Power systems worldwide are transitioning to higher penetration of non-synchronous renewable energy sources (RESs) (e.g., wind and solar) and less traditional thermal generation. This change in the generation mix brings significant operational challenges to transmission system operators (TSOs). These challenges include frequency, voltage and transient stability, as well as congestion and power quality issues, among others. For example, it is well-known that RESs provide fluctuating production, less inertia and voltage support. While such challenges are being recognized by TSOs how to deal with them is still an open question. In this context, the aim of this special session is threefold:
Furthermore, the special session includes distinguished researchers from both academia and industry that will shed light on the recent solutions proposed in the literature.
