Generation expansion planning in Queensland under rooftop photovoltaic penetration and gas market uncertainties

This paper investigates the impacts of rooftop photovoltaic (PV) penetration as well as gas market uncertainties on the generation planning decisions. These issues are paramount in the state of Queensland in Australia that has traditionally been reliant on coal based generation. A Generation Expansion Planning problem is used to evaluate alternative generation development scenarios for Queensland for the next decade. A scenario-based sensitivity analysis is also performed to assess the effects of load growth, gas price, carbon price, renewable energy target (RET) and rooftop PV uncertainties
