Description

A method of trading electricity between generations of a building and a power trading device performing the method

The present invention relates to a method for transacting electricity between households in a building and a power trading device for performing the method, and more specifically, to the power produced through an energy generation panel installed in the apartment, block chain coins are exchanged between the generations of the apartment. It relates to the electricity trading method used.

A prosumer is a method in which consumers directly or indirectly participate in electricity transaction. In the case of P2P (Peer to Peer) electricity transaction between individual generations, each generation is a prosumer, use it To this end, individual households constituting a multi-family house such as an apartment install a solar power panel in the living space of each individual household, and self-generate electricity through the installed solar power panel. However, in the case of photovoltaic panels installed in individual households, as they are installed in the residential space of each individual household, the installation scale is small and it is difficult to operate efficiently due to space constraints.

In order to solve this problem, in the prior art, for efficient production and management of the amount of electricity produced for electricity trading, solar panels were not installed for each individual household, and large-scale solar energy was installed in places without spatial restrictions, such as on-ground parking lots and building rooftops. By installing a power generation facility, the efficiency of power generation was increased and management was made easy.

In addition, the community composed of the whole or the unit within the apartment building is utilized so that all households can use the electricity produced by the solar power generation facility. All households belonging to the community can participate in electricity trading to obtain economic benefits with respect to the electricity produced by the solar power generation facility that is used for the common use of the community. However, it is a reality that economic benefits are obtained by being limited to some households according to the amount of electricity used by each household. In other words, in general, the generation that consumes a large amount of electricity will mainly participate in electricity transaction to gain benefits, and the generation that consumes a relatively small amount of electricity will have a low participation rate in electricity transaction.

Therefore, there is a need for a power trading method in which all generations of a community using a common photovoltaic power generation facility participate in power trading and achieve economic benefits through this regardless of the power consumption by household.

The present invention provides a method for all generations of a community to obtain economic benefits through electricity trading by using a block chain coin for electricity produced in a public power generation facility installed in a community such as a community house.

The electricity transaction method according to an embodiment of the present invention includes the steps of setting a block chain coin payable for each household in consideration of the amount of electricity generated through an energy generation panel installed in a building and the number of households in the building; performing a power transaction for the conclusion of a power contract between a power seller and a power buyer according to sales conditions and purchase conditions based on the block chain coins set for each generation; and calculating the block chain coins set for each generation in consideration of the time of settlement according to the power transaction.

In the electricity transaction method according to an embodiment of the present invention, all generations of the community can obtain economic benefits through electricity transaction by using a block chain coin for electricity produced in a public power generation facility installed in a community such as an apartment house. .

1 is a diagram illustrating an overall configuration for performing power transaction between generations of a community in a building according to an embodiment of the present invention.

Referring to FIG. 1 , the power transaction device 101 may induce all households 103 living in the building 102 to participate in power transaction by using a block chain coin for power produced in the community. In detail, in the building 102 , an energy generation panel for generating common electric power may be installed in a place without spatial restrictions, such as a ground parking lot or a building roof. The power trading device 101 may induce each generation of a plurality of households residing in the building to participate in power trading with self-generated power through the energy generation panel.

In more detail, the power transaction device 101 may set a block chain coin payable for each household in consideration of the amount of power generated through the energy generation panel installed in the building and the number of households in the building. In other words, the power trading device 101 can provide block chain coins so that all generations can participate in power trading with respect to the power produced in the community of the building. Each generation of the community can all be paid the same blockchain coin. The power transaction device 101 may determine the same block chain coin according to the number of households in a building using the amount of power actually produced by the energy generation panel based on a certain period of time. The power transaction device 101 may collectively pay the determined block chain coin to all generations of the community.

The present invention can set a block chain coin that can be paid for each household in consideration of the amount of electricity generated and the number of households in the building in order to provide all generations of the community with the right to use the amount of power generated by the energy generation panel fairly.

The generation receiving the block chain coin can participate in electricity transaction as a seller or as a buyer for the power produced through the energy generation panel using the issued coin. In other words, according to the present invention, power according to the usage right given to a household may be sold to another person according to the power usage pattern of each generation, or power according to the usage right given to another person may be purchased.

Through this process, the generation who sold block chain coins can obtain economic benefits according to the amount of block chain coins sold. In general, a basic unit price may be determined at a producer or power trading market at the time of power production. The present invention may set the selling unit price in the process of selling power between generations based on a predetermined basic unit price. Accordingly, the generation that sold block chain coins can obtain economic benefits through the difference between the basic unit price and the unit price sold according to the amount sold.

For example, a generation that sold block chain coins at a point in time when the unit selling price is higher than the basic unit price can benefit, and conversely, a generation that sold block chain coins at a time when the unit selling price is lower than the basic unit price can lose.

