A Comprehensive Method to Mitigate Forced Oscillations in Large Interconnected Power Grids
IEEE Access, 2021 Multiple severe forced oscillation events have recently been observed across the North American interconnections and around the world. These forced oscillations have caused power swings, limited power transfer capability, damaged equipment, and persisted

Survey on forced oscillations in power system
Journal of Modern Power Systems and Clean Energy, 2017 The oscillations in a power system can be categorized into free oscillations and forced oscillations. Many algorithms have been developed to estimate the modes of free oscillations in a power system.

Forced harmonic oscillations of the Euler-Bernoulli beam with resistance forces
Trudy Odesskogo Politehničeskogo Universiteta, 2015 The important issue in the oscillation theory is the study of resistance impact on oscillatory processes. Unlike the calculations of free oscillations, that reside in determination of natural frequencies and waveshapes and unlike the calculations of ...
