    Abstract

    Recently, in the process of deregulation, the fast evaluation of accurate ATC of a tie-line has become a more important problem from the point of view of the effective use of networks. Therefore, we propose an efficient calculation method for ATC with transient stability constraints. In this paper, we first focus our attention on characteristics of ATC and reduce the calculation time drastically by doing so. Secondly, we propose a new index for finding critical cases quickly using a transient energy function, and also propose an ATC calculation method by using the relationship between an increment of tie-line power flow and CCTs (critical clearing times). CCT is calculated by using the RIDGE theory. We confirm the validity of the proposed approach by running simulations using an IEEJ EAST 10 machine 47 bus system.
