Each charging pile 13 can charge and discharge the parked electric vehicles 3, and is used for continuously sensing and writing corresponding charging and discharging information into the distributed account book 15 of the block chain system 1.
Each power measuring device 14 is configured to continuously sense and write a corresponding power information into the distributed account book 15 of the blockchain system 1.
The following describes how the charge demander charges the electric vehicle 3 to be charged held.
First, the charging terminal 41 generates and transmits the charging request to the transaction platform 111 through the input operation of the charging requester. When the server unit 12 receives the charging request generated by the charging terminal 41 from the transaction platform 111, the server unit 12 writes the charging request into the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1. Then, the charging demander can stop the electric vehicle 3 to be charged at the electric vehicle charging station 21 for charging. Then, the server unit 12 obtains a charging schedule of the electric vehicle 3 to be charged through the smart contract 121 in the blockchain system 1, and writes the charging schedule of the electric vehicle 3 to be charged into the distributed account book 15 of the blockchain system 1. Finally, the charging pile 13 electrically connected to the electric vehicle 3 to be charged obtains the charging schedule from the distributed account book 15 of the blockchain system 1, and charges the electric vehicle 3 to be charged according to the charging schedule. It should be noted that, if the charging type of the content to be charged in the charging requirement is a charging/discharging type, the electric vehicle 3 to be charged is charged or discharged according to the charging schedule.
The following describes how the discharging demander sells electric energy using the electric vehicle 3 held to be discharged.
First, the discharge end 42 generates and transmits the electricity selling demand to the trading platform 111 through the input operation of the discharge demander. When the server unit 12 receives the electricity selling demand including the content to be sold, which is generated by the discharging terminal 42, from the transaction platform 111, the server unit 12 writes the content to be sold into the distributed book 15 of the blockchain system 1 through the intelligent contract 121 in the blockchain system 1, and posts the content to be sold to the transaction platform 111 as the content to be sold, and determines whether there is a matching purchase content matching the content to be sold in all the content to be purchased posted in the transaction platform 111 that is not matched for transaction, when the server unit 12 determines that the matching purchase content exists, the server unit 12 generates a first transaction matching result (i.e. a matching result related to the electricity selling of the discharging terminal 42) according to the content to be sold and the matching purchase content through the intelligent contract 121 in the blockchain system 1, writing the first transaction matching result into the distributed account book 15 of the blockchain system 1, and posting the first transaction matching result on the transaction platform 111; when the server unit 12 determines that the paired purchased content does not exist, the server unit 12 may determine whether the paired purchased content exists again after a predetermined time, or the server unit 12 does not act first and then determines whether the paired purchased content exists again after waiting for a new content to be purchased that is not matched for transaction to be posted on the transaction platform 111. After the pairing purchase content is successfully paired, the discharging demander can stop the electric vehicle 3 to be discharged at the electric vehicle charging station 21 for discharging. Then, the server unit 12 obtains a discharging schedule of the electric vehicle 3 to be discharged through the smart contract 121 in the blockchain system 1, and writes the discharging schedule of the electric vehicle 3 to be discharged into the distributed account book 15 of the blockchain system 1. Finally, the charging pile 13 electrically connected to the electric vehicle 3 to be discharged obtains the discharge schedule from the distributed book 15 of the blockchain system 1, and discharges the electric vehicle 3 to be discharged according to the discharge schedule. It should be noted that the content to be sold in the first transaction pairing result includes identification information of the discharging demander corresponding to the discharging demander, and when the charging pile 13 electrically connected to the electric vehicle 3 to be discharged senses the discharging information which is from the electric vehicle 3 to be discharged and which is held by the discharging demander and includes the identification information of the discharging demander, the charging pile 13 writes the discharging information into the distributed account book 15 of the block chain system 1. Then, the server unit 12 obtains the discharge information corresponding to the content to be sold in the first transaction matching result from the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual transaction content corresponding to the content to be sold in the first transaction matching result according to the discharge information, writes the actual transaction content into the distributed book 15 of the blockchain system 1, and posts the actual transaction content to the transaction platform 111. Thereby, the discharging demander selling electric energy can determine whether the electric energy indicated by the content to be sold is actually sold by the verification of the server unit 12.
The following describes how the green electricity charging demander purchases and sells green electricity using the electric vehicle 3 to be charged.
