Comprehensive Evaluation Method for Thermal Power Unit Flexibility Based on Data-driven and Its Application
摘要
Abstract
Sensing the flexible supply capacity of thermal power units actively is of great significance in promoting new energy consumption and enabling flexible dispatching of power grid.In this paper,a comprehensive evaluation method for thermal power unit flexibility based on data-drive was pro-posed.Firstly,flexibility,responsiveness,economy and envir-onmental protection were selected as evaluation indexes,and the evaluation factors of each index were defined.Secondly,a significant volume of operating data were utilized to obtain the characterization values of each evaluation factor within the daily operation interval of the unit through fuzzy c-means clus-tering algorithm and polynomial fitting.Meanwhile,the quant-ization of each evaluation factor was achieved by a weighted integral mean method.Finally,the entropy weight method and subjective assignment method were combined to determine the weight of each evaluation index,thereby realizing comprehens-ive evaluation of thermal power unit flexibility.An instance was taken to verify the effectiveness of the proposed method.关键词
