摘要

针对分类负荷在不同元胞内发展程度不同导致元胞负荷分布不均衡，从而影响空间负荷预测结果精度的问题，提出一种计及元胞发展程度的空间负荷预测方法。首先建立电力地理信息系统(GIS)，在电力GIS中生成元胞，并整合基础信息，其中包括用地信息、10 kV馈线的供电范围及分类负荷数据。其次求出总分类负荷密度的饱和值，再结合生长曲线揭示总分类负荷密度的发展规律。然后找到当前年各元胞内分类负荷密度在总分类负荷发展规律曲线上的位置，即为各元胞内分类负荷密度的发展程度。最后根据当前年元胞内各分类负荷密度的发展程度，结合总分类负荷密度发展规律曲线，确定目标年各元胞内分类负荷密度，再乘以元胞中每类负荷所对应的面积实现对元胞负荷值的预测。实例分析表明了该方法的正确性和有效性。

Abstract

For the problem of the classified loads in different cells with different development degrees that may cause the unbalanced cellular load distribution liable to lead to undesirable effects on the accuracy of spatial load forecasting results

a method of spatial load forecasting based on the development degree of cell load is proposed. Firstly

the electric power geographic information system is established

on which cells are generated. And the basic information is integrated including the land use information

10 kV feeder power supply area and classified load data. Secondly

the saturated load value of the total classified load density

and the development law of total classified load density are determined by the growth curve. Then the position each cell classified load density is in in the current year on the total classified load density development curve is found

as the development degree of the classified load density of each cell. Finally

the current year development degree and the total classified load density development law curve are used to forecast the size of the classified load density of each cell in the target year

then multiplied by the corresponding area

and the result is the cell load of the predicted value. An example analysis shows the correctness and the effectiveness of the method.
