Description

Technical Field

[0001] This invention relates to the field of carbon trading technology, and in particular to a method for the mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions. Background Technology

[0002] With rapid economic growth, my country's energy consumption and carbon emissions have risen sharply, making the carbon emission problem increasingly serious. Currently, my country's energy sector has formed a pattern of parallel market mechanisms including green electricity trading, green certificate trading, and carbon trading. Achieving effective integration between the carbon market and the green certificate market, promoting the complementary advantages of carbon quotas, green certificates, and Chinese certified emission reductions (CCERs), and increasing the application scenarios for various environmental certificates are among the current directions for the optimized development of the carbon market and the green certificate market.

[0003] Currently, multiple policies exist concurrently in the green electricity sector, but the barriers between these policies are unclear, the boundaries between environmental rights products are blurred, and the responsibilities of management are redundant. This poses risks such as duplicate certification and multiple issuance of environmental rights for clean and green electricity. For example, China's energy sector has formed a pattern of parallel market mechanisms such as green electricity trading, green certificate trading, and carbon trading. Each kilowatt-hour of green electricity can participate in green electricity trading and generate green certificates, while simultaneously applying for nationally certified voluntary emission reductions to participate in carbon trading. This results in the problem of duplicate recognition of environmental rights, urgently requiring clarification of the relationships between various policies, the development of reasonable electricity-carbon mutual recognition technologies, the improvement of the green electricity policy system, and the enhancement of information channels between various markets.

[0004] Currently, in addition to the issue of duplicate recognition of green certificates and CCERs, there is also the problem of duplicate recognition of carbon emissions from electricity generation and consumption. Due to the neglect of source tracing and energy flow relationships, duplicate certification of carbon emissions from electricity generation and consumption has led to risks such as duplicate issuance of environmental rights certifications for clean and green electricity and duplicate penalties for carbon emissions. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a method for the mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions (CCERs). This method ensures the fairness and effectiveness of CCER allocation, promotes the low-carbon transformation of the power system, and incentivizes users to actively participate in the consumption of renewable energy.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] According to a first aspect of the present invention, a method for mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions is provided, comprising:

[0008] S1. Construct a virtual power plant in a park-type area to act as an intermediary for user entities with different emission reduction characteristics;

[0009] S2. Revise the original power factor by deducting the amount of new energy generation from the total electricity output;

[0010] S3. Based on the principle of the uniqueness of environmental rights and the polluter pays principle, mutual recognition of national certified voluntary emission reductions (CCERs) and green electricity shall be made in accordance with the revised electricity factor.

[0011] S4. The park-type virtual power plant agents uniformly claim the national certified voluntary emission reductions.

[0012] S5. The multi-weighted Shapley value method is used to allocate nationally certified voluntary emission reductions.

[0013] Preferably, the user groups with different emission reduction characteristics in S1 include nationally mandated emission reduction users, voluntary emission reduction users, and zero-carbon emission users, wherein:

[0014] The nationally mandated emission reduction users are located in the government-controlled emission list and hold a certain number of free allowances each year. The green electricity consumed can be mutually recognized as nationally certified voluntary emission reductions to make up for the shortfall in allowances. Both surplus and deficit allowances can be traded in the carbon market within the park-type virtual power plant.

[0015] The aforementioned voluntary emission reduction users are not subject to mandatory emission reduction requirements. The green electricity generated and consumed by the users can be mutually recognized as nationally certified voluntary emission reductions and traded in the carbon market within the park-type virtual power plant.

[0016] The thermal power consumed by the zero-carbon emission users must be offset by obtaining an equivalent amount of nationally certified voluntary emission reductions (CCERs) through carbon market trading within the park-type virtual power plant.

[0017] Preferably, the use of a park-type virtual power plant as an intermediary agent satisfies the following boundaries:

[0018] 1) In the park-type virtual power plant, the mutual recognition cycle of national certified voluntary emission reductions (CCERs) is daily. The green electricity consumed by the user on day d is mutually recognized as national certified voluntary emission reductions (CCERs) and traded on day d+1. The electricity market is an hourly spot market, and the carbon market is a daily spot market.

[0019] 2) The national certified voluntary emission reduction certificates corresponding to the green electricity consumption emission reduction of user entities must be applied for through the park-type virtual power plant as an agent, and then issued to each user entity within the park-type virtual power plant;

[0020] 3) Carbon quotas and nationally certified voluntary emission reductions (CCERs) share a carbon price and are traded equally in the market without distinction.

