Description

[0001] DEMAND RESPONSE SERVER [0002] TERMINAL AND CONTROL METHOD [

The present invention relates to a demand response control technique.

Demand response means controlling the power consumption of the load connected to the grid to maintain a balanced supply and demand of the grid. Generally, the power supply imbalance of the system is solved by controlling the generator. For example, when the power consumption increases, the operator increases the power generation amount of the generator to balance the power supply, and when the power consumption decreases, the operator decreases the operation of the generator, thereby balancing the power supply and demand do.

Demand response, on the other hand, is to control the load, not the generator, in the event of an imbalance in supply and demand, or in a situation where such an imbalance in supply and demand is anticipated. For example, the demand response is to balance the power supply and demand by reducing the power consumption of the load when the power consumption exceeds the power generation in the power supply of the system.

Among loads, there are loads that can be controlled by a provider (a server managed by a provider) that manages the system. These controllable loads can be immediately controlled in situations where demand response control is required. However, most of the load is not under the control of these operators, and there is a separate entity that manages the load. For example, in-home subordinates (eg, washing machines, TVs, lights, etc.) are not under the control of the operator who controls the system, but are under the control of residents residing in the home. For these loads, the demand response command is sent to the management subject of the load rather than the direct control of the load, and the indirect demand response that allows the management subject to control such as power consumption reduction for the load Control can be applied.

However, the following problems arise in the indirect demand reaction control.

First, there is no practical way to force a demand response at a particular point in time, which makes it difficult for a business operator to predict the amount of available demand response resources at a particular point in time.

In addition, it will indiscriminately provide demand response commands to the management subjects that are not practically able to participate, thereby raising the participants' fatigue to the demand response service and lowering their participation.

In this context, the object of the present invention is, in one aspect, to provide a technique for transmitting a demand response command only to a demand response participant capable of controlling the load.

In another aspect, an object of the present invention is to provide a technique for identifying controllable loads and predicting a demand-responsive resource amount.

In order to achieve the above object, in one aspect, the present invention provides a server for grasping a power supply state of a system and transmitting a demand reaction command in accordance with the power supply state, the load position information A storage unit for storing load information including load information including load information of the demand reaction participants and storing the load information in association with a load to be managed, a receiving unit for receiving terminal position information from the terminals of each demand reaction participants, A controller for comparing the load position information and the terminal position information with each other and determining terminals located within a load management range from a load position of the associated load as command transmitting terminals and a transmitter for transmitting the demand reaction commands only to the command transmitting terminals Provides a demand response server that includes.

According to another aspect of the present invention, there is provided a control method of a server for grasping a power supply / demand state of a system and transmitting a demand reaction command in accordance with the power supply / demand state, the method comprising: Storing the terminal information of the demand reaction participants managing each load in association with the managed load, receiving the terminal position information from the terminal of each demand response participant, A control step of comparing the terminal location information and determining the terminals located within the load management range from the load location of the associated load as command transmission terminals; and a transmission step of transmitting the demand response command only to the command transmission terminals Provides a demand response control method.

According to another aspect of the present invention, there is provided a terminal for receiving the demand reaction command from a demand reaction server that grasps the power supply and demand state of the system and transmits a demand reaction command in accordance with the power supply state, And transmits the terminal location information including the terminal location to the demand response server through wireless communication resources with at least one wireless communication base station among the wireless communication base stations And

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference numerals even though they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In describing the components of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected to or connected to the other component, It should be understood that an element may be "connected,""coupled," or "connected."

1 is a block diagram of a demand reaction system according to an embodiment of the present invention.

Referring to FIG. 1, loads are connected to the system 150 through contacts. The contact may be a node through which loads are connected to the system 150, and N (where N is a natural number of 2 or more) contacts may be connected to the system 150.

The contact may include a meter. The meter may be referred to as a meter, but is not limited thereto. The contact can use this meter to measure the amount of power passing through the contact. The measured amount of electric power can be transmitted to another device so that the other device can grasp the amount of power flow at the contact point.

The meter may measure the amount of power flowing in and out of one line, but it may also measure the amount of power that is branched out through each sub-meter while including a plurality of sub-meters. For example, when three loads are connected to a contact, the meter includes three sub-meters, and each sub-meter can measure the power consumption of each of the three loads.

The contact may have more than one load connected. 1, one load is connected to one contact for convenience of explanation, but the present invention is not limited thereto. Unlike the case shown in FIG. 1, a plurality of loads may be connected to one contact .

The contact may be connected to one or more demand response loads (DR (demand response) loads, hereinafter referred to as DR loads). The DR load refers to the load involved in the demand response service. This DR load may be registered in the demand response server 110 that manages the demand response in the system, but is not limited to this, and may be determined by the individual judgment of the demand response participant managing the DR load without being registered in the demand response server You may or may not participate in a response service.

1, the DR load 1 130a is connected to the contact 1 140a, the DR load 2 130b is connected to the contact 2 140b, and the DR load n 130n is connected to the contact n 140n have. Hereinafter, embodiments will be described by taking the contact 1 (140a), the DR load 1 (130a), the contact 2 (140b), and the DR load 2 (130b) as an example. However, as shown in FIG. 1, N DR loads may be connected to the system through contacts. Thus, the examples for DR load 1 130a and DR load 2 130b can be extended to N (N is a natural number greater than 2) DR loads.

Each DR load can be controlled by demand response participants. Demand response Participant means a person who has joined the demand response service provided by the provider who manages the system. The information on the demand reaction participant can be registered in the demand reaction server 110 that manages the demand response in the system. The fact that the DR load can be controlled by the demand response participant means that the power consumption of the DR load can be changed consciously by the control of the demand response participant. For example, if the demand response participant intercepts the power input to the DR load, the power consumption of the corresponding DR load changes to 0W.

