Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment of the method comprises the following steps:
referring to fig. 1, fig. 1 is a flowchart of a method for managing renewable energy provided herein, which may include the following steps.
Step 101: acquiring demand information and supply information; wherein the demand information includes a demand amount of the renewable energy power by the demand user, and the supply information includes a supply amount of the renewable energy power by the supply user.
In the process of renewable energy power trading, a demand user distributes the demand amount of renewable energy power through demand information, and a supply user distributes the supply amount of renewable energy power through supply information. The demand user and the release user can directly release information on the block chain through nodes on the block chain or release information through an application program.
The demand information includes one or more of demand amount, demand value, transaction mode, and settlement method of the renewable energy power of the demand user. The supply information includes one or more of a supply amount of renewable energy power that can be supplied to the user, a supply value transaction mode, and a settlement manner.
Step 102: and obtaining the matching degree of the demand information and the supply information through an intelligent contract.
The block chain is provided with a large amount of demand information and supply information, and the demand information of demand users and the supply information of supply users can be matched, so that the transaction information suitable for renewable energy power of the users can be reduced, the matching time of the demand users and the supply users can be shortened, and the execution speed of the transaction can be further improved.
Specifically, the matching degree of the demand information and the supply information may be obtained by an intelligent contract.
In this step, the matching degree between the demand information and the supply information obtained by the smart contract will be described in detail later.
Step 103: when the matching degree is larger than or equal to a preset threshold value, acquiring an accounting node; the accounting node is a node required for completing renewable energy power transaction, and the renewable energy transaction is a transaction between the demand user and the supply user, the matching degree of which is greater than a preset threshold value.
The preset threshold may be set as needed, and the specific value of the preset threshold is not limited in this embodiment.
Due to the diversity of user requirements, a long matching time is required to wait for the required information to be completely matched with the supply information. By setting the preset threshold, the requirement information and the supply information do not need to be waited for to be completely matched, but the information can be considered to be successfully matched when the matching degree of the requirement information and the supply information reaches the preset threshold, so that the matching time of the requirement user and the supply user can be shortened, and the execution speed of the transaction is further improved.
When the matching degree of the demand information and the supply information is larger than a preset threshold value, acquiring an accounting node for completing renewable energy power transaction corresponding to the demand information and the supply information, wherein the accounting node at least comprises a demand user for issuing the demand information and a supply user for issuing the supply information.
Step 104: broadcasting the renewable energy power transaction to the billing node.
Continuing with the above example, after acquiring the billing node required for the renewable energy power transaction between the demand subscriber B and the supply subscriber C, the renewable energy power transaction is broadcasted to the acquired billing node.
In one possible embodiment, n accounting nodes required to complete the renewable energy power transaction may be acquired, and then the renewable energy power transaction is broadcast to the m accounting nodes. Wherein m is greater than or equal to n, and m is less than the number of accounting nodes in the block chain. In this embodiment, the renewable energy power transaction that is successfully matched is not broadcasted to all the accounting nodes in the blockchain, but the renewable energy power transaction is broadcasted to the accounting nodes within the specified range. The accounting nodes of the designated range at least comprise accounting nodes necessary for completing the renewable energy power transaction, and the number of the accounting nodes of the designated range is less than that of the accounting nodes on the block chain.
The accounting nodes in the designated range can be intelligently increased by adopting a random number mode, static node selection can be changed into dynamic nodes, and the nodes are selectively increased according to needs, so that the safety can be improved on the premise of not sacrificing the performance. The number of m is not particularly limited in this embodiment, and the time for achieving consensus among the accounting nodes can be shortened by reducing the number of accounting nodes that need to achieve consensus, so as to improve the transaction speed of renewable energy power.
Step 105: and when the accounting node is successfully verified through a consensus mechanism, settling the renewable energy power transaction.
In this embodiment, the settlement models of the demand user and the supply user are pre-stored in the blockchain by an intelligent contract formula, and when the accounting node is successfully verified by the consensus mechanism, the settlement of the renewable energy power transaction is automatically executed.
