This paper describes experience with modal estimation tools for monitoring oscillations in the ENTSO-E continental European power system. A brief description of the modal estimation tools and the wide-area monitoring system (WAM) used by Swissgrid is given. The response of the modal estimation tools is illustrated using recordings from actual events. Furthermore, main use cases for the information...
This paper gives a survey of two approaches applied to detection of critical power oscillations in electric power systems. The developed techniques are based on models identified in real-time from measured data. The resulting models yield the actual power system dynamics. They can be used for monitoring purposes as well as for design of stabilizing/damping controllers applied to any fast acting power...
