Stability definitions and characterization of dynamic behavior in systems with high penetration of power electronic interfaced technologies

A task force set up jointly by the IEEE Power System Dynamic Performance Committee and the CIGRE Study Committee (SC) 38, currently SC C4 – System Technical Performance, had addressed in [1] the issue of stability definition and classification in power systems from a fundamental viewpoint and had closely examined the practical ramifications. At the time this document was published in 2004, the dynamic behavior of power systems was predominantly determined by the dynamic performance of synchronous generators and their controls as well as the dynamic performance of the loads. Consequently, [1] primarily dealt with fairly slow, electromechanical phenomena, typically present in power systems dominated by…
