[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0039] This embodiment provides a method and system for regional CCUS emission reduction path planning. Figure 1-2 Describe them together.

[0040] Example

[0041] At present, with the popularization of the concept of carbon neutrality and the stable implementation of relevant measures, it is particularly important to effectively and quickly integrate the emission reduction costs of various CCUS technologies and plan regional CCUS emission reduction paths, but there is a lack of relevant methods. Therefore, it is very necessary to establish a regional CCUS emission reduction path planning method for CCUS technology collaboration and a system for reasonably implementing this method.

[0042] This embodiment provides a regional CCUS emission reduction path planning method, the execution of which relies on a computer controller and includes:

[0043] First, the total emission reduction in the planned area in the past year and the types of CCUS emission reduction technologies used in the past year are obtained, where CCUS emission reduction technologies include: oil recovery and storage technology, geological storage technology, chemical conversion and utilization technology, and mineralization utilization technology. This embodiment does not limit the types of emission reduction technologies used, and any type of technology belonging to CCUS emission reduction technology can be combined with the method of this embodiment. It should be noted that the purpose of not limiting is to improve the adaptability of the method and add more possible usage scenarios.

[0044] Next, the maximum emission reduction of the CCUS emission reduction technology that has been used in the planning area in the past year is obtained, and an emission reduction database is established for the maximum emission reduction in the planning area in the past year. The emission reduction peak value of the emission reduction database is divided into M 1 、M 2 and M 3 Specifically, the peak emission reduction amount is divided according to the preset value difference level, and the preset value difference level includes the first level difference M 1 , Secondary difference M 2 And the third level difference M 3 , wherein the preset value difference level is the difference range level between the standard value and the actual value of the emission reduction. It should be further explained that the first level difference M in this embodiment 1, Secondary difference M 2 And the third level difference M 3 It is the difference between the standard emission reduction peak value and the actual emission reduction peak value. In other words, the preset value difference level referred to in this embodiment is also the difference between the emission reduction peak values.

[0045] Then, the unit emission reduction cost is estimated for each partition, and the estimated value set A is obtained. 1 Perform unit emission reduction cost estimation and obtain the estimated value A 1 , for M 2 Perform unit emission reduction cost estimation and obtain the estimated value A 2 , for M 3 Perform unit emission reduction cost estimation and obtain the estimated value A 3 , where the estimated value A 1 , A 2 and A 3 They are collectively referred to as the estimated value set A. It should be noted that the reason why the unit emission reduction cost estimation is performed for the division is that under the unit measurement, the emission reduction cost data is more intuitive and the accuracy of the data is higher than the overall data; at the same time, in other scenarios, other measurement units can be selected as needed.

[0046] In some embodiments, M 1 Perform unit emission reduction cost estimation and obtain the estimated value A 1 , specifically:

[0047] Using the following formula, we get M 1 Unit reduction rate:

[0048]

[0049] Among them, E 1 Represents M 1 Unit emission reduction rate; e max is the maximum emission reduction per unit; e min is the minimum emission reduction per unit; e standard is the unit emission reduction standard deviation; 1 For comparison, when E 1 When it is greater than 100%, it represents the first-level difference M 1 The results of medium unit emission reduction are excellent; when E 1 When it is equal to 100%, it represents the first-level difference M 1 The results of the unit emission reduction are qualified; when E 1 When it is less than 100%, it represents the first-level difference M 1 The results of the unit emission reduction were unsatisfactory.

[0050] It should be noted that when E 1 Greater than 100% and when E 1When it is equal to 100%, the corresponding e max 、e min The data will be adopted, otherwise when E 1 When it is less than 100%, it means M 1 The unit emission reduction rate is lower than the standard emission reduction rate, which does not meet the emission reduction requirements of carbon neutrality. The corresponding e max 、e min The maximum unit emission reduction and the minimum unit emission reduction corresponding to the qualified and excellent emission reduction rates are recorded as A 1 .

[0051] In some embodiments, M 2 Perform unit emission reduction cost estimation and obtain the estimated value A 2 , specifically:

[0052] Using the following formula, we get M 2 Unit reduction rate:

[0053]

[0054] Among them, E 2 Represents M 2 Unit emission reduction rate; e max is the maximum emission reduction per unit; e min is the minimum emission reduction per unit; e standard is the unit emission reduction standard deviation; 2 For comparison, when E 2 When it is greater than 100%, it represents the secondary difference M 2 The results of medium unit emission reduction are excellent; when E 2 When it is equal to 100%, it represents the secondary difference M 2 The results of the unit emission reduction are qualified; when E 2 When it is less than 100%, it represents the secondary difference M 2 The results of the unit emission reduction were unsatisfactory.

[0055] It should be noted that when E 1 Greater than 100% and when E 1 When it is equal to 100%, the corresponding e max 、e min The data will be adopted, otherwise when E 1 When it is less than 100%, it means M 1 The unit emission reduction rate is lower than the standard emission reduction rate, which does not meet the emission reduction requirements of carbon neutrality. The corresponding e max 、e min The maximum unit emission reduction and the minimum unit emission reduction corresponding to the qualified and excellent emission reduction rates are recorded as A 2 .

[0056] In some embodiments, M 3 Perform unit emission reduction cost estimation and obtain the estimated value A 3 , specifically:

[0057] Using the following formula, we get M 3 Unit reduction rate:

[0058]

[0059] Among them, E 3 Represents M 3 Unit emission reduction rate; e max is the maximum emission reduction per unit; e min is the minimum emission reduction per unit; e standard is the unit emission reduction standard deviation; 3 For comparison, when E 3 When it is greater than 100%, it represents the third level difference M 3 The results of medium unit emission reduction are excellent; when E 3 When it is equal to 100%, it represents the third level difference M 3 The results of the unit emission reduction are qualified; when E 3 When it is less than 100%, it represents the third level difference M 3 The results of the unit emission reduction were unsatisfactory.

[0060] It should be noted that when E 1 Greater than 100% and when E 1 When it is equal to 100%, the corresponding e max 、e min The data will be adopted, otherwise when E 1 When it is less than 100%, it means M 1 The unit emission reduction rate is lower than the standard emission reduction rate, which does not meet the emission reduction requirements of carbon neutrality. The corresponding e max 、e min The maximum unit emission reduction and the minimum unit emission reduction corresponding to the qualified and excellent emission reduction rates are recorded as A 3 .

[0061] Finally, for the estimated value set A, the emission reduction path planning is implemented. In detail, the maximum unit emission reduction e in A is obtained by comparison. max , for the maximum unit emission reduction e max The CCUS emission reduction technology used is traced back to determine the corresponding emission reduction technology. It should be noted that the reverse tracing method is to obtain the maximum emission reduction amount e in A. max The corresponding emission reduction technology is derived. It should be noted that the maximum emission reduction e maxAs the starting point for reverse calculation, it is to ensure that the relevant emission requirements of carbon neutrality are met to the greatest extent. min As a reverse starting point, it is impossible to meet the relevant emission requirements for carbon neutrality to the greatest extent.

[0062] In order to better understand the method of the present application, the present embodiment also provides a regional CCUS emission reduction path planning system, specifically comprising: a control module, the control module executes the regional CCUS emission reduction path planning method.
