A Transmission Network Planning Method for Comparative Studies

An automated transmission network planning method for comparative studies is presented. This method employs logical steps that may closely parallel those taken in practice by the planning engineers. Use is made of a sensitivity matrix to simulate the engineers´ experience in selecting the contingency cases to be studied and for the selection of branches to be reinforced. The network is expanded to satisfy a given reliability criterion over the planning period. A representative example showing the application of this method to the IEEE 14 Bus Test System is presented.
