[0001] The present invention relates to a field, and in particular to a carbon market trading method and device considering buildings, and a computer-readable storage medium. Background Art

[0002] At present, some regions have proposed a mutual recognition method for green electricity and certified emission reduction certificates based on the goal of "certificate and electricity integration" to transfer green certificates simultaneously with green electricity. However, this method ignores the problem of repeated recognition of environmental efficiency, resulting in double incentives for green electricity. At the same time, existing technology research on electricity-carbon synergy is mainly concentrated in the field of power generation. There is currently no mutual recognition method for green electricity consumption and carbon markets with buildings as the main body.

[0003] The above-mentioned existing mutual recognition mechanisms are usually concentrated in the power generation field, and lack a mutual recognition method based on buildings. This leads to poor trading efficiency in the carbon market for building entities based on mutual recognition technology. No effective solution has been proposed so far. Summary of the invention

[0038] According to an embodiment of the present invention, a method embodiment of a carbon market trading method considering buildings is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0039] Figure 2 is a flow chart of a carbon market trading method considering buildings according to an embodiment of the present invention. Figure 2 As shown, the method comprises the following steps:

[0040] Step S202, determining the electricity-carbon mutual recognition mechanism of the target building when the green electricity consumption is mutually recognized by the carbon market, wherein the electricity-carbon mutual recognition mechanism is used to represent the mechanism by which the target building obtains carbon emission reductions recognized by the carbon market by consuming green electricity.

[0041] In this embodiment, the electricity-carbon mutual recognition mechanism of the target building when the green electricity consumption and the carbon market are mutually recognized can be determined first, so as to determine how each target building can specifically perform mutual recognition between green electricity consumption and the carbon market based on the mutual recognition mechanism.

[0042] According to the above embodiment of the present invention, before the above step S202, that is, before determining the electricity-carbon mutual recognition mechanism of the target building when the green electricity consumption and the carbon market are mutually recognized, the carbon market trading method considering the building also includes: obtaining the emission reduction attributes of each building in the building; dividing the buildings into mandatory buildings, emission reduction buildings and zero-carbon buildings according to the emission reduction attributes, wherein the mandatory building refers to the building located in the control ranking list, the emission reduction building refers to the building whose emission reduction is within the predetermined emission reduction range, the zero-carbon building refers to the building with zero carbon emission as the emission reduction target, and the control ranking list is the list of buildings that need to control the emission reduction; determine the mandatory buildings, emission reduction buildings and zero-carbon buildings as different types of target buildings.

[0043] Combine the following Figure 3 The above embodiments of the present invention are described in detail. Figure 3 is a flow chart of an optional carbon market trading method considering buildings according to an embodiment of the present invention.

[0044] like Figure 3As shown, first of all, buildings can be divided into mandatory buildings, emission reduction buildings and zero-carbon buildings according to their emission reduction attributes. The definitions and classification standards of various types of buildings are as follows: 1) Mandatory buildings: Mandatory buildings are defined as buildings on the control ranking list to achieve total carbon emission control; such buildings have a large energy consumption base and are usually allocated some free quotas. They need to pay carbon quotas equal to their total carbon emissions for the year at the end of the year to fulfill their obligations. According to the current rules for considering the participation of buildings in the carbon market, such buildings are on the carbon market control ranking list and are divided according to area or total energy consumption; such buildings are usually buildings that need to control emission reductions; 2) Emission reduction buildings: Emission reduction buildings are defined as buildings that can be registered as emission reduction projects and recognized as emission reduction (CCER) certificates. Such buildings are generally equipped with basic distributed power generation equipment and have emission reduction characteristics, that is, emission reduction buildings can reduce as much as possible during design, construction and use. Buildings that generate carbon emissions and other greenhouse gas emissions to the environment. Such buildings usually use energy-saving and environmentally friendly materials and technologies, and reduce energy consumption and environmental impact by optimizing building structure, lighting design, ventilation system and other means. They can also reduce carbon emissions, improve energy efficiency and reduce resource consumption, thereby reducing the negative impact of climate change; 3) Zero-carbon buildings: Zero-carbon buildings have clear emission reduction targets, requiring their own annual total carbon emissions to be zero, that is, direct and indirect carbon emissions are equal to emission reductions, and indirect carbon emissions from purchased electricity are the main source of carbon emissions for buildings. Considering the carbon emission balance of this part of the building's electricity, in addition, zero-carbon buildings generally have their own distributed renewable energy power generation equipment. Such buildings can achieve a balance between the building's energy demand and energy consumption as much as possible throughout their life cycle by adopting energy-efficient design, building materials and construction technology, as well as using renewable energy and other measures, thereby making the building's net carbon emissions zero.

