“…Transmission switching has been proposed as a corrective mechanism for problems such as over or under voltage violations, line overloading, and system security, see [2], [4], [11], [12], [21], [31]- [34]. Transmission switching can also be used to help reduce system losses, see [3] and [10], and it can be used as a congestion management tool as well, [13]. One potential setback of transmission switching is its impact on transient stability; however, [5] has shown that switching actions can actually help improve the transient stability of the network.…”
