Abstract
The next generation of electrical distribution systems (EDSs), with increasing penetration of distributed generation resources (DERs), represent complex energy systems with multiple functionalities. One of those functionalities is to improve the resiliency through formation of a microgrid. An ideal microgrid is capable of seamless transition from grid-tied to island state of operation. However, microgrid protection is one of the challenges faced by utilities. Since each EDS may have unique characteristics, overcoming this challenge requires an accurate modeling and simulation tool. In this paper an analytical tool is presented to assist utilities protection engineers in investigating the effectiveness of microgrid protection schemes. The tool uses raw data from utilities' existing database and generate accurate model of the EDS. The model can be used as a plug-and-play platform for different types of protection analysis. Simulation results of a real case study show the accuracy and functionality of the tool.
