Step (S220), providing a 2D or virtual space so that the seller and the buyer can conduct business tours and meetings in a virtual environment (S230), and allowing a transaction between the seller and the buyer to occur through the transaction space (S240) ) and, when a transaction is completed at a transaction meeting hosted in the virtual space, a step (S250) of calculating and outputting the registration fee, sales fee, consulting fee, and related company promotional fee according to the presented transaction price information. Registration fees, etc. may be required to be paid in advance at the necessary stages for transaction.

Since the energy traded in the present invention ultimately corresponds to electricity (electric power), it can be configured to use the KEPCO grid as a trading infrastructure, but it is not necessarily limited to this and other power exchange networks (e.g. smart grid) can be used. It can be.

Additionally, in the present invention, a producer unique code and a consumer unique code can be assigned and used when authenticating a prosumer. For example, when trading energy in the energy trading system 10 of the present invention, when the seller and the consumer accept the transaction terms and each enter a unique code, the seller's energy reserves decrease by the amount sold in the energy network of the power exchange and the consumer The holding amount can be configured to increase by the purchase amount (sale amount).

That is, in the energy trading system of the present invention, for example, when energy transactions are made within KEPCO's power grid, the amount of energy held increases or decreases, just as cash is deposited or withdrawn from a financial institution's bank account through an online financial transaction, thereby increasing the number of sellers and consumers. It can be configured in a way to check the quantity of energy held, and can be configured so that both sellers and consumers, as prosumers, can sell the remaining energy that is deducted from sales or use.

Meanwhile, a Renewable Energy Certificate (REC) is a certificate that proves that energy has been supplied through a renewable energy facility, and the energy trading system of the present invention can also be configured to enable energy trading based on REC. At this time, RECs are issued to sellers by power exchanges such as KEPCO, and buyers can purchase energy by receiving RECs from sellers. However, REC is only an example, and symbols, codes, numbers, or blockchained certificates that can certify that power data can be supplied may be used.

In the present invention, electricity sales and payment for purchased electricity can be configured to be possible based on these RECs. Specifically, sellers can sell RECs and consumers can pay for energy based on RECs.

In other words, in the present invention, consumers and sellers sell and make payments based on REC, and for the amount of electricity purchased, the consumer can deduct and settle the purchased power along with the general electricity bill to a power exchange such as KEPCO.

In the energy trading system of the present invention, numbers are assigned to LOTs or batches that can produce and sell energy, and can be configured to sell as much as the capacity corresponding to the LOT/batch. In other words, in the present invention, rather than a direct physical connection between electricity producers and sellers, the electricity moving is quantified/dataized and transacted using the network of an established power exchange such as KEPCO. Since the movement path of electricity and the transaction path between sellers and consumers on the trading system platform are different, it becomes possible to trade electrical energy without the need for the production and consumption sites to be physically connected directly.

In the case of KEPCO and KEPCO KDN, power generation is controlled and supplied by predicting power consumption patterns. KEPCO or KEPCO KDN's electricity supply method is to manage production and supply by predicting demand information from the producer and seller's perspective, thereby providing renewable energy. Despite the failure to predict demand and supply, which impedes the development of the production capacity of electricity generation producers and fails to predict demand and supply, the possibility of improvement is low compared to the producer competitive market because it is a monopoly market. However, in the energy trading system according to the present invention, individual power generation facilities By making it possible to trade energy reliably in this direct market, the problems caused by the monopoly of such energy sales networks can be resolved to some extent.

To explain in more detail how to use the KEPCO grid network in the energy trading system of the present invention, using the KEPCO grid network spread across the country, the electricity producer supplies electricity to KEPCO, and the amount of electricity transmitted to KEPCO Regarding this, KEPCO receives a unique symbol, code, or number for the data, or receives a blockchain certificate, and the electricity producer provides the above authentication symbol, code to the electricity consumer/buyer matched in the energy trading platform of the present invention. , numbers, or blockchain-enabled certificates can be presented to sell new and renewable energy. Afterwards, the buyer can present the data equivalent to the purchase amount to KEPCO and deduct the payment from the monthly electricity bill.

In addition, in the energy trading system of the present invention, power exchanges and telecommunication companies such as KEPCO, which provides a grid network for electricity sales and payments, identify producers (sellers) and consumers (buyers), i.e. prosumers, with unique numbers/symbols. It can be configured to identify.

In the present invention, in addition to grid network providers such as KEPCO, other power exchanges, electricity storage such as energy logistics warehouses, and energy storage distribution operators can participate in transactions for transmission and storage of traded energy.

