The National Development and Reform Commission has recently issued the provincial-level transmission and distribution tariffs for the third regulatory period and adjusted the scope of the two-part tariff implementation

granting eligible users the choice to adopt either a single flat-rate tariff or a two-part tariff pricing strategy. However

the selection of a pricing strategy that is more economically viable has become a challenge for electricity consumers. For this

the key factors influencing the selection of pricing strategies for users based on the current transmission and distribution tariffs and relevant electricity cost calculation rules are analyzed. By defining relevant parameters as variables and calculating the economic critical curve of pricing strategies based on the existing transmission and distribution tariffs

a model for comparing and selecting pricing strategies for transmission and distribution tariffs is constructed. The model is validated using typical user scenarios

providing a feasible solution for users to scientifically and rationally choose pricing strategies for transmission and distribution tariffs.
