The invention discloses a peak electricity price making method based on a load transfer rate model, and the method comprises the steps: making clear an original time-of-use electricity price policy; building the load transfer rate model after the enforcement of the peak electricity price; building a load fitting model according to the load transfer rate model; carrying out the fitting of the parameters of the load transfer rate model according to the load transfer rate model and the load fitting model; taking the reduction of a monthly peak load and the maximum peak-valley difference of each month as the target, and making the optimal peak electricity price. According to the invention, the optimal peak electricity price is made based on the load transfer rate model, and the monthly peak load and the maximum peak-valley difference of each month are reduced. The specific peak electricity price is made according to the monthly load characteristics, and the method irons out the defects of unidirectional pricing.
