A Probabilistic Approach for ATC Calculation

Because of the essentially stochastic nature of power systems behavior, mainly due to random equipment outages and load variations, it is very important to consider uncertainties of power systems to promote the accuracy of Available Transfer Capability (ATC) calculations. This paper proposed a probabilistic technique "Bootstrap" to provide an accuracy criteria for ATC estimation that uses historical data and a future postulated condition. The bootstrap is a computer-based method for assigning measures of accuracy to statistical estimates. Test results showed that when the uncertainties of loads and line outages were considered, using the proposed probabilistic approach the confidence intervals could reflect the accuracy of the posted ATC values and it will be more flexible in bidding ATC to further aid transmission customers in their evaluation of transaction biddings and risk analysis.