The generation that purchases the block chain coin will use the power flowing into the household according to the block chain coin, and thus lower the existing power consumption, thereby lowering the electricity rate applied to the generation. In addition, the generation that does not participate in the electricity transaction can basically benefit from the settlement of the same paid coins, so all generations of the community have the advantage of obtaining economic benefits.

2 is a diagram illustrating the structure of a block chain-based power trading platform according to an embodiment of the present invention.

Referring to FIG. 2 , the present invention can use the user DApp 201 so that all generations belonging to the community can participate in power transaction as prosumers with respect to the power produced in the community. All generations of a community capable of participating in power trading can participate in power trading as a seller 203 or a buyer 204 through the user DApp 201 . In other words, the user DApp 201 can be divided into an administrator 202, a seller 203, and a buyer 204 according to the method of using the block chain coin. The user DApp 201 classified as the manager 202 can monitor power transactions made between generations according to the power produced in the community. The user DApp 201 classified as the seller 203 can sell the block chain coins paid through the power transaction device 205 to others, and the user DApp 201 classified as the buyer 204 is the block of another person. You can buy chain coins.

To this end, the seller 203 may upload a post containing the intention regarding the sale of the block chain coin currently held on the transaction list of the user DApp 201 . Here, the post may include the number of block chain coins desired to be sold, a desired sale price, and the like. The buyer 204 may check the post uploaded by the seller 203 and transmit the purchase intention to the seller 203 who has uploaded a post meeting the conditions of the buyer 204 . Thereafter, the seller 203 and the buyer 204 can complete the transaction by signing a contract for power transaction and exchanging block chain coins.

In addition, the power transaction device 205 can perform the functions of user management, transaction management, contract management, and settlement management for power transactions of all generations of the community, and interlocks data according to the transaction with the block chain platform 206 . can do.

3 is a flowchart illustrating a procedure for performing power transaction between generations of a community according to an embodiment of the present invention.

In step 301, the power transaction device may set a block chain coin payable for each household in consideration of the amount of power generated through the energy generation panel installed in the building and the number of households in the building. The power trading device can collectively pay the determined blockchain coins to all generations of the community.

In step 302, the power trading device may monitor posts uploaded to the user DApp used to participate in power trading, and classify all households into sellers and buyers based on the monitoring result. As an example, the power transaction device may classify a generation that uploaded a post to a user DApp to sell block chain coins paid in batches as sellers, and the remaining generations as temporary buyers. The power trading device can monitor the posts uploaded to the user DApp in real time, and can distinguish between sellers and buyers for all generations.

In step 303, when the division into sellers and buyers is completed for all households, the power transaction device can identify the conditions of sale and purchase described in the posts uploaded to the user DApp. For example, the generation receiving block chain coins is divided into the role of the seller and the role of the buyer, and according to the role, sales and purchase conditions can be registered through postings. The power trading device may identify the registered sales conditions and purchase conditions through the posting.

In step 304, the power transaction device may register the transaction volume that was made in the past using the block chain coins paid to each generation in the community that are different from the sales conditions and purchase conditions registered through the posting. The power trading device may be contracted according to the sales and purchase conditions registered for each household according to the transaction volume.

In step 305, the purchaser can use the power according to the power amount of the contract concluded between generations using the block chain coin.

In step 306, the power transaction device may be settled at the end of the contract period, and the generation that sold the block chain coin through this will obtain economic benefits.

4 is a flowchart illustrating a procedure for setting and setting a block chain coin payable for each generation according to an embodiment of the present invention.

Referring to FIG. 4 , the power transaction device may set the amount of coins to be equally paid for each household by dividing the total amount of power generation by the number of households based on the specifications of the energy generation panel installed in the building. In the present invention, the payment of block chain coins may be made in units of settlement cycles according to power transactions, which may be paid in units of days, weeks, or months. And, after the power transaction device is paid to all generations of the community, it is possible to set the standard unit price of the block chain coin.

Thereafter, the power trading device may calculate the amount of power generation actually produced through the energy generation panel during the contract period, compare it with the amount of power applied at the time the coin is paid, calculate the settlement ratio, and perform the settlement.

For example, in the case of monthly power transaction, if 100 100W class solar panels installed in the community (10kw) are installed and the average daily power generation is calculated for 9 hours, then the total power generation amount of 2700kWh will come out for a month. . This can be expressed as Equation 1 below.

At this time, if the community generation is 30 generations, if 1 coin is set per 1 kWh, 90 coins can be paid to each generation. And, if the unit price per coin is set at 90 won, the generation who did not participate in the transaction can receive 8,100 won (90 coins * 90 won) by applying the standard coin unit price (90 won).

