A post-evaluation Research of Economical Effects for Power Grid Construction Project Based on ANP-Hesitate Linguistics

linguistic; cloud model; Abstract: In electric power system reform environment, grid companies have to estimate the economic performance of power grid construction project completed with a more market-oriented perspective. Therefore, economic efficiency post-appraisal model of the power grid is proposed in this paper. In view of the problem of evaluating of economic benefits only from financial angle in existing research, lack of comprehensiveness and depth, including construction costs, financial, social and economic benefits and environmental impact costs four aspects were build as the index system with network hierarchy. On this basis, the ANP method to solve the index weight was put forward, and hesitate linguistic evaluation method for policymakers, finally cloud model assembled each index evaluation result.In the end, three power grid construction projects in liaoning province had built were used for verifying the feasibility and rationality of the model.
