Figure 1 is a diagram showing a method of providing the P2P power trading platform service of the present invention through a simple image.

Referring to Figure 1, the P2P power trading platform service server (hereinafter abbreviated as service server 100) of the present invention is generally used in the power of public institutions that produce and sell or provide power (for example, Korea Electric Power Corporation). Unlike power trading, it is a server that generates electric energy on its own or provides services to enable power trading between users and users who consume the generated electric energy.

How the service server 100 provides these services to users will be explained in detail below. Before providing a detailed explanation, let's first look at terms frequently used in the service server 100 to help understand the explanation. .

[Service Server (100)]

The service server 100 is a server that provides various interfaces and transaction matching services so that P2P power transactions between users can be performed easily or conveniently. The control server 200 manages a large amount of transaction transactions, and the third server provides predictive analysis of transaction prices. The party server 300 is connected to the ESS 400, which stores surplus power on behalf of the user, and is also configured to provide these additional services to users using the power trading platform.

[Information acquisition module (10)]

The information acquisition module 10 is a terminal-type device that can be installed in a user's building that produces or consumes power, and, like the service server 100, has various interfaces and can be compatible and linked with various servers. In addition, the information acquisition module 10 can store or analyze the power produced and consumed by the user, that is, the power generation information and consumption information in real time or for a preset time (can be set by the user), so that the user can This allows the generated power and consumed information to be seen at a glance, and this information can be transmitted and received with the service server 100, allowing P2P power trading between users.

[Control Server (200)]

The control server 200 manages and controls transaction transactions so that the service server 100 can smoothly conduct P2P power transactions between users. Specifically, the control server 200 can be viewed as a control room that manages and controls P2P power transactions. It manages or controls matching power transactions in real time to detect transaction errors and find the cause of the detected errors. It plays a role in solving errors and preventing errors from occurring in advance. Furthermore, the control server 200 may also perform a crime prevention role in power trading, such as blocking users who commit deception or fraud in advance or finding users suspected of committing fraud.

[Third-party server (300)]

The third-party server 300 is a server that predicts and analyzes power transaction prices, and contains expert information that predicts and analyzes power prices that may change due to weather, climate, temperature, past transaction history, various events, accidents, etc. It may be a server equipped with AI or a server combined with AI that predicts and analyzes prices based on these factors and backgrounds. The information provided by the third-party server 300 will be of great help to users who are new to P2P power trading and businesses with relatively high power consumption.

[ESS (400)]

ESS (400) is an abbreviation for Energy Storage System and is a system mainly used to store surplus power. If you think about it from the perspective of a producer who produces electricity, since the sun sets during the day, there are few consumers who consume electricity, which leads to surplus power remaining unconsumed, and because the sun sets at night, there are many consumers who consume electricity. Rather, it can also occur when there is a lack of power. According to these power production and consumption patterns, it can be a good option for producers who produce and generate power to store surplus power generated during the day and resell it to power consumers at night, and the ESS (400) makes this possible. . This ESS (400), as the term suggests, is a system that stores energy and provides a service so that the producer who produces electricity can store and resell as much power as desired, and is linked to the service server (100) of the present invention to provide a service server (100). ) provides a service that allows users to store power used in transactions and power waiting to be used using the service server 100 linked to the ESS (400).

Above, we briefly looked at terms frequently used in how to provide P2P power trading platform services.

Next, before looking in detail at how to provide the P2P power trading platform service, let's look at the information acquisition module 10 in detail through FIGS. 2 and 3.

Figure 2 is a diagram showing the simplified components of the information acquisition module 10 through a schematic diagram.

As mentioned above, the information acquisition module 10 is a terminal-type device that can be installed in a user's building that produces or consumes power. Like the service server 100, it has various interfaces and can be compatible and linked with various servers. In addition, the power generated and consumed by the user, that is, the power generation information and consumption information, are stored or analyzed in real time or for a preset time (can be set by the user).

