With regard to the ongoing changes in modern power systems towards increasingly decentralised systems, the coordination of generation assets and the corresponding dependency on Information and Communication Technology (ICT) becomes highly relevant. This work demonstrates the impact of varying ICT latency on the control and the behaviour of Distributed Energy Resources (DERs) in an exemplary medium voltage grid. Thereby, the focus is on the settling time, the overshooting and the stability of the active power flow control between the interface of the medium and high voltage grid. Furthermore, this work describes a general method to simplify and analyse the stability of distribution networks with high DER-penetration, especially their sensitivity towards communication latency between the network controller and the decentralised assets.