[0021] Preferably, in step S2, the original power factor is revised by deducting the renewable energy generation from the total electricity output, and the calculation expression is as follows:

[0022]

[0023] In the formula: ξ * C is the revised power factor. A ∑P represents total emissions; ∑P represents total power generation; ∑P NEW ξ represents the amount of electricity generated from new energy sources; ξ represents the original electricity emission factor.

[0024] Preferably, in step S3, based on the principles of the uniqueness of environmental rights and the polluter-pays principle, green electricity and nationally certified voluntary emission reductions (CCERs) are mutually recognized according to the revised electricity factor, specifically including:

[0025] Based on the green electricity trading model that combines certificates and electricity, the environmental rights of green electricity are transferred to the user side along with the green electricity. At this time, renewable energy generators no longer have the right to recognize the national certified voluntary emission reductions corresponding to green electricity. Instead, the user side applies for the national certified voluntary emission reduction certificates corresponding to green electricity.

[0026] Based on the principle of equivalent emission reduction, and according to regional carbon emission factors, the mutual recognition of green electricity and nationally certified voluntary emission reductions (CCERs) is carried out. The amount of CCERs obtained through this mutual recognition is M. CCER for:

[0027] M CCER =p green ξ * (2)

[0028] In the formula: p green For users' green electricity consumption; ξ * This is the revised power factor.

[0029] Preferably, in S4, the park-type virtual power plant agent uniformly claims the national certified voluntary emission reductions. The green electricity calculated by the park-type virtual power plant includes green electricity purchased from external green electricity trading and green electricity generated and used by internal users. The green electricity generated and used by internal users includes green electricity generated and used by users themselves and green electricity supplied to other users within the park-type virtual power plant.

[0030] Preferably, in S5, the national certified voluntary emission reductions mutually recognized by the park-type virtual power plant include the national certified voluntary emission reductions corresponding to the green electricity generated and consumed by the user and the national certified voluntary emission reductions corresponding to the electricity traded between the user and the park-type virtual power plant.

[0031] The nationally certified voluntary emission reductions corresponding to the green electricity generated and consumed by the user entity are directly issued after being applied for by the park-type virtual power plant; the nationally certified voluntary emission reductions corresponding to the electricity traded between the user entity and the park-type virtual power plant are allocated using the multi-weight Shapley value method.

[0032] Preferably, the nationally certified voluntary emission reductions corresponding to the electricity traded between the user entity and the virtual power plant are allocated using a multi-weighted Shapley value method, specifically:

[0033] (1) Calculate the mutual recognition amount of nationally certified voluntary emission reductions for virtual power plants, using the following expression:

[0034]

[0035] Where: M PVPP,d For the virtual power plant, the nationally certified voluntary emission reduction mutual recognition amount on day d; I represents the set of user entities within the park-type virtual power plant; T represents the intraday period. The amount of green electricity generated by user subject i at time t on day d-1; For user subject i, at time t on day d-1, the park-type virtual power plant sells electricity to the grid. For user subject i, at time t on day d-1, the park-type virtual power plant purchases electricity. The green power factor is the power flow of electricity from the virtual power plant in the park-type power grid at time t on day d-1.

[0036] (2) The mixed electricity surplus from the external power grid and internal users is allocated using the multi-weight Shapley value method, where the mutual recognition utility function of the park-type virtual power plant alliance is:

[0037]

[0038] In the formula: S is the current alliance set of park-type virtual power plants; ν(S) is the utility of the current alliance set S of park-type virtual power plants, representing the mutually recognized national certified voluntary emission reductions; and These represent the electricity sold to and purchased from the grid by the virtual power plant in the park at time t on a typical day d'.

