摘要：

Normally, the available transfer capability of the study transfer is obtained for a given base power flow. If once the node power changed, the available transfer capability calculation is carried out, a lot times of calculation will be needed, as the commercial software of managing and utilizing system transmission (MUST) does, which will cost a lot of computation time. Based on the processing of the available transfer capability by using distribution factors, the sensitivity of available transfer capability with respect to the node power is proposed. The sensitivity can be used to estimate the available transfer capability of the study transfer and to predict the change region of the available transfer capability when the node power changed. Practical system analysis verified the proposed algorithm.