[0045] It should be noted that the CCER here can be understood as a certified emission reduction certificate obtained by the target building by consuming green electricity and conducting electricity-carbon mutual recognition. Each certified emission reduction certificate CCER can be used to offset a certain amount of carbon emissions.

[0046] According to the above embodiment of the present invention, in the above step S202, the electricity-carbon mutual recognition mechanism of the target building when the green electricity consumption and the carbon market are mutually recognized is determined, including: when the target building is a mandatory building, the electricity-carbon mutual recognition mechanism is determined as: mutual recognition and conversion between the green electricity consumption of the mandatory building and the quota surplus, wherein the quota surplus is the difference between the total carbon emissions held by the mandatory building and the actual carbon emissions; when the target building is an emission reduction building or a zero-carbon building, the electricity-carbon mutual recognition mechanism is determined as: mutual recognition and conversion between the green electricity consumption of the mandatory building and the certified emission reduction certificate.

[0047] As above Figure 3 As shown in the figure, for different types of buildings, according to their different emission reduction properties, the green power consumption and carbon market mutual recognition mechanism (electricity-carbon mutual recognition mechanism) applicable to different types of buildings can be obtained respectively. The mutual recognition mechanism of each type of building usually includes three parts: performance constraints, mutual recognition objects and mutual recognition process. The mutual recognition mechanism of each type of building is explained in detail below: (1) Mandatory buildings: ① Mandatory buildings hold a certain number of free quotas. At the end of the year, they need to hand in the quotas and CCERs corresponding to the number of carbon emissions when calculating the performance. That is, the performance constraints at the end of the year are: carbon emissions Total amount = quota held + CCER number (subject to compliance ratio restrictions); ② The corresponding free quota surplus corresponds to the green electricity consumed by mandatory buildings, and the corresponding mutual recognition object is: the conversion of green electricity consumption and quota surplus; ③ The mutual recognition process is: a. The mandatory building entity consumes green electricity and the carbon emissions of purchased electricity are recognized as zero; b. The carbon emissions of the purchased point are recognized to be reduced, and the mandatory building has a free quota surplus; (2) Emission reduction buildings: ① The transaction and certification of emission reduction buildings are mainly voluntary, and there are no mandatory emission reduction targets and constraints. The amount of green electricity consumed is the emission reduction amount. Emission reduction buildings satisfy the following formula: Carbon emission reduction = emission reduction corresponding to green electricity consumption; ② The carbon emission reduction corresponding to green electricity consumption by emission reduction buildings can be certified with the corresponding emission reduction and CCER certificate can be obtained. The corresponding mutual recognition object is: the conversion of green electricity consumption and CCER; ③ The mutual recognition process is: a. The carbon emission of purchased electricity is recognized as zero when the emission reduction building consumes green electricity; b. The carbon emission reduction of the emission reduction building increases; (3) Zero-carbon buildings: ① Zero-carbon buildings require that their total carbon emissions are zero within a certain period of time. Since zero-carbon buildings can generate green electricity and consume green electricity and thermal power supplied by the power grid, the green electricity they consume can be recognized as zero carbon emissions, the thermal power they consume can be recognized as positive carbon emissions, and the green electricity they generate can be recognized as negative carbon emissions. The annual carbon emissions of zero-carbon buildings are The constraint of positive carbon emissions = negative carbon emissions must be met, that is: the carbon emissions corresponding to the fossil energy electricity consumed = the equivalent carbon savings of the green electricity supplied to the outside + the amount of CCER purchased; ② The environmental recognition right of green electricity is transferred from the source to the receiving end, and the zero-carbon building will obtain green electricity benefits by supplying green electricity to the outside, including electricity benefits and environmental premium. The green electricity supplied to the outside can no longer be recognized as CCER, and its recognition right is transferred to the user side that consumes the corresponding green electricity, while the green electricity consumed by the zero-carbon building can be recognized as the corresponding CCER. The corresponding mutual recognition object is: the conversion of green electricity consumption and CCER; ③ The mutual recognition process is: a. The carbon emissions of the green purchased electricity consumed by the main body of the zero-carbon building are zero; b. The carbon emission reduction recognition of the main body of the zero-carbon building increases, and the pressure on the zero-carbon recognition indicator of the zero-carbon building is reduced.

