Abstract: In competitive electricity market, the power system is unbundled into Gencos, Transcos and Discos. In this environment, the market schedule will driven based on purely economic basis without security concern. The remedial actions for insecure schedule will leads to the market for economic inefficiency. The inability of the transmission system to dispatch market required schedule is known as congestion and the corresponding excessive generation cost with congestion relief action termed as congestion cost. This can be defined in a variety of ways. Each definition reflects the design objectives and cost-recovery policies of the particular market. In this paper, three major generic approaches are reviewed which already using by many electricity markets. The approaches are analyzed on IEEE-30 bus system and Indian utility 62 bus system.
Keywords: Congestion cost, Restructured power system, Gencos, Transcos, Discos.
