Assessment of Available Transfer Capability for Congestion Management in Restructured Electrical Power Network for Competent Operation

Abstract

Congestion is the prime cause of problems, due to open access of power system. The AC Power Transmission Congestion Distribution factor (PTCDF) is suitable for computing change in any line quantity for a change in MW bilateral transaction. The proposed PTCDF method is more accurate as compared to the DC power distribution factor. With PTCDF ATC can be calculated. After calculating ATC it is possible to know the valid multiple transaction on power system. With the help of ATC calculations congestion problem can be solved in restructured electrical power network. The paper presents the method for calculating ATC using PTCDF.

Assessment of regional transmission connection capacity based on two novel indices

“…Price area congested management deals with the problem via area price model and counter trade [3]. ATC is a measure of the transfer capability remaining in the physical system for future activities over and above already committed uses [4], and used for alleviating congestion by giving power transfer capability available in the system for a particular transaction [5]. ATC is employed in operational planning [6–8].…”
