Secure operation of power system is a big concern in recent power industries. Contingency selection and ranking method used is very important for the security assessment. The multilayer feed-forward artificial neural network and radial basis neural network for implementation of online static assessment take less time to assess the contingency. Composite security index is used for contingency selection and ranking. Generation power, load power, and voltages are used as input to the artificial neural network (ANN) and composite security index is decided by the trained data of ANN. In this paper, radial basis neural network is trained with particle swarm optimization (PSO) to reduce the training time and improve the accuracy. MATAB 2013a is used for building algorithms and testing. IEEE 30 bus system is used as the test system. Single line removal is taken as contingency conditions.
