基于模糊综合评判的负荷密度指标选取新方法

A Novel Fuzzy Comprehensive Evaluation Based Method to Select Load Density and Index

将模糊综合评判方法应用于电力负荷密度指标的选取。首先分析影响密度指标的各因素所占权重,然后对待定的密度指标进行模糊综合评判,最后根据评判结果对评判对象进行归类并选取相应的密度指标。该方法克服了以往通过简单类比或经验选取密度指标易造成主观随意性大、结果欠量化的问题,具有较强的科学性和实用价值。

The fuzzy comprehensive evaluation is applied to the selection of power load density and its index. Firstly, the weight in the impaction of each factor that impacts the density index is analyzed; then the fuzzy comprehensive evaluation for the undetermined density indices is carried out; finally based on the evaluation results the evaluated objects are classified and corresponding densities as well as their indices are selected. The proposed method is a practicable one that can remedy the defects of evident subjective arbitrariness in the selection of load density and its index by simplified analogy or experiences as well as the non-quantized selection results.
