A demand electricity charge pricing optimization method considering demand response is provided, which includes the steps of taking the electricity charge and demand charge of two-part charge as independent variables, using the constant temperature load model to estimate the customer income, regulating the elasticity of customer value to make it suitable for different industries, setting the expected income of the power company, and estimating the reasonable two-part price through a game model based on Stackelberg competition between the regulated power company and its customers. Compared withconventional research results, results of the solution obtained by this method are that the demand charge is introduced, the pricing method is not only suitable for residents but also for industrialand commercial users, and the load rate can be effectively controlled.
