摘　　要：针对我国省级电网现有输配电价中容量电费占比比较低,固定成本难以回收问题,研究新型电力系统建设背景下输配电电价体系问题。梳理了国外比较有代表性的英国、美国、法国等在完全电力市场环境下输配电电价体系,总结其特点和规律。在此基础上,结合构建新型电力系统的发展需求,分析构建以容量电价为基础的输配电价新体系的必要性,并以2021年度某省11个地级市大工业用户的电量数据为例,测算以容量电价为主的输配电价水平。测算结果表明,若实行容量电价,即使大量光伏并网,导致负荷水平下降,输配电成本仍然能够足额回收,对于我国省级电网输配电定价机制的设计具有参考意义。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 Chinas’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.
