This study presents the assumptions and strategies for practical implementation of dynamic mode decomposition approach in wide-area monitoring system Italian transmission operator, Terna. The procedure setup aims to detect poorly damped interarea oscillations power systems. Dynamic is a data-driven technique that has gained increasing attention different fields; proposed can both characterize oscillatory modes identify most influenced areas. results its operational experience monitoring. It focuses on main characteristics solutions identified reliably monitor electromechanical interconnected European system. Moreover, conditions issue an appropriate alarm case critical operating are described. effectiveness validated by application three studies: event short-circuit occurred previous years, 15-min time interval normal grid operation recorded March 2021.
