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

doi:10.3969/j.issn.1000-7229.2016.01.002

Abstract

Abstract:

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.

Key words: power network, investment allocation, Gini coefficient, Lorenz curve, control index
