A small but mighty team has made a significant contribution to the development of microgrid technology. By integrating two Nissan Leaf electric vehicles into a regional airport's energy system, they've not only reduced greenhouse gas emissions but also enhanced the airport's resilience in the face of grid outages.
The project, which began operating in 2021, features a 2.2 MW solar array, 8.9 MWh of battery storage, and a 300 KW net-metered solar system. The Nissan Leafs, one of which was purchased by the Humboldt County Aviation Division and the other provided by Nissan as part of a pilot program, serve as both electric vehicles and energy sources.
The cars are plugged into four bidirectional chargers on site, allowing them to feed excess power back into the grid or absorb it during outages. In islanded conditions โ where the airport is disconnected from the main grid โ the microgrid can still respond by sending solar energy to the Leafs if necessary or drawing energy from them to add to the main storage.
This innovative solution expands the capacity of the Redwood Coast Airport Microgrid, enabling it to power the airport during local grid outages and provide an additional clean energy resource for maintaining statewide grid stability. As David Carter, principal engineer at the Schatz Energy Research Center at Cal Poly Humboldt, noted, this project showcases "innovative Vehicle-to-Microgrid (V2M) technologies and demonstrates how EVs can support local energy needs and grid resilience."
While it may seem like a small step in the grand scheme of things, integrating electric vehicles into microgrids has significant implications for reducing emissions and improving grid stability. As the world transitions towards a more sustainable future, this type of technology will play an increasingly important role.
The development of bidirectional charging systems, such as those used at the Redwood Coast Airport Microgrid, is crucial in unlocking the full potential of electric vehicles. By enabling two-way energy transfer between cars and the grid, these systems can help stabilize the grid during outages and provide additional clean energy resources.
This project serves as a proof-of-concept for how electric vehicles can be used to support local energy needs and enhance grid resilience. As the technology continues to evolve, we can expect to see more innovative applications of V2G and other vehicle-to-grid technologies in the years to come.
