North Africa grid interconnection weakness: Impact on the Tunisian PES emergencies

North Africa grid interconnection weakness: Impact on the Tunisian PES emergencies

On august 31, 2014, a generalized power outage impaired the Tunisian power system. This event was particular in the time frame of the cascaded failures, where weak cross-border grid interconnection stood out as a determinant factor. North African interconnections did not support the Tunisian system...
