Description

Apparatus and method for real-time transaction management of demand response resource {APPARATUS AND METHOD OF TRADING MANAGEMENT FOR DEMAND RESPONSE RESOURCE REAL-TIME}

The present invention relates to an apparatus and method for real-time transaction management of demand response (DR) resources, and more particularly, to an apparatus and method for real-time transaction reduction of power reduction for preserving a specified reduction amount when a demand response request occurs. It is about.

In general, power grids are designed so that the supply and demand of power is consistent with each other. The index indicating this balance is frequency, and the stability of this frequency is directly related to the quality of electricity. At present, the demand for electricity in the operation of the grid is very difficult to adjust because it depends on the individual electricity use. Therefore, the power supply always follows the power demand in real time.

However, since power demand fluctuates over time, the amount of power supplied is always to meet the maximum demand. Up to 10% demand is virtually three out of 365 days a year, so many generators are waiting for the three days. This is uneconomical and inefficient, just as it maintains several separate highway facilities that are not used for one year for the third day of the Chuseok holiday.

In this regard, demand management techniques related to providing incentives by voluntary energy savings of consumers by demand response (DR) have emerged. More specifically, the demand response (DR) means that when the demand for electricity increases, the consumer responds to it, thereby reducing the power usage and receiving incentives for this.

On the other hand, if a DR request occurs, a DR request participant must achieve a specified reduction, or there is a penalty such as dropping a DR request.

However, in the case of small-scale consumers such as general households, the amount of reduction due to the changing behavioral patterns of consumers is mostly difficult, so it is difficult to achieve the designated reduction every time.

In the following description, the power reduction amount seller The customer to be classified will be referred to as the seller 10, and the customer to be classified as a power reduction buyer will be referred to as the buyer 20.

For example, the transaction management apparatus 100 analyzes the power consumption or the customer baseline load (CBL) of the customers 10 and 20 participating in the demand response (DR) request and analyzes each customer by the seller 10. Or it may be classified as a buyer (20).

Herein, the power consumption of the consumers 10 and 20 may be obtained from the smart meters provided in the respective customers 10 and 20. In addition, the customer reference load (CBL) may be defined as a value for estimating power consumption in a case where the demand response (DR) participant does not reduce power, for example, may be calculated as an average of monthly power usage.

The transaction management apparatus 100 may determine whether the consumers 10 and 20 can preserve the designated reduction amount by analyzing the change in the power usage of the customers 10 and 20 and the change in the customer reference load CBL. There will be.

The transaction management apparatus 100 may request the seller 10 and the buyer 20 for transaction information for selling or purchasing a power reduction amount, respectively.

In this case, the transaction information may include an amount of power reduction to be sold or purchased, and a time period.

The transaction management apparatus 100 may receive power reduction amount purchase information from the seller 10 and the buyer 20.

The transaction management apparatus 100 may share power reduction amount transaction information between the seller 10 and the buyer 20.

The buyer 20 may check the power reduction transaction information of the sellers 10 and bid on the required transaction information.

The seller 10 may check the power reduction transaction information of the bidders 10 and bid the power reduction transaction information of any one of the sellers 10 who bid.

The transaction management apparatus 100 may mediate such a bidding and a successful bidding step. At this time, the transaction management apparatus 100 may be connected to a separate financial server so that the payment step according to the transaction details between the seller 10 and the buyer 20 may be performed, or the seller may use a score earned according to the transaction details. The payment step between the 10 and the buyer 20 can be made.

The transaction management apparatus 100 may re-notify the demand response request by reflecting the transaction details when the power reduction transaction is completed. In other words, the demand reduction request can be re-announced by subtracting or reducing the traded amount to the designated reduction amount per customer.

On the other hand, the transaction management device 100 may monitor the results of the demand response (DR) participation of the seller 10 and the buyer 20, and calculate a transaction evaluation score according to the result.

For example, the transaction management apparatus 100 may monitor whether the seller 10 and the buyer 20 have achieved the designated reduction amount, and may assign a transaction evaluation score according to the result.

