The Analysis and Improvement of the Price Forecast Model Based on Fractal Theory

This paper discusses the basic principle of the fractal theory and the basic thinking of how to use it to forecast the electricity price, then build electricity price forecasting model and make a analysis on the prediction error to put forward improvement. Before the application of fractal mode in the price forecast field, there is a need to do R/S analysis of the data series to derive its index Hurst; And in forecast process, use variable dimension fractal parameters calculated by curve fitting technique instead of constant dimension fractal parameters.