After the renewable energy power transaction is settled, data generated by the renewable energy power transaction, such as identity information of a demand user, identity information of a supply user, transaction amount, transaction price and the like, are automatically stored in the block chain network, so that the method is not only used for the renewable energy consumption statistics, but also can provide data support for subsequent consumption allocation.
An implementation manner of "obtaining the matching degree between the demand information and the supply information by the smart contract" in S102 is specifically described below. S102 may specifically include: obtaining a characteristic value of the demand user according to the demand quantity and the demand value, and obtaining a characteristic value of the supply user according to the supply quantity and the supply value; and obtaining the matching degree of the demand information and the supply information according to the characteristic value of the demand user and the characteristic value of the supply user.
In one embodiment of the application, in the renewable energy power consumption process, the demand user and the supply user adopt intelligent transaction matching based on the intelligent contract, and the matching execution of the intelligent contract is completed by defining a transaction function in the intelligent contract. The transaction function is described below.
With S ═ S1，S2，...，SnDenotes a set of offered users, where SnFor the nth one of the subscribers S. For the same reason, B ═ B1，B2，...，BmDenotes a set of demand users, where BmThe mth user among the demand users B.
Obtaining a characteristic value of the demand user according to the demand amount and the demand value, and calculating by adopting the following formula:
Figure BDA0002719848540000091
in the renewable energy power transaction, i is a positive integer less than or equal to n, and M isiThe characteristic value of the ith demand user is the product of the completion amount between the demand user and the supply user and the interval of the corresponding demand value in the current transaction, BminFor the lowest of the demand values of n said demanding users, BmaxFor the highest of the demand values of n said demanding users, SminFor the lowest of n of said offered user values, SiSupply value, Q, for the ith said supply useriIs the completion amount in the demand amount in the current renewable energy transaction.
The characteristic value of the supply user is obtained according to the supply amount and the supply value, and can be calculated by adopting the following formula:
Figure BDA0002719848540000092
in the renewable energy power transaction, j is a positive integer less than or equal to n, and M isjThe j-th characteristic value of the supply user is the product of the completion amount between the demand user and the supply user in the transaction and the interval of the corresponding supply value in the transaction, BjThe requirement value of the jth demanding user.
After the first matching is completed, whether the completion quantity in the demand quantity is equal to the demand quantity is judged, if yes, the next matching is not needed, and if not, the next matching is needed to be performed in the mode until the completion quantity in the demand quantity is larger than or equal to the demand quantity. Because the demand value and the supply value of the renewable energy have large fluctuation, in order to ensure that the demand user and the supply user can be in a bearable range, the fluctuation of the demand value and the supply value in each time needs to be monitored, the completion amount of each renewable energy transaction also needs to be monitored, and the demands of the demand user and the supply user can be met after multiple matching.
Obtaining the matching degree between the demand information and the supply information according to the characteristic value of the demand user and the characteristic value of the supply user, and calculating by adopting the following formula:
P＝(Mi-Mj)2
wherein P is a matching degree of the demand information and the supply information.
The matching degree characterizes the transaction matching success rate of the demand user and the supply user, the smaller the P value is, the better the matching between the two parties is, and the larger the transaction probability is.
In one possible implementation, the sub-chain in which each accounting node is located stores data generated by renewable energy power transactions at the same time. Specifically, nodes in the main chain are grouped, each accounting node is in a different group, information of the sub chain where the accounting node is located is maintained, and different data are processed independently and parallelly, so that multiple groups of data are stored simultaneously, and further the transaction throughput of the sub chain where each accounting node is located far exceeds the throughput of a single main chain. Each accounting node only needs to be responsible for the data of the sub-chain where the accounting node is located, and state data of the whole block chain network is not stored, so that the workload of verifying a single transaction is reduced, the transaction speed is improved, and meanwhile, the cost is reduced.
