Island formation in entergy power grid during Hurricane Gustav

Hurricane Gustav made landfall on September 1, 2008, Southwest of New Orleans, LA. Several transmission lines were outaged and an electrical island was formed in an area including the metropolitan New Orleans, LA. The island was sustained for several hours before the system was restored. This paper discusses the issues associated with maintaining an island, results of the dynamic simulations performed to replicate the island, and issues associated with restoring the island.
