Embodiment Construction

[0015] An embodiment of a method for judging the energy saving level of China's power grid proposed by the present invention is characterized in that it includes two parts:

[0016] The first part: Establish the judgment index set of "energy-saving power grid": analyze the various energy consumption in each link in the operation process of the power grid from the transmission and distribution links, and classify them into four categories according to the nature of different energy consumption. energy consumption, grid operation energy consumption, grid equipment energy consumption and grid management energy consumption; for each type of energy consumption, the corresponding indicators and the calculation formulas of each indicator are given respectively; based on this, the energy consumption indicators for evaluating the energy saving characteristics of the grid are formed system;

[0017] The second part: Use the calculation formula of the index to judge the energy-saving lev...

Abstract

The invention relates to a judgment method of power grid power-saving level. The judgment method comprises establishment of judgment index set of 'power-saving power grid' : all kinds of energy consumption of each link in the process of power grid operation are analyzed from power transmission and distribution, and all kinds of energy consumption are classified into for categories according to different properties, namely energy consumption of power grid structure, energy consumption of power grid operation, energy consumption of power grid equipment, and energy consumption of power grid management. Corresponding judgment index and formulas of the index are given to each kind of energy consumption, and energy consumption index system of assessment of power grid energy-saving features is formed based on all above. Power grid energy-saving level is judged by the formulas of the index to obtain energy consumption level of each link. Energy consumption structure of each link and energy-saving potential of each link is disclosed. Low efficiency link and reasons of low efficiency are found through identification and comparison. Construction of an evaluation index system of energy-saving power grid provides direct basis for the analysis and evaluation of energy-saving level of power grid.

Description

technical field [0001] The invention belongs to the technical field of power system performance judgment, and in particular relates to an evaluation index system and an evaluation method of the energy-saving level of a 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 sav...
