[0002] At present, there are multiple methods for formulating transmission prices, but from the perspective of ideas, most of them first use the accounting cost method or marginal cost method to determine the annual income demand or the annual maximum allowable income of a certain transmission project in the transmission network. The traditional embedded cost method includes Stamp method, contract path method, etc., the source of the idea of ​​the stamp method and the billing method of the post and telecommunications system is an idea of ​​equal sharing. In a distribution network or power supply area, a stamp of face value is adopted, that is, a power transmission and distribution price; The contract path method assumes that when the power transmission and distribution business actually occurs, its electric energy can only flow through the continuous path stipulated in the contract, while the rest of the power grid in the power grid that is not specified in the contract is considered to have no impact. This method is only applicable to relatively large Price Calculation for Small-Scale Transmission and Distribution Networks

The multi-voltage level transmission and distribution network is different from the traditional power grid. The multi-voltage level transmission and distribution network has a lot of power loads, and the voltage levels of power users accessing the power grid are also different. The traditional transmission and distribution pricing method does not consider the utilization of low voltage levels. Efficiency factors cannot meet the particularity of transmission and distribution voltage levels and complex power supply relationships
