Evaluation on source-load matching based on equipment utilization efficiency of distribution network
In order to quickly and effectively evaluate the change of equipment utilization rate of grid-connected PV and enrich the extant source-load matching evaluation index system,a set of source-load matching evaluation methods considering equipment utilization rate of distribution network is established.First,a source-load matching evaluation model including fluctuation matching degree,power matching degree,consumption matching degree and load offset degree is constructed by analyzing distributed PV and load characteristics and equipment utilization indexes.Second,the indexes are assigned by pull-out grade method and a comprehensive score of source-load matching is obtained,and then the degree of impact of distributed PV grid connection on equipment utilization is directly judged based on comprehensive results.Finally,a case study on efficiency of equipment utilization in an industrial zone in Jiangsu province is carried out to verify the validity and reasonability of the source-load matching evaluation model.
