Abstract :
This paper discusses the application of high voltage power electronics (FACTS) for enhancing system stability in the main grid of Southern Norway. General aspects of application of FACTS in the Norwegian power system is discussed. A decentralized control scheme is applied to the control of a FACTS device. Case studies with a simplified model of the South Nonwegian grid are presented to illustrate the dynamic behaviour of the power system including HVDC transmissions and FACTS for various load conditions. The results indicate that TCSC (thyristor controlled series compensator) could be used to redispatch the power flow on tie lines and prevent synchronization problems after major disturbances in the South Norwegian main grid
