The modern trend for consolidating electric power companies, even though the participants in these mergers may be not well connected electrically, suggests that technologies that permit power flow control in AC power networks may be favored for some applications. In this paper, the analysis of steady state power flow control in the presence of flexible AC transmission system devices (FACTS devices) is discussed. Objectives such as wheeling, line loading and unloading, ‘electronic fence’ methods to block power transfer, prevention of loop flows, and steady state security enhancement using FACTS are discussed. Newton-Raphson power flow studies for systems with FACTS devices are discussed. An example based on a large American power system is presented.