In order to know the role and characteristics of the information acquisition module 10 in detail, it would be desirable to understand the components of the information acquisition module 10, which will be explained below.

The information acquisition module 10 includes a communication unit 11, a storage unit 12, a calculation unit 13, a control unit 14, and an interface unit 15.

First, the communication unit 11 is a component designed to transmit the power generation information and consumption information measured and stored by the information acquisition module 10 to the user terminal (20: see FIG. 7) or to the service server 100. can see.

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

The storage unit 12 contains information about the power produced or developed by the user, information about the 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, the storage unit 12 has difficulty in data storage space to store all information on power generated and consumed in real time, and executing the task of storing power information too frequently causes unnecessary waste of resources. Therefore, the user can store information about power in preset time units (for example, every 15 minutes).

The calculation unit 13 generally performs the role of calculating and processing the information transmitted or received from the communication unit 11, and typically information about the power produced or generated by the user is exchanged with the service server 100. It plays a role in forming a blockchain between the information acquisition module 10 and the service server 100 by blocking the information about the power, or receives it from another power measurement device such as a solar inverter or meter. It performs the 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 responsible for the central processing of the information acquisition module 10. The control unit 14 is divided into a controller, microcontroller, microprocessor, microcomputer, etc. It can also be called . Additionally, the central processing unit may be implemented by hardware, firmware, software, or a combination thereof. When implemented using hardware, an application specific integrated circuit (ASIC) or a digital signal processor (DSP), When implemented using firmware or software such as a digital signal processing device (DSPD), programmable logic device (PLD), or field programmable gate array (FPGA), a module, procedure, or function that performs the above functions or operations is used. Firmware or software may be configured to include.

This 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 information developed or consumed by the user to the user in real time, or analyzes the obtained information and provides the analyzed information to the user. 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 the message queue method that provides the user with real-time storage and output of input values through messaging. In other words, information developed or consumed by the user is provided in real time. It is an interface that stores and provides said information to users through messaging.

The Open ADR interface (15b) is an abbreviation for Open Automated Demand Response interface. To put it simply, it is an interface that provides the user with signals that indicate the user's developed or consumed information. Furthermore, the Open ADR interface (15b) utilizes these signals to provide the user with signals. It is an interface that presents a plan to optimize power generation or consumption, or suggests an efficient power generation or consumption plan.

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 price of power to the user and efficiently provide power. It is an interface that suggests ways to purchase.

The SEP interface (15d) is an abbreviation for Smart energy profile interface, which not only plays a role in controlling smart energy-related data and related devices (solar inverters, meters), 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.

The OBIX interface (15e) is an abbreviation for Open Building Information Exchange interface, and is a web-based building management system. Like the interfaces described above, it analyzes the power information obtained from the information acquisition module (10) and provides the analyzed information to the user. It is an interface that

Meanwhile, Figure 3 shows specific components of the information acquisition module 10 through a schematic diagram, and if the information acquisition module 10 is actually implemented, it may include more components as shown in Figure 3. For reference, it is understood that Autonerv depicted in the drawing 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 components shown, and that some components may be added or deleted.

Above, we have looked in detail at the information acquisition module 10 of the method of providing the P2P power trading platform service of the present invention.

Next, let's look at the components of the service server 100 of the present invention in detail through FIGS. 4 and 5.

Figure 4 is a diagram showing the simplified 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 power transactions between users can be carried out easily or conveniently. Like the information acquisition module 10 described above, it is linked to various servers or devices to provide information to users. Additional services can be provided.

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

First, the communication unit 110 basically performs the role of ensuring communication with servers such as the user terminal 20, the third-party server 100, and the ESS 400 so that the user's P2P power transaction can take place.

The user terminal 20 of the communication unit 110 receives the user's purchase or sale request, energy storage request through the ESS 400, and the third-party server 100 allows exchange of power price analysis information. In addition, relevant information is exchanged with the ESS (400) to mediate energy storage between the user and the ESS (400).

