基于元胞历史负荷数据的负荷密度指标法
A Load Density Index Method Based on Historical Data of Cell Load
摘要
Abstract
ABSTRACT:In existing methods to obtain load density index the mining of measured historical data is frequently neglected, or the non-uniform distribution of homogeneous loads is ignored. For this reason, a cell load historical data based load density index method is proposed. Through the load density of class I cell, the coordination coefficient of classified load density is determined, and according to the historical load of class I cell and the constraint relation among its power supply area, land use information and classified load densities the relation equations of cell load and classified load densities are established and the classified load density index is obtained by least square method. Using the obtained classified load density index of past years the load density in the target year can be predicted, and the load value of each class II cell is solved, thus the spatial load forecasting is implemented. The practicality and validity of the proposed method are verified by engineering example.关键词
