Abstract
Aggregation of PV power plants can mitigate electricity demand as well as reduce consumption of fossil fuels. Due to high penetration of roof-top PV power into the Australian electricity market, utility planners and grid operators have to deal with short time variability of output power which can be a potential limiting factor in deploying PV systems. In this Paper, PV variability between different large cities will be analysed due to large there size and various climatic zones within Australia. In order to examine the smoothing effect of geographically distributed roof-top plants, output electricity data of five (05) minutes resolution for 200 sites are analysed. A significant smoothing effect are observed compare to a single site but it depends on the number of aggregated roof-top PV plants and relative correlation between them. Overall PV variability and the amount of smoothing are not the same in all cities within Australia.