[0048] Step S204, determining the mutual recognition factor of the target building when the green power consumption and the carbon market are mutually recognized according to the electricity-carbon mutual recognition mechanism, wherein the mutual recognition factor is the exchange coefficient between the green power consumption and the carbon emission reduction when mutual recognition is performed.

[0049] In this embodiment, the mutual recognition mechanism of each type of building can be used to determine the optimal mutual recognition factor of the corresponding target building when the green power consumption and the carbon market are mutually recognized. The mutual recognition factor serves as the exchange coefficient between the green power consumption and the carbon emission reduction of the target building when the mutual recognition is carried out. It can be calculated how many CCERs the green power consumed by the target building can be converted into, thereby offsetting the carbon emissions of the target building itself.

[0050] According to the above embodiment of the present invention, in the above step S204, the mutual recognition factor of the target building when the green power consumption and the carbon market are mutually recognized is determined according to the electricity-carbon mutual recognition mechanism, including: determining the emission reduction equivalent mutual recognition strategy and environmental benefit mutual recognition strategy of the target building when the green power consumption and the carbon market are mutually recognized based on the electricity-carbon mutual recognition mechanism, wherein the emission reduction equivalent mutual recognition strategy is a strategy for converting the green power consumption of the target building into a certified emission reduction certificate, and the environmental benefit mutual recognition strategy is a strategy for converting the environmental attributes of green power into a certified emission reduction certificate; when the target building is mutually recognized according to the emission reduction equivalent mutual recognition strategy, the first mutual recognition factor of the target building is determined by using the first formula, wherein the first formula is: η 1 represents the first mutual recognition factor, α base,i represents the baseline carbon dioxide emission factor for the source region, α base,j It represents the baseline emission factor of carbon dioxide in the receiving area. The source area refers to the area where green electricity is produced, and the receiving area refers to the area where green electricity is consumed. When the target building follows the environmental benefit mutual recognition strategy, the second mutual recognition factor of the target building is determined by the second formula, where the second formula is: η 2,t represents the second mutual recognition factor at time t, C c,t represents the market price of carbon emission quota or certified emission reduction certificate at time t, C g,t It represents the price of unsubsidized green certificate at time t, and the carbon emission quota refers to the amount of carbon emissions held by the target building. The first mutual recognition factor and the second mutual recognition factor are fitted to obtain the mutual recognition factor.

[0051] As above Figure 3As shown, based on the mutual recognition mechanism of green power consumption and carbon market of different types of buildings, two mutual recognition methods can be proposed: mutual recognition method based on emission reduction equivalent and mutual recognition method based on environmental benefits. Among them, the mutual recognition method of emission reduction equivalent is converted according to regional carbon emission factors, and the mutual recognition method based on environmental benefits is converted according to green power environmental premium and CCER market price / carbon quota market price. In this way, the mutual recognition factors obtained by the two mutual recognition methods are fitted to obtain a more reasonable mutual recognition factor. It should be noted that in the specific implementation process, it is not limited to these two mutual recognition methods, and can be selected in combination with actual conditions. No specific restrictions are made here.

