Indicates the amount of gas produced after burning 1kg of standard coal. Emissions, where the best value of this parameter is 2.5; Represents the power regulation of the wind power storage virtual power plant Get the amount of coal needed to consume the same amount of electricity; Coal consumption The expression is:

[0048] In the formula, Indicates the power regulation amount. The unit of power regulation amount is kW·h. Indicates the calorific value of coal. The unit of calorific value of coal is MJ / kg. Indicates power generation efficiency; In this embodiment, the indirect carbon value is calculated based on the life cycle method to calculate the carbon emissions generated by the wind and solar power generation equipment in the wind, solar and energy storage virtual power plant. , and then according to the carbon trading price and energy conservation and emission reduction subsidies The indirect carbon value generated by the wind, solar and energy storage virtual power plant can be obtained. It can be understood that the life cycle approach is used to evaluate the changes in the entire process of product or service from production, installation, use to scrapping. Based on the life cycle approach, the present invention calculates the carbon emissions generated by the wind and solar units in the wind, solar and energy storage virtual power plant during the material production and manufacturing stage, transportation and installation stage, and operation and maintenance stage. The indirect carbon value accounting module is as follows:

Calculated based on ((1-actual output power / rated output power)*100%).

[0050] Understandably, when hour, It represents the consumption of the wind, solar and energy storage virtual power plant in the first stage of its life cycle, that is, the consumption of the wind, solar and energy storage virtual power plant in the material production and manufacturing stage of its life cycle. hour, It represents the consumption of the wind, solar and energy storage virtual power plant in the second stage of its life cycle, that is, the consumption of the wind, solar and energy storage virtual power plant in the transportation and installation stage of its life cycle. hour, It represents the consumption of the wind, solar and storage virtual power plant in the third stage of its entire life cycle, that is, the consumption of the wind, solar and storage virtual power plant in the operation and maintenance stage of its entire life cycle.

[0051] The carbon value calculation results are obtained based on the direct carbon value calculation model and the indirect carbon value calculation model, as follows:

[0052] In the formula, Indicates the carbon value accounting results, represents the carbon trading price, represents energy conservation and emission reduction subsidies, Represents the initial carbon emissions of the virtual power plant.

[0053] This paper constructs a comprehensive and scientific carbon value accounting model by comprehensively considering the direct and indirect carbon emissions of virtual power plants, as well as their potential value in energy conservation, emission reduction and carbon trading. This model can not only accurately reflect the actual contribution of virtual power plants in reducing carbon emissions, but also provide a strong basis for them to gain more support in the carbon trading market and energy conservation and emission reduction policies.

[0054] The present invention can comprehensively and accurately evaluate the carbon emissions reduced by virtual power plants during operation, and derive the carbon value of virtual power plants accordingly. This accounting method not only considers the direct impact of the power energy regulation of virtual power plants on carbon emissions, but also incorporates the carbon emissions generated during the construction of unit equipment, thereby more realistically reflecting the carbon footprint of virtual power plants.

[0055] According to the above steps, the carbon emissions reduced by the wind, solar and storage virtual power plant are calculated based on the power regulation data of the wind, solar and storage virtual power plant. This embodiment takes the power regulation of the wind, solar and storage virtual power plant in 2023 as 1.258 million kW·h as an example. In this example, the calorific value of coal is 20MJ / kg, and the power generation efficiency is 35%. The amount of coal required to consume the same amount of electricity is 646971.429kg, so according to the formula Get the carbon emissions reduced by the wind, solar and energy storage virtual power plant. Here the parameters are The value is 2.5, and the calculated result is 1617428.571kg.

[0056] Then, the carbon emissions generated by wind-solar units in the wind-solar-storage virtual power plant during the three stages of production and manufacturing, transportation and installation, and operation and maintenance are calculated based on the life cycle method. For each stage, the carbon emission sources of wind-solar units are mainly the consumption of electricity and heat energy. Since specific data are difficult to obtain, the formula is used here: Represents the carbon emissions generated by wind and solar power units at each stage.

[0057] Finally, the carbon value generated by the wind, solar and energy storage virtual power plant is calculated according to the carbon value accounting formula. 0.95 yuan / kg, energy saving and emission reduction subsidy The initial carbon emission quota per unit of electricity generated is 0.798 kg / (Kw·h), which is 20% of the actual investment in software and hardware. The carbon value generated by the wind, solar and storage virtual power plant is:
