Quantifying transmission reliability margin
نویسندگان
چکیده
In bulk electric power transfer capability computations, the transmission reliability margin accounts for uncertainties related to the transmission system conditions, contingencies, and parameter values. We propose a formula which quantifies transmission reliability margin based on transfer capability sensitivities and a probabilistic characterization of the various uncertainties. The formula is verified by comparison with results from two systems small enough to permit accurate Monte Carlo simulations. The formula contributes to more accurate and defensible transfer capability calculations. q 2004 Elsevier Ltd. All rights reserved.

With the further development of power markets, large amount of electric power wheeling and frequent transmission transaction is emerging, accurately determining Available Transmission Capability (ATC) and broadcasting the ATC information in time are very important to prevent and relieve transmission congestion effectively. In practical power markets, there are large amount of uncertainties invo...
متن کاملSuggested Analytic Approach to Transmission Reliability Margin
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 v...

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...

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 (TT...

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...