[0039] (3) Calculate the Shapley value Φ of the national certified voluntary emission reduction allocated to user subject i. i The expression is:

[0040]

[0041] In the formula: N is the total number of user entities within the park-type virtual power plant; s is the number of user entities within the park-type virtual power plant alliance S; ν(S-{i}) is the utility of the park-type virtual power plant alliance after removing user entity i;

[0042] (4) Based on the Shapley equivalence decomposition theorem, calculate the multi-weighted Shapley value of the national certified voluntary emission reduction (CCER) allocated to user subject i. The expression is:

[0043]

[0044] In the formula: λ i S is a constant factor of user subject i; j A substantial alliance of no fewer than two; ω ji S represents j The weight of user subject i in the middle; μ j It is S j The constant factor;

[0045] (5) The multi-weighted Shapley value of the national certified voluntary emission reduction (CCER) allocated to user subject i. Calculate the multi-weight Shapley value allocation coefficient k for user subject i. i :

[0046]

[0047] (6) Assign coefficient k based on the multi-weight Shapley value of user subject i. i Calculate the nationally certified voluntary emission reductions (CCERM) allocated to user subject i on day d. i,d :

[0048] M i,d =M i,self,d +k i ΔM PVPP,d (9)

[0049] Where: M i,self,d For user entity i, the mutual recognition of nationally certified voluntary emission reductions (CCERs) for self-generated and self-consumed green electricity on day d; ΔM PVPP,d This refers to the mutually recognized national certified voluntary emission reductions (CCERs) on day d of the virtual power plant (PVPP) in the industrial park, excluding green electricity generated and consumed by the main user entity.

[0050] According to a second aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement any of the methods described above.

[0051] According to a third aspect of the invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements any of the methods described herein.

[0052] Compared with the prior art, the present invention has the following beneficial effects:

[0053] (1) Based on the principle of the uniqueness of environmental rights and the polluter pays principle, this invention starts from the underlying logic of carbon emission rights and green electricity trading, and proposes a method for mutual recognition of emission reductions of national certified voluntary emission reductions (CCERs) and green electricity. The purpose of transferring the emission reduction effectiveness and pollution responsibility to the user side is to solve the problems of double counting of emission reductions and unclear responsibility caused by the parallel operation of the current carbon market and green electricity market.

[0054] (2) This invention proposes an alliance composed of park-type virtual power plants (PVPP) as the main users, and uses PVPP as agents to apply for CCERs to avoid the problem of increased recognition workload caused by mutual recognition of individual users and the problem that some users are too small to meet the mutual recognition threshold.

[0055] (3) The green electricity purchased by the user from the park-type virtual power plant PVPP is a mixture of electricity from the external power grid and the internal user surplus. As a homogeneous commodity, electricity cannot be distinguished by physical means after being mixed at the grid connection point. Moreover, the existing smart meters can only measure the total electricity and cannot identify the proportion of green electricity. This invention uses the multi-weight Shapley value method to allocate the national certified voluntary emission reduction (CCER) obtained by mutual recognition of the mixed electricity. This overcomes the problem that the mixed electricity cannot be accurately measured and the traditional Shapley value method unilaterally emphasizes the marginal contribution. It fully considers the different emission reduction pressures faced by different types of users. Attached Figure Description

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0060] Example 1

[0061] This embodiment is based on a park-type virtual power plant (PVPP) containing multiple types of user entities, with the user entity set being {f1,f2,z3,z4,k5,k6}. f1 and f2 correspond to users subject to mandatory national emission reductions, z3 and z4 correspond to users subject to voluntary emission reductions, and k5 and k6 correspond to users subject to zero carbon emissions. The baseline emission factor for carbon dioxide in this region is 0.583 tCO2 / MWh. A method for mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions (CCERs) is presented to allocate the CCERs that each user entity within the park-type virtual power plant (PVPP) can obtain.

[0062] Set the following boundaries:

[0063] (1) The mutual recognition period of China's Certified Emission Reductions (CCERs) in the PVPP (Virtual Power Plant in Parks) is taken as the day. Green electricity consumed by the user on day d is mutually recognized as CCERs for trading on day d+1. In addition, the electricity market is an hourly spot market and the carbon market is a daily spot market.

[0064] (2) The national certified voluntary emission reduction (CCER) certificates corresponding to the green electricity consumption emission reduction of user entities must be applied for through the park-type virtual power plant (PVPP) as an agent, and then distributed to each internal user entity.

[0065] (3) Since carbon quotas and national certified voluntary emission reductions (CCERs) have the same carbon emission compliance effect, in order to simplify the complexity of the carbon market, they are no longer distinguished in the market and are traded on an equal footing, that is, the two types of objects share a carbon price.

[0066] like Figure 1 and Figure 2 As shown, the method specifically includes the following steps:

[0067] S1. Construct a virtual power plant in a park-like area to act as an intermediary for user entities with different emission reduction characteristics.

