摘要：
A comprehensive index system, which considers the technique, economy and project maturity, is constructed for investment sequence evaluation of power grid planning projects in the new electricity reform environment. To take the risk preference of decision-makers into account, the utility theory is introduced into the evaluation. Firstly, the utility function of each index is established and the utility value of each index is calculated. Secondly, the weights of above three indexes are obtained based on fuzzy analytical hierarchy process. Finally, the overall utility value of each investment project is obtained based on vector distance merging rule algorithm. Investment sequence evaluation of different planning projects based on IEEE-RTS79 system is carried out. The evaluation results are compared with those obtained from the net present value method, which demonstrates the feasibility and effectiveness of the proposed method. © 2019, Electric Power Automation Equipment Press.
