Investigation of integration option for Renewable Energy into existing energy infrastructure
In the medium to long term, ambitious mitigation policies will lead to an ever increasing share of renewable energy sources (RES) in total power production. Currently, wind and solar power are assumed to be the key technologies in this development. However, their production fluctuates greatly over time (depending on changing weather patterns – cluster III) and does not follow demand, and sites with high potential are often some distance from demand centres like cities. This temporal and geographical mismatch gives rise to a number of economic and technological challenges, which are subsumed as the process of "integration of RES" in existing energy systems. The PhD candidate will investigate the economic aspects of selected integration options, and will thus contribute to an understanding of the extent to which integration costs increase the total system costs of energy supply.
Roger has extensive experience in the fields of global carbon cycle, atmospheric chemistry and renewable energy system modelling. He currently works on a electicial energy system model for Australia with the goal of optimising the pathway to a low carbon economy. The model simulates power output from a broad range of technologies including wind, solar PV, solar CSP, hydro, wave and tidal, coal, gas geothermal amd biomass. The model also simulates transmission flows and the electricity market so that a comprehensive costing of different mixes of technologies can be made. The model is run in an optimisation loop such that many thousands of combinations can be tested so we can find the most cost effective system configuration.
