Problems solved by technology

This method has led to the inability to effectively transmit the cost of carbon emissions to the power user side, resulting in distortion of carbon emissions prices
At the same time, electricity users cannot feel the carbon emissions caused by their electricity consumption behavior, so they have no motivation to participate in energy conservation and emission reduction

Abstract

The invention discloses a power consumer carbon emission cost sharing method based on carbon emission power price, and solves the problem that the carbon emission cost of the power industry is on the power generation side and cannot be conducted to the power consumer side so that the user cannot be promoted to participate in energy conservation and emission reduction. The function relationship between the load of the power consumer and the system carbon emission is determined by using a power flow tracing technology in the method. The marginal carbon emission of the system caused by the load of the user and the corresponding marginal carbon emission cost are determined by using the optimal power flow model, and the cost is reflected in the power price of the user. According to the method, the user is enabled to know the influence of his power consumption on the carbon emission of the power system through the means of power price so that the user is promoted to transfer his power load to the moment of high output of wind power, photovoltaic and other clean power supplies so as to objectively realize the effect of reducing the carbon emission of the power system. Meanwhile, a scientific and reasonable cost mechanism is established by the method, and the problem of sharing of the cost related to the carbon emission is solved.

Description

technical field [0001] The invention relates to the field of power system scheduling and management, in particular to a carbon emission cost allocation method for electric power users based on carbon emission electricity prices. Background technique [0002] In my country's power system, thermal power occupies a dominant position, causing the power system to become one of the largest sources of carbon emissions. The traditional carbon emission measurement method uses the power source as the carbon emission source, and the carbon emission intensity and power generation of the generator set as its carbon emission, and carbon emission fees are levied on it. This method has led to the inability to effectively transmit the cost of carbon emissions to the power user side, resulting in distortion of carbon emissions prices. At the same time, electricity users cannot feel the carbon emissions caused by their electricity consumption behavior, so they have no motivation to participat...
