Power Systems Integration Laboratory

The Power Systems Integration Laboratory or PSI Lab is located within the Energy Technology Facility on the University of Alaska Fairbanks campus and emulates an isolated hybrid-diesel grid at up to 500 kW of permanently installed capacity and potential capacity of several MW. The infrastructure of the lab facilitates integration testing with power levels and system architectures relevant to typical Alaska rural power plants — from generation to storage to distribution and control. It transforms a potentially chaotic field-testing environment into a continuously improving process for optimizing efficiencies. Operating on the same scale as an Alaskan village power system, the PSI lab has the ability to be modified for individual test scenarios and provide valuable data for researchers, communities policy makers, and industrial clients.
