Real-Time Operation and Congestion Management Validation of Modular Power Flow Controller on a 150 kV Transmission System

IPTO, the Greek Transmission System Operator, describes their experience installing and testing modular power flow control technology. A post-contingency overload was identified and without any action would result in uneconomic dispatch of generation. Since this need was short-term, a mobile unit of modular power flow control was installed to resolve this constraint. Two representative use cases are presented – manual operation and automatic operation under an N-1 contingency condition. Results validate the device’s ability to redirect power flows to adjacent lines and effectively mitigate congestion.