[0052] The mutual recognition process of these two mutual recognition methods is explained below: 1) Mutual recognition based on emission reduction equivalent: Combined with the regional power grid carbon dioxide baseline emission factor, the mutual recognition factor for inter-provincial green electricity is the weighted average of the carbon dioxide baseline emission factors of the power grids in the source area and the receiving area. The specific formula is as follows: η 1 represents the first mutual recognition factor, α base,i represents the baseline carbon dioxide emission factor for the source region, α base,j Represents the baseline carbon dioxide emission factor of the receiving area. The source area refers to the area where green electricity is produced, and the receiving area refers to the area where green electricity is consumed; 2) Mutual recognition based on environmental benefits: Combine the carbon market and the green electricity market to conduct equivalent mutual recognition of CCER and green electricity. The environmental attributes of green electricity can be mutually recognized based on the current status of China's green certificate market. At present, the CCER price of per kilowatt-hour emission reduction is similar to the price of unsubsidized green certificates, so it is converted based on the market CCER price and the price of unsubsidized green certificates. This mutual recognition is closely related to the prices of the two markets and is a dynamic mutual recognition factor. The specific formula is as follows: η 2,t represents the second mutual recognition factor at time t, C c,t represents the market price of carbon emission quota or certified emission reduction certificate at time t, C g,t It represents the price of unsubsidized green certificate at time t, and carbon emission quota refers to the amount of carbon emissions held by the target building. Then, the mutual recognition factors under the two mutual recognition methods of Jiangsu and Zhejiang are fitted to obtain the mutual recognition factors of the green electricity consumed by the target building and CCER.

[0053] Step S206, determining the number of certified emission reduction certificates obtained by the target building based on the mutual recognition factor and the amount of green electricity consumed by the target building, wherein the certified emission reduction certificate is a certificate used to offset a predetermined amount of carbon emission reduction.

[0054] In this embodiment, the number of certified emission reduction certificates CCER obtained by the target building, that is, the number of CCERs, can be calculated based on the mutual recognition factor and the green electricity consumption of the target building.

[0055] According to the above embodiment of the present invention, in the above step S206, the number of certificates of the certified emission reduction certificate obtained by the target building is determined according to the mutual recognition factor and the green power consumption amount of the target building, including: obtaining the green power consumption amount of the target building; determining the number of certificates obtained by the target building based on the green power consumption amount and the mutual recognition factor using a third formula, wherein the third formula is: P mr,d+1 =η mr P green,d , η mr represents the mutual recognition factor, P green,d represents the amount of green electricity consumed by the target building on day d, P mr,d+1 Represents the number of vouchers obtained by the target building on day d+1.

[0056] Specifically, the number of CCERs (i.e., the number of certificates) obtained by the target building on the day can be obtained based on the green electricity consumed by the target building on the previous day. For example, it is assumed that the green electricity consumed by the target building on day d can be converted into CCER for trading or retained for performance on day d+1. Assuming that the amount of green electricity consumed by the target building on day d is P green,d The mutual recognition factor obtained in step S204 is η mr , can be taken as 0.8042, then the number of CCERs obtained by the target building on day d+1 is P mr,d+1 =η mr P green,d .

[0057] It should be noted that all specific values ​​involved in the embodiments provided in the present invention are only provided as optional examples. In specific applications, more appropriate values ​​can be selected based on actual conditions, and no specific limitations are made here.

[0058] Step S208, with the goal of maximizing the carbon market benefits of the target building, generates a division strategy for dividing the number of certificates into a first certificate number and a second certificate number, wherein the first certificate number is the number of certified emission reduction certificates directly sold by the target building, and the second certificate number is the number of certified emission reduction certificates used by the target building to offset its own carbon emissions.

[0059] In this embodiment, for mandatory buildings, income can be obtained by directly selling the CCERs obtained, or by using CCERs to offset their own carbon emissions, and the remaining carbon quotas can be sold to obtain benefits; for emission reduction buildings and zero-carbon buildings, income is mainly obtained by selling the CCERs obtained. Of course, for emission reduction buildings and zero-carbon buildings, a certain amount of CCERs will also be used to offset their own carbon emissions; therefore, in order to maximize the income of the target buildings as much as possible, the number of CCERs obtained by the target buildings can be reasonably divided, and it can be determined how many CCERs will be sold directly and how many CCERs will be used to offset their own carbon emissions, on the premise of complying with the mutual recognition rules of green electricity consumption and the carbon market.

