Investment allocation model based on Gini coefficient and its application to electric power subsidiaries

In this paper, Gini coefficient is introduced into the allocation of investments in electric power subsidiaries. First, three indicators including the return on total assets, future forecasted electricity consumption and the investment to electricity sales ratio are used to determine the initial allocation scheme of future grid investment in subsidiaries. The initial scheme ensures benefits (efficiency) priority. Then, control indicators such as the capacity-load ratio, power grid reliability are used in designing investment allocation model based on the Gini coefficient. The proposed model optimizes the initial allocation scheme from the perspective of improving the fairness. Finally, a provincial electric power company in China is taken as an example to verify the feasibility of the proposed model.