First, the green charging terminal 43 generates and transmits the green power purchase request to the transaction platform 111 through the input operation of the green charging requester. When the server unit 12 receives the green power purchase demand including the content of green power to be purchased from the green power charging terminal 43 from the transaction platform 111, the server unit 12 writes the content of green power to be purchased into the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and posts the content of green power to be purchased to the transaction platform 111 as the content of green power to be purchased, and determines whether there is a matching green power content matching the content of green power to be purchased in all green power contents to be sold that are posted in the transaction platform 111 that are not matched for transaction, when the server unit 12 determines that there is the matching green power content, the server unit 12 generates a second matching result (i.e. a matching result about the green power purchase of green power charging terminal 43) according to the content of green power to be purchased and the matching green power content by the smart contract 121 in the blockchain system 1, writing the second transaction pairing result into the distributed account book 15 of the blockchain system 1, and posting the second transaction pairing result on the transaction platform 111; when the server unit 12 determines that the paired vending content does not exist, the server unit 12 may determine whether the paired vending content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new green tv content to be vended that is not matched for a transaction to be posted on the transaction platform 111, and then determines whether the paired vending content exists again. After the pairing selling green electricity content is successfully paired, the green electricity charging demander can stop the electric vehicle 3 to be charged in the electric vehicle charging station 21 to charge the green electricity. Then, the server unit 12 obtains a charging schedule of the electric vehicle 3 to be charged through the smart contract 121 in the blockchain system 1, and writes the charging schedule of the electric vehicle 3 to be charged into the distributed account book 15 of the blockchain system 1. Finally, the charging pile 13 electrically connected to the electric vehicle 3 to be charged obtains the charging schedule from the distributed account book 15 of the blockchain system 1, and charges the electric vehicle 3 to be charged according to the charging schedule. It should be noted that the content of the green electricity to be purchased in the second transaction matching result includes identification information of the green electricity charging demander corresponding to the green electricity charging demander, and when the charging pile 13 electrically connected to the electric vehicle 3 to be charged senses the charging information which is from the electric vehicle 3 to be charged and which is held by the green electricity charging demander and includes the identification information of the green electricity charging demander, the charging pile 13 writes the charging information into the distributed book 15 of the block chain system 1. Then, the server unit 12 obtains the charging information corresponding to the content of green electricity to be purchased in the second transaction matching result from the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual content of green electricity transaction corresponding to the content of green electricity to be purchased in the second transaction matching result according to the charging information, writes the actual content of green electricity transaction into the distributed book 15 of the blockchain system 1, and posts the actual content of green electricity transaction to the transaction platform 111. Thus, the green charging demander who buys green power can determine whether he or she actually buys the green power indicated by the green power content to be bought by the verification of the server unit 12.
The following explains how the green electricity discharge demander sells the green electricity using the electric vehicle 3 held to be discharged.
First, the green power discharge terminal 44 generates and transmits the green vending request to the transaction platform 111 through the input operation of the green power discharge requester. When the server unit 12 receives the green power vending request including the green power vending content from the green power discharging terminal 44 from the transaction platform 111, the server unit 12 writes the green power vending content into the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and announces the green power vending content to the transaction platform 111 as the green power vending content, and determines whether there is a pairing green power purchasing content matching the green power vending content in all green power purchasing contents announced to the transaction platform 111 and not matching the green power purchasing content, when the server unit 12 determines that there is the pairing green power purchasing content, the server unit 12 generates a third pairing result (i.e. a pairing result related to the green power vending terminal 44) according to the pairing green power vending content and the pairing green power purchasing content through the smart contract 121 in the blockchain system 1, writing the third transaction pairing result into the distributed account book 15 of the blockchain system 1, and posting the third transaction pairing result on the transaction platform 111; when the server unit 12 determines that the paired purchased green tv content does not exist, the server unit 12 may determine whether the paired purchased green tv content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new green tv content to be purchased that is not matched for transaction to be posted on the transaction platform 111, and then determines whether the paired purchased green tv content exists again. After the pairing purchase green power content is successfully paired, the green power discharging demander can stop the electric vehicle 3 to be discharged at the electric vehicle charging station 21 for discharging. Then, the server unit 12 obtains a discharging schedule of the electric vehicle 3 to be discharged through the smart contract 121 in the blockchain system 1, and writes the discharging schedule of the electric vehicle 3 to be discharged into the distributed account book 15 of the blockchain system 1. Finally, the charging pile 13 electrically connected to the electric vehicle 3 to be discharged obtains the discharge schedule from the distributed book 15 of the blockchain system 1, and discharges the electric vehicle 3 to be discharged according to the discharge schedule. It should be noted that the green electricity content to be sold in the third transaction pairing result includes identification information of a green electricity discharging demander corresponding to the green electricity discharging demander, and when the charging pile 13 electrically connected to the electric vehicle 3 to be discharged senses the discharging information which is from the electric vehicle 3 to be discharged and which includes the identification information of the green electricity discharging demander, the charging pile 13 writes the discharging information into the distributed book 15 of the block chain system 1. Then, the server unit 12 obtains the discharge information corresponding to the green phone content to be sold in the third transaction matching result from the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual green phone transaction content corresponding to the green phone content to be sold in the third transaction matching result according to the discharge information, writes the actual green phone transaction content into the distributed book 15 of the blockchain system 1, and posts the actual green phone transaction content to the transaction platform 111. Thus, the green electricity discharge demander selling green electricity can determine whether to sell the green electricity indicated by the green electricity content by the verification of the server unit 12.
The following describes how the operator purchases electric energy.
