Suggested Analytic Approach to Transmission Reliability Margin
نویسندگان
چکیده
Transmission Reliability Margin (TRM) is the component of available transfer capability that accounts for uncertainties and safety margins. We suggest an analytic framework for TRM calculation using transfer capability sensitivity formulas and a probabilistic characterization of the various uncertainties. Preliminary results on a simple example show how we plan to test the TRM calculation and validate it with a Monte Carlo method. This draft report is produced in order to seek comment from PSerc members on the practicality and usefulness of this approach to TRM.

In this paper, the new approach for the transmission reliability cost allocation (TRCA) problem is proposed. In the conventional TRCA problem, for calculating the contribution of each user (generators & loads or contracts) in the reliability margin of each transmission line, the outage analysis is performed for all system contingencies. It is obvious that this analysis is very time-consuming fo...

Uncertainty of system operating conditions is one of the causative reasons which may render to the instability of a transmission system. For that reason, accurate assessment of transmission reliability margin (TRM) is essential to ensure effective power transfer between areas during the occurrence of system uncertainties. The power transfer is also called as the available transfer capability (A...
