Social impact based contingency screening and ranking

Byline: James A. Momoh, Yi Zhang, Philip Fanara Jr., Haydar Kurban, L. Jide Iwarere This paper develops a new index to rank the contingencies in different partitioned areas of networks. The new index considers the social and economic impacts of the contingencies and ranks them by using an overall index that combines these effects with technical factors. This overall index is implemented in the Western Systems Coordinating Council (WSCC) system. Load flow is run in different scenarios; and real power losses, Available Transmission Capability (ATC), and Expected Socially Unserved Energy (ESUE) are compared.
