应用PCA-C2R模型综合评判电网规划方案

电网规划方案的综合评判是一项复杂的决策性工作,同时也是一个解决不确定性问题的过程。将数据包络分析中的C2R模型与主成分分析法相结合,构建PCA-C2R模型,并建立了一套完整的电网规划方案综合决策方法,对电网规划方案进行综合评判。根据本文给出的电网规划方案综合评判流程与综合决策方法对一个实际的电网规划实例进行了分析计算,得到的结果与区间层次法和模糊层次法的结果一致。相比之下,本文建立的方法计算过程更加简便,更具客观性,是一种评判电网规划方案的适用方法。

Comprehensive evaluation of power system planning based on PCA-C~2R model

There is an associated complex problem in the procedure of comprehensive evaluation of power system planning. This paper first combines the C2R model, which is the basic model of the DEA method, with the PCA method to create the PCA-C2R model. Meanwhile, an integrated methodology of comprehensive evaluation is introduced. In a practical power system planning case, the same result is obtained by using PCA-C2R as other methods applied in comprehensive evaluation. By comparison, the whole theory proposed in this paper is much clearer and more objective, with simple and convenient calculation.
