[ For example, the DR controller 50 can automatically adjust the set temperature of the air conditioner while maintaining the user's constant comfort using the temperature profile.

The DR controller 50 is connected to the user terminal 30 through a local area network. When receiving the DR execution command from the user terminal 30, the DR controller 50 automatically executes an internal operation control program to control the operation of the electronic device 60 .

FIG. 3 shows the internal structure of the DR management server according to the present invention.

3, the DR management server 10 includes a communication unit 11, a DR tendency leveling unit 12, a discomfort calculating unit 13, a database 14, a DR guide information generating unit 15, An output unit 16, a DR compensation unit 17, and the like.

The communication unit 11 receives the user data including the DR tendency data and the target budget from the user terminal 30 via the mobile communication network (data communication network) or the Internet, DR signal.

The DR tendency leveling unit 12 provides a questionnaire or a form for grasping the DR tendency of the user to the user terminal 30 through the communication unit 11 and based on the DR tendency data of the user received from the user terminal 30 Leveling the user's DR tendency.

The DR tendency leveling unit 12 levelizes the DR tendency of the user on the basis of the DR tendency data of the user collected in the beginning and then calculates the DR response received from the user terminal 30 and the DR response received from the smart meter 40 It is possible to continuously update the DR tendency level of the initially set user.

The discomfort calculator 13 calculates an inconvenience or an inconvenience index that indicates the degree of inconvenience of the user as a numerical value. The discomfort and discomfort index values can be calculated on the basis of demand reduction demand, DR propensity level, and environmental information (outside temperature, humidity, weather, etc.).

The database 14 stores various DR-related data such as DR subscriber information, DR tendency level, and electricity use target budget.

The DR guide information generation unit 15 generates DR guide information based on the user's DR tendency, target budget and inconvenience. The DR guide information may include various types of messages such as a DR mandatory message including a DR automatic execution function, a general DR mandatory message, a DR mandatory message, and a DR recommendation message.

The DR compensating unit 17 compensates for the demand that has executed the DR in response to the DR signal. When the communication unit 11 receives the power consumption amount from the smart meter 40 of the demander and delivers the power consumption amount to the DR compensation unit 17, the DR compensation unit 17 compares the power consumption of the smart meter and the DR incentive, You can calculate the compensation amount.

4 is a flowchart illustrating a procedure for providing a demand response guide according to the present invention. Each step of FIG. 4 is performed within the DR management server.

Referring to FIG. 4, the DR tendency leveling step S10 determines the DR tendency level of each user by leveling the DR tendency of the user based on the DR tendency data of the user received from the user who responded to the questionnaire or the form.

The DR propensity level can be classified, for example, from level 1 to level 10 according to the DR policy. As you move to Level 1, you tend to be reluctant to DR, and as you move to Level 10, you tend to be more aggressive toward DR. In other words, if the level value is small, the participant tends to be reluctant to participate in the DR. If the level value is large, the tendency to actively participate in the DR even if the inconvenience is incurred.

The user budget setting step S20 stores the weekly, monthly or quarterly electricity use target budget input from the user in the database. For example, the user may enter the target tariff of 40,000 won in September or input the target amount of power of 280 KWh through the user terminal 30 of his or her smart phone or computer.

The inconvenience calculation step S30 calculates the inconvenience of the user according to the DR performance in consideration of the demand reduction demand, the DR propensity level of the user, and the environment information.

The discomfort value increases as the demand for demand reduction is larger, the outside temperature or humidity is higher, and the DR tendency level is lower. The discomfort function can be defined by Equation (1) as follows.

[Equation 1]

(D _i , T, L _i ) = a / L _i (D _i ) ² + bT

Here, Ψ is a discomfort function and has D _i , T, and L _i as variables. D _i is the demand reduction requirement assigned to user i, T is the outside temperature, L _i is the DR propensity level of user i, and a and b are arbitrary constants.

The DR guide information generation step S40 generates DR guide information based on the DR propensity level of the user, the electricity use target budget, and the inconvenience. A specific method of generating DR guide information will be described later with reference to FIG.

