Based on the hardware structure, the embodiment of the power transaction method based on the intelligent contract is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a smart contract-based power transaction method according to the present invention.
In a first embodiment, the smart contract-based power transaction method includes the steps of:
step S10, when receiving the electricity utilization request sent by the electricity purchasing party, acquiring an electricity unit price list sent to the blockchain by the electricity selling party.
It should be noted that, the execution body of the embodiment is an intelligent contract-based power transaction device, and may be other devices that can implement the same or similar functions, such as a power transaction controller, which is not limited in this embodiment, and the power transaction controller is taken as an example in this embodiment.
It should be understood that the electricity unit price list refers to a unit price list of each electricity purchase amount interval of the region to which the electricity seller is disposed, and the electricity unit price corresponding to each region is different.
Further, step S10 includes: when receiving an electricity consumption request sent by an electricity purchasing party, acquiring account information of the electricity purchasing party; determining whether the electricity purchasing party is an abnormal user according to the account information; intercepting the electricity utilization request when the electricity purchasing party is determined to be an abnormal user; when the electricity purchasing party is not an abnormal user, determining a login attribution area of an account to which the account information belongs; generating a power unit price list request when the login home zone is a common home zone; and setting the electricity selling party obtained according to the request of the electricity unit price list by the blockchain in the electricity unit price list of the login attribution area.
It can be understood that the account information refers to account information of an electricity purchasing party for sending an electricity consumption request, the account information can be at least one of a mobile phone number, an identity card number and other unique identification information, then whether the electricity purchasing party is an abnormal user or not is determined according to the account information, specifically, whether the account information is located in an abnormal list or not is judged, if yes, the electricity purchasing party is indicated to be the abnormal user, at the moment, the electricity consumption request sent by the electricity purchasing party is intercepted, otherwise, the electricity purchasing party is indicated to not be the abnormal user, then whether a login home area of an account to which the account information belongs is a common home area is continuously determined, if yes, the existence of login risk is indicated, at the moment, an electricity unit price list request is generated according to the electricity consumption request sent by the electricity purchasing party, and if the login home area is not the common home area, the identity information is required to be sent to the electricity purchasing party so as to ensure the safety of the account is indicated.
And step S20, after receiving the confirmation electricity utilization instruction of the electricity purchasing party, generating power transmission and distribution power transaction data according to the confirmation electricity utilization instruction and the power unit price list by calling an intelligent contract.
It is understood that the power consumption confirmation instruction refers to an instruction for confirming power consumption and power consumption, the power consumption confirmation instruction carries at least one of power consumption amount and power unit price confirmation information, and the power transmission and distribution power transaction data refers to data for carrying out power transaction by a power purchasing party and a power selling party, and the power transmission and distribution power transaction data includes the power consumption amount, the power unit price and the power transmission and distribution data.
Further, step S20 includes: after receiving a confirmation electricity utilization instruction of the electricity purchasing party, analyzing the confirmation electricity utilization instruction to obtain electricity purchasing quantity of the electricity purchasing party; determining the unit price of the electric power corresponding to the electricity purchasing quantity according to the unit price list of the electric power; generating exclusive power data of the electricity purchasing party according to the electricity purchasing quantity, the power unit price and the power transmission and distribution data; and packaging the exclusive power data through a target node to generate power transmission and distribution power transaction data.
It should be understood that after receiving the confirmation power consumption instruction, the power consumption amount of the power purchasing party is obtained by analyzing the confirmation power consumption instruction, then the power unit price corresponding to the power consumption amount is queried according to the power unit price list, for example, when the power consumption amount is between [ A1, A2], the power unit price is a, when the power consumption amount is between (A2, A3], the power unit price is b, and because the power data of different power consumption amounts are different, after obtaining the power unit price, the exclusive power data of the power purchasing party is generated by combining the power consumption amount and the power transmission and distribution data, and then the exclusive power data is packaged through the target node, so that the power transmission and distribution power transaction block is obtained and is used as the power transmission and distribution power transaction data.
And step S30, encrypting the power transmission and distribution power transaction data through a random number generation algorithm.
It should be understood that the random number generation algorithm refers to an algorithm that encrypts by means of random number generation, for example, the power transmission and distribution power transaction data is
The random number generated by using the random number generation algorithm is +.>
The encrypted power transmission and distribution power transaction data is expressed as +.>
Compared with other encryption algorithms, the random number generation algorithm has randomness, so that the safety of the encrypted power transmission and distribution power transaction data is higher.
And S40, after receiving confirmation information of the power purchasing party and the power selling party on the encrypted power transmission and distribution power transaction data, determining the risk of the power transaction being attacked.
It can be understood that after the power transmission and distribution power transaction data are encrypted, the encrypted power transmission and distribution power transaction data are respectively sent to the power purchasing party and the power selling party for confirmation, meanwhile, keys are also sent to the power purchasing party and the power selling party, after confirmation information of the power purchasing party and the power selling party on the encrypted power transmission and distribution power transaction data is received, the power purchasing party and the power selling party are indicated to complete confirmation on the encrypted power transmission and distribution power transaction data, and at the moment, the risk of the power transaction being attacked needs to be determined.
And step S50, controlling the current power transaction according to the risk of the power transaction being attacked.
It should be appreciated that after obtaining the risk of the power transaction being attacked, whether to perform the current power transaction is controlled according to the comparison result of the value of the risk of the power transaction being attacked and the preset risk threshold value.
Further, step S50 includes: acquiring node access data of a power distribution network of an electricity seller; determining user nodes and other node sets according to the node access data; determining injection power of the user node accessing to the other node set; when the injection power is a preset power threshold, acquiring a phase angle of the user node and impedance between the user node and each node in the other node set; calculating the power load born by the power distribution network according to the injection power, the phase angle and the impedance; and when the power load is smaller than a preset power load threshold, controlling the current power transaction according to the risk of the power transaction being attacked.
It may be understood that the node access data refers to node data of a power distribution network accessed to an electricity seller, and when determining injection power of a user node accessed to other node sets, whether the injection power is a preset power threshold is determined, if yes, a power load born by the power distribution network is calculated according to the injection power, the phase angle and the impedance, specifically:
wherein ,

