| 摘 要： | 为了提高电价预测的准确性,提出一种基于相似搜索和RBF神经网络的短期电价预测的方法。采用相似搜索原理来生成神经网络的训练集和输入矩阵,并运用MATLAB7.0中的神经网络工具来实现该模型。采用澳大利亚维多利亚电力市场2002年1月1日至3月17日共75天数据进行了实验分析,对3月11日～17日的各时段电价进行了预测,通过比较验证了本文方法的有效性。

| Abstract: | To improve the accuracy of electricity price forecasting,the various methods used in the short-term forecasting are analyzed and compared.A method for short-term electricity price forecasting is proposed based on analogue search and RBF neural network.The mathematical model based on analogue search is realized by the neural network toolbar in Matlab 7.0.The example of forecasting historical data is analyzed by using data from January1 to March17 of 2002 of Victoria power market.Compared with the results of forecasting of the price from 3.11 to 3.17,it shows that this method is effective. |
