Description

technical field [0001] The invention relates to a simulation analysis method, in particular to a power system carbon flow simulation analysis method suitable for large-scale power grids. Background technique [0002] The measurement of carbon emissions is the basis for all carbon emission reduction work. At present, there are two main carbon emission measurement methods commonly used in the power industry: direct analysis method and full life cycle method. The direct analysis method is to first count the total consumption of various fossil fuels, and then calculate the total carbon emissions according to the carbon emission factors of various fossil fuels; the whole life cycle analysis is to expand the direct method in the time dimension, and the whole life cycle The analysis starts with the construction of power plants, the assembly of generator equipment, the mining and transportation of fuels, and combines the operation, management, maintenance and decommissioning of pow...

Problems solved by technology

[0005] At present, there are preliminary carbon flow calculation methods, but the current carbon flow calculation methods have many inadaptable problems in large-scale power grid applications, including: 1) The DC system is not considered at all; 2) It is difficult to solve the large-scale grid without using sparse matrix technology. Calculation of large-scale data carbon flow; 3) It has not been verified by actual grid data, and cannot adapt to the complex and changeable situation of the actual grid; 4) The calculation indicators are too scattered and not suitable for grid simulation

In addition, the current carbon flow calculation method is limited to carbon flow calculation, and does not combine the grid carbon flow simulation analysis with the actual simulation analysis of the power grid, which is not conducive to actual users.
