced control methods are indispensable for ameliorating the stability of modern power systems. Topics of interest include, but are not limited to:
