Microgrid in Cordova, Alaska, Is Model for Resilient, Local Energy

The city of Cordova, Alaska, is enhancing the resilience of its microgrid with support from DOE's Grid Modernization Lab Consortium—including Idaho National Laboratory, Sandia National Laboratories, and Pacific Northwest National Laboratory—and nine industry partners. The resilience-enhancing technologies include new energy storage; new controls for its hydropower resources; and a fleet of meters, sensors, and advanced zonal controls using smart metering infrastructure to manage recovery, improve resilience, and support the city's fishing economy by serving seasonal and critical loads. Using ARIES, Cordova validated its improved microgrid against plausible events, such as power loss from an earthquake or avalanche, allowing the local electric cooperative to observe and control the network with more precision. This is important for Cordova and indigenous communities throughout Alaska because microgrids are their last resort for energy, and controls make it easier to adapt during critical events.

Common Type of Wind Turbine Can Form the Grid—A Breakthrough for 100% Clean Energy

Type-3 wind turbines, one of the most-used wind technologies, can now supply baseline power to the grid without requiring fossil-fueled or other resources to set grid stability. Demonstrations with GE at ARIES showed that the wind turbine can provide the sort of fundamental power necessary to anchor the grid around stable frequencies and voltages. This makes it possible for wind turbines alone to form a grid, such as when disconnected from the larger grid or in high-renewable energy systems. This also opens new value streams for wind energy participating in power systems.

ARIES Adds Hydrogen to Hybrid Power Plant To Study Flexible Generation

Using ARIES, NREL and more than a dozen partners are exploring how renewable power plants can operate as a flexible energy source when paired with energy storage from hydrogen. The FlexPower project brings NREL together with other national laboratories (Idaho National Laboratory and Sandia National Laboratories) to develop a hybrid generation power plant enhanced with energy storage at NREL's Flatirons Campus. This electrons-to-molecules scheme is being evaluated in a Grid Modernization Initiative-funded project that will reduce costs via standardization and through the possibility of scaling up electrolyzer integration. Such hybrid power plants will accelerate the adoption of variable renewable energy and hydrogen storage by proving new value streams for these resources.

Digital Twin Will Demonstrate Resilient Microgrid Controls Before Deployment

NREL and partners are developing an advanced control architecture to improve microgrid resilience and reduce downtime after disturbances. Microgrids are key factors in strengthening grid resilience because they can disconnect from the traditional grid to operate autonomously and function as a grid resource for faster system response and recovery. With ARIES assets, the team will evaluate a new control architecture by connecting a physical microgrid to power system simulations. This unique digital twin approach replicates challenges faced by utilities managing microgrids, helping them evaluate and improve their resilience strategies and deal with increasingly extreme events. Partners include utilities, industry, universities, and a state government collaborating toward a workable architecture and example for community-scale microgrids.

Rapid and Robust Grid Recoveries Become Possible With Intelligent Algorithms

An NREL-supported Advanced Research Projects Agency-Energy (ARPA-E) project could fundamentally change how large grid outages are managed by demonstrating recoveries for critical infrastructure. Using algorithms built by the University of Minnesota and NREL, this new method identifies resources that can rapidly energize and sustain the grid for long periods of time. The multiple partners on this project will soon validate their "rapidly viable grid" design on ARIES assets, showing that the method works in a replica grid environment and preparing it for adoption where resilience is most needed on real energy systems.

International

The country of Lithuania is transitioning to 100% renewable energy, and to achieve this extraordinary goal, the government will use ARIES—the only platform able to integrate and validate all of its options for clean, safe, and equitable energy.

Similarly, utilities are relying on ARIES to deploy upcoming technologies—first on a risk-free replica grid with ARIES and then live. The Israel Electric Corp. is one example. The utility is collaborating with NREL to improve its power restoration and fault identification approach.


This is where energy alternatives come to life. The bold strategies being pursued by partners are within reach because of ARIES, where experiments are unconstrained by limits on power or computation and can push as far ahead as technology permits. With so many options to transform energy around the world, we look forward to what's ahead with ARIES.

NREL works with organizations—large and small—to expand the clean energy economy. You can partner with ARIES to accelerate renewable energy and energy-efficient solutions into practical applications. Watch for opportunities to work with us on the ARIES web page, or email us at ARIES@nrel.gov to discuss your project.
