Demonstration of Quasi-Static Time-Series Power Flow Studies for Islanded Three-Phase Microgrids

Abstract

The increasing penetration of distributed energy resources (DERs) in distribution systems led to an increase in interest in islanded microgrids. As a consequence, new simulation tools are required by utilities to leverage the benefits of these new system configurations. In this context, this work presents quasi-static time-series (QSTS) power flow studies using a method that utilizes the solution mechanism from OpenDSS. The system modeling and power flow solution are conducted using OpenDSS, simplifying the implementation of islanded microgrid studies. This paper implements and demonstrates the application of our proposed method in OpenDSS. Specifically, voltage regulation and power and energy balance studies are carried out on EPRI ckt 5, which is based on a real-world distribution feeder.
