In addition, the communication unit 11 allows the information acquisition module 10 to exchange information with another power measuring device (solar inverter, meter) in addition to the user terminal 20 and the service server 100 or a service server ( 100) and another server (a third party server 300, an additional server such as the ESS 400) can also be exchanged with information.

The storage unit 12 stores information on power generated or generated by the user, information on power consumed by the user, and information generated through information exchange between the communication unit 11 and the user terminal 20 and the service server 100. It is a component that stores all power related information such as information.

On the other hand, since the storage unit 12 has a lot of data storage space to store all the information on the generated and consumed power in real time, and executing the task of storing the power information too frequently causes unnecessary waste of resources. As follows, the user can store information on power by dividing it into preset time units (for example, every 15 minutes).

The calculation unit 13 generally performs a role of calculating and processing information transmitted to or received from the communication unit 11, and representatively, information on power generated or generated by a user is exchanged with the service server 100. When the power information is blocked, it serves to form a block chain between the information acquisition module 10 and the service server 100, or received from another power measuring device such as a solar inverter or meter. It plays a role of calculating and processing information into information that the information acquisition module 10 can store and analyze.

The control unit 14 is a component in charge of central processing of the information acquisition module 10, and the control unit 14 is a controller, microcontroller, microprocessor, microcomputer, etc. can also be called In addition, the central processing unit may be implemented by hardware, firmware, software, or a combination thereof.

The control unit 14 serves to control the operation of the above-mentioned components or the interface 15 to be described below.

The interface unit 15 is a component that provides the user with information developed or consumed as it is in real time obtained by the user or analyzes the acquired information and provides the analyzed information to the user, and to perform this role, the interface unit ( 15) may include a message queue interface 15b, an Open ADR interface 15b, a third party interface 15a, a SEP interface 15d, and an OBIX interface 15e.

The message queue interface 15b is an interface using a message queue method that provides users with input values stored and outputted in real time through messaging, that is, information developed or consumed by users in real time. It is an interface that stores and provides the information to the user through messaging.

The Open ADR interface 15b is an abbreviation of the Open Automated Demand Response interface. In simple terms, it is an interface that represents the user's developed or consumed information as a signal and provides it to the user. Further, the Open ADR interface 15b utilizes these signals to It is an interface that proposes a method for optimizing power generation or consumption or an efficient generation or consumption method.

The third party interface 15a optimizes the information provided by the third party server 300 described above, accepts it, and compares it with the power information obtained from the information acquisition module 10 to analyze the market price of power to the user and efficiently use power. It is an interface that suggests a way to purchase .

The SEP interface 15d is an abbreviation of the Smart energy profile interface, and not only serves to control smart energy-related data and related devices (solar inverter, meter), but also analyzes the power information acquired by the information acquisition module 10. It is an interface that provides the analyzed information to the user.

OBIX interface 15e is an abbreviation of Open Building Information Exchange interface, and is a web-based building management system. Like the interfaces described above, the power information obtained from the information acquisition module 10 is analyzed and the analyzed information is provided to the user is an interface that

On the other hand, FIG. 3 shows specific components of the information acquisition module 10 through a schematic diagram. If the information acquisition module 10 is actually implemented, more components as shown in FIG. 3 may be included. For reference, it is understood that Autonerv described in the drawings is an alias for the information acquisition module 10 proposed in the present invention.

For reference, it is understood that the components of the information acquisition module 10 shown in FIGS. 2 and 3 are not limited to the above-mentioned components and the illustrated components, and some components may be added or deleted.

In the above, the information acquisition module 10 of the method of providing the P2P electricity trading platform service of the present invention has been examined in detail.

Next, the components of the service server 100 of the present invention will be described in detail through FIGS. 4 to 5 .

4 is a diagram showing simple components of the service server 100 through a schematic diagram.

The service server 100 is a server that provides various interfaces and transaction matching services so that P2P electricity trading between users can be easily or conveniently performed, and like the information acquisition module 10 described above, it is linked to various servers or devices to provide users Additional services may be provided.

First, looking at the components of the service server 100, the service server 100, like the information acquisition module 10, the communication unit 110, storage unit 120, calculation unit 130, control unit 140 and Although it includes the interface unit 150, it performs a different role from the components of the information acquisition module 10.

