6 is a view showing an energy trading system according to an embodiment of the present invention.

Referring to FIG. 6, the energy trading system of the present embodiment may include a plurality of smart gateways and a transaction intermediary server. Depending on the embodiment, the transaction brokering server may be omitted.

The smart gateways and the transaction brokerage server may be interconnected via a network. Here, the network is not limited as long as it can interconnect the smart gateways.

According to an embodiment, the smart gateways are devices installed in homes, buildings, and the like, and may include an energy trading unit for a platform and energy trading. Here, the energy trading unit may be implemented in hardware or only in software. In addition, the energy transaction unit may be a separate module separate from the smart gateway.

Hereinafter, for convenience of description, it is assumed that the energy transaction unit is included in the smart gateway. At this time, the energy transaction program (application) of the energy transaction unit may be installed, updated, or deleted through a management server.

According to an embodiment, the smart gateways may perform energy trading through a P2P method or the transaction brokering server using their energy trading program. In particular, in the case where the smart gateways are devices installed in a home, energy transactions are possible even for individuals.

Specifically, when an energy transaction is requested from the first smart gateway, the transaction may be performed by the second smart gateway connected to the first gateway accepting the transaction. In this case, the smart gateways may be devices equipped with the same platform.

For example, when the first smart gateway announces that it will sell energy at a specific price, a transaction may be made by one of the smart gateways connected or connectable to the first smart gateway accepting the transaction. The disclosure may be shown on a page provided by the transaction brokerage server, or may be displayed on smart gateways of a group to which it belongs, smart gateways connected to itself or smart gateways of the region to which it belongs. Due to the nature of energy trading, energy trading between smart gateways that are too far away is inefficient, so that transactions can be made between smart gateways within a certain distance.

That is, if smart gateways can use the energy trading program installed on them to conduct energy trading, the method of sales disclosure and acceptance can be variously modified.

As another example, when the first smart gateway discloses that it wants to purchase energy by specifying a region, price, quality, or region, a transaction may be made by one of the smart gateways that can sell energy accepting the transaction.

As another example, when the first smart gateway announces a transaction request to purchase energy, other smart gateways may present a price, etc., and the first smart gateway takes into account the suggested price, etc. Transactions can be realized.

As another example, energy transactions may be made at a price suggested to each other between smart gateways, but the smart gateways may negotiate a price based on the suggested price, and energy transactions may be made at the negotiated price. That is, negotiations for energy transactions can be made between smart gateways to be traded. For example, if a smart gateway announces that it wants to purchase energy and b accepts that the smart gateway will sell energy, a smart gateway and b smart gateway can negotiate energy prices and conduct energy transactions at negotiated prices. have.

Above, energy transactions are mainly mentioned based on price, but due to the nature of energy transmission, it is necessary to consider not only price, but also various transmission distances, facility quality, time, and energy quality.

According to one embodiment, when an energy transaction is completed, energy must be transmitted to an energy buyer, and energy loss may occur in the process of energy transfer. In particular, energy loss may vary depending on transmission distance, facility quality, and the like. Therefore, the smart gateway or the energy intermediary server may determine whether the energy price and the transaction are successful in consideration of transmission distance, facility quality, energy quality, and the like.

For example, when the transmission distance is 100 meters and the price for transmitting 1 kwh of energy is 3000 won, when the transmission distance is 500 meters, the price for transmitting 1 kwh of energy may be 5000 won. That is, as the transmission distance increases, the energy price may increase even if the energy is the same. Here, information such as the transmission distance, facility quality, and time may be achieved through information exchange between smart gateways, or information provided by an energy intermediary server.

As another example, when the energy price is 3000 won when transmitting 1 kwh of energy in the morning in the summer, the energy price may be 3500 won when transmitting 1 kwh of energy at night. This is because more energy is expected to be consumed at night.

As another example, even if a smart gateway presents 3000 won per 1 kwh and b smart gateway presents 4000 won per 1 kwh, if the distance to a smart gateway is 5 km and b to the smart gateway is 500 m, the energy buyer You can also conduct energy transactions with a short distance b smart gateway.

As another example, even if a smart gateway presents 3000 won per 1 kwh and b smart gateway presents 5000 won per 1 kwh, b if the energy provided by the smart gateway is higher than the energy provided by a smart gateway, energy Buyers can also conduct energy transactions with b Smart Gateway, which provides quality energy regardless of price.