Representing the phase angle of the other nodes +.>
Representing impedance->

Further, when the power load is smaller than a preset power load threshold, the controlling the current power transaction according to the risk of the power transaction being attacked includes: when the power load is smaller than a preset power load threshold, judging whether a value corresponding to the risk of the power transaction being attacked is smaller than a preset risk threshold; when the corresponding value of the risk of the power transaction being attacked is smaller than a preset risk threshold, the current power transaction is sent to a power purchasing party; updating node access data of a power distribution network of an electricity seller when receiving successful payment information of the current electric power transaction by the electricity buyer; and stopping the current power transaction when the power load is greater than or equal to a preset power load threshold value and/or the corresponding value of the risk of the power transaction being attacked is greater than or equal to a preset risk threshold value.
It should be understood that when it is determined that the power load is smaller than the preset power load threshold, the power distribution network of the electricity seller may be further connected to the power connector of the electricity purchasing party, at this time, whether the value corresponding to the risk of the power transaction being attacked is smaller than the preset risk threshold is continuously determined, if yes, the risk is indicated to be smaller, the current power transaction is sent to the electricity purchasing party, the electricity purchasing party performs payment of the current power transaction, after the payment is successful, payment success information of the current power transaction is fed back, at this time, node connection data of the power distribution network of the electricity seller is updated, and if any condition is not satisfied, the current power transaction needs to be stopped.
In the embodiment, when receiving an electricity utilization request sent by an electricity purchasing party, an electricity unit price list sent to a blockchain by an electricity selling party is obtained; after receiving a confirmation electricity utilization instruction of the electricity purchasing party, generating power transmission and distribution power transaction data according to the confirmation electricity utilization instruction and the power unit price list by calling an intelligent contract; encrypting the power transmission and distribution power transaction data through a random number generation algorithm; after receiving confirmation information of the power purchasing party and the power selling party on the encrypted power transmission and distribution power transaction data, determining the risk of the power transaction being attacked; controlling the current power transaction according to the risk of the power transaction being attacked; by means of the method, the generated power transmission and distribution power transaction data are encrypted by means of the random number generation algorithm, whether current power transaction is conducted or not is determined according to the risk that power transaction is attacked, point-to-point data interaction between two parties is achieved, and therefore safety of the power transaction can be effectively improved.
In an embodiment, as shown in fig. 3, a second embodiment of the smart contract-based power transaction method according to the present invention is proposed based on the first embodiment, and the step S40 includes:
step S401, after receiving confirmation information of the power transmission and distribution power transaction data encrypted by the power purchasing party and the power selling party, detecting whether an attack node has a behavior of tampering with the power transmission and distribution power transaction data.
Step S402, when detecting that the attack node has a behavior of tampering with the power transmission and distribution power transaction data, determining a block gap between the attack node and the honest chain.
It can be understood that when the behavior of tampering with the power transmission and distribution power transaction data of the attack node is detected, the power transmission and distribution power transaction data is tampered by the attack node, and at the moment, the block gap between the attack node and the honest chain is determined.
Step S403, obtaining the probability that the attack node manufactures the next block and the probability that the honest node manufactures the next block.
Step S404, calculating the probability of eliminating the block gap of the attack node according to the probability of manufacturing the next block by the attack node and the probability of manufacturing the next block by the honest node.
It can be understood that after obtaining the probability that the attack node makes the next block and the probability that the honest node makes the next block, the probability that the attack node eliminates the block gap is calculated, specifically as follows:
wherein ,

Step S405, determining a risk of the power transaction being attacked according to the probability that the attack node eliminates the block gap, the probability that the attack node manufactures the next block, and the probability that the honest node manufactures the next block.
It should be appreciated that after the probability of the attack node eliminating the block gap is obtained, the risk of the power transaction being attacked is determined in combination with the probability of the attack node producing the next block and the probability of the honest node producing the next block.
Further, step S405 includes: calculating an expected growth value of an attack chain corresponding to the attack node according to the probability of the attack node manufacturing the next block and the probability of the honest node manufacturing the next block; counting the number of blocks of the block gap; generating a probability expression for replacing the honest block according to the expected growth value, the number of blocks, the probability of the attack node manufacturing the next block and the probability of the honest node manufacturing the next block; and calculating the risk of the power transaction being attacked according to the block number and the probability expression of the substitution of the honest blocks.
It can be understood that the expected value of increase refers to an expected value of increase of the attack chain, and after obtaining the probability of the attack node manufacturing the next block and the probability of the honest node manufacturing the next block, the expected value of increase of the attack chain is calculated by combining the number of blocks with block gaps, which is specifically as follows:
wherein ,
representing the expected value of the growth of the attack chain, +.>
