The invention discloses a method for constructing a demand response scheduling evaluation system of a simulated peak-shaving unit. The method comprises: determining demand response scheduling evaluation time; taking the simulated peak-shaving unit as a target, and constructing the three-layer demand response scheduling evaluation system of the simulated peak-shaving unit from time dimension, capacity dimension and object dimension, wherein a first layer is a totality index, a second layer is a generality index, and a third layer is a specificity index; taking an ideal peak-shaving curve as an evaluation target, and constructing the demand response scheduling evaluation system of the simulated peak-shaving unit; and performing analysis on an index system with an evaluation method of an attribute interval recognition theory, and performing scheduling evaluation calculation. The demand response scheduling evaluation system of the simulated peak-shaving unit, constructed with the method, has comprehensiveness, independence, easy measurement property, flexibility and practicality, is helpful for more visually understanding a demand response scheduling result and a user response state in power grid scheduling, and provides a scientific and accurate basis for implementing demand response and settlement.