First, the operation terminal 45 generates and transmits the electricity purchasing requirement to the transaction platform 111 through the input operation of the operator. When the server unit 12 receives the power purchase demand including the content to be purchased from the operation terminal 45 from the transaction platform 111, the server unit 12 writes the content to be purchased into the distributed book 15 of the blockchain system 1 through the intelligent contract 121 in the blockchain system 1, and posts the content to be purchased to the transaction platform 111 as the content to be purchased, and determines whether there is a matching sale content matching the content to be purchased in all the contents to be sold that are posted in the transaction platform 111 and not matching the sale, when the server unit 12 determines that there is the matching sale content, the server unit 12 generates a fourth transaction pairing result (i.e. a pairing result related to the power purchase of the operation terminal 45) according to the content to be purchased and the matching sale content through the intelligent contract 121 in the blockchain system 1, writing the fourth transaction matching result into the distributed account book 15 of the blockchain system 1, and posting the fourth transaction matching result on the transaction platform 111; when the server unit 12 determines that the matching sale content does not exist, the server unit 12 may determine whether the matching sale content exists again after the default time, or the server unit 12 does not act first, waits for a new content to be sold that is not matched for a transaction to be posted on the transaction platform 111, and then determines whether the matching sale content exists again. After the matching selling content is successfully matched, the operator can buy the electric energy. Then, depending on whether the object selling electricity to the operator is the discharging demander holding the electric vehicle 3 to be discharged or other operators of other electric vehicle charging stations 21, there are different electricity selling ways, when the object selling electricity to the operator is the discharging demander holding the electric vehicle 3 to be discharged, the discharging demander stops the electric vehicle 3 held by the discharging demander to be discharged at the electric vehicle charging station 21 to discharge so as to sell electricity to the operator; when the object selling electricity to the operator is other operators, the other operators transmit electric energy to the electric vehicle charging station 21 through the power grid to sell electricity to the operator. It should be noted that, when the object sold to the operator is the discharging demander of the electric vehicle 3 to be discharged, the content to be purchased in the fourth transaction pairing result includes operator identification information corresponding to the operator, and when one of the charging piles 13 of the electric vehicle charging station 21 senses the discharging action of any parked electric vehicle 3, the charging pile 13 writes the discharging information corresponding to the discharging action and including the operator identification information into the distributed account book 15 of the block chain system 1. Then, the server unit 12 obtains the discharge information corresponding to the content to be purchased in the fourth transaction matching result from the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual transaction content corresponding to the content to be purchased in the fourth transaction matching result according to the discharge information, writes the actual transaction content into the distributed book 15 of the blockchain system 1, and posts the actual transaction content to the transaction platform 111. Thus, the operator who buys the electric power can determine whether the electric power indicated by the content to be bought is actually bought by the authentication of the server unit 12. When the object selling electricity to the carrier is other carriers, the paired selling content in the fourth transaction paired result includes a seller identification information corresponding to the seller (i.e., other carriers), when the electric energy measuring device 14 installed at the electric energy generating place of the seller and corresponding to the seller senses the electric energy information, the electric energy measuring device 14 generates an electric energy content corresponding to the seller identification information according to the electric energy information and the seller identification information and writes the electric energy content into the distributed account book 15 of the blockchain system 1, then the server unit 12 obtains the electric energy content corresponding to the paired selling content from the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1 and generates an actual selling content corresponding to the paired selling content in the fourth transaction paired result according to the electric energy content, and writes the content to be purchased in the distributed account book 15 of the blockchain system 1, and announces the actual sale content to the transaction platform 111, and when the electric energy measuring device 14 installed in the building 2 and corresponding to the operator senses the electric energy information, the electric energy measuring device 14 generates another electric energy content corresponding to the operator identification information according to the electric energy information and the operator identification information, and writes the another electric energy content into the distributed account book 15 of the blockchain system 1, the server unit 12 obtains another electric energy content corresponding to the content to be purchased from the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and generates an actual purchase content corresponding to the content to be purchased in the fourth transaction matching result according to the another electric energy content, and writes into the distributed account book 15 of the blockchain system 1 and posts the actual purchase to the transaction platform 111. Therefore, whether the discharging demander selling the electric energy or other operators or the operator buying the electric energy can determine whether the electric energy seller and the electric energy buyer really conduct electric energy buying and selling according to the to-be-purchased content and the matching selling content of the fourth transaction matching result by the verification of the server unit 12.
The following describes how the carrier generates the support request.
First, the operation terminal 45 generates and transmits the support request to the transaction platform 111 through the input operation of the operator. When the server unit 12 receives the support request generated by the operation terminal 45 from the transaction platform 111, the server unit 12 writes the support request into the distributed ledger 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1 and announces the support request to the transaction platform 111, and the discharge terminal 42 generates the electricity selling demand in response to the support request announced to the transaction platform 111. However, in other embodiments, the discharge end 42 can also actively generate the electricity selling demand without prior support request to generate the electricity selling demand in response to the support request.
The following describes how the operator sells electric energy.
First, the operation terminal 45 generates and transmits the other electricity selling requirement to the transaction platform 111 through the input operation of the operator. When the server unit 12 receives the other electricity selling demand including the other content to be sold, which is generated by the operation terminal 45, from the transaction platform 111, the server unit 12 writes the other content to be sold into the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and posts the other content to be sold to the transaction platform 111 as the content to be sold, and determines whether there is another paired purchase content matching the other content to be sold, among all the contents to be purchased posted in the transaction platform 111 that are not matched for transaction, when the server unit 12 determines that the other paired purchase content exists, the server unit 12 generates a fifth transaction pairing result (i.e. a pairing result related to the electricity selling of the operation terminal 45) according to the other content to be sold and the other paired purchase content through the smart contract 121 in the blockchain system 1, writing the transaction result into the distributed account book 15 of the blockchain system 1, and posting the fifth transaction pairing result on the transaction platform 111; when the server unit 12 determines that the other paired purchasing content does not exist, the server unit 12 may determine whether the other paired purchasing content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new to-be-purchased content that is not matched for transaction to be posted on the transaction platform 111, and then determines whether the other paired purchasing content exists again. After the other pairing purchase content is successfully paired, the operation terminal 45 can sell the electric energy. Then, depending on whether the electricity selling object of the operator is the resident of the building 2 or another operator of another electric vehicle charging station 21, there are different electricity selling routes, and when the electricity selling object of the operator is the resident of the building 2, the operator outputs the electric energy to the corresponding resident of the building 2 by using the internal electric wire; when the electricity selling object of the operator is other operators, the operator transmits the electric energy to other operators through the power grid. It should be noted that the content to be sold in the fifth transaction matching result includes the operator identification information corresponding to the operator, when the power measuring device 14 installed in the building 2 and corresponding to the operator senses power information, the power measuring device 14 generates another power content corresponding to the operator identification information according to the power information and the operator identification information and writes the another power content into the distributed account book 15 of the blockchain system 1, the server unit 12 obtains another power content corresponding to the content to be sold in the fifth transaction matching result from the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and generates an actual sold content corresponding to another content to be sold in the fifth transaction matching result according to the another power content and writes the actual sold content into the distributed account book 15 of the blockchain system 1, and announces the actual sale content to the transaction platform 111. Thus, the operator selling electric energy can determine whether the electric energy indicated by the contents to be sold is actually sold by the verification of the server unit 12.
