The Quantitative Evaluation Research of Grid Planning Economy Based on Improved DEA Model

Abstract:

To solve the problem for the complexity of the quantitative evaluation of grid planning economy, in accordance with the principle of cost-benefit analysis, and combined with the characteristics of UHV power grid, we construct an input-output index system which contains the planning costs, economic benefits, the benefits of interconnection, environmental benefits, social benefits and other benefits in this paper. And for the problem of comparison between unexpected output indicators and effective unit that exists in the index system, we improve the traditional data envelopment analysis (DEA), and build a quantitative evaluation model of grid planning economy based on the improved DEA model. Finally, use the data of the planning program of a UHV grid, to test and verify the established evaluation model. The results show that the model is reasonable and effective.
