dc.description.abstractPower oscillations are a growing concern among power system operators worldwide. Traditionally, the main countermeasure against dangerous power oscillations has been the installation of power system stabilizers (PSS). Essentially, the potential for inter-area power oscillations depends on the strength of the tie lines between different areas and the load on the ties. From a European perspective, with the anticipated integration of remote renewable energy sources such as offshore wind power from the North-sea region and solar power from southern Europe or Africa, we can expect the average transmission distances to grow and consequently also tie line flows. Unless tie lines are also reinforced we expect more oscillation events in the European grid in the future. From an operational point of view, it is of high priority to be able to estimate the damping of oscillatory modes reliably in real-time in order to take appropriate and timely measures in case damping becomes poor. Recent developments in wide-area phasor monitoring have resulted in a new power oscillation monitoring algorithm that uses multiple measurements from different locations in the grid. An equivalent system model of the power grid is estimated in real-time and based on this model, the damping and frequency as well the activity of oscillatory modes can be determined from ambient process variations. As basis for this, a wide-area measurement system (WAMS) can provide time synchronized signals from phasor measurement units (PMUs) that can measure voltage, current and frequency with adequate accuracy and resolution in time. This paper shows results from pilot operation of the new application at swissgrid, including recordings from an actual and representative event in the continental ENTSO-E interconnected power system. This example demonstrates the performance of the new application as well as provides information about the oscillatory modes present in the continental ENTSO-E system today. Furthermore, FACTS and HVDC systems can serve as powerful actuators to control inter-area oscillations, provided they are equipped with appropriate controller extensions. Particularly for the control and management of inter-area oscillations, remote measurements have proven useful. The paper outlines the technical aspects and suggests a design procedure for controller extensions based on local or remote measurement for the purpose of inter-area oscillation damping.de_CH
