摘要
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. (C) 2004 Elsevier Ltd. All rights reserved.
