Impact of penetration of non-synchronous generators on power system dynamics

Due to the integration of Distributed Energy Resources (DERs), both non-synchronous generators and energy storage technologies, the dynamic behavior of power systems is changing. The extent of the impact is yet to be fully investigated and quantified. Proper models, suitable for large scale studies but also representing all the DER control and protection mechanisms that affect the dynamic behavior of individual components and the system as a whole are used in this study. The effect of DER location, penetration level and decommissioning of conventional generators is studied. A Monte Carlo approach is used to account for uncertainties resulting from different fault location, duration and loading of the system. The focus of the paper is to illustrate the effect of DERs on power system stability and dynamic signature.