The energy trading system of the present invention is easy for anyone to register and use as an electricity seller, and even the elderly, women, and young people who do not know much about electricity or technology can easily access and use it as consumers, allowing people of all ages and genders to take the lead in using electricity. do.

The energy trading system server 10 of the present invention can post the average of energy prices every day or over a predetermined period and allow consumers or sellers to inquire about price changes. The energy trading system server 10 of the present invention can display prices or price changes in graphs, numbers, etc., and can also display prices offered by sellers and consumers.

In addition, in the energy trading system of the present invention, the purchase amount is calculated based on the consumer's monthly or annual electricity consumption, and the system can recommend a purchase place. If the amount of electricity purchased by the consumer exceeds the amount used, the surplus is registered for sale. You can also resell it.

In addition, according to the energy trading system of the present invention, not only energy transactions between sellers and consumers located in nearby areas are possible, but also transactions at a national level are possible, thereby expanding the renewable energy market and enabling users to purchase and use the necessary electricity. Users can choose the renewable energy source and price they want, and sellers can connect with various consumers.

In addition, since most of them use networks/grids that are already installed and use existing network technology, the effect of reducing the burden of installing additional power supply networks can be expected.

On the other hand, by adopting the energy trading system of the present invention, at a time when fundamental innovation in energy production and sales is needed in response to climate change, anyone who uses electricity can safely and quickly use the platform, moving away from the unification of power generation sellers. It can be said to be desirable in that one can select and control one's own electrical energy. On the one hand, as the purchasing market for new and renewable energy expands, the number of sellers of new and renewable energy can increase. On the other hand, it increases the production desire of buyers, allowing them to become sellers by equipping themselves with new and renewable energy production facilities.

In the present invention, when registering as a member of a system for renewable energy trading, the subscriber is asked whether he or she is an energy producer or buyer and can select it. If a subscriber is both a producer and a buyer, it can be configured to select both.

Producers who want to sell energy can select and input the energy source they produce and configure it to input the average daily production or monthly average production for each unit period. In addition, the producer can be configured to select and input the amount of electricity and storage capacity sent to KEPCO, the sales volume can be separately entered among the production, and the desired sales price can be input.

All of these input methods can be configured so that the inputter can choose between a given value and a direct input method, and when entering the desired selling price of energy, the price announced by the energy trading system 10 of the present invention It can be used for reference.

Meanwhile, energy purchasers (consumers) may be configured to input the amount of electricity used per unit period, for example, the previous month or the annual average, the amount of electricity to be purchased, and the energy source.

The energy source entered by the purchaser can be input by setting preferences such as wind power, solar power, biomass, etc. (e.g. solar power first, biomass second, wind power third, etc.).

Additionally, when the buyer inputs the amount of electricity he or she wishes to purchase, a list of producers that can sell electricity that is 100% to 120% or more of the input amount of the required electricity can be automatically extracted and provided to the buyer.

At this time, the automatically extracted producers can be classified and provided based on the location distance from the buyer, and the buyer can have the producers extracted by sorting only the producers within a certain distance.

In addition, the buyer can have the producer extracted based on the producer's energy sales price, and in this case, the buyer can receive a sales price within a predetermined range, for example, -10% to +20%, based on the average published energy value of the day. It can be configured to extract only producers who offer , or the system can match and recommend producers who offer a sales price that is closest to the consumer's desired input price.

In this regard, when the system for new and renewable energy trading of the present invention is adopted, a solution that can cover 100% of the energy needed by consumers based on data on the consumer's average monthly electricity usage, purchase needs, annual purchase amount, etc. can be presented. Meanwhile, based on the consumer's purchase history, the consumer's energy purchase pattern, consumer's requirements (desired energy source, price, energy amount, distance from seller, seller's available energy for sale/time of sale, etc.) Based on the company's reliability, including the stability of energy supply, it is possible to match consumers with the optimal energy seller.

In addition, when matching a seller and a consumer, the “matching score”, which indicates the transaction suitability of both parties, is the seller's score that reflects the seller's reliability, including the seller's response rate, response reliability, energy quality, etc. (i.e. , prosumer score, return score), etc. are taken into consideration, and as before, the consumer's energy purchase pattern, consumer's requirements (desired energy source, price, energy amount, distance from seller, seller's energy available for sale/sale) It can be configured to be calculated according to the time point, etc.).

