基于委托-代理理论的负荷率可选择电价最优合约设计
摘要：首先以综合成本定价法为基础，分析了考虑负荷特性的不同电压等级用户的供电成本；在此基础上，应用经济学委托-代理理论，建立了考虑负荷率的两部制可选择电价委托-代理模型；经过严谨的数学推导给出了该制度安排问题的数学解析解，即求得最优合约函数，能够有效解决选择性定价中的逆向选择问题；算例验证表明该激励机制既能反映不同负荷率和电压等级用户的真实成本，实现公平定价，又能给予用户选择权并鼓励用户合理用电；且当选项数目为4-5项时，该套餐的定价效果能够接近完全非线性价格形式。
Abstract:Based on comprehensive cost pricing method and the power supply cost for power consumers in different voltage grades was analyzed while the load characteristics were considered. On this basis, applying the commission-agent theory in economics a commission-agent model, in which the two-part optional electricity price was considered, was established. By means of rigorous mathematical derivation a mathematical analytic solution for such an institutional arrangement problem, i.e., to obtain the optimal contract function that could effectively solve the adverse selection problem in the selective pricing, was given. Results of calculation example show that the proposed incentive mechanism can not only reflect real costs of electricity consumers in different voltage grades under different load rates to implement the fair pricing, but also can give the consumers the right of choice and encourage them rational electricity consumption, besides, when there are four or five options the pricing effect of such a package can be close to complete nonlinear price form
