ATC for congestion management in deregulated power system

Enhancement of Available Transfer Capacity for Congestion Management In Deregulated Power System Guided by : Prof. S. K. Joshi M.S.U. Baroda Presented by B.P.Pandya , BE(E) IV Roll No. : 424

Project Theme ,[object Object],[object Object],[object Object],• To propose a new set of AC sensitivity referred as “ AC Power Transfer Congestion Distribution Factor (ACPTCDF) “ for 6 bus system. • Calculate ATC of transmission line • Enhancement of ATC using facts devices for congestion management

Objective of Congestion Management ,[object Object],[object Object],[object Object],[object Object]

Available Transfer Capacity (ATC) “ ATC is a measure of the Transfer Capability Remaining in the transmission network for further commercial activity* over and above already committed uses” (* while ensuring system security) Mathematically, ATC = TTC – TRM – (ETC+CBM) [In accordance with the recent FERC (Federal Energy Regulatory Commission) Order 888 (Promoting Utility Competition Through Open Access, Non discriminatory Transmission service by Public Utility)& 889(OASIS , Open Access Same time Information system) , ATC must be calculated for electric utility] .
