Abstract

Secure operation of electrical power systems is vital, hence fast and accurate post-outage state calculations are important for contingency analysis. Contingency analysis includes simulations of both the single and double branch outages. This paper presents constrained optimization problem of a recently developed double branch outage model. Harmony search algorithm is used as an optimization tool. IEEE 30 Bus Test system simulation results are given, and compared with those of the AC load flow in terms of computational accuracy. Speed test results of IEEE 14, 30, 57, 118 and 300 Bus Test Systems are illustrated and compared with those of the AC load flow calculations.