[0068] In this embodiment, the study focuses on users, categorizing them into three types based on their emission reduction characteristics: mandatory national emission reduction users, voluntary emission reduction users, and zero-carbon emission users.

[0069] (1) National mandatory emission reduction users: located in the government's emission control list, with a large carbon emission base, holding a certain number of free allowances each year. The green electricity they consume can be mutually recognized as national certified voluntary emission reductions (CCERs) to fill the quota shortage. At the same time, the surplus and deficit can be traded in the carbon market within the park-type virtual power plant (PVPP).

[0070] (2) Self-generated emission reduction users: No mandatory emission reduction requirements are imposed. They generally have their own small power generation equipment. Their self-generated and self-consumed green electricity can be mutually recognized as national certified voluntary emission reductions (CCERs) and traded in the carbon market within the park-type virtual power plant (PVPP).

[0071] (3) Zero-carbon emission users: In order to fulfill their commitment to zero carbon emissions, these users need to offset the traditional thermal power they consume by obtaining an equivalent amount of national certified voluntary emission reductions (CCERs) through carbon market trading within the park-type virtual power plant (PVPP).

[0072] S2. The original power factor is revised by deducting the power generation of new energy sources such as wind and solar power from the total power generation. The revised power factor ξ * .

[0073] In this embodiment, the revised power factor ξ * The expression is:

[0074]

[0075] In the formula: C A ∑P represents total emissions; ∑P represents total power generation; ∑P NEW ξ represents the amount of electricity generated from new energy sources; ξ represents the original electricity emission factor.

[0076] S3. Based on the principles of the uniqueness of environmental rights and the polluter-pays principle, and tracing back to the source, a green electricity trading model integrating certification and electricity is proposed. This model uses the principle of equivalent emission reduction, and mutual recognition of nationally certified voluntary emission reductions (CCERs) and green electricity emission reductions according to the revised electricity factor. This transfers the effectiveness of emission reductions and pollution responsibility to the user side for assessment. Specifically, this includes:

[0077] Based on the green electricity trading model that integrates certificates and electricity generation, the environmental rights of green electricity are transferred to the user side along with the green electricity. That is, renewable energy generators no longer enjoy the right to be recognized by the national certified voluntary emission reduction (CCER) corresponding to green electricity, and the user side applies for the consumption of the CCER certificate corresponding to green electricity.

[0078] Based on the principle of equivalent emission reduction, mutual recognition of green electricity and nationally certified voluntary emission reductions (CCERs) is carried out according to regional carbon emission factors. The CCER amount M obtained through mutual recognition is... CCER for:

[0079] M CCER =p green ξ * (2)

[0080] In the formula: p green For users' green electricity consumption; ξ * This refers to the revised power factor, also known as the mutual recognition factor.

[0081] S4. The park-type virtual power plant PVPP acts as an alliance of user entities to apply for national certified voluntary emission reduction credits (CCERs) and then distributes them to internal users.

[0082] The green electricity calculated by the PVPP (Virtual Power Plant Project) in the industrial park includes:

[0083] (1) Green electricity purchased through external green electricity trading;

[0084] (2) Green electricity that is spontaneously used by internal users, including green electricity that is spontaneously used by users and green electricity that is supplied to other users within the PVPP.

[0085] S5. The national certified voluntary emission reductions (CCERs) mutually recognized by PVPP agents in park-type virtual power plants are divided into national certified voluntary emission reductions (CCERs) corresponding to green electricity generated and consumed by users and national certified voluntary emission reductions (CCERs) corresponding to the electricity traded between users and PVPP agents in park-type virtual power plants.

[0086] like Figure 3 As shown, the green electricity generated and consumed by the user is measured by smart meters, and the corresponding national certified voluntary emission reductions (CCERs) are directly issued by the park-type virtual power plant (PVPP).

