Abstract
In the competitive power market environment , congestion is an indicator for the need of transmission system reconfiguration by compensation devices or its expansion with new lines erection. Due to economic considerations, the short time solution like re - dispatch is also playing a key role in the present scenario. In some inevitable cases, moderating the congestion by load shedding is the only solution which is not good in practice. Hence this paper addresses a solution for congestion relief, i.e. r e - scheduling of generators if required simultaneously with load reduction . In re - schedule method, some of the generators are required to increase/decrease their actual market schedule which causes to increase/decrease transmission losses. Si multaneously, the increase in production cost so called congestion cost . The IEEE - 6 bus and IEEE 14 bus test system s are used to show the effectiveness of the proposed method .