The following explains how the operator purchases green electricity.
First, the operation terminal 45 generates and transmits the other green power purchase request to the transaction platform 111 through the input operation of the operator. When the server unit 12 receives the another green electricity purchasing demand including the another green electricity content to be purchased, which is generated by the operation terminal 45 from the transaction platform 111, the server unit 12 writes the another green electricity content to be purchased into the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and posts the another green electricity content to be purchased to the transaction platform 111 as the green electricity content to be purchased, and determines whether another paired green electricity content matching the another green electricity content to be purchased exists in all green electricity contents to be sold which are not matched to be sold and posted to the transaction platform 111, and when the server unit 12 determines that the another paired green electricity content exists, the server unit 12 generates a sixth paired result (namely, the sixth paired green electricity content is related to the operation terminal) according to the another green electricity content to be purchased and the another paired green electricity content to be sold through the smart contract 121 in the blockchain system 1 45 buying the pairing result of green phone) and writing the pairing result into the distributed account book 15 of the blockchain system 1, and posting the sixth transaction pairing result to the transaction platform 111; when the server unit 12 determines that the other paired vending content does not exist, the server unit 12 may determine whether the other paired vending content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new green tv content to be vended that is not matched for a transaction to be posted on the transaction platform 111, and then determines whether the other paired vending content exists again. After the other pairing selling green electric content is successfully paired, the operator can buy the green electric energy. Then, depending on whether the object selling green electricity to the operator is a green electricity discharge demander or other operators or solar suppliers of other electric vehicle charging stations 21, there are different green electricity selling approaches, and when the object selling green electricity to the operator is the green electricity discharge demander of the electric vehicle 3 to be discharged, the green electricity discharge demander stops the electric vehicle 3 to be discharged held by the green electricity discharge demander in the electric vehicle charging station 21 to perform green electricity discharge so as to sell green electricity to the operator; when the object of selling green electricity to the operator is other operators or solar suppliers, the other operators or solar suppliers transmit green electricity to the electric vehicle charging station 21 through the power grid to sell green electricity to the operator. It should be noted that, when the object selling green electricity to the operator is the green electricity discharging demander of the electric vehicle 3 to be discharged, the other content to purchase green electricity in the sixth transaction pairing result includes the operator identification information corresponding to the operator, and when one of the charging piles 13 of the electric vehicle charging station 21 senses the green electricity discharging behavior of any parked electric vehicle 3, the charging pile 13 writes the discharging information corresponding to the green electricity discharging behavior and including the operator identification information into the distributed book 15 of the block chain system 1. Then, the server unit 12 obtains the discharging information corresponding to the other green electricity content to be purchased in the sixth transaction matching result from the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual green electricity transaction content corresponding to the other green electricity content to be purchased in the sixth transaction matching result according to the discharging information, writes the actual green electricity transaction content into the distributed book 15 of the blockchain system 1, and announces the actual green electricity transaction content to the transaction platform 111. Thus, the operator who buys the green power can determine whether the operator actually buys the green power indicated by the content of the green power he wants to buy by the authentication of the server unit 12. When the object selling green power to the carrier is other carrier or solar supplier, the other paired sold green power content in the sixth transaction paired result includes a green power vendor identification information corresponding to the green power vendor (i.e., other carrier or solar supplier), when the power measuring device 14 installed at the green power generation site of the green power vendor and corresponding to the green power vendor senses the power information, the power measuring device 14 generates a further power content corresponding to the green power vendor identification information according to the power information and the green power vendor identification information and writes the further power content into the distributed book 15 of the blockchain system 1, and then the server unit 12 obtains a further power content corresponding to the other paired sold green power content in the sixth transaction paired result from the distributed book 15 of the blockchain system 1 through the intelligent contract 121 in the blockchain system 1, and generating an actual vending green tv content corresponding to another green tv vending content in the sixth transaction pairing result according to the another electric energy content, writing the actual vending green tv content into the distributed account book 15 of the blockchain system 1, and posting the actual vending green tv content on the transaction platform 111, wherein the another green tv content to be purchased in the sixth transaction pairing result includes the operator identification information corresponding to the operator, when the electric energy measuring device 14 installed in the building 2 and corresponding to the operator senses the electric energy information, the electric energy measuring device 14 generates another electric energy content corresponding to the operator identification information according to the electric energy information and the operator identification information and writes the another electric energy content into the distributed account book 15 of the blockchain system 1, and the server unit 12 obtains another green tv content to be purchased corresponding to the another green tv vending content in the sixth transaction pairing result from the distributed account book 15 of the blockchain system 1 through the intelligent contract 121 in the blockchain system 1 And generates an actual green electricity purchasing content corresponding to the content to be purchased in the sixth transaction matching result according to the another electric energy content, writes the actual green electricity purchasing content into the distributed book 15 of the blockchain system 1, and posts the actual green electricity purchasing content to the transaction platform 111. Therefore, whether the discharging demander selling the green electric energy, other operators or solar energy suppliers or the operator buying the electric energy can determine whether the green electric energy selling party and the green electric energy buying party really buy the green electric energy and sell the green electric energy according to the other green electric content to be bought and the other green electric content to be sold of the sixth transaction pairing result by the verification of the server unit 12.
