The present application relates to the technical field of power
system planning evaluation, and more particularly to a method and
system for dynamic evaluation of
energy storage based on
scenario joint debugging and risk early warning, the method comprising: constructing an evaluation
index system; obtaining original index data of the
energy storage technology to be evaluated under standard working conditions and performing dimensionless
processing; calculating the first weight of each evaluation index using a
grey correlation degree
analysis method, calculating the second weight of each evaluation index using an
entropy weight method, and obtaining a basic fusion weight by fusion; determining a
scenario correction coefficient based on the demand proportion of grid
frequency modulation and ramp service, and performing a first dynamic correction on the original index data; determining an
environmental risk correction coefficient based on an
extreme temperature environment, and performing a second dynamic correction on the original index data; and performing weighted calculation on the original index data and the basic fusion weight, and outputting a comprehensive utility
score. Through the present application, the problems of lack of scene adaptability and
environmental risk early warning and the problem of
fuzzy data quantization in the existing
energy storage evaluation method are effectively solved.