First, the communication unit 110 basically performs a role of enabling communication with servers such as the user terminal 20 or the third party server 100 and the ESS 400 so that the user's P2P power transaction is made.

The user terminal 20 of the communication unit 110 receives a user's purchase or sale request, an energy storage request through the ESS 400, and the like, and the third party server 100 exchanges information on power market analysis And, with the ESS (400), exchange of related information is made in order to mediate energy storage between the user and the ESS (400).

Next, the storage unit 120 not only stores overall information related to transactions such as purchase or sales requests received from the user terminal 20, purchase amount, sales volume, transaction matching user information, and transaction result information, but also the service server 100. Information obtained through information exchange with other servers (third party server 100, ESS 400, etc.) associated with may be stored.

Meanwhile, the calculation unit 130 blocks and stores the information stored in the storage unit 120 so that a block chain can be formed, and processes calculations for performing a transaction matching algorithm to be described later.

The control unit 140 is a central processing unit of the service server 100 and has the same role performance method and concept as the control unit 14 of the information acquisition module 10, so a description thereof will be omitted.

Next, the interface unit 150 is a user interface or software interface provided to the user so that the user using the service server 100 can easily use the P2P power trading service, including a transaction API interface 150a, an interactive interface ( 150b), a VPP interface 150c and a third party interface 150d.

The transaction API interface 150a is an interface that provides the P2P electricity trading platform as an application to the user so that the user can easily use the P2P electricity trading platform on the user terminal 20. Through the application, the user can access the power trading platform Membership registration, purchase or sale request, sale or purchase amount presentation, purchase or sale modification, etc.

The conversational interface 150b is a user interface that enables conversations between a user and another user and a conversation between a user and a platform manager in the power trading platform, and a user communicates with another user through the conversational interface 150b. By exchanging information, it is possible to easily match the transaction by presenting each other's desired price and conditions, and by enabling the user to exchange conversations with the manager, the user's use of the electricity trading platform causes errors, etc. can be accepted by the manager and processed quickly.

The VPP interface 150c is an abbreviation of a virtual power plant interface and refers to a virtual power plant interface. The VPP interface 150c, which is a virtual power plant interface, serves to observe and control power information generated by distributed energy resources in real time. In other words, it is an interface used to observe and control power information obtained by the information acquisition module 10, which is power information on distributed energy resources, in real time.

Next, since the third party interface 150d has the same role performance method and concept as the third party interface 15c of the information acquisition module 10, description thereof will be omitted.

On the other hand, FIG. 5 shows specific components of the actually implemented service server 100, and includes more detailed configurations compared to FIG. 4, but other configurations are not the main subject of description in this detailed description, so detailed mention is omitted.

In the above, the service server 100 of the method of providing the P2P electricity trading platform service of the present invention has been examined in detail.

Next, a method for providing a P2P electricity trading platform service according to the first embodiment of the present invention will be described.

[제 1 실시 예: 기본 프로세스][First Embodiment: Basic Process]

In the method for providing the P2P electricity trading platform service according to the first embodiment of the present invention, the service server 100 presents a basic process in which the P2P electricity trading platform is provided to the user. Hereinafter, the P2P electricity trading platform is provided to the user. Let's take a closer look at the methods in order.

The method of providing the P2P electricity trading platform service according to the first embodiment of the present invention first starts with the step of storing the acquired power information in blocks at each pre-stored time (S101). Here, the power information may be power generation information or power consumption information, and power-related information obtained from various interface units 15 associated with the information acquisition module 10 (power consumption analysis, power price prediction, etc.) etc. In addition, blocking at each pre-stored time means that the information used in electricity trading is blocked to form a blockchain, which will improve the reliability of users by ensuring that the P2P electricity trading platform secures security based on the blockchain. be a possible factor. On the other hand, if the service server 100 blocks all information in real time to form a block chain, it becomes difficult to search for related information because the blocked information becomes vast, and there is not enough storage space to accommodate the later blocked information. In preparation for a situation in which power transaction cannot be performed, the service server 100 may designate a pre-stored time, that is, a specific time or period, divide information at each designated time, and block the divided information.

After the information acquisition module 10 blocks and stores the acquired power information at each pre-stored time (S101), the service server 100 receives the blocked power information in the next step (S102).

