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