Transmission line congestion management in liberalized environment

摘要

The energy market is continuously emerging from the past few decades. An open access to the energy market has led to the problem of energy market's management. This is aroused due to congestion. Therefore, it becomes prominent to impose some restrictions on it to mitigate congestion problems. Amongst from different available methods like re-scheduling; re-dispatching, etc. some more CM techniques have been incorporated with soft computing procedures to provide fast solutions of congestion management. Hence by imposing barrier on various security limits, CM methods confine system secure by restricting system constraints within operating limits. This research report explores the solutions of congestion management problem in power system networks. The optimal location for placement of a DG (distributed generator) has been found out on the basis of weakest bus identification in power system network and hence overall cost has been calculated after placement of DG. The proposed method has been applied on IEEE-14, IEEE-30 and IEEE-57 bus system. The overall costs have been compared after placement of DG with before placement of DG.
