[caption id="attachment_4506" align="alignright" width="450"] Figure 1 South Australian power system[/caption] The South Australian (SA) power system exhibits one of the highest penetrations of asynchronous generation worldwide, with only one AC interconnector to a neighbouring power system. The installed asynchronous generation amounts to approximately 2 GW including two transmission connected battery energy storage systems (100 MW and 30 MW respectively). This is supplemented by approximately 900 MW of rooftop PV. The current average grid demand in SA is approximately 1400 MW with a minimum demand of 650 MW. The majority of asynchronous generation is relatively condensed in a small number of remote areas, whereas most synchronous generation and loads are in the…