The transaction management apparatus 100 may reflect the transaction evaluation score in the later sale or purchase authorization.

As described above, the real-time transaction management apparatus 100 for demand response resource according to an embodiment of the present invention induces a surplus power reduction amount transaction between the demand response (DR) participants to preserve the designated reduction amount of each participant, thereby making a transaction subject. In addition to providing economic benefits, it also encourages active participation in demand response (DR), enabling efficient and stable grid operation.

Hereinafter, each component of the real time transaction management apparatus 100 for demand response resources according to an embodiment of the present invention shown in FIG. 1 will be described in detail.

The demand response request notification unit 110 may receive a request response (DR) request from the grid operator and deliver it to each customer.

The demand response request notification unit 110 may communicate with the grid operator management server to receive a demand response (DR) request. In this case, the demand response request notification unit 110 requests demand response (DR) including information such as demand response (DR) announcement, real-time power consumption, designated reduction amount by customer, and designated reduction amount by time period from the grid operator management server. Information can be received.

The demand response request notification unit 110 may transmit the request response (DR) request information to all the customers who have entered into the demand response (DR) participation contract. The demand response request notification unit 110 transmits the request response (DR) request information to the smart device installed in the customer, the mobile terminal of the consumer, etc. so that the power reduction policy can be enforced at each customer.

The demand response request notification unit 110 may revise the request response (DR) request information and notify each customer again when a power reduction amount transaction between the customers is made.

For example, when the demand reduction request notification unit 110 is a power reduction amount transaction between the customer, if the reduction in the amount of power reduction transaction included in the demand response (DR) request information is added or reduced to notify each customer can do.

The customer classification unit 130 may classify all customers who have entered into a demand response (DR) into a customer to sell power reduction amount and a customer to purchase power reduction amount.

The customer classification unit 130 may classify the customer as a power reduction amount seller or a power reduction amount purchaser by analyzing power consumption or customer reference load (CBL).

To this end, the customer classification unit 130 may collect the current power consumption of the customer by using a smart meter installed in the customer. The customer classification unit 130 may calculate the average power consumption by storing the data every time the power consumption of the customer is collected. In this case, the customer classification unit 130 may collect the power consumption of the customer for each time zone, calculate the average power usage for each time zone, and store the average power consumption.

In addition, the customer classification unit 130 may collect a customer reference load (CBL) assigned to the customer from the grid operator management server. The customer classification unit 130 may calculate the average customer reference load CBL by storing the data each time the customer reference load CBL is collected.

If the current power consumption of the customer is higher than the average power consumption corresponding to the current time zone, the customer classification unit 130 may classify the corresponding customer as a power reduction amount purchaser.

Alternatively, if the customer reference load CBL specified in the customer is lower than the average customer reference load CBL, the customer classification unit 130 may classify the corresponding customer as a power reduction buyer.

Alternatively, the customer classification unit 130 is any one of the condition that the current power consumption of the customer is higher than the average power usage for the current time zone, or the customer reference load (CBL) specified in the customer is lower than the average customer reference load (CBL). Even if the condition is satisfied, the customer can be classified as a buyer of power reduction.

The customer classification unit 130 may classify the customer as a power reduction amount seller when the current power usage of the customer is lower than the average power usage corresponding to the current time zone.

Alternatively, when the customer reference load CBL specified in the customer is higher than the average customer reference load CBL, the customer classification unit 130 may classify the corresponding customer as a power reduction amount seller.

Alternatively, the customer classification unit 130 satisfies all of the conditions that the current power consumption of the customer is lower than the average power usage for the current time zone, or the customer reference load (CBL) specified in the customer is higher than the average customer reference load (CBL). Only then can the customer be classified as a power-saving seller.

The transaction information acquisition unit 150 provides the power reduction amount sale or power reduction amount purchase authority to each customer according to the result of the power reduction amount seller or the power reduction amount buyer classification, and thus the power reduction amount and power reduction to be sold or purchased from each customer. Transaction information including a time zone can be received.

