use of probabilistic methods to consider the impact of uncertainty has been used extensively in power systems . These concepts may prove useful in quantifying TRM from a probabilistic approach. Expected values of ATC numbers could be used for TTC with variances
Alternatives for calculating transmission reliability margin (TRM) in available transfer capability (ATC)

The increase of the transmission capability depends on the accuracy of the offline ATC or TTC calculation. In general an increase of about 3 % can be expected. This safety margin can be reduced, if control- lable network devices limit the power flow over a criti- cal line.
