【摘要】 通过对混沌时间序列进行分析,找出了运用它进行电力系统负荷预测的关键因素:“取舍规则”、嵌入维数和延时的选取。笔者还建立了一种“取舍规则”,并运用它进行了实例分析,结果表明基于该“取舍规则”进行负荷预测的效果良好。更多还原

【Abstract】 Through the analysis of chaotic time series, two key factors used in power system load forecasting are found, i.e., the rule of acceptance and rejection and the selection of embedded dimensions and time delay. On this basis another kind of acceptance and rejection is proposed and applied in the analysis of practical examples. The analysis results show that the load forecasting based on the proposed rule of acceptance and rejection is more accurate.更多还原
