Aiming at the existing distribution capacity in charge of low

fixed costs cannot be completely recycled

and not considering the problem of load rate

the rate of electricity is applied to the distribution of electricity

through the transmission and distribution cost analysis. The rationality of the allocation capacity cost using BARY curve is discussed

fully considering the load characteristics of the user

the user to step through clustering method

the piecewise regression straight line method for determine the capacity of the cost in the basic price and electricity price of share proportion of technical means

BARY curve is presented. The model of capacity cost allocation based on piecewise regression line method is proved to be reasonable

fair among users with different load rates and feasible in pricing through empirical analysis.
