Breakthrough Technology:
OCC-VAR leverages unique patented technology invented at Caltech & University of California and developed by the world leading power electronic experts under the sponsorship of U.S. Department of Energy. OCC-VAR is the first hardware-enabled 3-phase Reactive Power Supply with high reliability, extremely fast dynamics, and simple user interface, enabling reactive power compensation, voltage support, and/or power grid stabilization in real-time. OCC-VAR supplies reactive power wherever, whenever, and however on demand.

Problems:
• VAR is required to support real power transfer,
but long distance VAR delivery reduces transmission
capacity and causes power loss
• Fast load transients cause voltage flicker and sag
• Intermittency of renewables causes grid voltage
transients and must be curtailed
• High demand causes voltage collapse and large area
blackout

OCC Solution:
• Supply VAR locally to free up reactive occupied
capacity and minimize transmission losses
• Regulate the terminal voltage to maintain high power
quality
• Stabilize the grid against intermittency to increase
renewable penetration
• Support voltage, prevent blackout, and protect the
power grid and customers

OCC Benefits:
• Hardware enabled control –– ultrafast precise VAR on demand
• Simple user interface –– low maintenance & service
• Modular plug & play architecture –– scalable
• Long life design –– low logistics & installation cost
• Light weight –– minimum raw material usage, environmentally friendly
• Small size –– space saving
• ETL listed –– safe and high quality
• U.S. Department of Energy sponsored and awardwinning technology –– highly competitive

Sponsorship:
• OCC-VAR was developed under partial support of U.S. Department of Energy
