Modeling the dynamics of future power grids — •Raphael Kogler — Potsdam Institute for Climate Impact Research, Germany

An important aspect of tackling the problems posed by climate change is the transition from fossil-based and nuclear energy toward a greater share of renewable energy sources. For our power grids this means a gradual replacement of the conventional synchronous machines by converter-interfaced generation units.

While the dynamical behavior of synchronous machines is commonly modeled by the swing equation (the Kuramoto model with inertia), the dynamics of converter-interfaced units will be given by the specific control scheme applied to the converters. There are various proposals for such control schemes but no clear consensus as of yet.

However, as different as they appear, there are certain shared aspects when viewed in the context of complex amplitude oscillators. I discuss how the Stuart-Landau oscillator can serve as a paradigmatic model of such an oscillator and provide a basis for understanding the dynamics of future power grids.
