Failure and fault classification for smart grids
Energy Informatics, 2022 AbstractSmart grid (SG) has been designed as a response to the limitations of traditional power grids caused by growing power supply demands. SG is considered a critical infrastructure in which dependability plays a crucial role and manifestation of failures can lead to severe consequences.
