4 is a flowchart illustrating a method of trading surplus power according to an embodiment of the present invention.

First, the communication unit 120 of the energy transaction apparatus 100 may receive a surplus power brokerage transaction request from the seller terminal 200 (S310). Here, the surplus power may be, for example, surplus power of a renewable energy power generation facility or surplus battery power of an electric vehicle.

Upon receiving the request for brokerage transaction of surplus power from the seller terminal 200 ( S310 ), the matching unit 140 of the energy trading device 100 may match the seller and the buyer of the surplus power ( S320 ). The seller-buyer matching method by the matching unit 140 may be various, such as one-to-one, one-to-many, many-to-one, many-to-many, etc. in consideration of the amount of surplus power, the amount of power desired to be purchased, and the like.

Also, the matching unit 140 according to an embodiment of the present invention may preset various matching conditions for seller-buyer matching. For example, the matching unit 140 may match the seller and the buyer according to the order in which the sale or purchase of surplus power is requested, or provides an interface for the buyer to select the seller to the buyer terminal 300 and provides the buyer terminal In an intermediary method that can match the seller and the buyer selected by 300, or consume surplus power directly from the seller's electric power generation site, matching the seller and the buyer based on the seller's electric power generation site and the buyer's location information (e.g. For example, it is possible to first match the buyer closest to the seller's location).

When the seller-buyer matching is made by the matching unit 140 (S320) and the transaction of the surplus power is completed, the settlement unit 150 of the energy trading device 100 is configured between the seller terminal 200 and the buyer terminal 300. Settlement for the surplus power transaction may be performed, where the settlement may include payment of a purchase cost of the surplus power, addition/deduction of power usage according to credit sales, and the like.

In addition, in a manner in which the buyer directly consumes surplus power at the seller's power site, the payment cost per unit power of surplus power may be smaller than the payment cost per unit power provided by the electricity sales business operator, and therefore the surplus power seller Since a financial gain can be obtained for the surplus power for which no monetary compensation has been made, and the surplus power buyer can also consume power at a lower cost, when using the energy trading service according to the present invention, the surplus power This can be costly for both sellers and buyers of electricity.

In addition, the energy trading device 100 according to an additional embodiment of the present invention is configured to evaluate the quality (or grade) of surplus power in the surplus power brokerage transaction request received from the seller terminal 200 through the communication unit 120 . It may further include a quality evaluation unit (not shown). For example, in the quality evaluation department, voltage, current, frequency, power factor, active power, reactive power, apparent power, harmonics for each order, voltage harmonic distortion factor, current high frequency distortion factor, imbalance, transient phenomenon of the surplus power the seller wants to sell , flicker, etc. may be measured to evaluate the quality (or grade) of the surplus power.

Accordingly, the settlement unit 150 according to an additional embodiment of the present invention may differentially calculate the cost of using the surplus power based on the quality or grade of the surplus power evaluated by the quality evaluation unit.

As shown in FIG. 5A , the controller 110 may control the holder of the electric vehicle or the holder of the virtual currency mining machine to directly visit the power generation site of the seller A as a surplus power purchaser and consume the surplus power. In this case, since actual power consumption occurs at the power generation site of the surplus power seller, the buyer only needs to pay the seller the cost according to the amount of power consumed. not required

In this way, the surplus power brokerage transaction request received from the seller terminal 200 includes the amount of surplus power, the location of the power generation site, available time (eg, from 9 am to 6 pm), usage method, and usage. Notes, etc. may be additionally included.

For reference, virtual currency (or cryptocurrency) mining refers to the process of finding virtual currencies such as bitcoin, monero, ethereum, and litecoin, and is generally As such, a miner for mining such virtual currency can be implemented as a high-performance computer that is divided into mining software and mining hardware. Therefore, by moving the virtual currency miner directly to the power site of the surplus electricity seller, it is possible to perform virtual currency mining by consuming electricity at a lower cost.

Here, the amount of power consumed by the virtual currency miner per hour can be calculated based on the power consumption time by utilizing the almost constant point that the virtual currency miner consumes at the seller’s power generation site. Similarly, the electric vehicle’s charging mode (slow or slow Rapid), the power consumed per hour according to the supply voltage (220V or 380V) is also almost constant, so that the amount of power consumed by the electric vehicle at the seller's power generation site can be calculated based on the electric vehicle charging time. According to the amount of consumed power, the cost of using the surplus power between the seller and the buyer can be settled.

5B is a schematic diagram for explaining a virtual transaction method of surplus power according to the second embodiment of the present invention. In the surplus power transaction method according to the second embodiment of the present invention, the buyer purchases the seller's surplus power credit and offsets the fee without directly moving the buyer's equipment, vehicle, etc. to the seller's power generation site. Corresponds to the method (that is, the power virtual consumption method)

As shown in FIG. 5B , the surplus power buyer can purchase surplus power credit from the surplus power seller, and since the seller's power usage is added as much as the traded credit and the buyer's power usage is subtracted, the electricity sales company (for example, , Korea Electric Power, etc.) may be required, and accordingly, the settlement unit 150 of the energy transaction apparatus 100 according to the present invention cooperates with the electricity sales business server 500 to add power consumption according to the credit transaction. /can be subtracted.

Additionally, according to the third embodiment of the present invention, when the seller's surplus power can be stored in a movable form (eg, electric vehicle surplus battery power, etc.), the controller 110 controls the seller of the surplus power. It is possible to control the consumption of the surplus power by going to the place of the purchaser of the surplus power.

Additionally, according to the fourth embodiment of the present invention, the surplus power of the seller may be stored in a home energy storage device, for example, an ESS (Energy Storage System), and the ESS is the energy trading system 1000 according to the present invention.
