【 摘 要 】

With the rapid development of economy, more and more requirements are being made on the investment and operating efficiency of power grid. Therefore, it's necessary to establish an evaluation method of grid operation benefit based on operation data. This paper establishes a fuzzy comprehensive evaluation method to evaluate the operation benefit of power grid based on the improved variable weight theory. Firstly, a perfect index system is established, and the dimensionless calculation method in the efficacy coefficient method is introduced. Then the improved variable weight theory algorithm is studied. It makes more effective use of earned scores by introducing a non-const equilibrium coefficient, and the calculation process of the fuzzy comprehensive evaluation method is given. Finally, an example is illustrated to verify the feasibility and effectiveness of the proposed algorithm.