For reference, it is said that the service server 100 receives the blocked power information in step S102, but even if the information acquisition module 10 only acquires power information in step S101 and does not block it, the service server 100 in step S102 receives the information The power information received from the acquisition module 10 may be implemented in blocks for each pre-stored time.

Subsequently, when the service server 100 receives the blocked power information (S102), the service server 100 receives a transaction request from the user terminal 20 (S103). Here, the transaction request may be a sales request of a seller who generates or produces power and sells power, or a purchase request of a buyer who purchases and consumes power. The sales request may include a sales price, a sales quantity, and the like, and the purchase request may include a purchase price, a purchase quantity, and the like, similarly to the sales request. In addition, the transaction request may be a request for a seller and a buyer to mediate each other's transaction if a mutual transaction agreement has already been made between the seller and the buyer before the transaction is matched.

When the service server 100 receives a transaction request from the user terminal 20 (S103), the service server 100 matches transactions based on a pre-stored algorithm and settles the matched transactions (S104). Here, as the pre-stored algorithm, a repeated multiple auction method algorithm and a spline method automatic purchase price determination algorithm may be used, and an algorithm including the intervention of a third party server described above may be used.

When the service server 100 matches transactions based on a pre-stored algorithm and settles the matched transactions (S104), the service server 100 blocks and stores transaction records (S105), according to the first embodiment of the present invention. The method of providing the P2P electricity trading platform service according to is completed.

In the above, the P2P electricity trading platform service providing method according to the first embodiment of the present invention has been reviewed.

When the information acquisition module 10 collects power information in real time (S201), the power information is stored in blocks for each pre-stored time (S202).

When the information acquisition module 10 blocks and stores power information for each pre-stored time (S202), the information acquisition module 10 transmits the blocked power information to the service server 100 (S203).

When the information acquisition module 10 transmits the blocked power information to the service server 100 (S203), the service server 100 receives the blocked power information (S204).

After the service server 100 receives the blocked power information from the information acquisition module 10 (S204), the user terminal 20 requests a sale or purchase request (S205), and the service server 100 ) receives a transaction request from the user terminal 20 and stores it (S206).

When the service server 100 receives a transaction request from the user terminal 20 and stores it (S206), the service server 100 matches and matches transactions based on a pre-stored algorithm (see FIGS. 8 to 12). The settled transaction is settled (S207).

When the service server 100 matches transactions based on a pre-stored algorithm and settles the matched transactions (S207), the service server 100 blocks and stores transaction records (S208), according to the second embodiment of the present invention.

[제 3 실시 예: 기 저장된 알고리즘(반복다중경매방식 알고리즘)][Third Embodiment: Pre-stored Algorithm (Repetitive Multiple Auction Method Algorithm)]

Previously, it has been described that a pre-stored algorithm is used to match P2P electricity trading in the first and second embodiments of the present invention, but the method for providing a P2P power trading platform service according to the third embodiment of the present invention An algorithm for repeated multiple auctions is presented. Here, in the repeated multi-auction method, when a buyer makes a purchase request by making a bid (Bid) for a purchase price and a purchase quantity, and a seller requests a sale by asking (Ask) a sale price and quantity, the service server 100 requests such a transaction. is stored, and sorts the sales requests in the order of the lowest sales price and the purchase requests in the order of the highest purchase price, matches the sales request with the lowest selling price and the purchase request with the highest purchase price, calculates the average price of the two, and calculates the average price. Allows the transaction to proceed, and sets the smaller value between the sales volume and the purchase volume as the settlement amount, settles the transaction as much as the specified settlement amount, and after settlement, if there is any remaining transaction amount among the seller's sales volume or the buyer's purchase volume, another user is replayed for the remaining transaction amount. It is a transaction matching method that matches.

Looking at the repeated multiple auction method of the P2P electricity trading platform service providing method according to the third embodiment of the present invention with reference to FIG. 8, first, the service server 100 receives the sales request from the user terminal 20 It starts at the step of arranging in the order of sale request with the lowest selling price among them (S301).

After the service server 100 sorts the sales requests received from the user terminal 20 in descending order of sales price (S301), the service server 100 determines the purchase price among the purchase requests received from the user terminal 20. Sort in ascending order (S302).

After the service server 100 sorts the purchase requests received from the user terminal 20 in ascending order of purchase price (S302), the service server 100 matches the sales request with the lowest selling price and the purchase request with the highest purchase price. Do (S303).