The following describes how the operator sells green electricity.
First, the operation terminal 45 generates and transmits the other green vending request to the transaction platform 111 through the input operation of the operator. When the server unit 12 receives the another green tv sale request including another green tv content to be sold, which is generated by the operation end 45, from the transaction platform 111, the server unit 12 writes the another green tv content to be sold into the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and announces the another green tv content to be sold to the transaction platform 111 as the green tv content to be sold, and determines whether another paired green tv content matching the another green tv content to be sold exists in all green tv contents to be purchased announced to the transaction platform 111 that are not matched for transaction, and when the server unit 12 determines that the another paired green tv content exists, the server unit 12 generates a seventh pairing result (that is, a result related to the operation end 45) according to the another green tv content to be sold and the another paired green tv content to be purchased through the smart contract 121 in the blockchain system 1 Match result of selling green phone), and write into the distributed account book 15 of the blockchain system 1, and post the seventh transaction match result to the transaction platform 111; when the server unit 12 determines that the other pairing purchase green content does not exist, the server unit 12 may determine again whether the other pairing purchase green content exists after the default time, or the server unit 12 does not act first, waits for a new green content to be purchased that is not matched for transaction to be posted on the transaction platform 111, and then determines again whether the other pairing purchase green content exists. After the other pairing purchase green electricity content is successfully paired, the operation terminal 45 can sell green electricity energy. Then, depending on whether the object for selling green electricity by the operator is the resident of the building 2, other operators of other electric vehicle charging stations 21, or a green electricity charging demander, there are different electricity selling approaches, and when the object for selling green electricity by the operator is the resident of the building 2, the operator outputs green electricity to the corresponding resident of the building 2 by using the internal electric wire; when the operator sells the green electricity, the operator transmits the green electricity to other operators through the power grid; when the object of selling green electricity by the operator is the green electricity charging demander holding the electric vehicle 3 to be charged, the operator charges the electric vehicle 3 to be charged, which is parked in the electric vehicle charging station 21, with green electricity through the charging pile 13 of the electric vehicle charging station 21 to sell green electricity to the green electricity charging demander. It should be noted that, when the carrier sells a green electricity object as a green electricity charging demander of the electric vehicle 3 to be charged, another content to be sold in the seventh transaction pairing result includes the carrier identification information corresponding to the carrier, and when one of the charging piles 13 of the electric vehicle charging station 21 senses a green electricity charging behavior of any parked electric vehicle 3, the charging pile 13 writes the charging information corresponding to the green electricity charging behavior and including the carrier identification information into the distributed account book 15 of the block chain system 1. Then, the server unit 12 obtains the charging information corresponding to the other green phone content to be sold in the seventh transaction matching result from the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual green phone transaction content corresponding to the other green phone content to be sold in the seventh transaction matching result according to the charging information, writes the actual green phone transaction content into the distributed book 15 of the blockchain system 1, and posts the actual green phone transaction content to the transaction platform 111. Thus, the operator selling green electric energy can determine whether the operator actually sells the green electric energy indicated by the green electric content to be sold by the operator through the verification of the server unit 12. When the object of the operator selling green electricity is a resident of the building 2 or other operators, the other green electricity content to be sold in the seventh transaction matching result includes the operator identification information corresponding to the operator, when the power measuring device 14 installed in the building 2 and corresponding to the operator senses power information, the power measuring device 14 generates another power content corresponding to the operator identification information according to the power information and the operator identification information and writes the another power content into the distributed account 15 of the blockchain system 1, the server unit 12 obtains another power content corresponding to the other green electricity content to be sold in the seventh transaction matching result from the distributed account 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1 and generates an actual green electricity content corresponding to the other green electricity content to be sold in the seventh transaction matching result according to the another power content, and writes the actual sale of the green phone content into the distributed account book 15 of the blockchain system 1 and announces the actual sale of the green phone content to the transaction platform 111. Thus, the operator selling green electric energy can determine whether the operator actually sells the green electric energy indicated by the content to be sold through the verification of the server unit 12.
The following describes how the server unit 12 schedules each electric vehicle 3 parked at the electric vehicle charging station 21 and the electric energy storage device 212.
The server unit 12 uses the intelligent contract 121 in the blockchain system 1 to determine the charging rate of the electric vehicle charging station 21 according to a maximum transformer power of the electric vehicle charging station 21, an energy storage information corresponding to the electric energy storage device 212, at least one purchase price for purchasing a unit of electric power, at least one bid price for participating in demand bidding, a payment price for the electric vehicle 3 to be charged for the unit of electric power when the electric vehicle 3 to be charged is discharged by the electric vehicle charging station 21, a penalty price for the electric vehicle charging station 21 when the electric vehicle 3 to be charged is not fully charged with the unit of electric power, a degradation cost consumed by the electric energy storage device 212 for charging or discharging the unit of electric power, a total load 22 electric power of the loads 22, a solar electric power generated by the solar module 211, and revenue of the electric vehicle charging station 21 for participating in the auxiliary service, and the first transaction pairing result, the second transaction pairing result, the third transaction pairing result, the fourth transaction pairing result, the fifth transaction pairing result, the sixth transaction pairing result and the seventh transaction pairing result stored in the distributed book 15 of the blockchain system 1 are used for obtaining a charging and discharging schedule of each parked electric vehicle 3 and the electric energy storage device 212 by utilizing a nonlinear programming.
