基于混沌理论及小波理论的短期负荷预测

Short-Term Load Forecasting Based on Chaos Theory and Wavelet Theory

分析了多种负荷预测的方法,着重分析了负荷的混沌特性与小波特性,同时分析了小波变换能够反应负荷的变化趋势与随机因素。利用Matlab工具,建立了基于小波理论与混沌理论相结合的负荷预测模型,并利用该模型对四川某地区短期电力负荷进行了有效的预测。

Many load forecasting methods are analyzed, and the emphasis of these analyses are the chaotic character and wavelet character of short - term load. Meanwhile, wavelet transform which can reflect the change trend and random factor in the load is analyzed. Using Matlab tool, load forecasting model based on the chaos theory and wavelet theory is established. And using this model the short - term load of an area in Sichuan province is forecasted.
