Claim:
1. A method of performing a contingency screening of an electrical power network, the method comprising: receiving a previously computed, modular representation of the electrical power network, wherein the modular representation includes: receiving a line outage having an outage type, including receiving a line outage for which the outage type is an internal outage; determining whether to recompute the zoomed-out representation or both of the zoomed-in and zoomed-out representations as a function of the outage type, including determining that both of the zoomed-in and zoomed-out representations need to be recomputed based on the internal outage; and recomputing, based on the line outage, the one(s) of the zoomed-in and zoomed-out representations determined at said determining step, including recomputing both of the zoomed-in and zoomed-out representations as a function of the internal outage; wherein recomputing the zoomed-out representation includes recomputing the zoomed-in representation to account for an outage and performing a forward transformation as a function of the recomputed zoomed-in representation to produce a recomputed zoomed-out representation.
