Abstract:This paper presented a new algorithm for the calculation of available transfer capability(ATC) of long transmission line interconnected power system.As the loadability of long lines is constrained by static stability limits of grid,this algorithm first deduces the line transfer stability limits in order to describe the problem of static stability limits efficiently and concisely and to set up a new ATC model of long transmission line interconnected power system.Based on the algorithm of imputation of an imp...
