考虑负荷率和成本性态的容量成本分摊模型研究

Research on capacity cost allocation model considering load rate and cost behavior

针对我国现有输配电价中容量电费占比较低,固定成本不能完全回收,以及未考虑负荷率的问题,将负荷率电价应用到输配电价中,通过对输配电成本分析,阐述利用BARY曲线分摊容量成本的合理性,充分考虑用户的负荷特性,将用户通过聚类方法进行分档,将分段回归直线法作为确定容量成本在基本电价和电量电价的分摊比例的技术手段,提出了基于BARY曲线—分段回归直线法的容量成本分摊模型,通过实证分析,证明了该模型的合理性,在不同负荷率用户间分摊的公平性以及其定价的可行性。

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 ap⁃plied 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 meth⁃od,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 mod⁃el 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.
