Project Summary

This project will deploy advanced technologies and methods to support operations that enhance grid resiliency in Cordova, Alaska under harsh weather, cyber-threats, and dynamic grid conditions. The deployment will use multiple networked microgrids, energy storage— including pumped storage hydropower—and early-stage grid technologies. This project introduces the concept of resilience-by-design, i.e., incorporating a cybersecure resilience framework with real-time sensing and controls at the design stage. This project was awarded under the U.S. Department of Energy’s Resilient Distribution Systems Lab Call, which seeks to develop and validate innovative approaches to enhance the resiliency of distribution systems, including microgrids, with high penetration of clean distributed energy resources.

Opportunities

Cordova’s previous energy efficiency and conservation projects have helped reduce use of costly diesel fuel and associated environmental impacts. However, like many microgrids, Cordova’s microgrid lacks any advanced sensing, smart reconfiguration, or energy storage with the capability to operate as multiple networked microgrids. This makes the city’s power supply vulnerable under conditions of harsh weather, dynamic seasonal loads, and, as with all communities, the increasing threat of cyberattacks. Resiliency-enhanced operation is necessary for modernizing Cordova’s microgrid and for accelerating the adoption of cyber-resilient microgrids in other locations.

Impacts
  • Field validation will minimize the deployment risk of modern power and cyber technologies.
  • Field data will provide insights into practical use of resilience metrics.
  • Cordova will gain a more resilient and secure grid with enhanced energy storage that reduces the need for diesel fuel.
  • This project will enable the Alaska Village Electric Cooperative to operate its 58 dispersed village communities as loosely-networked microgrids in coordination with larger utilities in Fairbanks and Anchorage.
  • This project will improve planning and energy resiliency in Alaska.
  • Field validation will minimize the deployment risk of modern power and cyber technologies.
  • Field data will provide insights into the practical use of resilience metrics.
  • By disseminating information from this project to electric cooperatives across the United States, this project will help improve resiliency across the nation.
Actions
  • Model and test the design and operation of the cyber-resilient microgrid through linked testbeds at U.S. Department of Energy laboratories using a digital, real-time simulation of the existing Cordova microgrid.
  • Simulation-based testing of pumped storage hydropower as part of microgrids under various dynamic seasonal conditions.
  • Deploy and validate the multiple-networked microgrids in Cordova.
  • Use zonal approaches in multiple loosely and tightly networked microgrids to increase the resilience and resources on the grid.
  • Provide upgrades and modifications through multiple networked microgrids, through micro-phasor-measurement-unit-based sensing, and by coordinating energy storage.
  • Economic analysis of design configurations and technologies for pumped storage hydropower.
  • Disseminate the lessons and information from this project to more than 800 electric cooperatives across the United States.
