The Interline Power Flow Controller (IPFC) is one of the latest generation Flexible AC Transmission Systems (FACTS) controller used to control power flows of multiple transmission lines. In recent years, power demand has increased substantially while the expansion of power generation and transmission. It has been severely limited due to limited resources and environmental limitations. Flexible AC Transmission Systems (FACTSs) controllers have been mainly used for solving various power system steady state control problems. Interline power flow controller is a versatile device can be used to control power flows of a multi-line system or sub-networks.
