Taking into account the complexity of influencing factors for the distributed energy supply system

the great variety of development scenarios

and lack of a quantitative method of investment planning and economy evaluation

a classified evaluation model of scenario competitiveness for the distributed energy supply system is developed. First

the three-level evaluation index system for scenario competition of the distributed energy supply system is built according to the soft and hard conditions of scenario competition. Practical evaluation indices are chosen on the basis of higher contribution rate of index and easier accessibility. A comprehensive classified system of the distributed supply energy system is then designed. The development of each type of scenario is analyzed

respectively. Finally

with the practical evaluation index as the input variable

the scenario competitiveness classified evaluation value as the output variable

the scenario competitiveness is calculated by using the hierarchical analytic process. Statistical data of distributed energy supply system in part of South China is taken as an example for analysis. The results further verify the effectiveness and adaptability of the model.This work is supported by National Natural Science Foundation of China(No. 51377060).
