DYNAMIC AND STATIC SECURITY ASSESSMENT OF POWER SYSTEMS

What follows is a summary of some of the authorsf work on two types of security problems. In this work we used a layered perceptron with two training algorithms, a projection algorithm and aa error backpropagation algorithm. The projection algorithm is based on the least squares approximation technique and the error backpropagation on the steepest descent technique. 1. Dynamic Security Preliminary results were obtained from studies of the dynamic security of a 9 buses, 3 generators, and 14 transmission lines t e s t system. Our f i rs t study analyzed the relationship between system stability and the output power of generator 3, the excitation of generator 3, the apparent power of load 8, and the availability of lines 9 and 10. The results were reported in [I]. Some of these results ar
