摘要：

In Australia's National Electricity Market (NEM), generators provide their bids and re-bids in 0.5 hour trading intervals. Spot prices are determined in 5-minute periods by the intersection of the bids and power demand. Generator bids and re-bids are composed of power price determined in IO pricing bands and power offered in 0.5 hour intervals. Generator's behavior depends on several elements such as daily demand forecasted, maximum system capacity, the generation reserve predicted, transfer between the regions. The paper presents generator bids and re-bids based on two main aspects: distribution of prices and power offered in price bands. The functional relations for various days of a week, months and seasons for three main categories of power stations: thermal, gas and hydro are subject of the analysis is carried out for two main regions of the National Electricity Market (NEM) in Australia. Statistical distribution functions of typical bidding behavior are derived allowing the prediction of future pool prices.