In this way, the price of energy that varies depending on transmission distance, facility quality, time, etc., can be specifically disclosed in the energy transaction. Therefore, an energy buyer can perform an optimal energy transaction in consideration of a distance to a smart gateway, a facility quality, a time, an energy quality, an energy type, etc. to be purchased.

According to another embodiment, not only the user of the smart gateway at the time of energy transaction, but also a provider providing a service through the smart gateway may participate in the energy transaction.

For example, when the first operator uses a lot of network load in providing a service using the first smart gateway or wants to use more capacity than the set load capacity, the first operator compensates for using the network load As a result, when purchasing energy from the second smart gateway, at least a portion of the purchase cost may be borne. That is, it can be said that a first operator providing a service through the first smart gateway participates in an energy transaction.

At this time, when the energy transaction, the first operator may directly transfer the amount to the account registered by the second smart gateway, or may pay the amount to the user of the first smart gateway after the energy transaction is made. Of course, there can be various ways to pay the reward. Of course, the first operator may provide energy in exchange for compensation, rather than remitting the amount.

As another example, when a service provider providing a service through a first smart gateway uses more network load than a preset capacity, when the first smart gateway purchases energy from another second smart gateway, it corresponds to the excess network usage. The amount of money may be automatically paid to the user of the second smart gateway.

On the other hand, although mentioned above as a network load, various factors necessary to provide a service in addition to the network load are considered, and compensation for the factors can be made in the energy transaction.

According to another embodiment, when an operator provides an advertisement to a user through a smart gateway and the user views the advertisement, the operator will pay at least a portion of the transaction price when the smart gateway exchanges energy with another smart gateway. It might be.

In the above, it was a method in which the operator bears at least a part of the transaction price when trading energy, but the operator may purchase energy and provide it to the user of the smart gateway as the compensation.

According to another embodiment, blockchain technology may be applied between smart gateways. For example, an energy transaction may be performed between two smart gateways while a specific group of smart gateways share information related to the energy transaction.

According to another embodiment, the transaction price and whether the transaction is successful may be changed according to energy quality (which can be confirmed in an energy tag), history, environment, and the like.

For example, if a consumer who wants to buy energy wants only high quality energy, only a seller with high quality energy can be traded regardless of the energy price. Of course, the price may vary depending on the energy quality.

As another example, if a consumer wants to purchase only renewable energy excluding energy produced by coal or thermal power, only sellers with renewable energy may be subject to the transaction. At this time, the transaction price of renewable energy may be higher than that of coal or thermal energy.

As another example, when a consumer wants to purchase only energy supplied from KEPCO, only a seller having energy supplied from KEPCO may be subject to the transaction.

These trading standards may be presented in advance and an energy transaction may be made, or in the course of an energy negotiation, such trading standards may be presented or an energy transaction may be canceled if the trading standards are not met.

On the other hand, although it is mentioned that the energy transaction is between two gateways, it does not exclude the transaction between three or more gateways. The above embodiments may also be applied to three or more gateways.

In addition, although energy transactions are mainly described above through public disclosure, energy transactions may be made by directly negotiating with each other between specific smart gateways. At this time, for the energy transaction, smart gateways exchange energy information including mutual energy details. For example, the first smart gateway sends an energy transaction request message to a second smart gateway, and the second smart gateway sends energy information including energy price, quality, and region to the first smart gateway, and the first smart gateway The smart gateway transmits an acceptance message to approve the transaction to the second smart gateway, pays for the energy transaction, and provides energy to a user or a designated location of the first smart gateway under the control of the second smart gateway. You can. Meanwhile, energy information may be provided as a tag when transmitting energy.

In addition, when energy transactions are established and energy is transferred, energy transfer may not be normal and may be interrupted in the middle. For example, a transaction in which the first smart gateway sells energy to the second smart gateway has been established, but may be stopped while energy is being transmitted from the first smart gateway to a user or a designated location of the second smart gateway.

In this case, the second smart gateway may request a refund of the cost corresponding to the energy not transmitted to the first smart gateway, or may request to transmit the remaining energy later.

Of course, the second smart gateway may cancel the transaction itself and provide the supplied energy to the user or designated location of the first smart gateway.
