Aiming at the low proportion of capacity electricity price in existing transmission and distribution price in China’s provincial power grid

and the difficulty of recovering fixed costs in China’s provincial power grid

the problem of transmission and distribution pricing system is studied under the background of constructing a new power system in China’s provincial power grid. Typical transmission and distribution electricity pricing systems of Britain

the United States

and France under the complete electricity market environment are sorted out

and their characteristics and laws are summarized. Combined with the development needs of China’s provincial power grid to construct a new power system on this basis

the necessity of building a new transmission and distribution pricing system based on capacity electricity price is analyzed

and the electricity data of large industrial users in 11 prefecture-level cities of a province of China in 2021 is taken as an example to calculate the transmission and distribution price based on capacity electricity price. The results show that if the capacity electricity price is implemented

the transmission and distribution cost can be fully recovered even if large amount of PV is connected to the grid and load level drops

which has reference significance for the design of transmission and distribution pricing mechanism in China’s provincial power grid.
