OCC-Dynamic VAR Compensator

Breakthrough Technology

OCC-DVC is the first hardware enabled 3-phase DVC: ultra-fast, precise, reliable, and autonomous voltage regulation and voltage support with a simple user interface and small footprint. OCC-DVC leverages unique patented technology from Caltech & the University of California and the experience of the world-leading experts in power electronics. OCC-DVC enables local “reflexes” voltage support and wide-area voltage profile optimization. OCC-DVC is now in commercial service on the US grid.

Problems

• Limitation on renewable penetration on distribution feeders

• Equipment damage and process disruption within facilities

• Large-area blackouts and brownouts

• Grid losses from non-ideal grid-voltage profiles

• Instability of low-inertia micro-grids

• Costly maintenance of load tap changers (LTC) and switched capacitor banks (SCB)

Our Solution

• Increase renewable penetration by real-time grid voltage regulation

• Reduce equipment damage & disruption by stabilizing facility voltage

• Improve grid resilience by autonomous voltage regulation

• Improve grid efficiency by voltage-profile optimization