[0087] The green electricity portion of the electricity traded between user entities and park-type virtual power plants (PVPPs) consists of a mixture of surplus electricity from the external grid and internal users. The corresponding national certified voluntary emission reductions (CCERs) for this portion of green electricity are allocated using the multi-weighted Shapley value method, which includes the following steps:

[0088] (1) Calculate the national certified voluntary emission reduction (CCER) mutual recognition amount for park-type virtual power plants (PVPP):

[0089]

[0090] Where: M PVPP,d For the day d of the park-type virtual power plant (PVPP), the amount of China Certified Emission Reduction (CCER) mutual recognition amount is; I is the set of user entities within the park-type virtual power plant (PVPP); T is the intraday period, taken as 24 hours. The amount of green electricity generated by user subject i at time t on day d-1; For user subject i, at time t on day d-1, the park-type virtual power plant (PVPP) sells electricity to the grid. For user subject i, at time t on day d-1, the park-type virtual power plant (PVPP) purchases electricity; The green power factor for the power flow of the virtual power plant (PVPP) entering the power grid at time t on day d-1 is obtained based on power flow tracking technology and carbon emission flow theory.

[0091] (2) Calculate the mutual recognition utility ν(S) of the current alliance set S of the park-type virtual power plant PVPP, that is, the mutual recognition of national certified voluntary emission reductions (CCERs):

[0092]

[0093] In the formula: S is the current alliance set of the virtual power plant (PVPP) in the park, which is a subset of the total members; and These represent the electricity sold and purchased by the PVPP to the grid at time t on a typical day d'.

[0094] (3) Calculate the multi-weighted Shapley value of the national certified voluntary emission reduction (CCER) allocated to the user entity.

[0095] Calculate the Shapley value Φ of the national certified voluntary emission reductions (CCERs) allocated to user subject i. i :

[0096]

[0097] In the formula: N is the total number of user entities within the park-type virtual power plant PVPP; s is the number of user entities within the park-type virtual power plant PVPP alliance S; ν(S-{i}) is the utility of the park-type virtual power plant PVPP alliance after removing user entity i.

[0098] Shapley's equivalent decomposition theorem:

[0099]

[0100] In the formula: λ i S is a constant factor of user subject i; j A substantial alliance of no fewer than two; μ j It is S j The constant factor.

[0101] Calculate the multi-weighted Shapley value for user subject i to allocate nationally certified voluntary emission reductions (CCERs).

[0102]

[0103] In the formula: λ i S is a constant factor of user subject {i}; j A substantial alliance of no fewer than two; ω ji S represents j The weight of user subject i in the middle; μ j It is S j The constant factor.

[0104] (4) The multi-weighted Shapley value of the national certified voluntary emission reduction (CCER) allocated to user subject i. Calculate the multi-weight Shapley value allocation coefficient k for user subject i. i :

[0105]

[0106] (5) Assign coefficient k based on the multi-weight Shapley value of user subject i. i Calculate the nationally certified voluntary emission reductions (CCERM) allocated to user subject i on day d. i,d :

[0107] M i,d =M i,self,d +k i ΔM PVPP,d (9)

[0108] Where: M i,self,d For user entity i, the mutual recognition of nationally certified voluntary emission reductions (CCERs) for self-generated and self-consumed green electricity on day d; ΔM PVPP,d This refers to the mutually recognized national certified voluntary emission reductions (CCERs) on day d of the virtual power plant (PVPP) in the industrial park, excluding green electricity generated and consumed by the main user entity.

[0109] This invention, based on the principles of the uniqueness of environmental rights and the polluter-pays principle, uniformly assigns the environmental rights of green electricity to the user side, thereby avoiding double counting of environmental rights. The research focuses on the user as the primary subject. First, users are categorized into three types—mandatory users, emission-reduction users, and zero-carbon users—based on their different emission reduction characteristics. Using a virtual power plant in a power park as an agent, under a "certificate-electricity integration" green electricity trading model, mutual recognition of green electricity and nationally certified voluntary emission reductions (CCERs) is achieved based on the principle of equivalent emission reductions and according to regional carbon emission factors. Then, addressing the allocation of CCERs within the virtual power plant in the power park, a multi-weighted Shapley value method is proposed. Ultimately, through these steps, the mutual recognition and allocation of green electricity and CCERs can be completed, achieving electricity-carbon linkage. This protects the interests of both the power generation and user sides, promotes the green development of the power system, and drives users to actively consume green electricity.

