Impact of high penetration of grid forming converters in a large-scale power system

Abstract

The stability of large-scale power systems is being challenged by the high penetration of converter interface generation (wind and solar photovoltaic).Synchronous generators must be committed to guarantee the stability of a large-scale power system in scenarios of high penetration of renewable energy sources connected through grid following converters.The talk will show how the massive incorporation of grid-forming converters can avoid such must-run synchronous generation.Models and test cases of the Spanish power system with representations of the external systems will be used for the illustration.
