A Study on Grading Early Warning Model of Distribution Network Investment Deviation

The grading early warning model of distribution network investment deviation can invest in distribution network construction project and provide scientific and economic management model. In this paper, factors that caused distribution network construction investment deviation has been identified effectively, the distribution network construction investment deviation early warning index system was built through the selected technical-economic indicators; furthermore, a comprehensive analysis of investment deviation by using analytic hierarchy process was carried out, and then, started from fuzzy evaluation and grey evaluation method, a investment deviation early grading model that combined with fuzzy and grey was established. In this paper, a concrete example was given to demonstrate the smart grid investment deviation grading early warning model is practical.