Next, after the service server 100 matches the sale request with the lowest selling price and the purchase request with the highest purchase price, the service server 100 checks whether there are any remaining sales or purchase requests for another matching (S304). .

The service server 100 checks whether there are remaining sales and purchase requests for another matching (S304), and if there are remaining sales or purchase requests, the service server 100 records the matched transaction (S305). On the other hand, if there are no remaining sales or purchase requests, the repeated multiple auction method ends.

On the other hand, when the service server 100 records the matched transaction, the service server 100 deducts the sales volume and purchase amount by the settlement amount (S305). Here, the settlement amount is the smaller of the sales volume and the purchase volume. If the sales volume the seller wants to sell is "7kWh" and the purchase volume the buyer wants to buy is "3kWh", the settlement amount will be "3kWh", which is the smaller of the sales volume and the purchase volume. , the amount of settlement will be deducted, so that the sales amount will be "4kWh" and the purchase amount will be "0kWh".

Subsequently, when the service server 100 subtracts the sales volume and the purchase amount by the settlement amount (S305), the service server 100 brings the next sales request or purchase request when the sales volume or purchase amount is “0” (S306). .

When the service server 100 obtains the next sales request or purchase request when the sales volume or purchase amount is "0" (S306), the service server 100 returns to step S304 for another matching and returns to the remaining sales request or Check if there is a purchase request.

FIG. 9 is a diagram briefly showing the repeated multiple auction method according to FIG. 8 through a table for easy understanding.

Referring to FIG. 9 , the service server 100 sorts the sales requests of the sellers in the order of lowest selling price among the seller's sales requests as shown in [Table 9-1] for P2P electricity transaction matching, and the buyer as shown in [Table 9-2]. Among the purchase requests of , the purchase requests with the highest purchase price are sorted in order. The service server 100 matches a sale request with the lowest selling price and a purchase request with the highest purchase price based on the sorted transaction requests. Here, referring to the tables of FIG. 9 , the first seller and the first buyer will be matched first. In the matching of the first seller and the first buyer, the matching transaction price will be "90 won", which is the average of the first seller's selling price (100 won) and the second buyer's purchase price (80 won), and the sales volume after matching (7kWh) and purchase volume (3kWh), the smaller value of "3kWh" will be the settlement amount, and 3kWh of settlement volume will be deducted from sales volume and purchase volume, respectively. When the settlement is completed, the first seller's sales volume remains at "4kWh" and the first buyer's purchase volume becomes "0kWh", leaving the first seller's selling price (100 won) and sales volume (4kWh). The transaction is re-matched with the second buyer, who is the buyer's next turn.

In the above, the method of providing the P2P electricity trading platform service according to the third embodiment of the present invention has been reviewed through FIGS. 8 and 9 .

Next, a method for providing a P2P electricity trading platform service according to a fourth embodiment of the present invention will be described.

[제 4 실시 예: 기 저장된 알고리즘(스플라인 가격 곡선 알고리즘)][Example 4: Pre-stored Algorithm (Spline Price Curve Algorithm)]

The method for providing a P2P electricity trading platform service according to the fourth embodiment of the present invention is one of pre-stored algorithms for matching P2P electricity trading, and uses a spline function to calculate an automatic sale/purchase price. It is an algorithm.

First, in order to understand the method of providing the P2P electricity trading platform service according to the fourth embodiment of the present invention, it is necessary to first understand the Spline function.

Simply put, a spline function is a function representing a straight line or curve by obtaining an estimation function for each section of given data, and is mainly used when estimating data values of discontinuous sections.

With this concept of the spline function, the automatic selling/purchasing price calculation algorithm of the P2P power trading platform service according to the fourth embodiment of the present invention will be described.

10 is a diagram illustrating a method of automatically calculating a sale/purchase price through such a spline function.

Referring to FIG. 10 , in a method of automatically calculating a selling/purchasing price through a spline function, first, a seller or a buyer sets a desired selling/purchasing price and a selling/purchasing time and selects a reference point. 10, "P1" is 120 won at 07:00, "P2" is 90 won at 13:00, "P3" is 180 won at 18:00, and "P4" is 80 won at 24:00. would have chosen

In this way, when a seller or a buyer selects a reference point, the service server 100 forms a spline price curve based on the reference point.

