Modeling and stability of grid-connected power converters with virtual inertia control by Yang, Haoxin

“…Due to the ever-increasing power demands and a desire for carbon footprint reduction, conventional fossil fuel-based energy generations are gradually replaced by renewable energy sources (RESs), e.g., wind power and solar photovoltaics. However, the lack of inertia contributions from RESs, which are essentially power electronic converters in replacement of synchronous generators, will challenge the frequency control and stability. …”
