Abstract

An advanced distribution management system (ADMS) is a software platform that supports grid management and decision support applications to address the growing operational challenges faced by power distribution systems to ensure reliable, resilient, and economic operations. In this paper, a fault location, isolation, and restoration (FLISR) application is developed and integrated with an open-source standards-based platform for ADMS application development viz. GridAPPS-D, developed by Pacific Northwest National Laboratory (PNNL). Also, a new distribution system restoration (DSR) algorithm, an integral part of the FLISR application, is proposed that utilizes backup feeders and distributed generators (along with intentional islanding features) to restore critical loads. The proposed application is developed in python and is tested on a modified IEEE 8500-node test system using the GridAPPS-D platform. The successful deployment of the FLISR application on the GridAPPS-D platform provides a proof-of-concept for the adoption of new and advanced ADMS applications to support future power distribution systems.

Highlights

The electric power distribution system is mired with unprecedented challenges due to an increase in severe weather events leading to prolonged outages, stricter regulatory requirements for increased reliability and resilience levels, and growing penetrations of distributed energy resources (DERs) [1]
It is worth mentioning that the Advanced Metering Infrastructure (AMI) reading and Interactive voice response systems (IVR) can be used in conjunction with the proposed approach to improve the performance of the fault location algorithm
To validate the proposed FLISR application, we had the following three requirements from the test system; (1) it should be supplied by multiple substations/feeders that can serve as backup feeders during the restoration process, (2) the system should be sufficiently large with numerous tie- and sectionalizing switches with a large number of possible reconfiguration options; and (3) it should include DERs to provide intentional islanding capabilities via grid-forming technologies in order to support the critical loads

Summary

Introduction

The electric power distribution system is mired with unprecedented challenges due to an increase in severe weather events leading to prolonged outages, stricter regulatory requirements for increased reliability and resilience levels, and growing penetrations of distributed energy resources (DERs) [1]. This motivates the need for a sophisticated operational platform that can support advanced applications to manage distribution systems operations, especially during stressed conditions. This work aims at developing an advanced FLISR application and integrating it within an ADMS environment
