University PMU Network: Source of Synchronized Phasor Measurements from Nordic Grid
• Each partner university deployed a PMU with a local PDC
• PMUs from SEL, ABB or the NI-‐cRIO
• PDC from SEL • Distributed Architecture
instead of Centralized Architecture (Single PDC)
• Advantage: Reliability, Local Archiving

Residential Load Industry load Reducible load
• The Icelandic power system is heavily loaded. – Idea: Control the Load in Aluminum smelters in the systems
for fault cases using PMU measurements.
Research Plan
• Develop Load Control Algorithm
• Test using the two area Kundur system. – In RT-SIL – In RT-HIL
• Deploy load control algorithm in an external controller, NI-cRIO (Compact Reconfigurable I/O Controller).
• Adapt the load control algorithm with different synchrophasor measurements (e.g. Voltage magnitude, voltage angle difference etc.)