In addition, according to the present invention, in the case of a generation that does not require electricity transaction, even if it does not participate in electricity transaction, a basic economic benefit of 8,100 won is obtained. The unit price of the coin used for power transaction can be set higher than the standard unit price of the coin to induce active power trading. At this time, the actual amount of power generation is flexible due to the influence of weather and the like. In the present invention, the actual amount of power generation is calculated at the time of settlement, and the actual settlement can be made by applying the corresponding ratio.

If the monthly power generation was 2700 kWh and the actual power generation was 2000 kWh, the settlement ratio of 0.74 (2000/2700) can be applied. In this case, in the present invention, the standard of coins applied to settlement may be changed from 1 to 0.74. The settlement ratio calculated at the time of settlement may be calculated by reflecting the amount paid to each household according to the actual amount of power generation.

In the case of households that did not participate in the electricity transaction, the settlement ratio of 0.74 is applied at the time of settlement to actually receive 5,994 won (0.74 * 90 coins * 90 won), and the seller applies the computation ratio to the coins sold according to the settlement ratio can be In the case of a purchaser, the amount of electricity corresponding to the coin value to which the settlement ratio is applied will be used. For example, when 40 coins are purchased at 1 kWh for 1 coin, if the settlement ratio is 0.74, 29.6 kWh (0.74 * 40 coins * 1 kWh) is actually used for power transaction.

5 is a diagram illustrating a procedure for settling a block chain coin according to an embodiment of the present invention.

Referring to FIG. 5 , the coin settlement procedure when generation A and B among all generations of the community participates in electricity trading as sellers and buyers can be described as follows.

Generation A registered 50 coins at a selling price of 100 won as a seller, and Generation B registered 40 coins at a purchase price of 100 won and a contract was concluded. In the case of Generation A, 50 of the 90 coins received are used for sale, and the remaining 40 coins are settled by applying the standard unit price, resulting in a profit of 8,600 won.

Generation B purchases 40 coins and pays 400 won by deducting the selling price from the standard unit price, and a profit of 4,500 won is generated for the remaining 50 coins, resulting in a final profit of 4,900 won as a result of settlement.

In the case of Generation B, if the actual usage per month is 400kWh by receiving and using the electricity corresponding to 40 coins traded, 360kWh of electricity is charged excluding the purchased 40kWh. The current progressive tax applied in Korea is divided into three stages and electricity rates are charged.

As a summer standard, 300kWh or less for section 1, 301~450kWh for step 2, and over 450kWh for step 3 are applied. In the case of households using the threshold of each stage, if the progressive tax section is lowered through this community power transaction, economic benefits can be obtained that can significantly lower the electricity bill.

6 is a diagram illustrating a procedure for settling a block chain coin of a power seller according to an embodiment of the present invention.

In step 601 , the power trading device may pay the power seller a block chain coin. At this time, the block chain coin paid to the power seller may be the same as the block chain coin paid to the power consumer, and here, the block chain coin paid may be a basic coin provided for all generations of the community.

In step 602, the power transaction device may receive a request to register the sale amount and unit price of the block chain coin paid from the power seller, and may register it. The power trading device may induce participation in power trading according to the registered sales amount and unit price.

In step 603, the power trading device may settle the basically identically provided block chain coins of the power seller according to the power transaction. The power trading device can settle the block chain coins by applying the basic unit price to the value obtained by subtracting the sales coins from the basic coins of the power seller.

In step 604, the power trading device may settle the block chain coins sold by the power seller according to the power transaction. The power trading device can settle the block chain coins by multiplying the block chain coins sold by the power seller by the selling unit price.

In step 605, the power transaction device adds the settlement value (basic coin settlement) of the block chain coin settled in step 603 and the settlement value of the block chain coin settled in step 604 (sale coin settlement) to the transaction seller Can perform final settlement for .

7 is a diagram for explaining a procedure for settling a block chain coin of a power purchaser according to an embodiment of the present invention.

In step 701, the power trading device may pay the same block chain coin to the power buyer for all generations of the community.

In step 702, the power transaction device may induce the power purchaser to participate in the power transaction using the received block chain coin, and the power purchaser may purchase the power seller's block chain coin through the power transaction device.

In step 703, the power trading device may settle the block chain coins provided to the power purchaser according to the power transaction. The power transaction device can settle the block chain coin by applying the basic unit price of the block chain coin to the value obtained by subtracting the purchase coin from the block chain coin.

In step 704, the power trading device may settle the block chain coins purchased by the power purchaser according to the power transaction. The power transaction device can calculate block chain coins by multiplying the selling price by subtracting the purchase price based on the block chain coin purchased by the power purchaser.

In step 705, the power transaction device adds the settlement value (existing coin settlement) of the block chain coin settled in step 703, and subtracts the settlement value (purchase coin settlement) of the block chain coin settled in step 704 Thus, the final settlement for the sales buyer can be performed.
