Impacts of voltage transition from 240V to 230V voltage standard

Currently the Queensland Electricity Regulation requires voltages to be maintained within a variance of +/- 6% from the standard voltage of 240V. Consequently, distributors are required to ensure the quality of supply is maintained within these prescribed limits throughout its network. Increasing levels of Solar PV penetration are currently causing many networks to experience over-voltage issues. This study looks into the implications of transitioning to the 230V standard (AS61000.3.100) as a possible solution to resolving these over-voltage issues, with preliminary results suggest that transitioning to AS61000.3.100 would likely result in significant cost savings as well as reducing over-voltage issues experienced by customers.
