Grid-Transportation Integrated Energy Systems
As electric vehicle (EV) adoption rapidly increases, our power systems must evolve to incorporate vehicle charging and leverage these assets for improved grid and transportation performance.
NREL takes a wholistic approach to grid-transportation integrated energy systems to evaluate the impacts and opportunities of each type of charging, distributed energy resource, and grid asset. Our projects examine the effects of EV charging loads on the grid and explore how we can minimize the costs of grid integration and leverage EV charging to improve grid resilience and reliability.