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

Meanwhile, the calculation unit 130 stores the information stored in the storage unit 120 in blocks so that a blockchain can be formed, and processes calculations to perform a transaction matching algorithm that will 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 description will be omitted.

Next, the interface unit 150 is a user interface or software interface provided to users so that users using the service server 100 can easily use the P2P power trading service, and includes 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 power trading platform as an application so that the user can easily use the P2P power trading platform on the user terminal 20. Through the application, the user can use the power trading platform. You can sign up for membership, request to purchase or sell, suggest sales or purchase amounts, and modify purchases or sales.

The interactive interface 150b is a user interface that allows a conversation between a user and another user, or a conversation between a user and a platform manager, to take place on the power trading platform, and the user communicates with another user through the interactive interface 150b. By exchanging, each party's desired price and conditions can be presented to facilitate transaction matching, and by allowing users to communicate with the administrator, errors that arise when users use the power trading platform, etc. Allows the manager to accept and process it quickly.

VPP interface (150c) is an abbreviation for virtual power plant interface and refers to a virtual power plant interface. The VPP interface 150c, which is a virtual power plant interface, performs the role of observing and controlling power information generated from distributed energy resources in real time. In other words, it is an interface used to monitor and control in real time the power information acquired by the information acquisition module 10, which is power information about distributed energy resources.

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 will be omitted.

Meanwhile, 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 explanation in this detailed description, so detailed information will be provided. Mention will be omitted.

Above, we have looked at the service server 100 in detail in the method of providing the P2P power trading platform service of the present invention.

Next, let's look at a method of providing a P2P power trading platform service according to the first embodiment of the present invention.

[First Example: Basic Process]

Figure 6 is a diagram specifically showing a method of providing a P2P power trading platform service according to the first embodiment of the present invention.

In the method of providing the P2P power trading platform service according to the first embodiment of the present invention, the service server 100 presents a basic process by which the P2P power trading platform is provided to the user. Hereinafter, the P2P power trading platform is provided to the user. Let’s look at the methods in detail in order.

The method of providing a P2P power trading platform service according to the first embodiment of the present invention begins with the step (S101) of storing the power information acquired by the information acquisition module 10 in blocks for each previously stored time. Here, the power information may be information that produces power or information that consumes power, and power-related information (power consumption analysis, power price prediction, etc.) obtained from various interface units 15 associated with the information acquisition module 10. It may be, etc. In addition, blocking each previously saved time means forming a blockchain by blocking the information used in power trading. This will improve the reliability of users by ensuring that the P2P power trading platform is secure based on blockchain. It becomes a possible factor. On the other hand, if the service server 100 blocks all information in real time to form a blockchain, not only will the blocked information become massive, making it difficult to search for related information, but there will be insufficient storage space to accommodate the blocked information in the future, so In preparation for a situation in which power trading cannot be performed, the service server 100 can specify a pre-stored time, that is, a specific time or cycle, to separate information at each designated time and block the classified information.

After the power information acquired by the information acquisition module 10 is stored in blocks for 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 blocked power information in step S102. Even if the information acquisition module 10 only acquires the power information in step S101 and does not block it, the service server 100 receives the information in step S102. The power information received from the acquisition module 10 may be implemented in blocks for each previously stored time.

Next, 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 from a seller who generates or sells electricity, or a purchase request from a buyer who purchases and consumes electricity. A sales request may include a sales price, sales quantity, etc., and a purchase request, like a sales request, may include a purchase price, purchase quantity, etc. Additionally, a transaction request may be a request for the seller and buyer to mediate each other's transactions if a mutual transaction agreement has already been reached between the seller and 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 the transaction based on a pre-stored algorithm and settles the matched transaction (S104). Here, the previously stored algorithm can be an iterative multiple auction method algorithm and a spline-type automatic purchase price determination algorithm, and the algorithm that includes the intervention of a third-party server described above can be used.

