In modern power systems, increased loading or severe contingencies often lead to situation where system no longer remains in secure operating region. Under these situations, it is primary duty of power system operator to make the power system operate in secure region by applying suitable control actions. Any delay or unavailability in control action will make the system unstable. Due to the advancement in high power electronics, FACTS devices can play a major role in power system security enhancement. However, due to high capital investment, it is necessary to locate these devices at optimal location in the power system.
