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.
