Bridging from Kuramoto-like Networks to Real Power Grids: Lossy Grids, Voltage Regulation and Implementing Inverter Units — Katrin Schmietendorf1, Joachim Peinke1, and •Oliver Kamps2 — 1ForWind and Institute of Physics, Carl von Ossietzky Universität Oldenburg, Oldenburg, Germany — 2Center for Nonlinear Science, Westfälische Wilhelms-Universität Münster, Münster, Germany
Kuramoto-like models of electric power grids give insights into power system dynamics on the short-term scale in terms of self-organized synchronization. From the applicational viewpoint, the most current issues in power system analysis concern grid decentralization and increasing feed-in fluctuations induced by renewables. In order to address these topics, certain complements to the basic Kuramoto approach have to be taken into account. We investigate three supplements, which are particularly relevant for the integration of renewable energy plants on the distribution grid level: (i) transferlosses due to non-zero line conductance on the low and medium voltage levels, (ii) local voltage regulation by means of a proportional controller, and (iii) different approaches on implementing inverter units into the Kuramoto-like framework. In this talk we present the implications of these model extensions on different aspects of system stability and power quality.