When the service server 100 matches a transaction based on a pre-stored algorithm and settles the matched transaction (S104), the service server 100 blocks the transaction record and stores it (S105). First embodiment of the present invention The P2P power trading platform service provision method is finalized.

Above, we have looked at the method of providing P2P power trading platform services according to the first embodiment of the present invention.

Next, let's look at the method of providing P2P power trading platform services according to the second embodiment of the present invention.

[Second Embodiment: Embodiment 1]

Figure 7 is a diagram specifically showing a method of providing a P2P power trading platform service according to a second embodiment of the present invention.

If the P2P power trading platform service providing method according to the first embodiment of the present invention is the basic process of the basic P2P power trading platform service providing method, the P2P power trading platform service providing method according to the second embodiment of the present invention is the first implementation. An example is an embodiment embodied in the interaction between the information acquisition module 10, the service server 100, and the user terminal 20, and will be described below.

The method of providing a P2P power trading platform service according to the second embodiment of the present invention begins with the step (S201) in which the information acquisition module 10 collects power information in real time. At this time, the information acquisition module 10 is installed in buildings such as houses, commercial buildings, and public facilities of buyers or sellers who want to trade electricity, and the installed information acquisition module 10 collects information on power generation and consumption in real time. do.

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

When the information acquisition module 10 blocks and stores the power information for each previously 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 makes a transaction request for a sales request 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 the transaction based on a pre-stored algorithm (see FIGS. 8 to 12) and performs matching. Settlement the transaction (S207).

When the service server 100 matches a transaction based on a pre-stored algorithm and settles the matched transaction (S207), the service server 100 blocks the transaction record and stores it (S208). Second embodiment of the present invention The P2P power trading platform service provision method is finalized.

Above, we have looked at the method of providing P2P power trading platform services according to the second embodiment of the present invention.

Next, let's look at the method of providing P2P power trading platform services according to the third embodiment of the present invention.

[Third Embodiment: Pre-stored Algorithm (Iterative Multiple Auction Algorithm)]

Previously, it was explained that a pre-stored algorithm is used to match P2P power trading in the first and second embodiments of the present invention, and the method of providing a P2P power trading platform service according to the third embodiment of the present invention uses the pre-stored algorithm. An iterative multiple auction algorithm is proposed. Here, in the repeated multiple auction method, the buyer makes a purchase request by bidding on the purchase price and purchase quantity, and the seller requests a sale by requesting the sale price and sales quantity (Ask), and the service server 100 sends this transaction request. Store and sort sales requests in descending order of sales price, and sort purchase requests in descending order of purchase price, match sales requests with the lowest selling price and purchase requests with the highest purchase price, calculate the average price of the two, and calculate the average price. The transaction is allowed to proceed, and the smaller of the sales volume and the purchase volume is designated as the settlement volume, and the transaction is settled by the designated settlement volume. After settlement, if there is a remaining transaction volume among the seller's sales volume or the buyer's purchase volume, another user is re-registered for the remaining transaction volume. It is a transaction matching method that matches.

Looking at the repeated multiple auction method of the P2P power trading platform service provision method according to the third embodiment of the present invention in detail with reference to FIG. 8, first, the service server 100 receives the sales request from the user terminal 20. It begins with the step of sorting sales requests in order of lowest sales price (S301).

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

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

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

The service server 100 checks whether there are remaining sales requests or purchase requests for another matching (S304), and if there are remaining sales requests 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.

Meanwhile, when the service server 100 records a matched transaction, the service server 100 deducts the sales and purchase amounts by the settlement amount (S305). Here, the settlement amount is the smaller of the sales volume and the purchase amount. If the sales volume the seller wants to sell is "7kWh" and the purchase amount the buyer wants to purchase is "3kWh," the settlement amount will be the smaller value between the sales volume and the purchase volume, which is "3kWh". , the amount will be deducted by the settlement amount, so the sales volume will be “4kWh” and the purchase volume will be “0kWh.”

