Description

Technical Field

[0001] The present invention relates to the field of carbon emission assessment, and in particular to a method, device, equipment and medium for dynamic carbon balance assessment during the life cycle of a hydropower project. Background Art

[0002] Since its inception in the 1960s, the Life Cycle Assessment (LCA) method has gradually expanded from analyzing the environmental impact of single industrial products to carbon accounting for complex engineering systems. As hydropower projects have become a key component of clean energy, their lifecycle carbon emissions accounting has gradually become a focus of industry attention. Currently, the traditional LCA method is widely used in the industry.

[0003] Traditional life cycle assessment (LCA) methods have significant limitations: First, accounting boundaries are often limited to single projects, failing to incorporate system-level carbon benefits such as multi-energy complementarity and coordinated power dispatch within a watershed. This has led to the long-term neglect of the emission reduction benefits of cascade hydropower stations in terms of peak-shaving and valley-filling for wind and solar power consumption. Second, dynamic evaluation capabilities need to keep pace with the times. Key variables such as the proportion of clean energy borrowed during the construction period and the replacement rate of new energy construction equipment are simplified to fixed parameters, making it impossible to quantify the optimization potential of low-carbon technology iterations. Third, data granularity is relatively coarse, especially in areas such as reservoir greenhouse gas emissions and ecological carbon sinks, which rely on IPCC global averages and deviate significantly from the actual emissions of the projects. Therefore, how to develop a more accurate life cycle assessment method for hydropower projects and provide more precise guidance for carbon emission reduction is an urgent issue.

[0058] A method for dynamic carbon balance evaluation during the life cycle of a hydropower project comprises: obtaining construction and operation data of the hydropower project; determining the total carbon emissions during the construction period based on the construction and operation data; determining the carbon emissions during the operation period based on the construction and operation data; determining the annual net carbon emission reduction during the operation period of the project based on the construction and operation data; and conducting a dynamic carbon balance evaluation and analysis of the hydropower project based on the total carbon emissions during the construction period, the carbon emissions during the operation period, and the annual net carbon emission reduction during the operation period of the project.

[0059] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0060] First, the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.
