Abstract

The low voltage electricity network is a large distribution asset designed to deliver electricity to customers whilst maintaining voltage within statutory limits. Recent increases in solar photovoltaic connections have changed the way electricity flows through the network. Instead of flowing from generators, through transmission networks, through distribution networks and then to customers, electricity can now flow in either direction. This can cause voltage issues to customers.

This research project investigates the use of emerging low voltage regulation technologies to address performance issues on the LV network. The initial part of this project investigates four types of LV regulation opportunities, which are a Gridco Systems Inline Power Regulator (IPR), a distribution transformer with an on load tap changer, a transformer with electronic regulation and installing a Volt VAR regulator device.

The core component of this project assesses the Gridco Systems IPR as a viable means of addressing LV regulation problems as this device has been installed within the Energex network. Voltages were measured before and after the IPR was installed and the measured data compared to the modelled data.

There has also been a cost benefit analysis completed to ensure that this alternative is the most cost effective solution in these scenarios.

The results show that the IPR maintains the voltage within statutory limits and a tighter range than before the IPR was installed. The results also indicate that there is the ability to provide greater PV hosting capacity on the LV network. The field based trial will continue after this project is completed to ensure the device is suitable in all seasons for Australian conditions.
