Embodiment 1

[0163] As shown in Table 2, the comprehensive evaluation values ​​of the four first-level indicators in the embodiments of grid A and grid B are calculated by using the above steps

[0164] Table 2 The comprehensive evaluation value of the first-level indicators of power grid A and power grid B

[0165]

[0166] Using the G-1 weighting method, the weights of the four primary indicators of grid A and grid B are obtained, as shown in Table 3.

[0167] Table 3 The weight of the first-level indicators of grid A and grid B

[0168]

[0169] Such as Figure 4 Shown is a schematic diagram of the comprehensive evaluation results of the grid A and grid B embodiments represented by radar charts. It can be seen from the figure that grid B occupies a larger area in the radar chart, indicating that its comprehensive energy saving level is higher, but grid A is better than grid B in terms of grid structure and grid equipment.

Abstract

The invention provides an evaluation method of an energy-saving type power grid. The evaluation method comprises the steps of 1. establishing an evaluation index system of the energy-saving type power grid, wherein the evaluation index system is provided with four kinds of indexes such as power grid structure, power grid operation, power grid management and power grid equipment; 2. dividing the indexes in the evaluation index system into a maximum type, a minimum type and a moderate type; 3. converting the minimum type index and the moderate type index into the maximum type index; 4. carrying out dimensionless treatment on the indexes; 5. removing the correlation among the indexes; 6. empowering all levels of indexes; and 7. determining a comprehensive evaluation result of the four kinds of indexes according to dimensionless values and weights of the indexes. According to the evaluation method provided by the invention, the energy-saving level can be judged according to the evaluation indexes, thus the advantages and the disadvantages of lower carbon and energy saving benefits of the power grid are obtained; the evaluation indexes are divided into four kinds, namely power grid structure, power grid operation, power grid management and power grid equipment, and the energy saving benefit of the power grid is reflected by each kind on a certain macro level.

Description

technical field [0001] The invention relates to the technical field of power system performance evaluation, in particular to an evaluation method for an energy-saving power grid. Background technique [0002] Energy saving and emission reduction is an important way for the development of all countries. In recent years, energy and environmental issues have increasingly become the focus of global attention. In order to cope with global climate change and achieve sustainable energy development, developing an energy-saving economy has become the common choice of all countries in the world. All countries are committed to large-scale development of renewable energy, improving energy efficiency, and reducing greenhouse gas emissions, so as to promote the transformation of the entire social economy to a model of high energy efficiency, low energy consumption, and low carbon emissions. [0003] There is a lot of room for energy saving in the power industry. The power industry is a...
