Alternatives for calculating Transmission Reliability Margin (TRM) in Available Transfer Capability (ATC)

Research output: Contribution to journalConference article


There is very little theory developed for the calculation of the Transmission Reliability Margin (TRM) in the Available Transfer Capability (ATC) computation of electric power systems. This paper proposes and evaluates several different approaches to the calculation of TRM. The TRM is supposed to account for uncertainty in the operating conditions used in computing Total Transfer Capability (TTC). This uncertainty may be in model parameters (line impedances), load forecast error (P and Q), or other `base case' data.
