Impact of heterogeneities in power generation and transmission line admittances on power grid stability — •Matthias Wolff, Pedro Lind, and Philipp Maass — Universität Osnabrück, Fachbereich Physik, Barbarastraße 7, 49076 Osnabrück, Germany

In theoretical studies, power grids are often investigated assuming topological simplifications, namely neglecting the heterogeneous features of transmission lines and generators. These grid heterogeneities, however, play an important role and need to be taken into account to predict critical states for failure. We analyze their impact on the grid stability based on the dynamical equations for the voltage phase angles and frequencies in the synchronous machine model [1], which we apply to an IEEE test grid. It is shown that disregarding heterogeneities can lead to biased estimates of the grid stability [2]. This conclusion is drawn by comparing the stability of the heterogeneous IEEE test grid with a partially and fully homogenized version of this network.
