Abstract:

The size and complexity of the electrical power system are increasing day-by-day due to the enhanced industrialization and public lifestyle requirements. Thus, the government has allowed private sectors to produce, and distribute electricity within certain rules. After the Electricity Act 2003 (IEA) implementation, the Indian power sector has promoted the restructuring process to encourage competitive environment in the electric power market. Restructuring of the power system leads to the violating transmission operating limits (congestion) in the system due to increased loading and contingencies. The ATC based CM is one of the useful research areas as it helps the market operator (MO) and the market participants to place bids strategically during system security and reliability threats. ATC can be calculated using the linear approximation method (DC power flow, PTDF), continuation power flow method, OPF method, and artificial intelligence approach. It outlines state-of-theart processes, summaries, observations, and issues that need attention in ATC evaluation. Reference discussed the ACT calculation for a 246-bus Indian power system using the DC sensitivity method.