The spline price formed in this way can calculate the price of the sales or purchase time period. Specifically, referring to FIG. 10, "P12" is a price determination point for 10:00 o'clock, which is the time zone between "P1" and "P2" selected by the seller or buyer, and this determination point is the price determination point through the spline price curve. It can be seen that this is calculated as "100 won". Similarly, "P23" is the price determination point at 15:00, which is the time between "P2" and "P3" selected by the seller or buyer, and the price of "P23" is determined to be "118 won" through the spline price curve. can know that

Meanwhile, the seller or the buyer may reset the selected reference point through the user interface provided by the service server 100, and an example of such use will be described with reference to FIG. 11 .

FIG. 11 is a diagram showing that a reference point already selected by users is reset by dragging and a new spline price curve is formed based on the reset reference point.

Referring to FIG. 11 , a user may reset a previously selected reference point by dragging through a user interface provided by the service server 100, that is, “P1”, “P2”, and “P3” of FIG. 10 described above. can be reset to "P1'", "P2'", and "P3'" of FIG. 11 through the user's dragging. For reference, "P1" and "P2" only reset the price, and "P3" resets only the time zone, but both the price and time zone can be reset by dragging the user, and the reference point will be maintained as in "P4". may be

In this way, when the user resets the reference point through dragging, the service server 100 creates a new spline price curve according to the reset of the reference point, and induces transactions to be matched through the generated spline price curve.

In the above, the method for providing the P2P electricity trading platform service according to the fourth embodiment of the present invention has been reviewed through FIGS. 10 and 11.

Next, a method for providing a P2P electricity trading platform service according to a fifth embodiment of the present invention will be described.

In a method for providing a P2P electricity trading platform service according to a fifth embodiment of the present invention, after the service server 100 matches transactions between sellers and buyers, third party information is received from the third party server 300 and received. This is an embodiment of a method of settling a transaction based on information from a third party.

Since the method of providing the P2P electricity trading platform service according to the fifth embodiment of the present invention is the same as the method of providing the P2P electricity trading platform service according to the second embodiment of the present invention until step S308, steps S308 and S308 Only the steps after the step will be described.

After the service server 100 matches the transaction based on the pre-stored algorithm (S307), the third party server 300 transmits the third party information to the service server 100 (S308). Here, the third party information is information that predicts and analyzes electricity prices based on climate, temperature, holidays, past transaction history, and power supply and demand conditions.

Subsequently, when the third party server 300 transmits the third party information to the service server 100 (S308), the service server 100 settles the transaction based on the received third party information (S309). Here, step S309 is a service step additionally provided to users using the P2P power trading platform. In general, it is natural for buyers to buy electricity cheaply and sellers to sell electricity expensive somehow. Depending on the purpose, the amount of transaction matching is inevitably reduced. In particular, this phenomenon inevitably becomes more serious depending on specific circumstances. For example, when the power consumption used for heating facilities increases due to a continuous cold wave, there may be sellers who want to sell electricity at a high price using this, and relatively power is low. In spring, fall, and during the day when electricity is not needed, there are bound to be many buyers who want to purchase electricity cheaply. These situations are difficult to satisfy both the seller and the buyer. Accordingly, the service server 100 receives the third party information transmitted by the third party server 300 in association with the third party server 300 that objectively analyzes the market price of electricity according to various situations, and receives the received third party information. It is possible to provide a service that settles the transaction based on the price and presents a price that can satisfy both the buyer and the seller.

Subsequently, when the service server 100 settles the transaction based on the received third-party information (S309), the service server 100 blocks and stores the transaction record while providing P2P power according to the fifth embodiment of the present invention. The method of providing trading platform services is finalized. At this time, although not separately indicated in the drawing, a predetermined fee may be paid to the third party server 300 that provided the third party information. That is, if the parties to the transaction benefit from the transaction by referring to the information provided by the third party server 300, the third party server 300 will naturally receive a fee accordingly. The method of payment may be determined in various ways. For example, if a transaction is made by referring to the above information, a certain percentage of the transaction amount may be paid to the third party server 300, or a set amount for each transaction regardless of the transaction amount. may be paid. Alternatively, only those who wish to use the third party information may pay a predetermined subscription fee or usage fee.

In the above, the method for providing the P2P electricity trading platform service according to the fifth embodiment of the present invention has been looked at.
