Demonstration Results

RDSI Secure Microgrid Demonstration Project

• Demonstrate – intentional islanding of a portion of the Utility

distribution system as a microgrid.– value of microgrids in peak load management.– advanced Cyber security solutions for microgrid

operations

Microgrid Resources

• Colorado State University – Engines and Energy Conversion Lab– 50-80 kW Load– 240 kW Diesel Generation

• City of Fort Collins – Northside Aztlan Recreation Center- 80-140 kW Load- 50 kW PV Generation

RDSI Microgrid Architecture

Some Issues And Questions
