基于基尼系数的电力网络投资分配模型及应用

将广泛应用于国民收入分配和环境治理领域的基尼系数引入电力网络投资分配方案设计中。首先,利用总资产回报率、未来给定时段内的预测售电量及投资售电比这3个指标, 在优先考虑效益（效率）的前提下, 综合确定电网公司未来的投资初始分配方案。然后, 选择容载比、可靠性等作为控制指标, 发展了基于基尼系数的投资分配模型, 并以投资初始分配方案为基础, 从提高分配公平性的角度优化确定最终的投资分配方案。最后, 对某省级电力网络进行实证研究, 证明所提投资分配模型的可行性。

A Gini Coefficient Based Investment Allocation Model for Power Networks and Its Application

This paper introduces the Gini coefficient widely used in the national income allocation and environmental governance into the investment allocation scheme design of power network. Firstly, we use three indexes including the return on total assets, future forecasted electricity consumption in a given period and the ratio between investment and electricity sale, to determine the initial allocation scheme of future investment in a given power network under the premise of preferentially considering the efficiency/benefits. Then, we choose capacity-load ratio, reliability and other control indexes to develop the investment allocation model based on the Gini coefficient. And we determine the final optimal investment allocation scheme from the perspective of improving the allocation fairness, based on the initial allocation scheme of future investment. Finally, a provincial power company is taken as an example to demonstrate the feasibility of the proposed investment allocation model.
