Some existing challenges with the integration of distributed energy resources (DER) and embedded microgrids are: congestion and voltage management, and fault protection issues. Until now, a limited amount of field experiments have been performed with embedded microgrids. This paper presents the Strijp-S living lab for embedded microgrid studies. The living lab consists of an urban distribution network with over 1000 consumers. For experimentation, advanced measurement equipment, automated switchgear and a high penetration of DER are installed in the living lab. Over the coming years the important challenges with the integration of DER and embedded microgrids will be addressed by universities and industrial partners.
