At the same time, green power certificates can be used as the only proof of green power transactions and as a certificate for deducting carbon emission rights, providing a certain basis for the coordinated mutual recognition and coupled transactions between different markets. Therefore, in order to meet the changes in market transaction needs, the coordinated barriers between the three markets of green power, carbon emission rights, and green certificates are opened up, while enhancing the mutual recognition of green environmental attributes, preventing the repeated calculation of green environmental attributes, and facilitating the assessment of the green environmental responsibilities of enterprises.

BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Figure 1 It is a schematic diagram of the system flow of the present invention;

[0051] Figure 2 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0052] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0053] Example 1

[0054] This embodiment provides an electricity-certificate-carbon collaborative trading system based on IOTA technology. Figure 1 As shown, the system includes a data acquisition module 1, a data processing module 2, an IOTA transaction subsystem 3 and a monitoring module 4, and the data processing module 2 is connected to the data acquisition module 1, the IOTA transaction subsystem 3 and the monitoring module 4 respectively.

[0055] The data collection module 1 is used to collect real-time green electricity, green certificates, CCER, carbon quota and other data of each trading entity.

[0056] The data processing module 2 establishes a trading system that meets the needs of all market players, forms a mutual recognition and conversion relationship between green electricity, green certificates, and carbon emission rights, and converts different trading targets in the green electricity, green certificates, and carbon emission rights markets into a unified trading target. Considering that the environmental value of each market is a common attribute, the green environmental attribute is used as a unified trading target, and combined with the target conversion relationship between different markets, a unified green environmental attribute mutual recognition method is established. This module includes a collaborative mutual recognition conversion submodule 21 for the electricity certificate market, a collaborative mutual recognition conversion submodule 22 for the electricity-carbon market, a collaborative mutual recognition conversion submodule 23 for the carbon certificate market, and a unified green environmental attribute value submodule 24 for the electricity-certificate-carbon market.

[0057] Sub-module 21 of the collaborative mutual recognition conversion of the electricity certificate market: The transaction subject of the green electricity market is green electricity. During the production process of green electricity, green certificates will be issued based on the power generation of green electricity. The green certificate is the only proof of the environmental attributes of renewable energy electricity. It is an electronic certificate with a unique identification code issued for green electricity generated by renewable energy power generation projects. Each green certificate unit corresponds to a certain amount of renewable energy electricity. The quantitative conversion relationship between green electricity and green certificates can be defined as:

[0058] Q gc =Q ge / n

[0059] Q ge Indicates the amount of green electricity, Q gc It indicates the amount of green electricity that can be calculated as green certificates, and n indicates the conversion coefficient between green electricity and green certificates.

[0060] Submodule 22 of the coordinated mutual recognition and conversion of the electricity-carbon market: The trading objects of carbon emission rights are carbon emission rights and CCER. The entities that need to purchase carbon emission rights are thermal power generation enterprises and key emission power users. The carbon emissions of thermal power units are related to the power generation of thermal power units. The carbon emissions of key emission power users (i.e. carbon quotas) are related to the purchase of non-green electricity. When the original carbon emission rights are exceeded, carbon emission rights need to be purchased in the market. According to national standards, the carbon emissions of thermal power units and key emission enterprises are:

[0061] E carb p =Q p ×B×f

[0062] E carb b =Q b ×E f

[0063] E carb p is the carbon emission of thermal power units, Q p is the power generation of the thermal power unit, B is the power supply reference value of the unit; f is the correction coefficient;

[0064] E carb b is the carbon emissions of key emission enterprises, Q b E is the non-green electricity purchase amount, f Average emissions from the power grid

[0065] Carbon certificate market collaborative mutual recognition conversion submodule 23: Another trading target of the emission rights market in the carbon market is CCER. CCER can offset carbon emission quotas in the carbon market. One CCER is equal to 1 ton of carbon emissions. In order to prevent repeated calculations in the process of producing green electricity for renewable energy projects, renewable energy power generators can use the green certificates they have obtained to correspond to the CCER calculation. That is, the more green electricity you have, the corresponding CCER carbon emission rights can be offset.

[0066] Q CCER =Q ge *E f

[0067] Q CCERIndicates the amount of CCER that renewable energy projects can obtain, E f represents the average emission factor of the power grid.

[0068] Submodule 24 of unified green environmental attribute value of electricity-certificate-carbon: After completing the conversion of different market transaction targets, electricity users or renewable energy enterprises can obtain green environmental attributes through green electricity trading and green certificate trading, while thermal power enterprises and carbon emission enterprises purchase green environmental attributes through the carbon market to meet the requirements of carbon quota. Therefore, the green environmental attribute value of a CCER can be defined as m, and the green attribute value of a green certificate is m*E. f ; Similarly, the green attribute value of the unit green electricity is The submodule includes a green environment attribute value adding unit 241 , a green environment attribute value consuming unit 242 and a green environment attribute value final acquiring unit 243 .

