The Enhanced Binary-Single Machine Infinite bus Equivalent (Binary-SIME) method is an enhancement of the SIME method. It provides a robust and flexible approach to searching for the transient stability limits (TSLs) in a fully detailed model of a multi-machine power system. This paper describes the modular implementation of the Binary-SIME method with the PSS/E™ time domain simulation package. Extension to incorporate alternative search approaches is facilitated by the modular architecture. The Binary-SIME search implementation is applied to the IEEE simplified model of the Australian power system to search for power transfer limits (PTLs) and critical clearing times (CCTs). The Binary-SIME method is compared with the binary search method in the search for TSLs.
