On Stability of Automatic Generation Control [PDF]
2021 55th Annual Conference on Information Sciences and Systems (CISS), 2021 Automatic generation control (AGC) is one of the oldest and most important feedback control systems in large-scale interconnected power grids, yet no general and rigorous closed-loop stability analysis is readily available in the literature. We show in this talk how control-theoretic tools can be leveraged to perform a rigorous nonlinear dynamic ...
