Extending capability in Europe to make the precise measurements required for smart electricity grids
The power industry is transitioning to renewable sources of energy which tend to be locally distributed. To avoid instability, poor power quality and blackouts, precise measurements are required to ensure supply matches variable demand. Traceability of the volt and ampere to the SI quantum standard is offered by only a few National Metrology Institutes (NMIs) in Europe and to ensure the establishment of the interconnected grids required for secure, harmonised energy supplies this capability requires extending to other, developing, European NMIs.
The project will design and build a practical quantum power standard based on programmable Josephson voltage standards (PJVS) along with software for its operation. New methods for the measurement of electrical power using quantum systems will also be developed and validated. Outputs will be included in an open-source Quantum Power measurement System, available to the whole Metrology community, providing direct traceability of power measurements to the SI. At the project completion in 2023 these results will enhance European coordination and help provide the accurate measurements required for the stability of future electrical grids.
