s3-1, acquiring energy user amount screening data through an energy screening parameter H, obtaining the use sum of predicted theoretical digital energy user data and actual digital energy user data, and pre-estimating the distribution amount of the theoretical digital energy user data and the actual digital energy user data;
s3-2, in order to intelligently distribute corresponding theoretical digital energy user data and actual digital energy user data, calculating the energy distribution quota through a distribution model, wherein the model is as follows:
by judging whether the theoretical digital energy distribution quota q and the actual digital energy distribution quota v are larger than 0, U is the attenuation weight of the usage of the energy user, and W is a prediction function of the usage of the energy user; current theoretical digital energy distribution quota qiAnd the next stage of allocating credit qi+1(ii) a Current actual digital energy distribution quota vjAnd the next stage of allocating the amount vj+1。
