Embodiment

[0112] The five smart grids are evaluated, and the indicators after preprocessing are shown in Table 2. The data in the table all represent the degree of realization of the power grid on a certain index. In order to analyze the impact of index changes on the weight and evaluation results, the data of the three smart grid construction stages of the process index are given. It can be seen that the robustness and reliability indicators of smart grid A and B are more prominent, the efficiency and economic indicators of C and D are more prominent, and the interactivity and environmental friendliness indicators of D and E are more prominent. In the actual evaluation of the five power grids, it is necessary to comprehensively consider the development needs of the current smart grid, grasp its development direction as accurately as possible, and then make a targeted and more accurate evaluation of each smart grid.

Abstract

A smart grid evaluation system, comprising an evaluation service platform and at least one terminal center, the evaluation service platform and the terminal center are connected, therein, the terminal center carries out acquisition according to the preset data or the data distributed by the evaluation service platform, the smart grid evaluation indexes are divided into process type indexes and effect type indexes, the process type index used for encouraging pilot project and promotion varies greatly among different regions at the beginning when electric grids at all regions promote smart grid construction simultaneously, along with the comprehensive construction and promotion of the smart grid, construction (process type index) completion degrees become consistent among different regions, whereas the characteristic indicated by the effect type index shows the opposite. In order to reflect different levels of the smart grid construction among different regions, an anti-entropy weight method is adopted for the evaluation service platform to empower the index, the method is characterized in that, the region with a larger variation has a greater weight indicator, and the region with a smaller variation has a smaller weight indicator. Along with the development construction of the smart grid, the weight indicator of the process type index becomes smaller and the weight indicator of the effect type index rises. The rule mentioned above can reflect evaluation demand of the evaluation system along with the smart grid dynamic development.

Description

technical field [0001] The invention relates to a smart grid, in particular to a smart grid evaluation system and method. Background technique [0002] Most of the existing power grid evaluation index systems are proposed for traditional power grids, and there are few literatures for smart grid evaluation. In the "Evaluation Index System of Smart Grid" written by Wang Zhidong, the smart grid evaluation indicators are mentioned comprehensively, and a preliminary establishment In the multi-factor comprehensive index system, there are 3 first-level indicators including smart grid scale foundation, smart grid technical support capability and smart grid development effect, 13 second-level indicators, and 41 third-level indicators. [0003] However, the design of this indicator system is too general and has the following defects: [0004] First of all, with the development of the smart grid, some new features have appeared on the smart grid: such as UHV, clean power, electric veh...