In one possible implementation manner, the information of the state variables of the contracts in the blockchain can be imported into the relational database while the blockchain is in normal operation, so that the contract state is visualized and can be monitored. The data in the relational database always keeps final consistency with the data submitted to the block chain, the penetrating data query and the dynamic upgrade of the contract are realized, and the contract flexibility and the contract execution efficiency are improved at the same time.
In one possible implementation, the demand user and/or the supply user may be nodes outside the blockchain, and the renewable energy power transaction on the blockchain is implemented by using a blockchain application and the like.
The embodiment provides a management method of renewable energy power, which is applied to a block chain. Firstly, acquiring demand information and supply information; wherein the demand information includes a demand amount of the renewable energy power by a demand user, and the supply information includes a supply amount of the renewable energy power by a supply user; secondly, obtaining the matching degree of the demand information and the supply information through an intelligent contract; thirdly, when the matching degree is larger than or equal to a preset threshold value, acquiring an accounting node; the accounting node is a node required for completing renewable energy power transaction, and the renewable energy transaction is a transaction between the demand user and the supply user, the matching degree of which is greater than a preset threshold value; then broadcasting the renewable energy power transaction to the billing node; and finally, when the accounting node is successfully verified through a consensus mechanism, settling the renewable energy power transaction.
According to the management method of the renewable energy power, the demand information of the demand user and the supply information of the supply user are automatically matched through the intelligent contract, the renewable energy power transaction information meeting the conditions is automatically screened, the intelligent contract transaction without human interference is realized, the accuracy and the transparency of the renewable energy power transaction are improved, the user is prevented from searching for the appropriate renewable energy power transaction information from a plurality of information, and therefore the matching time between the demand user and the supply user is shortened; when the matching degree of the demand information and the supply information is higher than a preset threshold value, the demand user and the supply user are considered to be successfully matched, namely, the judgment of a subsequent consensus mechanism can be carried out without waiting for an execution result that all information is matched by an intelligent contract, the consensus mechanism does not depend on the execution result of the intelligent contract, namely, the contract execution and the system consensus are isolated, so that the execution speed of the transaction is improved; when the consensus mechanism is realized, all nodes on the block chain do not need to be verified, and only the accounting nodes required by the transaction are verified, so that the execution speed of the transaction is improved, and the high concurrency requirement of the renewable energy power transaction is met.
The second method embodiment:
in order to make the technical solution provided by the embodiment of the present invention clearer, the following describes the management method of renewable energy power provided by the embodiment of the present invention with an example in combination with fig. 2.
Due to large distribution difference of energy regions, the renewable energy sources have complex transaction flow, difficult transaction matching in a limited range and more cross-region transaction matching links. Thus, the execution speed of the renewable energy transaction can be increased by dividing the renewable energy power transaction into regions.
Step 201: and acquiring the demand information and the supply information.
Step 202: and obtaining the matching degree of the demand information and the supply information through an intelligent contract.
The regional levels at which renewable energy electricity exchanges are located may include city level, trans-provincial level, headquarters level. When the regional level of the renewable energy power trading place is the city level, the supply quantity of the supply users or the demand quantity of the demand users cannot be met through multiple times of trading matching, the regional level of the renewable energy power trading place can be expanded to the provincial-crossing level for trading matching, multiple times of trading matching are performed, and the regional level of the renewable energy power trading place can be expanded to the headquarter level for trading matching until the demand quantity of the demand users is met when the supply quantity of the supply users or the demand quantity of the demand users cannot be met.
Step 203: when the matching degree is greater than or equal to a preset threshold value, judging the regional level of the renewable energy power exchange; wherein the regional levels may include a city level, a trans-provincial level, and a headquarter level.
It is understood that the renewable energy power transaction may be divided not only according to the city level, the provincial level, and the headquarter level, but also in other manners, such as a district level, a transnational level, and the like, and the regional division level is not limited in the embodiment of the present application. Step 204: and obtaining accounting nodes required by the renewable energy power transaction according to the regional level.
