配电网空间负荷预测的核心问题是负荷密度指标的选取,目前选取负荷密度指标的方法一般难以满足实际工程中对精度的要求.引入AHP和TOPSIS法求取负荷密度指标,运用AHP法确定评价指标的权重,运用TOP-SIS法进行评价指标的规范化和排序计算,量化影响负荷密度指标的因素,选择负荷密度指标,并在此基础上采用相似度方法进行负荷密度的修正.将该种算法和模型应用于大量实际的工程项目,证明了该模型和算法能够快速计算出负荷密度指标,并且能够保持一定的精度,适用于工程实践中的空间负荷预测.
At present, the method of choosing load density index is generally difficult to meet the requirements of precision in the actual project.According to AHP and TOPSIS method, the load density index is obtained and the AHP method is used to determine the evaluation Using the TOP-SIS method to normalize and rank the evaluation indexes, quantify the factors that affect the load density index, select the load density index, and then use the similarity method to carry out the load density correction.This algorithm The model and its application to a large number of actual projects proves that the model and algorithm can quickly calculate the load density index and maintain a certain accuracy and is suitable for space load forecasting in engineering practice.
