| 摘 要： | 分形插值方法的参数对插值的结果影响很大.在基于分形的电力系统负荷预测中,如果得不到合适的分形插值参数,将会影响到预测的精度.针对传统的分形插值方法很难确定分形参数,文章对基本的遗传算法进行了改进,并将其应用于分形插值的垂直尺度因子的寻优中,实现预测日负荷曲线的最佳拟合.算例结果表明,利用改进的遗传算法进行分形插值参数寻优的方法提高了负荷预测的精度.

| Abstract: | Parameters of fractal interpolation method have great influence on interpolation results.Without proper fractal interpolation parameters,the precision of power system load forecasting based on fractal method will be doubtful.According to the problem that traditional fractal interpolation method is hard to obtain proper fractal parameters,a modified genetic algorithm is proposed and applied to the optimization of vertical scaling factors of fractal interpolation, which realizes the optimal fitting of day loa... |
