A comparison of wind integration metrics in the Tasmanian context

Large-scale integration of wind into power grids can have significant impact on the system stability. The maximum amount of wind generation a particular grid can sustain is a function of many variables such as load, generation dispatch, wind generation technology and the flow across interconnectors. There have been several attempts at determining a simple empirical criterion for determining this limit in real time. Some in particular are the Irish System Non Synchronous Penetration (SNSP) and the Tasmanian Rate of Change of Frequency criteria. This paper compares the application of these two metrics. The situations in which each metric gives better performance are analysed. Finally, the direct application of each metric to the Tasmanian context is analysed.