[0069] Therefore, the green environment attribute value obtained by a transaction subject through the green environment attribute value adding unit 241 can be defined as:

[0070]

[0071] represents the added green environment attribute value of transaction subject i, They are respectively the number of CCERs, the number of green electricity, and the number of green certificates owned by trading entity i.

[0072] The green environmental attribute value consumed by a trading subject due to carbon emissions and the sale of green certificates and green electricity can be defined as:

[0073]

[0074] Indicates the green environment attribute value consumed by transaction subject i; They are respectively the number of green certificates and CCERs sold by trading entity i.

[0075] Therefore, the green attribute that the market user i can finally obtain through market transactions in the electricity-certificate-carbon collaborative market through the green environmental attribute value final acquisition unit 243 is:

[0076]

[0077] For enterprises that have emission quota needs, they only need to have certain green environmental attribute values ​​in the collaborative trading market to meet the emission assessment requirements.

[0078] By establishing the above-mentioned unified trading mechanism, green environmental attribute values ​​can be recognized by the electricity market, carbon market and green certificate market, breaking down the direct trading barriers in various markets and improving the degree of mutual recognition between trading objects.

[0079] IOTA transaction subsystem 3: After completing the unified green environmental attribute trading system, each trading entity can trade through the IOTA (Internet of Things Application) model. The green environmental attribute value owned by each user can be converted into tokens of the IOTA transaction model for trading. The newly added green electricity trading volume, green certificate quantity, carbon emission demand, and CCER quantity of market entities will be regularly converted into green environmental attribute values ​​and traded between market entities in the IOTA model. At the same time, the green environmental attribute values ​​of the entities that need to be subject to carbon emission assessment in the IOTA transaction account will also be regularly tested. This subsystem implements the IOTA transaction process through various modules, including:

[0080] Preparation phase module 31: The transaction parties need to prepare their own IOTA accounts. IOTA accounts can be created through official applications such as Trinity.

[0081] Transaction initiation module 32: User A intends to sell some IOTA tokens to User B. User A enters User B's account address and transaction amount in his account and then initiates the transaction.

[0082] Proof of Work Module 33: To prevent invalid transactions and network attacks, IOTA requires each transaction initiator to perform a certain amount of Proof of Work (PoW). User A's account software automatically performs this process. The PoW process involves some computational work to ensure the security of the network and prevent spam attacks.

[0083] Other transaction confirmation modules 34: In the IOTA network, each new transaction must confirm at least two previous transactions. This is achieved by linking the new transaction with the previous two transactions. User A's account software automatically selects two unconfirmed transactions and includes them in the new transaction for confirmation.

[0084] Transaction Broadcast Module 35: After user A completes the PoW proof and confirms the two previous transactions, user A's transaction will be broadcast to the IOTA network. The transaction is passed to multiple other nodes and waits for confirmation from other nodes.

[0085] Network Confirmation Module 36: Other nodes in the IOTA network automatically verify User A's transaction. Network nodes verify and confirm transactions by checking transaction structure, verifying PoW, confirming previous transactions, and checking balances. If the transaction is considered valid, other nodes will confirm it. Over time, more and more nodes will confirm the transaction, making it more stable and tamper-proof.

[0086] Confirmation completion module 37: Once the transaction is confirmed by enough nodes and reaches the confirmation threshold, the transaction is considered confirmed. Both user A and user B can view the status of the transaction through their respective wallets.

[0087] Receive Transaction Module 38: When the transaction reaches the network’s confirmation threshold, User B’s account will show the received IOTA tokens.

[0088] Transaction Record Retention Module 39: The details of each transaction will be permanently recorded in the IOTA Tangle, which cannot be tampered with or deleted. All transactions are public and can be viewed by anyone, but the user's identity is anonymous.

[0089] The IOTA process ensures that transactions are secure, transparent, and immutable, while eliminating middlemen and transaction fees.

[0090] The monitoring module 4 detects the green environmental attribute value in each user's IOTA account in real time, feeds it back to the monitoring system, and issues assessment reminders to enterprises with carbon emission quota requirements.

[0091] In summary, by establishing mutual recognition algorithms and trading systems between green electricity, green certificates, and carbon trading markets, mutual recognition transactions between different markets can be achieved. At the same time, a decentralized confidential trading method is realized based on IOTA transaction technology, which ensures that green environmental attributes will not be repeatedly counted, and achieves transparency and security in the collaborative trading process.

[0093] This embodiment provides an electricity-certificate-carbon collaborative trading method based on IOTA technology. Figure 2 As shown, the method comprises the following steps:

[0095] Through the mutual recognition conversion method between different markets, the information of each market is uniformly converted into green environmental attribute values;
