Error analysis in electric power system available transfer capability computation

Research output: Contribution to journalArticlepeer-review


A key concept in the restructuring of the electric power industry is the ability to accurately and rapidly quantify the capabilities of the transmission system. Transmission transfer capability is limited by a number of different mechanisms, including thermal, voltage, and stability constraints. This paper discusses the available transfer capability (ATC) definitions and determination guidelines approved by the North American Electric Reliability Council (NERC) and presents several concepts for dealing with the potential errors and technical challenges of computation.
