Abstract
In this work, a comparison between aggregate (DER_A) and detailed (DER_D) models of distributed energy resources is presented. We evaluate the accuracy of aggregate representations of small-scale units as seen from the transmission network. The comparison focuses on the behavior of the tripping logic according to the ride-through characteristics. The simulations take into account the response of old and newer inverters during large disturbances in the bulk power system. The paper demonstrates that an aggregate model may fail to represent the response of hundreds or thousands of small-scale units. Hence, new aggregate models should account for the limitations identified in this work.
