Step 3: according to the obtained electricity consumption data, analysis can be carried out according to the resident house data, month electricity consumption data can be estimated for the resident house data, meanwhile, analysis is carried out for the industrial area house data, month electricity consumption data can be estimated for the industrial area house data, and summarizing statistics is carried out on the estimated data;
Step 4: and feeding back the estimated and counted electricity consumption data to the transformer substation to change the electricity generation plan.
