Statistical method to determine operating rules in the event of generator dropout on EDF French Guyana Grid

Network operation at EDF French Guyana seeks dependability plus optimised use of hydroelectric resources, to reduce overall production costs with no loss of service quality. A requirement is that frequency should not drop below the second load-shedding threshold (47 Hz) in the event of generator dropout. This article outlines a statistical method that examines a large number of simulated network configurations to determine operating rules accommodating optimisation capable of meeting cost reduction targets.
