Title: Towards effective decentral stability certificates for power grids - The case of directed networks.
Speaker:  Frank Hellmann, Potsdam Institute for Climate Impact Research
Date & Time: June 4th, 16:15-16:45
Location: Seminar Room M 3170-73 in the M-building, LTH
 

Abstract: I will show that complex oscillator models can effectively capture (much of) the dynamics of future inverter dominated power grids. If the lines connecting them are lossless (or a rotation of reference frame can make them appear so), small-phase arguments provide for effective decentral stability conditions. The general case corresponds to a directed network with asymmetric coupling strength. I show that asymmetry can be captured as a phase perturbation to the numerical range of the coupling, and that the magnitude of this perturbation can be estimated.