[0060] According to the above embodiment of the present invention, in the above step S208, a division strategy for dividing the number of vouchers into a first number of vouchers and a second number of vouchers is generated with the goal of maximizing the carbon market revenue of the target building, including: constructing a trading model for the target building to conduct carbon market transactions; iteratively solving the trading model until the iteration termination condition is reached, and determining the candidate solution currently output as the optimal solution of the trading model, wherein the iteration termination condition at least includes: the number of iterations reaches a preset number of iterations, the candidate solution meets the accuracy requirement, and the optimal solution is to achieve the optimal solution for the solution of the objective function in the trading model under the premise of satisfying the constraints; determining a first value of the first number of vouchers and a second value of the second number of vouchers when the carbon market revenue of the target building is maximized according to the optimal solution; determining a strategy for dividing the number of vouchers into a first number of vouchers and a second number of vouchers according to the first value and the second value as the division strategy.

[0061] In this embodiment, a trading model for the target building to conduct carbon market transactions can be constructed based on the mutual recognition technology, and then the corresponding algorithm or linear programming method is used to iteratively solve the trading model to solve the optimal solution that maximizes the benefit of the target building, that is, the number of CCERs used for direct sale (the first certificate number) and the number of CCERs used to offset its own carbon emissions (the second certificate number), so as to determine the division strategy for the CCERs obtained by the target building; when iteratively solving the trading model, it can be judged whether the current solution is the optimal solution based on whether the iteration termination condition is met. Generally speaking, the iteration termination condition can be whether the current number of iterations has reached a preset maximum number of iterations, or whether the candidate solution currently output meets the accuracy requirements, that is, whether its error is less than the error threshold. Of course, other conditions can also be set as conditions for terminating the iteration of the trading model, and no specific restrictions are made here.

[0062] In the above embodiment of the present invention, constructing a trading model for a target building to conduct carbon market trading includes: establishing an objective function with the goal of maximizing the carbon market revenue of the target building, wherein the expression of the objective function is: R force represents the carbon market income, d represents the number of days, D represents the total number of days in the target time period, and P CEA,d represents the carbon emission quota trading volume on day d, C CEA,d represents the market price of carbon emission quota on day d, P CCER,d represents the transaction volume of certified emission reduction certificates on day d, C ,d represents the market price of the certified emission reduction certificate on the dth day; multiple constraints are obtained according to the mutual recognition rules that the target building must comply with when mutual recognition is carried out in the green electricity consumption and carbon market, wherein the constraints include at least: a first constraint that is constrained by the coupling between the mutual recognition volume and the trading volume of the certified emission reduction certificate, a second constraint that is constrained by the total amount of compliance of the certified emission reduction certificate, a third constraint that is constrained by the number of carbon emission quotas, a fourth constraint that is constrained by the saleable number of the certified emission reduction certificate, a fifth constraint that is constrained by the total amount of compliance of the target building during the compliance period, and a sixth constraint that is constrained by the transaction capital flow; a trading model is constructed according to the objective function and multiple constraints.

[0063] Specifically, in the trading models constructed for different types of buildings, there will be slight differences in the objective functions and constraints. The trading models for mandatory buildings, emission-reduction buildings, and zero-carbon buildings are explained below.

[0064] For mandatory buildings, the carbon quota allocation model is: CEAneed =P cf η cf , P CEAfree =ωP CEAneed , where P CEAneed The amount of carbon quotas required for contract performance settlement, P cf is the thermal power consumption, η cf is the regional thermal power carbon emission factor, which can be 0.8729, P CEAfree is the number of free quotas, ω is the proportion of free quotas, which is 95%; the mutual recognition model is: P mr,d+1 =η mr P green,d , η mr represents the mutual recognition factor, P green,d represents the amount of green electricity consumed by the target building on day d, P mr,d+1 It represents the number of CCERs obtained by the target building on day d+1. The objective function of the trading model is: R forcerepresents the carbon market revenue of mandatory buildings based on mutual recognition technology, d represents the number of days, D represents the total number of days in the target time period, and P CEA,d represents the carbon emission quota trading volume on day d, C CEA,d represents the market price of carbon emission quota on day d, P CCER,d represents the transaction volume of certified emission reduction certificates on day d, C ,d represents the market price of the certified emission reduction certificate on the dth day; the constraints of the trading model include: 1) the coupling constraint between the mutual recognition volume and the CCER trading volume: 2) Constraints on the total amount of CCER that can be fulfilled: 3) Constraints on the total amount of CEA (carbon emission quota) that can be sold: 4) Constraints on the total amount of CCER that can be sold: 5) Total performance constraints: 6) Trading capital flow constraints: P CEA,b, d C CEA,d +P CCER,b,d C CCER,d ≤fund, where P CCER is the total amount of mutually recognized CCER; α CCER The CCER offset ratio is set at 10%; CEA,b,d The amount of carbon quota purchased for the building entity on day d, P CCER,b,d is the amount of CCER purchased by the building entity on day d, and fund is the transaction capital flow constraint of the building entity.