The DR signal output step S50 generates a DR signal for DR event notification using the DR guide information. The DR signal is transmitted to the user terminal through the communication network. The DR signal includes information such as a DR incentive, a demand reduction demand, a DR period, and the like, in addition to the DR guide information composed of a customized DR guide message.

FIG. 5 illustrates a process of generating DR guide information according to the present invention.

Referring to FIG. 5, first, the probability of exceeding the budget is determined based on the energy use history of the demand consumer (the power consumer) and the target budget (S100).

For example, when the DR event notification time is 2:00 pm on September 24, 2017, the usage is predicted from September 25 to September 30. The power consumption during the remaining days of September can be estimated by using the parameters such as the monthly usage and trend, the usage amount and the trend of the previous year.

The predicted power usage can be represented as a probability distribution, and if there is a power usage showing a probability of more than a predetermined value and the power usage exceeds the target budget, it can be judged that the possibility of exceeding the budget is great.

If the possibility of exceeding the user's target budget is high as a result of the power consumption prediction, a DR force message including the DR automatic execution function is generated irrespective of the DR tendency level or inconvenience of the user.

A DR force message with DR autorun must be entered into the DR for the user. DR will participate in the DR regardless of whether or not the user intends to participate ', and a DR execution command is automatically generated at the user terminal.

On the other hand, if the possibility of exceeding the target budget of the user as a result of the power usage prediction is small, the DR propensity level of the consumer (user) is determined (S102).

If it is determined that the DR tendency level is high as a result of the DR tendency level determination, it is determined whether the discomfort value (level) is high or low (S104).

If the inconvenience value is less than a certain value and the inconvenience is not high, a DR force message without a DR auto run function is generated.

A DR force message without DR autorun must be entered into DR for the user. DR Please press the acceptance button ".

On the other hand, if it is confirmed that the discomfort is higher than a predetermined value and the discomfort is high, a DR anti-mandatory message is generated.

The DR anti-mandatory message displays a message encouraging the user to participate in the DR. E.g. Please join 'DR' to DR user. You can display the message 'Please enjoy the benefits by clicking the DR acceptance button'.

If it is determined that the DR tendency level is low as a result of the DR tendency level determination, it is determined whether the discomfort value (level) is high or low (S106)

If the inconvenience value is less than a certain value and the inconvenience is not high, a DR anti-mandatory message is generated as in the state where the DR propensity level is high and the inconvenience value is high.

However, if it is confirmed that the discomfort is higher than a predetermined value and the discomfort is high, a DR invitation message is generated.

The DR invitation message displays a message to the user that does not actively encourage DR participation but solicit the user. For example, a DR invitation message can benefit from several benefits when you participate in DR. I hope you enjoy the benefits of participating in DR. "

FIG. 6 illustrates a process of processing a DR event in a user terminal according to the present invention.

6, the user terminal 30 checks whether a DR signal is received from the DR management server 10 (S200). When the DR signal is received, the user terminal 30 displays a DR guide message according to the DR guide information included in the DR signal (S202).

If it is determined in step S204 that the DR guide message is a DR force message having the DR auto-run function, the user terminal 30 generates a DR execute command in step S206. To the DR controller 50 connected by short-range communication or the like. Upon receiving the DR execution command, the DR controller 50 controls the operation of various electronic apparatuses according to an internal automatic control program.

If the DR guide message is a message other than the DR force message having the DR automatic execution function, the user terminal 30 displays a screen for selecting the DR participation or not, and confirms whether or not the user selects DR participation (S208 ).

When the user presses the DR participation acceptance button, the user terminal 30 generates a DR execution command and transmits it to the DR controller 50 (S206).

After the DR message is executed by the DR force message having the DR automatic execution function or the user's DR participation selection or the user terminal 30 does not execute the DR due to the DR participation rejection by the user, To the server 10 (S210).

The DR management server 10 updates the DR tendency level of the user based on the DR response signal received from the user terminal 30 and the power consumption amount received from the smart meter 40 of the demander.