The following explains how the green electricity purchaser purchases the green electricity.
First, the green electricity purchasing end 46 generates and transmits the further green electricity purchasing requirement to the transaction platform 111 through the input operation of the green electricity purchasing buyer (e.g. other operators or users of the building 2). When the server unit 12 receives the another green cable purchase demand including another green cable content to be purchased, which is generated by the green cable purchase end 46 from the transaction platform 111, the server unit 12 writes the another green cable content to be purchased into the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and posts the another green cable content to be purchased to the transaction platform 111 as a green cable content to be purchased, and determines whether there is another paired sold green cable content matching the another green cable content to be purchased in all green cable contents to be sold which are not matched to a deal posted to the transaction platform 111, and when the server unit 12 determines that there is the another paired sold green cable content, the server unit 12 generates an eighth paired result (namely, a result related to the green cable content to be purchased and the another paired sold green cable content according to the another paired green cable content to be purchased and the another paired sold green cable content in the blockchain system 1 through the smart contract 121 The buyer 46 buys the pairing result of green phone) and writes it into the distributed account book 15 of the blockchain system 1, and announces the eighth transaction pairing result to the transaction platform 111; when the server unit 12 determines that the other pairing vending content does not exist, the server unit 12 may determine whether the other pairing vending content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new green tv content to be vended that is not matched for a transaction to be posted on the transaction platform 111, and then determines whether the other pairing vending content exists again. After the other pairing selling green television content is successfully paired, the green television buyer can purchase green television. It should be noted that, when the power measuring device 14 corresponding to the green electricity buyer senses power information, the power measuring device 14 generates another power content corresponding to the green electricity buyer identification information and writes the another power content into the distributed ledger 15 of the blockchain system 1 according to the power information and the green electricity buyer identification information, the server unit 12 obtains another power content corresponding to another green electricity content to be purchased in the eighth transaction matching result from the distributed ledger 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1 and generates an actual green electricity content corresponding to another green electricity content to be purchased in the eighth transaction matching result according to the another power content, and writes the actual purchase green phone content into the distributed book 15 of the blockchain system 1 and announces the actual purchase green phone content to the transaction platform 111. Thus, the green electricity buyer buying green electricity can determine whether the green electricity indicated by the green electricity buying and selling content is actually bought through the verification of the server unit 12.
The following describes how the green electricity vendor sells green electricity.
First, the green vending terminal 47 generates and transmits the green vending request to the transaction platform 111 through the input operation of the green vendor (e.g., other operators or solar suppliers). When the server unit 12 receives the another green telemarketing request including another green telemarketing content from the green telemarketing end 47 generated by the green telemarketing end 111, the server unit 12 writes the another green telemarketing content into the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, announces the another green telemarketing content to the trading platform 111 as the green telemarketing content to be sold, and determines whether there is another green telemarketing content matched with the another green telemarketing content in all green telemarketing contents not matched for making a deal posted in the trading platform 111, and when the server unit 12 determines that there is the another green telemarketing content to be bought, the server unit 12 generates a ninth pairing result (namely, a result related to the green telemarketing content and the another green telemarketing content according to the another green telemarketing content to be bought and the another green telemarketing content in the blockchain system 1 through the smart contract 121 The selling terminal 47 sells the pairing result of the green phone), and writes the pairing result into the distributed account book 15 of the blockchain system 1, and announces the ninth transaction pairing result to the transaction platform 111; when the server unit 12 determines that the further pairing purchase green content does not exist, the server unit 12 may determine whether the further pairing purchase green content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new green content to be purchased that is not matched for a deal to be posted on the trading platform 111, and then determines whether the further pairing purchase green content exists again. After the other pairing purchase green phone content is successfully paired, the green phone vendor can sell the green phone. It should be noted that, when the electric energy measuring device 14 corresponding to the green electric vendor senses the electric energy information, the electric energy measuring device 14 generates another electric energy content corresponding to the green electric vendor identification information and writes the another electric energy content into the distributed account book 15 of the blockchain system 1 according to the electric energy information and the green electric vendor identification information, and then the server unit 12 obtains another electric energy content corresponding to another green electric content to be sold in the ninth transaction matching result from the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1 and generates an actual sold green electric content corresponding to another green electric content to be sold in the ninth transaction matching result according to the another electric energy content, and writes the actual sale of the green phone content into the distributed account book 15 of the blockchain system 1 and announces the actual sale of the green phone content to the transaction platform 111. Thus, the green electricity vendor selling green electricity can determine whether to sell the green electricity indicated by the green electricity content by the server unit 12.
The following describes how the vendor sells electric energy.