[0065] For emission reduction buildings, the mutual recognition model is the same as that for mandatory buildings, and the objective function of the transaction model is: In the formula, R LC Carbon market benefits for emission-reducing buildings based on mutual recognition technology; the constraints of the trading model include: 1) Coupling constraints between mutual recognition volume and CCER trading volume: 2) Constraints on the total amount of CCER that can be sold: 3) Trading capital flow constraints: P CCER,b,d C CCER,d ≤fund.

[0066] For zero-carbon buildings, the mutual recognition model is the same as that for mandatory buildings, and the objective function of the transaction model is: In the formula, R ZC Carbon market benefits for zero-carbon buildings based on mutual recognition technology; the constraints of the trading model include: 1) Coupling constraints between mutual recognition volume and CCER trading volume: 2) Constraints on the total amount of CCER that can be sold: 3) Trading capital flow constraints: P CCER,b,d CCCER,d ≤fund; 4) Total performance constraints:

[0067] Step S210, controlling the target building to divide the number of vouchers according to the division strategy and then conduct carbon market transactions, so as to maximize the carbon market income of the target building under the premise of satisfying the constraint conditions.

[0068] In this embodiment, as above Figure 3 As shown, the target building is controlled to divide the number of certificates according to the division strategy and then conduct carbon market transactions based on the mutual recognition technology, so as to maximize the carbon market benefits of the target building while meeting the constraints.

[0069] From the above, it can be seen that through the technical solution provided by the above embodiment of the present invention, the electricity-carbon mutual recognition mechanism of the target building when the green electricity consumption and the carbon market are mutually recognized can be determined, wherein the electricity-carbon mutual recognition mechanism is used to represent the mechanism by which the target building obtains carbon emission reductions recognized by the carbon market by consuming green electricity; the mutual recognition factor of the target building when the green electricity consumption and the carbon market are mutually recognized is determined according to the electricity-carbon mutual recognition mechanism, wherein the mutual recognition factor is the exchange coefficient between the green electricity consumption and the carbon emission reduction when mutual recognition is carried out; the number of certificates of certified emission reduction certificates obtained by the target building is determined according to the mutual recognition factor and the green electricity consumption of the target building, wherein the certified emission reduction certificate is a certificate used to offset a predetermined amount of carbon emission reductions; the number of certificates is divided into a first certificate number and a second certificate number with the goal of maximizing the carbon market benefits of the target building. A division strategy is proposed, in which the first certificate quantity is the quantity of certified emission reduction certificates directly sold by the target building, and the second certificate quantity is the quantity of certified emission reduction certificates used by the target building to offset its own carbon emissions; the target building is controlled to divide the certificate quantity according to the division strategy and then conduct carbon market transactions, so that the carbon market income of the target building is maximized under the premise of meeting the constraints, and the purpose of analyzing the mutual recognition mechanism of the building is achieved, and based on the mutual recognition mechanism, the building entity conducts green electricity consumption and carbon market mutual recognition, thereby increasing the carbon market income of the building entity, and realizes the technical effect of enabling various building entities to conduct carbon market transactions by utilizing mutual recognition technology, so as to maximize the carbon market income of the building entity under the premise of meeting the constraints, which helps to reduce the emission reduction pressure of various buildings and effectively promotes the enthusiasm of building entities to participate in carbon market transactions.

[0070] Therefore, the technical solution provided by the above-mentioned embodiment of the present invention solves the technical problem that the existing mutual recognition mechanism is usually concentrated in the power generation field, lacks a mutual recognition method based on buildings, and leads to poor carbon market trading efficiency of buildings based on mutual recognition technology.

