Real-time testing of smart-WAMS for the monitoring of power oscillation

This chapter presents the real-time laboratory implementation/testing of smart wide-area monitoring system (smart-WAMS) algorithm. The smart-WAMS is the published approach to monitor power oscillations by the first two authors of this chapter. Smart-WAMS consumes the phasor measurement unit (PMU) signal and gives the accurate real-time information about the critical modes present in the system. However, in this chapter, the smart-WAMS is restructured to track the well-experienced critical mode in real time. The testing is done in national smart grid laboratory (NSGL), SINTEF, Norway under "ERIGrid transnational access" project awarded by European Union-Horizon 2020. The three power system networks are considered for testing and the first one is the "Nordic grid" system, the second is the offline "IEEE-39 bus system," and the last is the "North American SynchroPhasor Initiative (NASPI)" system. The real-time tracking of power oscillations is shown in video results.