Next, when the service server 100 deducts the sales and purchase quantities by the settlement amount (S305), the service server 100 brings the next sales request or purchase request when the sales or purchase amount becomes “0” (S306). .

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

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

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

Above, through Figures 8 and 9, we looked at a method of providing a P2P power trading platform service according to the third embodiment of the present invention.

Next, let's look at a method of providing a P2P power trading platform service according to the fourth embodiment of the present invention.

[Fourth Embodiment: Pre-stored Algorithm (Spline Price Curve Algorithm)]

The method of providing a P2P power trading platform service according to the fourth embodiment of the present invention is one of the stored algorithms for matching P2P power trading, and automatically calculates sale/purchase prices using a spline function. It's an algorithm.

First, to understand how to provide a P2P power trading platform service according to the fourth embodiment of the present invention, you must first understand the spline function.

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

Using the concept of this spline function, we will explain the automatic sale/purchase price calculation algorithm of the P2P power trading platform service according to the fourth embodiment of the present invention.

Figure 10 is a diagram showing a method of automatically calculating sales/purchase prices through this spline function.

Referring to Figure 10, in the method of automatically calculating the sale/purchase price through a spline function, first, the seller or buyer selects a reference point by determining the sale/purchase price and sale/purchase time desired. In Figure 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. was chosen.

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

In this way, the formed spline price can calculate the price at the time of sale or purchase. Specifically, referring to Figure 10, "P12" is the price decision point for 10:00, the time zone between "P1" and "P2" selected by the seller or buyer, and this decision point is the price decision point through the spline price curve. You can see that it is calculated as “100 won”. Similarly, "P23" is the price decision point at 15:00, 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. You can see that

Meanwhile, the seller or buyer can reset the previously 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.

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

Referring to FIG. 11, the user can reset the pre-selected reference point by dragging through the 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'" in FIG. 11 through the user's drag. For reference, only the price has been reset for "P1" and "P2", and only the time zone has been reset for "P3", but both price and time zone can be reset by the user's drag, and the reference point will remain the same as in "P4". It may be possible.

In this way, when the user resets the reference point by dragging, the service server 100 generates 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.

Above, through Figures 10 and 11, we have looked at a method of providing a P2P power trading platform service according to the fourth embodiment of the present invention.

Next, let's look at a method of providing a P2P power trading platform service according to the fifth embodiment of the present invention.

Figure 12 is a diagram specifically showing a method of providing a P2P power trading platform service according to the fifth embodiment of the present invention.

The method of providing a P2P power trading platform service according to the fifth embodiment of the present invention involves receiving third-party information from the third-party server 300 after the service server 100 matches the transaction between the seller and the buyer. This is an example of a method of settling transactions based on third-party information.

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

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

Next, 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 provided additionally to users who use the P2P power trading platform. In general, it is natural for buyers to try to purchase power at a low price and sellers to sell power at a high price. Depending on the purpose, the transaction matching amount will inevitably decrease. In particular, this phenomenon is bound to become more serious depending on certain situations. For example, when power consumption for heating facilities increases due to a continuous cold wave, there may be sellers who take advantage of this and try to sell power at a high price, and relatively low power consumption may occur. In the spring, fall, and during daytime hours when it is not needed, there are bound to be many buyers who want to purchase electricity at a low price. These situations make it difficult to satisfy both the seller and the buyer. Accordingly, the service server 100 is linked to a third-party server 300 that objectively analyzes the price of electricity according to various situations, receives third-party information transmitted by the third-party server 300, and receives the received third-party information. Based on this, we can provide a service that settles transactions and presents a price that satisfies both buyers and sellers.

