Background Information on the Power Quality Requirements in IEEE Std 1547-2018
This document provides context for the power quality requirements contained in IEEE Std 1547-2018. It explains why limits on voltage regulation, flicker, harmonics, and unintentional islanding were specified, and how distributed energy resources should comply. The guide discusses ...

An Innovative Energy Management System for Microgrids with Multiple Grid-Forming Inverters
As increasingly more grid-forming (GFM) inverter-based resources replace traditional fossil-fueled synchronous generators as the GFM sources in microgrids, the existing microgrid energy management systems (EMS) need to be updated to control and coordinate multiple GFM inverters th...

Using Energy Storage-Based Grid Forming Inverters for Operational Reserve in Hybrid Diesel Microgrids
Studies transient dynamics in a hybrid diesel microgrid during loss of wind generation and evaluates a transition from diesel spinning reserve to a battery energy storage system operating reserve using grid-forming inverters. Combines electromagnetic simulations with a power hardw...

Droop Control-Based Dispatch of an Islanded Microgrid with Multiple Grid-Forming Sources
Before rotating, fossil fuel-based, synchronous generators (SGs) are phased out, in line with renewable generation goals, grid-forming (GFM) inverters are expected to parallel SGs. Primary droop control allows GFM inverters to share power without communication; however, it is nece...

Experimental Characterization Test of a Grid-Forming Inverter for Microgrid Applications
Standardized experimental testing protocols for grid forming (GFM) inverters to ensure expected operation under both normal and contingency conditions do not exist. Such protocols increase the confidence of system owner/operators that an inverter deployed in a proposed system will...

Autonomous Microgrid Restoration Using Grid-Forming Inverters and Smart Circuit Breakers
The proliferation of distributed inverter-based resources (IBRs) raises the questions if these IBRs can be used to blackstart microgrids and distribution feeders after major outages. In this paper, we propose and evaluate an autonomous microgrid restoration concept using grid-for...

Power-Hardware-in-the-Loop Interfaces for Inverter-Based Microgrid Experiments Including Transitions
Microgrids continue to proliferate, particularly those that rely on inverter-based resources as the microgrid's voltage and frequency leader. Hardware-in-the-loop simulations can de-risk microgrid deployments, and therefore we need power hardware-in-the-loop (PHIL) interfaces for ...
