What challenges do isolated grids face?
Isolated grids such as islands, remote communities and remote industrial operations are typically cut off from larger grid infrastructure and therefore face unique challenges. They are often dependent on expensive liquid fossil-fueled generators for electricity supply.
Should Ocean Energy be integrated with other sources?
The most relevant outcomes underscore the advantages arising from the integration of ocean energies, namely, wave and tidal stream, in contrast to a system with other sources, particularly a system exclusively dependent on offshore wind.
What are NREL microgrids?
Microgrids can connect and disconnect from the grid and operate in grid-connected or island mode, which can result in improved customer reliability, cost reduction, and resilience to grid disturbances. Learn more about NREL's microgrids.
