The present disclosure relates to a dynamic evaluation method and device for the peak regulation and
frequency modulation response capability of a battery swap
station based on two-
dimensional analysis. The method comprises: constructing a multi-working
condition evaluation index system for the peak regulation and
frequency modulation response capability of the battery swap
station, setting evaluation grades and
score thresholds according to the grid operation working condition; using a subjective and objective fusion
weight distribution method to calculate the comprehensive weights of static dimension indexes and dynamic dimension indexes respectively, and fusing by the product normalization method; calculating the closeness
score of the static dimension of the battery swap
station; constructing a dynamic response capability evaluation model based on the
grey correlation degree method to calculate the
grey correlation degree
score of the dynamic dimension of the battery swap station; weighting and fusing the static score and the dynamic score to obtain the comprehensive score of the peak regulation and
frequency modulation response capability of the battery swap station, and judging whether it meets the standard and participates in the priority according to the preset threshold. The present disclosure constructs a benchmark sequence consistent with the grid dispatching rules for different evaluation working conditions of the dynamic dimension, and improves the accuracy of the
grey correlation degree method in the dynamic dimension evaluation.