For example, the transaction information acquisition unit 150 may request and receive transaction information including an amount of power reduction to be sold to customers classified as a power reduction amount seller and a time period thereof.

The transaction information acquisition unit 150 may request and receive transaction information including an amount of power reduction to be purchased at a customer classified as a power reduction amount buyer and a time period thereof.

The transaction intermediary 170 may broker the transaction between customers by allowing the transaction information to be shared between the customers.

The transaction intermediary 170 may grant a bid or a bid right when sharing transaction information between customers.

For example, a customer classified as a reduction buyer can check the transaction information and bid on the required transaction information. The transaction intermediary unit 170 notifies the seller's transaction information to the seller corresponding to the transaction information that the buyer bids, so that the seller can win any one of a plurality of buyers who have bid on their transaction information. . When the bidding and auctioning step is completed, the transaction intermediary 170 may close the transaction by making payment for the transaction details as described above.

Here, the transaction broker 170 may limit the selling or purchasing authority of the customer according to the transaction evaluation score in the monitoring unit 190 to be described later. Alternatively, the transaction intermediary 170 may give priority to bidding or a successful bid according to the transaction evaluation score in the monitoring unit 190 to be described later. In this regard, a detailed description will be made later.

The monitoring unit 190 may monitor the result of the customer's participation in demand response (DR), and calculate a transaction evaluation score according to the result.

The monitoring unit 190 may monitor whether the customer participating in the transaction has achieved the designated reduction amount according to the demand response (DR) request.

The monitoring unit 190 may assign a score to the corresponding customer when the customer participating in the transaction achieves the designated reduction amount according to the demand response (DR) request. In this case, the monitoring unit 190 may assign a score to a difference between the customer who sold the power reduction amount and the customer who purchased the power reduction amount. For example, the monitoring unit 190, if the two consumers participating in the transaction achieves the specified reduction amount according to the demand response (DR) request, and give both the scores, but doubled to the customer who sold the power reduction amount Can be given.

In addition, the monitoring unit 190 may assign a score in proportion to the power reduction transaction volume. Alternatively, the monitoring unit 190 may assign a score in inverse proportion to the total number of power reduction transactions in the time period during which the power reduction transactions occur.

When the customer participating in the transaction fails to achieve the designated reduction amount according to the demand response (DR) request, the monitoring unit 190 may negatively process the score of the corresponding customer. In this case, the monitoring unit 190 may negatively score the difference between the customer who sold the power reduction amount and the customer who purchased the power reduction amount. For example, if two consumers participating in the transaction do not achieve the designated reduction amount according to the demand response (DR) request, the monitoring unit 190 recovers the scores to both the customers, but purchases the power reduction amount to 2 customers. The ship's score can be recovered.

Meanwhile, the transaction broker 170 may limit the selling or purchasing authority of the customer according to the transaction evaluation score for each customer.

For example, the transaction broker 170 may not share transaction information with the customer to limit the power reduction sale or power reduction purchase authority if the customer's transaction evaluation score is less than or equal to a preset reference score. Can be.

In addition, the transaction intermediary 170 may select and provide transaction information of a customer classified as a seller as a corresponding customer for bidding a customer classified as a buyer. In this case, when there is a plurality of transaction information of a customer classified as a seller, the transaction broker 170 may list and provide a transaction evaluation score of each customer.

Similarly, the transaction broker 170 may select and provide transaction information of the bidders who have bid on the purchase information of the customers classified as the sellers. In this case, when there are a plurality of transaction information of a customer classified as a buyer, the transaction broker 170 may list and provide a transaction evaluation score of each customer.

In addition, the transaction broker 170 may set a bid or a successful bid time according to the transaction evaluation score of the customer when sharing the transaction information between the customer.

For example, the transaction broker 170 may provide a longer selection time for bidding or bidding as the transaction evaluation score of the customer is higher.