For example, if the energy source that a consumer wishes to purchase is solar power, a seller who can sell electric energy from solar power may be assigned an energy source matching score of 100%. Additionally, if the seller's energy production/sales volume can cover 100% of the consumer's energy purchase/consumption volume, a capacity matching score of 100% may be assigned. Of course, in addition to %, the matching score may be expressed as an integer such as 0 to 100, a decimal, or a fraction. Additionally, in the case of a seller that can only sell a small amount of the product below the capacity desired by the consumer, a matching score equal to the corresponding percentage (e.g., 50%) may be assigned.

A matching score based on the physical distance between the consumer and the seller may also be assigned a distance matching score in inverse proportion to the distance. For example, if it is 0 to 10 km or less, it is 100%, if it is more than 10 but less than 30 km, it is 70%, and if it is more than 30 but less than 50 km, it is 50%.

Alternatively, additional distance matching points may be assigned on an administrative district basis. For example, sellers in the same city may be given additional points. The size of the additional points may be set in inverse proportion to the size of the administrative district unit to which both the seller and the consumer belong. For example, if they are located in the same district, a larger additional point may be given compared to when they are located in the same province.

Meanwhile, in addition to transactions other than professional producers and individual buyers, the matching score is 1 when two small producers transact with one party as a consumer (e.g., a transaction between small power generation facilities) or, conversely, when general consumers transact energy through self-generation. Additional points can be given in case 2 (e.g. household-to-household energy trading). Since this matching score is generally a transaction method in which consumers select a seller, it will generally be given to the seller. Therefore, in cases 1 and 2 above, additional points can be given to the small power generation facility and the household as the seller. In order to ensure the reliability and fairness of awarding these additional points, the energy trading system of the present invention performs a certification process for the seller's production facilities or production capacity and the average amount of electricity consumed by the consumer at the time of membership registration, and the authentication is carried out between the seller and the consumer. It can be configured to be performed based on data submitted by users who wish to sign up. In other words, when calculating the prosumer score, the prosumer's information can be evaluated objectively.

Meanwhile, in online energy trading, it is necessary to certify the reliability of whether the seller's products are tradable, that is, the reliability of the seller and the reliability of the energy being sold. In other words, due to the nature of online transactions and the nature of an intangible object called energy that cannot be traced, authentication of the transaction possibility or reliability of the seller and the energy sold is necessary.

To this end, the present invention can be configured to authenticate whether the seller is double-dealing with a limited amount of electricity. For example, if the electricity sent to KEPCO, etc. is 50kw, the amount of electricity that the seller can sell must be limited to 50kw, and sales may be restricted so that even 50kw of electricity cannot be traded repeatedly. In addition, in order to prevent duplicate transactions and to prevent additional transactions before sales transaction approval is completed, if 30 kw of the 50 kw available for sale are in progress, 30 kw is in a transaction process and is therefore configured to be converted to an inactive state where transactions are not possible. The capacity (e.g., 20kw) may be configured to be displayed separately.

In addition, the energy trading system of the present invention may additionally include a system for authenticating whether the seller prosumer is a legitimate producer and seller capable of selling energy using a business registration certificate, etc.

Meanwhile, the prosumer score is calculated based on the feedback score, that is, including the feedback score, and the prosumer score indicates the reliability of how competitive the transaction is, and can be configured to be linked to the feedback score. However, the prosumer score is calculated excluding the feedback score if there is no existing transaction, and the feedback score can only be calculated if there is an existing transaction. This is because the feedback score is evaluated based on the other party's experience in the existing transaction. Because it is a score that is acceptable.

A prosumer's trustworthiness can be scored from the beginning using information entered and company data even without transaction experience, so the prosumer score can be calculated even without an existing transaction. The prosumer score is calculated to evaluate prosumers based on non-transaction items such as the number of transactions, the number of items to enter authentication information for prosumer registration, the fidelity of information input, and the size and year of establishment of the production facility.

The matching score indicates the suitability of both parties to the transaction, and even if each of the two prosumers has a high score, the score is not necessarily high when the two are matched.

Ultimately, in the energy trading system of the present invention, the matching score is calculated by considering both the evaluation score of the prosumer using non-transaction information (prosumer score) and the feedback score resulting from the transaction information, so energy trading is unfamiliar and difficult to trust for the general public. The environment can be improved to be more consumer-friendly than before, and energy trading can be revitalized through this.

In addition, according to the present invention, power producers can participate in transactions if they wish, regardless of the size of the production facility, and there is no need to physically connect the power grid between prosumers.

The memory unit may include a database for structuring and storing various types of information and providing search and update functions.
