The invention discloses a new energy power generation grid-connection comprehensive peak regulation capacity assessment model based on demand side responses. The building processes of the model include the steps of (1) building a comprehensive peak regulation capacity assessment technology platform, wherein the comprehensive peak regulation capacity assessment technology platform is used for achieving acquisition, collection and calculation of peak regulation related data of the whole network, (2) building a peak regulation capacity index system, (3) building indexes related to specific peak regulation capacity and carrying out index statistics or calculation, and (4) on the basis of the peak regulation capacity index system, substituting the specific peak regulation capacity related indexes obtained in the step (3) to form the new energy power generation grid-connection comprehensive peak regulation capacity assessment model based on the demand side responses. The new energy power generation grid-connection comprehensive peak regulation capacity assessment model based on the demand side responses can overcome the defects that in the prior art, wind power output is poor in stability, high in peak regulation pressure and the like, and has the advantages of being good in stability of wind power output and low in peak regulation pressure.
