Electric Power Research Institute
• Founded in 1972 by the electricity
industry and regulatory community
to provide collaborative R&D to
serve the public.
• EPRI members generate
approximately 90% of the
electricity in the United States.
• 450+ members from more than 30
countries.
• International members from
Europe, Asia and the Americas
contribute to the research and
development knowledge base.
The Power System – Looking Forward

frequency
• Provide safety by protecting from
unintentional islanding
• Disconnect from grid based on
over/under voltage/frequency
DC Power
Smart Inverter Functionality
• Voltage support
• Frequency support
• Fault Ride-Through (FRT)
• Communication with grid
