Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to a green certificate and carbon right combined transaction platform for cross-chain transaction.
Background
With the development of renewable energy, it is an important subject to enhance the ability of a power grid to consume intermittent renewable energy power generation represented by wind power generation and photovoltaic power generation. In order to solve the problems of low utilization efficiency and poor market competitiveness of the conventional renewable energy power generation and encourage environment-friendly renewable energy power generation, a concept of tradeable green license and carbon emission rights is internationally provided and applied in some countries.

The block chain technology is used as a decentralized, transparent and contract execution automation database technology with traceability, and has the core advantage that mutual trust among different main bodies can be guaranteed, so that the cost of maintaining or remodeling trust is greatly reduced. Each node in the block chain network has the same authority, and the normal operation of the whole data system cannot be influenced by the fault abnormality of any node. The information recorded on the chain is subjected to redundant backup at a plurality of nodes, and the plurality of nodes are required to be commonly authenticated when the data information is updated. The information recorded on the chain is permanently stored, and the complete transmission path of the information recorded on the chain is convenient to trace. All the above steps enable the data storage of the block chain to have higher robustness and reliability. An intelligent contract is a computer protocol deployed in a blockchain that forms, validates, or executes contracts in code without the involvement of a third party. The method ensures that the block chain can efficiently execute various script algorithms without the supervision of a third party, and adapts to the logic and the requirements of various application scenes. The integration of the intelligent contract and the block chain technology increases the flexibility of transaction, changes the sequential execution mode of the traditional transaction system, and is more suitable for the actual complex transaction application scene.
The research in the prior art mainly focuses on the benefits and the influences brought by the implementation scheme of renewable energy quota system and green certificate trading, and the research on the quota system and green certificate market at the detailed level of a specific trading method still needs to be further mined.
Therefore, a combined transaction system of green certificates and carbon rights for cross-chain transaction is provided.

The monitoring department examines green electricity on the network calculated by the renewable energy power generation enterprises according to the intelligent electric meter and obtains green certificates with corresponding quantity, the actual carbon emission of each renewable energy power generation enterprise is also obtained according to the intelligent electric meter, and each renewable energy power generation enterprise participates in broadcasting the green certificates, the carbon right price and the demand quantity to the network according to the self demand.
The working principle is as follows:
and after the enterprises containing renewable energy power generation pass qualification examination, converting the consumed renewable energy power generation amount into green certificate amount, reporting the green certificate amount to an administrative supervision organization for examination, writing the green certificate amount into an intelligent contract, and issuing a green certificate after examination. In addition, the monitoring authority needs to check the green license quota amount and the carbon right quota amount of each participating enterprise, wherein the enterprise with insufficient quota consumption in the green power enterprise converts the part smaller than the quota amount into the green license amount and the carbon right amount of the enterprise with the carbon quota, and writes the green license amount and the carbon right amount into a contract. And the green certificate transaction block chain and the carbon right transaction block chain disclose the information Hash of each supplier and demander on the corresponding transaction relay chain. And (4) settling the number of green certificates and carbon rights of each participating enterprise in the period, wherein the green certificates exceeding the quota part can offset the carbon rights exceeding the quota part. The accounting process is completed by the relay chain.
