[0046] To facilitate understanding of the technical solution provided by the present invention, a method for calculating urban carbon emissions provided by the present invention will be described below with reference to the accompanying drawings.

It should be understood that the city refers to the area of ​​a prefecture-level city.

Non-centrally regulated hydroelectricity generation refers to the power generation generated by hydropower stations built within the city. It should be noted that most of the self-built hydropower stations in the city are small hydropower stations. Similarly, the power generation of wind power, photovoltaic power, and clean energy generation other than hydroelectricity, wind power, and photovoltaic power generation in the city are all generated by self-built power stations within the city.

[0049] As a possible implementation method, the city's zero-carbon power generation capacity can be calculated using the following formula:

[0050] Q i,零碳 =Q i,非统调水 +Q i,风电 +Q i,光伏 +Q i,其他清洁能源 (1)

[0051] Among them, Q i,零碳 is the zero-carbon power generation capacity of the city, Q i,非统调水 is the power generation of the non-centralized water in the city, Q i,风电 is the power generation of wind power in the city, Q i,光伏 is the power generation of the photovoltaic power source in the city, Q i,其他清洁能源 It refers to the clean energy other than water, wind and photovoltaic energy in the said city.

It can be understood that non-centrally coordinated coal, non-centrally coordinated gas, and non-centrally coordinated oil refer to the coal, natural gas, and oil required by the prefecture-level city itself, and the local carbon emissions of the city refer to the carbon emissions generated by coal, natural gas, and oil power generation in the city.

[0054] As a possible implementation method, the calculation formula for local carbon emissions in a city is:

[0055] C0 2,i,本地 =k 煤 ×∝ 煤 ×Q i,非统调煤 +k 气 ×∝ 气 ×Q i,非统调气 +k 油 ×∝ 油 ×Q i,非统调油 (2)

[0056] Among them, C0 2,i,本地 is the local carbon emissions of the city, k 煤 is the unit carbon emission of coal, ∝ 煤 is the standard coal consumption for coal-fired power generation, Q i,非统调煤 is the power generation of non-coal dispatching coal, k 气 is the unit carbon emission of gas, ∝ 气 is the standard coal consumption of gas-fired power generation; Q i,非统调气 is the power generation of non-regulated gas, k 油 is the unit carbon emission of fuel, ∝ 油 is the standard coal consumption for fuel-fired power generation, Q i,非统调油 It is the power generation of non-centrally adjusted oil.

It can be understood that unified regulation gas refers to unified regulation natural gas, and unified regulation oil refers to unified regulation petroleum. External coal refers to coal from other provinces that needs to be obtained in the province. The unified regulation carbon emissions of the city's superior province refer to the carbon emissions generated by the unified regulation of electricity in the province.

It can be understood that the shared carbon emission factor of the city's superior province is a relevant parameter used to calculate the carbon emissions that need to be allocated to the city. The provincial power dispatching and control center's coordinated electricity is the power generation that needs to be coordinated and allocated to each city in the power station uniformly built in the province. The provincial power dispatching and control center's coordinated electricity can be calculated based on the coordinated coal power generation, the coordinated gas power generation, the coordinated oil power generation, the provincial hydropower generation, the provincial nuclear power generation, and the power generation of clean energy other than hydropower and nuclear power in the province.

[0064] As a possible implementation method, the calculation formula for the centralized dispatching power of the provincial power dispatching control center is:

[0065] Q 统调 =Q 统调煤 +Q 统调气 +Q 统调油 +Q 水 +Q核 +Q 其他清洁能源 (4)

[0071] In this embodiment of the present invention, the city's allocated carbon emissions are calculated based on the allocated carbon emission factor, the city's total power generation, the city's zero-carbon power generation, the non-centrally coordinated coal generation, the non-centrally coordinated gas generation, and the non-centrally coordinated oil generation. It is understood that the city's allocated carbon emissions refer to the specific carbon emissions that need to be allocated to each prefecture-level city from the city's parent province's centralized carbon emissions.

[0072] As a possible implementation method, the calculation formula for the city's centralized allocation of carbon emissions is:

[0076] In this embodiment of the present invention, the city's carbon emissions are calculated based on the city's local carbon emissions and the city's centralized carbon emissions. It is understood that the city's local carbon emissions are calculated in step S102, while the city's centralized carbon emissions are calculated in step S105.

[0077] As a possible implementation method, the calculation formula for the carbon emissions of the city is:

It can be seen that the above method takes into account the contribution of the city's zero-carbon power generation to carbon reduction, includes the contribution of wind power generation and photovoltaic power generation planned and constructed in the province into the local area, and includes the contribution of clean energy emission reduction that is not planned and constructed in the province into the local area, reasonably shares the city's superior provincial coordinated carbon emissions and the total carbon emissions generated by the provincial coordinated energy power generation, and improves the calculation accuracy of the city's carbon emissions.
