基于城市用地性质的配网空间负荷预测研究

摘要

配电网规划与城市的用地性质息息相关.基于城市的用地性质进行负荷分区,并将其与负荷预测相结合,使之成为空间负荷预测中负荷密度预测的依据,能够提高负荷预测的精度,也因此在配电网规划中具有实用价值.针对实际规划中存在的样本数据充足和不足的情形,分别使用最小二乘法和相似搜索方法加以研究,使负荷密度预测有规可循,也是空间负荷预测的前提准备.%It is closely related between distribution networkplanning and the nature of the urban land-use property.Subarea load is calculated based on the property of the urban land,and combined with load forecasting,whichcan be used as a basis for load density forecasting of spatial load forecasting.It has practical value for improving the accuracy of load forecasting in distribution network planning.The least squares method and the similarity search method are used to study the situations of sufficient and insufficient sample datum in the actual planning,so that the load density prediction can follow the rules and be the prerequisite for the prediction of spatial load.