Next, 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 small fee may also be paid to the third-party server 300 that provided the third-party information. In other words, if the parties to the transaction benefited from the transaction by referring to the information provided by the third-party server 300, the third-party server 300 will naturally receive a commission accordingly. Payment methods can be determined in various ways. For example, if a transaction is made with reference to the above information, a certain percentage of the transaction amount may be paid to the third-party server 300, or a fixed amount may be paid each time a transaction occurs regardless of the transaction amount. This may be paid. Alternatively, only parties who wish to use third-party information may be required to pay a small subscription or usage fee.

Above, we have looked at a method of providing P2P power trading platform services according to the fifth embodiment of the present invention.

Next, let's look at a method of providing a P2P power trading platform service according to the sixth embodiment of the present invention.

Figure 13 is a diagram specifically showing a method of providing a P2P power trading platform service according to the sixth embodiment of the present invention.

In the method of providing a P2P power trading platform service according to the sixth embodiment of the present invention, when the service server 100 is linked with the ESS 400 and receives a surplus power storage request from the user, the fee among the surplus power storage requests is measured to be high. This is an example of a method of sorting requests in order, transmitting the sorted requests to the ESS (400), and storing surplus power in the order of the sorted requests by the ESS.

As explained previously, ESS (400) is an abbreviation for Energy Storage System (Energy Storage System) and is a system mainly used to store surplus power, and can be used as a public ESS (400) in connection with the service server (100). You can.

Since the method of providing the P2P power trading platform service according to the sixth embodiment of the present invention is the same as the method of providing the P2P power trading platform service according to the second embodiment of the present invention up to step S405, steps S405 and S405 Only the subsequent steps will be explained.

After the service server 100 receives the blocked power information from the information acquisition module 10 (S404), if the user terminal 20 requests to store the surplus power (S405), the service server 100 stores the surplus power. Save the power storage request (S406).

When the service server 100 stores the surplus power storage request (S406), the service server 100 sorts the surplus power storage requests in order of the highest commission and transmits the sorted requests to the ESS 400. Do it (S407).

When the service server 100 transmits the sorted requests to the ESS 400 (S407), the ESS 400 receives the sorted requests and stores surplus power in the order of the sorted requests (S408) of the present invention. The method for providing the P2P power trading platform service according to the sixth embodiment is completed.

Above, we have looked at a method of providing a P2P power trading platform service according to the sixth embodiment of the present invention.

Next, let's look at a method of providing a P2P power trading platform service according to the seventh embodiment of the present invention.

Figure 14 is a diagram showing a method of providing a P2P power trading platform service according to the seventh embodiment of the present invention.

The method of providing a P2P power trading platform service according to the seventh embodiment of the present invention involves the service server 100 generating a token to be provided to the user according to a pre-stored standard after the P2P power trading is completed and delivering the token to the user. This is an example of the method.

The method of providing the P2P power trading platform service according to the seventh embodiment of the present invention is the same as the method of providing the P2P power trading platform service according to the second embodiment of the present invention up to the steps before S502, so steps S502 and S503. Only the subsequent steps will be explained.

After the service server 100 blocks and stores the transaction record, the service server 100 generates a token according to the previously stored criteria (S502). Here, the previously stored standard can be one token paid per 1 kWh of electricity consumption, and the higher the winning rate, the more tokens paid. More diverse standards can be applied to encourage users to use more renewable energy. .

Next, when the service server 100 generates a token according to a pre-stored standard (S502), the service server 100 records the generated token in the blockchain to form a blockchain (S503).

When the service server 100 records the generated token in the blockchain to form a blockchain (S503), the service server 100 delivers the token to the user terminal 20 (S504).

We have looked at all the methods and systems for providing P2P power trading platform services. The present invention is not limited to the specific embodiments and application examples described above, and various modifications can be made by those skilled in the art without departing from the gist of the invention as claimed in the claims. Of course, these modified implementations should not be understood separately from the technical idea or outlook of the present invention.