First, the selling terminal 49 generates and transmits the further electricity selling demand to the trading platform 111 through the input operation of the vendor (e.g., other operators). When the server unit 12 receives the further electricity selling demand including the further content to be sold from the selling terminal 49 from the trading platform 111, the server unit 12 writes the further content to be sold into the distributed book 15 of the blockchain system 1 through the intelligent contract 121 in the blockchain system 1, and advertises the further content to be sold to the trading platform 111 as the content to be sold, and determines whether there is further paired purchased content matching the further content to be sold in all the contents to be purchased advertized to the trading platform 111 that are not matched for transaction, when the server unit 12 determines that there is the further paired purchased content, the server unit 12 generates a tenth trading pairing result (i.e. a pairing result related to the electricity selling of the trading terminal 49) according to the further content to be sold and the further paired purchased content through the intelligent contract 121 in the blockchain system 1, writing the transaction result into the distributed account book 15 of the blockchain system 1, and posting the tenth transaction pairing result on the transaction platform 111; when the server unit 12 determines that the other pairing purchase content does not exist, the server unit 12 may determine whether the other pairing purchase content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new to-be-purchased content that is not matched for a deal to be posted on the trading platform 111, and then determines whether the other pairing purchase content exists again. After the matching of the other matching purchase content is successful, the seller can sell the electric energy. It should be noted that, when the electric energy measuring device 14 corresponding to the seller senses the electric energy information, the electric energy measuring device 14 generates another electric energy content corresponding to the seller identification information and writes the another electric energy content into the distributed account book 15 of the blockchain system 1 according to the electric energy information and the seller identification information, and then the server unit 12 obtains another electric energy content corresponding to the another electric energy content from the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and generates an actual sold content corresponding to the another electric energy content in the tenth transaction matching result according to the another electric energy content and writes the actual sold content into the distributed account book 15 of the blockchain system 1, and announces the actual sale content to the transaction platform 111. Thus, the seller selling electric energy can determine whether the electric energy indicated by the contents to be sold is actually sold by the authentication of the server unit 12.
The following describes how the purchaser purchases electric energy.
First, the purchasing end 48 generates and transmits the other electricity purchasing requirement to the transaction platform 111 through the input operation of the purchaser (e.g., other operators or users of the building 2). When the server unit 12 receives the another electricity purchasing requirement including another content to be purchased from the purchasing end 48 from the transaction platform 111, the server unit 12 writes the another content to be purchased into the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, and advertises the another content to be purchased to the transaction platform 111 as the content to be purchased, and determines whether there is another paired sold content matching the another content to be purchased in all the contents to be sold that are advertised in the transaction platform 111 and not matching the transaction, when the server unit 12 determines that there is the another paired sold content, the server unit 12 generates an eleventh transaction pairing result (i.e. a pairing result related to the electricity purchased by the purchasing end 48) according to the another content to be purchased and the another paired sold content through the smart contract 121 in the blockchain system 1, writing the transaction result into the distributed account book 15 of the blockchain system 1, and posting the eleventh transaction pairing result on the transaction platform 111; when the server unit 12 determines that the another paired sold content does not exist, the server unit 12 may determine whether the another paired sold content exists again after the default time elapses, or the server unit 12 does not act first, waits for a new to-be-sold content that is not matched for a transaction to be posted on the transaction platform 111, and then determines whether the another paired sold content exists again. After the another paired selling content is successfully paired, the buyer can purchase the electric energy. It should be noted that, another content to be purchased in the eleventh transaction matching result includes a purchaser identification information corresponding to the purchaser, when the power measuring device 14 corresponding to the purchaser identification information senses power information, the power measuring device 14 generates another power content corresponding to the purchaser identification information according to the power information and the purchaser identification information and writes the another power content into the distributed account book 15 of the blockchain system 1, the server unit 12 obtains another power content corresponding to another content to be purchased in the eleventh transaction matching result from the distributed account book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual purchase content corresponding to another content to be purchased in the eleventh transaction matching result according to the another power content and writes the actual purchase content into the distributed account book 15 of the blockchain system 1, and posts the actual purchase to the trading platform 111. Thereby, the purchaser who buys electric power can determine whether the electric power indicated by the contents to be bought is actually bought by the authentication of the server unit 12.
The following describes how the operator requests the users of the building 2 to save power.
First, the operation terminal 45 generates and transmits the power saving requirement to the transaction platform 111 through the input operation of the operator. When the server unit 12 receives the power saving requirement including the content to be saved generated by the operation end 45 from the transaction platform 111, the server unit 12 writes the content to be saved into the distributed account book 15 of the blockchain system 1 through the intelligent contract 121 in the blockchain system 1, and announces the content to be saved to the transaction platform 111 as the content to be saved. Then, the power saving terminal 51 generates and transmits the power saving compensation demand to the trading platform 111 in response to a to-be-matched one of the to-be-saved contents announced to the trading platform 111 through an input operation of the power saver (i.e., a user of the building 2). When the server unit 12 receives the power saving compensation requirement containing the to-be-compensated content from the transaction platform 111, which is generated by the power saving terminal 51 in response to the to-be-matched power saving content, the server unit 12 determines whether the content to be power-saved to be matched posted in the transaction platform 111 that is not matched for transaction matches for transaction with the content to be compensated through the smart contract 121 in the blockchain system 1, and, as a pair power saving content, when the server unit 12 determines that the pair power saving content is matched, the server unit 12 generates a twelfth transaction matching result (i.e. the matching result related to the power saving of the operation terminal 45) according to the content to be compensated and the matching power saving content through the intelligent contract 121 in the blockchain system 1, and writes the result into the distributed account book 15 of the blockchain system 1, and announces the twelfth transaction matching result to the transaction platform 111. When the server unit 12 determines that the paired power saving content matching the transaction cannot be obtained, the server unit 12 stops the pairing of the content to be compensated. The power-saving person corresponding to the successfully matched content to be compensated can save power in the power-saving time indicated by the content to be compensated. It should be noted that the content to be compensated in the twelfth transaction matching result includes an electricity-saving person identification information corresponding to the electricity-saving person, and when the electric energy measuring device 14 corresponding to the electricity-saving person senses the electric energy information, the electric energy measuring device 14 generates another electric energy content corresponding to the electricity-saving person identification information according to the electric energy information and the electricity-saving person identification information, and writes the another electric energy content into the distributed account book 15 of the block chain system 1. Then, the server unit 12 obtains another power content corresponding to the content to be compensated in the twelfth transaction matching result from the distributed book 15 of the blockchain system 1 through the smart contract 121 in the blockchain system 1, generates an actual power saving content corresponding to the content to be compensated in the twelfth transaction matching result according to the another power content, writes the actual power saving content into the distributed book 15 of the blockchain system 1, and announces the actual power saving content to the transaction platform 111. Thus, the power saver saving power can determine whether the power saving indicated by the contents to be compensated is actually saved by the verification of the server unit 12.
