Abstract
This paper presents a method to predict the postcontingency security margin
using radial basis function (RBF) networks.  A genetic algorithm-based feature
selection tool is developed to obtain the most predictive attributes for use
in RBF networks. The proposed method is applied to a thermal overload problem
for demonstration. Simulation results show that the proposed method gives
satisfactory results and the running time decreases by a factor of 10 compared
with using multilayer perceptrons.
Keywords: Security margin, power systems, radial basis function networks,
genetic algorithms, feature selection
