Fault-tolerant wide-area control for power oscillation damping [PDF]
2012 IEEE Power and Energy Society General Meeting, 2012 In this paper, the effectiveness of using both local and remote (wide-area) feedback signals for power oscillation damping (POD) controllers is shown. However, the challenge is to guarantee a minimum level of dynamic performance with only the local signal following sudden loss of remote signals. A case study on the Nordic equivalent system is presented