The following describes how the rescuer requests others to support the power.
First, the help-seeking terminal 52 generates and transmits the help-seeking request to the transaction platform 111 through the input operation of the help-seeking person. When the server unit 12 receives the help-seeking request including the content to be help-seeking purchase from the transaction platform 111, the server unit 12 writes the content to be help-seeking purchase into the distributed account book 15 of the blockchain system 1 through the intelligent contract 121 in the blockchain system 1, and announces the content to be help-seeking purchase to the transaction platform 111 as the content to be help-seeking purchase. In this embodiment, the situation that the person seeking help sends the help-seeking request through the help-seeking terminal 52 can be, the person seeking help is driven by an electric vehicle 3, which is held, and the electric power is insufficient during the driving, and thus, the contents of the SOS request to be purchased include the position of the electric vehicle 3 held by the SOS requester, the amount of the electric energy to be purchased, and the price of the electric energy to be purchased, the position of the electric car 3 in the content of the purchase to be rescued posted on the transaction platform 111 may be the GPS coordinates of the electric car 3 held by the rescuer, or, in order to protect the privacy of the rescuer, the position of the electric vehicle 3 in the contents to be SOS and purchased in the SOS request is the GPS coordinate of the electric vehicle 3 held by the SOS, however, the position of the electric car 3 in the content of the purchase to be asked for help announced on the transaction platform 111 is only a position area where the electric car 3 held by the person to be asked for help is located. Then, the rescue terminal 53 responds to a to-be-matched purchasing content to be rescued from the to-be-rescued purchasing contents announced to the trading platform 111 through the input operation of the rescuer, and generates and transmits the rescue demand to the trading platform 111. When the server unit 12 receives the rescue demand including the to-be-rescued purchased content from the transaction platform 111, which is generated by the rescue terminal 53 responding to the to-be-rescued purchased content to be matched, the server unit 12 determines whether the to-be-rescued purchased content which is posted on the transaction platform 111 and is not matched for delivery is matched with the to-be-rescued purchased content as a paired distress purchased content through the intelligent contract 121 in the blockchain system 1, and when the server unit 12 determines that the paired distress purchased content is matched, the server unit 12 generates a thirteenth transaction pairing result (i.e. a pairing result related to the rescue terminal 52 requesting the rescue terminal 53 for power rescue) according to the to-be-rescued purchased content and the paired distress purchased content through the intelligent contract 121 in the blockchain system 1 and writes the thirteenth transaction pairing result into the distributed book 15 of the blockchain system 1, and the thirteenth transaction pairing result is posted to the transaction platform 111. When the server unit 12 determines that the matched paired help-seeking purchase content is not available, the server unit 12 stops the pairing of the to-be-rescued sold content. The rescuer who is successfully matched with the sale content to be rescued can drive the electric car 3 to the position of the electric car 3 indicated by the paired distress purchase content and transmit the electric power to the electric car 3 held by the rescuer by using the electric power transmission device 16 held by the rescuer, it is worth mentioning that the sale content to be rescued in the thirteenth transaction pairing result comprises rescuer identification information corresponding to the rescuer, when the electric power transmission device 16 corresponding to the rescuer senses discharge information, the electric power transmission device 16 generates an electric power transmission content corresponding to the rescuer identification information according to the discharge information and the rescuer identification information and writes the electric power transmission content into the distributed account 15 of the block chain system 1, and then the server unit 12 obtains the electric power corresponding to the sale content to be rescued in the thirteenth transaction pairing result from the distributed account 15 of the block chain system 1 through the intelligent contract 121 in the block chain system 1 The content is transmitted, and an actual rescue sale content corresponding to the to-be-rescued sale content in the thirteenth transaction matching result is generated according to the power transmission content, and is written into the distributed account 15 of the blockchain system 1, and the actual rescue sale content is posted to the transaction platform 111. Thereby, the rescuer who provides electric power rescue can determine whether the electric power indicated by the vending contents to be rescued is provided or not by the verification of the server unit 12. It should be noted that, when the position of the electric car 3 in the content to be rescued and purchased posted on the trading platform 111 is only the position area where the electric car 3 held by the rescuer is located, the server unit 12 further transmits the GPS coordinate of the electric car 3 held by the rescuer to the rescue end 53 of the rescuer corresponding to the successfully matched content to be rescued and sold when the matching content to be rescued and purchased is matched.
In summary, in the blockchain system 1 for electric energy transaction of the present invention, the server unit 12 stores the charging requirement in the distributed account book 15 of the blockchain system 1, and the server unit 12 writes all transaction pairing results into the distributed account book 15 of the blockchain system 1, so as to ensure that each electric energy transaction is safe and transparent, and has anonymity and non-fleeability modification, and in addition, the actual electric energy transaction content can be verified by the electric energy information sensed by the electric energy measuring devices 14 of the buyer and the seller or the charging pile 13, so as to keep track of the transaction status of the electric energy transaction, thereby achieving the purpose of the present invention.