[0071] Combine the following Figure 4 , Figure 5 and Figure 6 The above embodiments of the present invention are described in detail. Figure 4 is a schematic diagram of market transaction results based on mutual recognition of emission reduction equivalents according to an embodiment of the present invention; Figure 5 is a schematic diagram of market transaction results based on mutual recognition of environmental benefits according to an embodiment of the present invention; Figure 6 is a schematic diagram of comparing the trading results of the mandatory building carbon market according to an embodiment of the present invention.

[0072] Taking one month as an example, carbon market trading simulation is carried out for mandatory buildings, emission reduction buildings, and zero-carbon buildings, and the simulation results are as follows: Figure 4 and Figure 5 As shown; the purpose of mandatory building transactions is to make the number of carbon quotas and CCERs held at the time of performance equal to the number of its own carbon emissions. Due to the existence of mutual recognition technology, the number of CCERs held by this type of entity increases. Since the free quota allocation ratio is 95% and the CCER performance ratio is 10%, this type of building entity can obtain income by selling a certain amount of carbon quotas and trading a certain amount of CCER, that is, mutual recognition technology brings additional income to mandatory buildings and reduces the performance burden of emission control entities; emission reduction buildings obtain market rewards for their own emission reduction behaviors through CCER mutual recognition, and can obtain income by selling CCER; zero-carbon buildings need to ensure their own carbon emissions are zero due to the existence of zero-carbon goals. Through mutual recognition technology, the green electricity they consume can be converted into emission reductions, reducing their own zero-carbon pressure; the emission reduction needs of the three types of building entities are different, resulting in differences in trading situations.

[0073] Mandatory buildings trade carbon quotas and CCERs in the carbon market. The trading results are as follows: Figure 6 As shown, the increase in self-consumption of green electricity means an increase in the number of CCERs. Within the limit of the CCER offset ratio, the surplus carbon quota increases. At the same time, since the market price of carbon quotas is generally higher than that of carbon quotas, there is a tendency to give priority to selling surplus carbon quotas to benefit; emission-reduction buildings have little pressure to reduce emissions, participate in the carbon market through profit-driven means, and only trade CCERs in the carbon market; zero-carbon buildings have greater pressure to reduce emissions. In order to achieve carbon neutrality, they need to purchase CCERs to offset the carbon emissions of their own consumption of traditional electricity. Therefore, the overall trading behavior in the carbon market is reflected in the purchase of CCERs.

[0074] Comparing the benefits of the three types of building entities with and without mutual recognition technology, the results are shown in Table 1 below. Table 1 shows the comparison of the benefits of the three types of building entities.

[0075] Table 1

[0076]

[0077] By comparing the trading situations of the two mutual recognition technologies, it can be seen that the difference in mutual recognition technologies will lead to different CCER mutual recognition results. The mutual recognition quantity of CCER provided by the mutual recognition technology based on emission reduction equivalents follows the green electricity consumption of the building entity, while the mutual recognition results corresponding to the mutual recognition technology based on environmental benefits do not follow the situation in some areas, which increases the uncertainty of transaction decisions. And because the mutual recognition factor in the mutual recognition technology based on environmental benefits is derived from the ratio of the CCER market price to the green certificate price, which is larger than the mutual recognition factor of the mutual recognition technology based on emission reduction equivalents, the number of mutually recognized CCERs is large, the CCER market sales of various entities have increased, and the purchase volume has decreased. The overall benefits of various entities corresponding to the mutual recognition technology based on environmental benefits are greater than those corresponding to the mutual recognition technology based on emission reduction equivalents.

The purpose of analyzing the mutual recognition mechanism of the building is achieved, and based on the mutual recognition mechanism, the building entity conducts green electricity consumption and carbon market mutual recognition, thereby increasing the carbon market income of the building entity. The technical effect of maximizing the carbon market income of the building entity under the premise of meeting the constraints is achieved by utilizing mutual recognition technology to enable various building entities to conduct carbon market transactions, which helps to reduce the emission reduction pressure of various buildings and effectively promotes the enthusiasm of building entities to participate in carbon market transactions.
