Understanding Power System Dynamics with High Levels of Grid-forming inverters

Overview

There is a lack of understanding of the modelling and control of grid-forming inverters in the system, leading to major delays in new renewable generators being able to connect to the network.

This project aims to address this issue by:
1. Developing an efficient way of modelling the grid-forming inverters and associated controls to provide an effective way to identify their impact on the network and improve hosting capacity.
2. Obtaining an understanding of the effect of high usage grid-forming inverters on the connection impedances (weak vs strong grids) and the impact of the dynamics of phase-locked loops.

Researchers from QUT and Curtin University will work with industry partners including Powerlink to investigate this issue and identify a solution that will provide a path for optimising network performance and allow more renewables into the grid.
