TELKOMNIKA Indonesian Journal of Electrical Engineering, 2012 Unified power flow controllers (UPFCs) are FACTS devices which can fulfil multiple power-flow control objectives, such as the need for reactive shunt compensation, phase shifting and series compensation. However, as they are quite expensive, they are not widely used.
