摘要

It is widely acknowledged that demand response must play an increasingly important role in future electricity markets. This is as much due to increasing demand for air-conditioning as it is due to the changing sources of generation. In the National Electricity Market (NEM) in Australia, for just 3% of the year demand increases by 20%, or the equivalent of the generation from the two largest coal fired power stations combined. Over smaller regions and time intervals demand spikes are larger. Air-conditioning demand response takes advantage of a buildings inherent thermal storage to reduce electricity demand at peak times with no discernible impact on the indoor operating environment. Here we estimate the existing potential of commercial and residential air-conditioning systems to provide demand response across Australia. We use a top-down approach based on disaggregation of electricity substation half-hourly data. Results are that peak (i.e. 99.5th percentile) demand on the NEM could be reduced by up to 5.8% or 1.2 GW with the time of day at which the peak occurs delayed by approximately 2 hours. Based on the timing of the available capacity, both residential and commercial buildings are suited to providing air-conditioning demand response.
