LV Test Facility Uses

• Characterise single and multiple inverters in terms of:• Power quality• Transient behaviour• Anti-islanding performance• Performance

• Validate standard test methods (e.g. IEC62116) and design new approach for less than ideal condition e.g. noisy grid situations

• Help model development by providing real-life behaviour of physical units

• Develop advanced control methods to support the grid in high penetration scenarios.

7

LV Test Facility Planned Activities

• Validation of power quality inverter models

• Validation of anti-islanding models developed by University of Alberta

• Investigation of inverter behaviour in noisy grid situations (validate product standards in such conditions)

• Investigation of control strategies allowing inverters to perform active compensation of power quality issues