The method for mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions according to claim 1, characterized in that, Based on the principles of the uniqueness of environmental rights and the polluter-pays principle, S3 stipulates mutual recognition of green electricity and nationally certified voluntary emission reductions (CCERs) according to the revised electricity factor, specifically including: Based on the green electricity trading model that combines certificates and electricity, the environmental rights of green electricity are transferred to the user side along with the green electricity. At this time, renewable energy generators no longer have the right to recognize the national certified voluntary emission reductions corresponding to green electricity. Instead, the user side applies for the national certified voluntary emission reduction certificates corresponding to green electricity. Based on the principle of equivalent emission reduction, and according to regional carbon emission factors, the mutual recognition of green electricity and nationally certified voluntary emission reductions (CCERs) is carried out. The amount of CCERs obtained through this mutual recognition is M. CCER for: M CCER =p green x * (2) In the formula: p green For users' green electricity consumption; ξ * This is the revised power factor.

6. The method for mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions according to claim 1, characterized in that, In S4, the park-type virtual power plant agent uniformly claims the national certified voluntary emission reductions. The green electricity calculated by the park-type virtual power plant includes green electricity purchased from external green electricity trading and green electricity generated and used by internal users. The green electricity generated and used by internal users includes green electricity generated and used by users themselves and green electricity supplied to other users within the park-type virtual power plant.

7. A method for mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions according to claim 6, characterized in that, In S5, the national certified voluntary emission reductions recognized by the agency of the park-type virtual power plant include the national certified voluntary emission reductions corresponding to the green electricity generated and consumed by the user and the national certified voluntary emission reductions corresponding to the electricity traded between the user and the park-type virtual power plant. The nationally certified voluntary emission reductions corresponding to the green electricity generated and consumed by the user entity are directly issued after being applied for by the park-type virtual power plant; the nationally certified voluntary emission reductions corresponding to the electricity traded between the user entity and the park-type virtual power plant are allocated using the multi-weight Shapley value method.

8. The method for mutual recognition and allocation of green electricity and nationally certified voluntary emission reductions according to claim 7, characterized in that, The nationally certified voluntary emission reductions corresponding to the electricity traded between the user entity and the virtual power plant are allocated using the multi-weighted Shapley value method, specifically: (1) Calculate the mutual recognition amount of nationally certified voluntary emission reductions for virtual power plants, using the following expression: Where: M PVPP,d For the virtual power plant, the nationally certified voluntary emission reduction mutual recognition amount on day d; I represents the set of user entities within the park-type virtual power plant; T represents the intraday period. The amount of green electricity generated by user subject i at time t on day d-1; For user subject i, at time t on day d-1, the park-type virtual power plant sells electricity to the grid. For user subject i, at time t on day d-1, the park-type virtual power plant purchases electricity. The green power factor is the power flow of electricity from the virtual power plant in the park-type power grid at time t on day d-1. (2) The mixed electricity surplus from the external power grid and internal users is allocated using the multi-weight Shapley value method, where the mutual recognition utility function of the park-type virtual power plant alliance is: In the formula: S is the current alliance set of park-type virtual power plants; ν(S) is the utility of the current alliance set S of park-type virtual power plants, representing the mutually recognized national certified voluntary emission reductions; and These represent the electricity sold to and purchased from the grid by the virtual power plant in the park at time t on a typical day d'. (3) Calculate the Shapley value Φ of the national certified voluntary emission reduction allocated to user subject i. i The expression is: In the formula: N is the total number of user entities within the park-type virtual power plant; s is the number of user entities within the park-type virtual power plant alliance S; ν(S-{i}) is the utility of the park-type virtual power plant alliance after removing user entity i; (4) Based on the Shapley equivalence decomposition theorem, calculate the multi-weighted Shapley value of the national certified voluntary emission reduction (CCER) allocated to user subject i. The expression is: In the formula: λ i S is a constant factor of user subject i; j A substantial alliance of no fewer than two; ω ji S represents j The weight of user subject i in the middle; μ j It is S j The constant factor; (5) The multi-weighted Shapley value of the national certified voluntary emission reduction (CCER) allocated to user subject i. Calculate the multi-weight Shapley value allocation coefficient k for user subject i. i : (6) Assign coefficient k based on the multi-weight Shapley value of user subject i. i Calculate the nationally certified voluntary emission reductions (CCERM) allocated to user subject i on day d. i,d : M i,d = M i,self,d +k i ΔM PVPP,d (9) Where: M i,self,d For user entity i, the mutual recognition of nationally certified voluntary emission reductions (CCERs) for self-generated and self-consumed green electricity on day d; ΔM PVPP,d This refers to the mutually recognized national certified voluntary emission reductions (CCERs) on day d of the virtual power plant (PVPP) in the industrial park, excluding green electricity generated and consumed by the main user entity.
