Site-Specific Evaluation of Microgrid Controller Using Controller and Power-Hardware-in-the-Loop
Microgrid assets are built by utilities to improve the resilience and reliability of segments of the distribution system. Controllers with advanced capabilities will operate and control these microgrids with diverse energy technologies, which vary from inverter-based photovoltaics...

Evaluation of Optimal Net Load Management in Microgrids Using Hardware-in-the-Loop Simulation
This paper presents the performance evaluation of a net load management (NLM) engine that balances load and generation in an isolated community to power a critical facility after a grid interruption event (e.g., the loss of a large generation unit). This NLM engine is particularly...

Cyber Security Primer for DER Vendors, Aggregators, and Grid Operators
This report provides an introduction to cyber security for distributed energy resources (DER)—such as photovoltaic (PV) inverters and energy storage systems (ESS). This material is motivated by the need to assist DER vendors, aggregators, grid operators, and broader PV industry ...

Post-Disaster Microgrid Formation for Enhanced Distribution System Resilience
This paper proposes a deep reinforcement learning (DRL) based approach for post-disaster critical load restoration in active distribution systems to form microgrids through network reconfiguration to minimize critical load curtailments. Distribution networks are represented as gra...

Identifying Best Performance Scenarios for Micro Nuclear Reactors During Grid Disruption
Micro Nuclear Reactors (MNRs) are an emerging innovation in nuclear technology as small, portable, and self-sufficient reactor units in the size of a standard 40-foot shipping container. An MNR functions as a “nuclear battery,” where each unit can power load capacities from 50...

Analysis of Microgrid Performance, Reliability, and Resilience (AMPeRRe) Computational Model: Novel Analytical Model to Forecast the Outcomes of Installation Power Grids
Federal facilities, industrial areas, academic campuses, and communities are working to incorporate greater renewable energy sources and energy storage in their power infrastructure. While renewable sources of energy can—and do—support several facilities, uncertainty still exi...

A Fast and Scalable Genetic Algorithm-Based Approach for Planning of Microgrids in Distribution Networks
As a result of climate change, extreme weather events are occurring more frequently and with increasing impact. This trend poses a significant challenge for distribution utilities and system operators to ensure that there is uninterrupted power supply to critical loads in their ne...

Managing Wildfire Risk and Promoting Equity through Optimal Configuration of Networked Microgrids
As climate change increases the risk of large-scale wildfires, wildfire ignitions from electric power lines are a growing concern. To mitigate the wildfire ignition risk, many electric utilities de-energize power lines to prevent electric faults and failures. These preemptive powe...

Demonstrating Distribution System Resiliency through Grid-Edge Microgrids, on a Multi-Site Networked Hardware-in-Loop Platform
With the increasing penetration of Distributed Energy Resources (DERs) at the grid-edge, power systems include more energy storage, remote switches, relays, voltage regulators, and other intelligent electronic devices (IED). Effective control of these grid-edge devices by using Ad...
