This presentation looks at modelling undertaken as part of the GREEN Grid project to understand the impact of system inertia during contingencies, and variability on frequency quality. It also looks at the dispatch of generation as more wind generation enters the power system. The presentation will first introduce a model of the grid, constructed to understand the impact of variable renewable generation on frequency, and the response of governor systems, especially hydro governors. Then look at a dispatch model of the grid, to understand how more wind generation might affect the utilisation of the remaining thermal stations and hydro generators. Results from the model will be presented, showing the performance on steady state frequency and during a contingency, as wind generation increases from the current level to over 3,000 MW.


Josh Schipper is a PhD student at the University of Canterbury, EPECentre, with the GREEN Grid Project. He is researching in the area power system stability, and the impacts of variable renewable energy (VRE) on power system security. He completed his Bachelors of Engineering, Electrical and Electronic, at the University of Canterbury with First Class Honours in 2013. He is passionate about how complex systems are designed and maintained in an efficient manner, within the complex decision processes of a deregulated industry, so as to benefit of the general welfare of the country.
