The forecast model is set up by using the relation of price and load based on analyzing the mechanism of the price and the chaotic feature of the price time sequence in Sichuan power grid of our country. This model can successfully forecast the price in the real time and the present power market of Sichuan power grid. The model can be used to forecast the system marginal price and‘price spike’forecast.