In the above, we focused on the power flow in the demand reaction system. Next, we focus on the flow of information in the demand reaction system.

And a demand reaction server 110 (hereinafter referred to as "server") that manages the demand response of the system is interlocked with the system. The server 110 obtains at least one information formed in the system. The at least one piece of information may be, for example, a power flow amount of a contact measured at each contact point or load usage information for each DR load. As another example, the server 110 may acquire information on the power supply / demand status of the system. This power supply state can be calculated by measuring or estimating the tidal current of the system, or indirectly through other state variables (e.g., voltage or frequency) of the system. (110) can grasp the power supply / demand state of the system.

The server 110 can grasp the state of power supply and demand of the system and transmit a demand reaction command to the demand reaction terminals 120a, 120b and 120m (hereinafter, referred to as 'terminals') according to the state of power supply and demand. Here, the demand reaction terminal may be M (M is a natural number of 2 or more). Hereinafter, for convenience of description, the two terminals 120a and 120b will be mainly described. However, since the terminal can be extended to M, the examples applied to the two terminals 120a and 120b described above can be extended to M terminals.

The server 110 may transmit a demand response command to the terminals 120a and 120b through the wireless communication base station 160. [ At this time, the first terminal 120a is a terminal of the demand response participant capable of controlling the DR load 1 130a to the terminal connected to the DR load 1 130a. The second terminal 120b is a terminal of the demand reaction participant capable of controlling the DR load 2 130b to the terminal associated with the DR load 2 130b. As will be described later, the server 110 can send a demand response command to the terminals 120a and 120b, but does not always transmit demand response commands to all the terminals 120a and 120b.

Referring to FIG. 1, a first load management range 170a is set from the DR load 1 130a, and the server 110 as a first terminal 120a located in the first load management range 170a Demand response command can be transmitted. However, the server 110 may not transmit the demand response command to the second terminal 120b located outside the second load management range 170b from the DR load 2 130b.

2 is a diagram illustrating a terminal for transmitting a demand response command by a demand response server according to an embodiment.

Referring to FIG. 2, the server 110 transmits a demand response command only to the first terminal 120a and does not transmit a demand response command to the second terminal 120b.

More specifically, the first load management range 170a is set around the DR load 1 130a, the second load management range 170b is set around the DR load 2 130b, . Here, the first load management range 170a and the second load management range 170b may be the same value, but they may be different values.

The first terminal 120a is located within the first load management range 170a of the DR load 1 130a. On the other hand, the second terminal 120b is located outside the second load management range 170b of the DR load 2 130b. On the other hand, the server 110 can transmit the demand reaction command only to the terminals located within the load management range of the load.

The load management range can be unilaterally set by the server 110 to indicate a range in which the load can be controlled with respect to the demand reaction command. The load management range can be set unilaterally according to the characteristic of the individual load, Value may be set.

2, the terminals 120a and 120b transmit their location information to the server 110 through the wireless communication base station 160, and the server 110 transmits location information of the terminals 120a and 120b It determines whether each terminal is within the load management range and transmits a demand response command only to the terminal 120a within the load management range.

3 is an internal block diagram of a demand response server according to an embodiment.

The server 110 includes a storage unit 310 for storing information for performing demand reaction control, a receiving unit 320 for receiving information from peripheral devices, a control unit 330 for performing a demand reaction control, A transmitting unit 340 for transmitting information, and the like.

As a concrete example, the server 110 stores load information including load position information of loads participating in a demand reaction, and stores the terminal information of the demand reaction participants managing each load in association with a load to be managed A receiving unit 320 for receiving terminal location information from the terminal of each demand reaction participant, load position information and terminal location information, comparing the terminal location information with the load location of the associated load, A control unit 330 for determining the command transmission terminals, and a transmission unit 340 for transmitting a demand response command only to the command transmission terminals.

The server 110 receives terminal location information from the terminal. At this time, the terminal can estimate the terminal location by measuring a signal received from the wireless communication base stations.

4 is a diagram for explaining a method of estimating a terminal location by a demand response terminal according to an embodiment.

The terminal 120 communicates with a wireless communication base station (160a, 160b, and 160c in FIG. 4) that forms the corresponding cell coverage within the cell coverage (410a, 410b, and 410c in FIG. Referring to FIG. 4, a UE 120 exchanges signals with a corresponding radio communication base station 160a within a cell coverage 410a of a radio communication base station 160a. At this time, the terminal 120 receives the ID value of the wireless communication base station 160a from the wireless communication base station 160a to which the signal is transmitted. This ID value is a unique value for distinguishing the wireless communication base station. Based on this ID value, the terminal 120 determines that it is located in the cell coverage of the wireless communication base station having the corresponding ID value.

The terminal 120 can transmit the ID of the communicating radio base station to the server 110 as the terminal location information. At this time, the server 110 can determine the terminal location by checking the location information of the wireless communication base station having the corresponding ID.

As another method of confirming the terminal location, the terminal 120 can estimate a terminal location by measuring signals received from at least three wireless communication base stations. Referring to FIG. 4, the terminal 120 is receiving signals from three wireless communication base stations 160a, 160b, and 160c. At this time, the terminal 120 can estimate the distance to each wireless communication base station by measuring the intensity of the signal received from each of the wireless communication base stations 160a, 160b, and 160c or the arrival time of the signal. For example, the strength of a signal may be reduced in inverse proportion to the square of the distance and the cube according to the communication method. Using this principle, the distance to the wireless communication base station transmitting the signal through the strength of the measured signal is estimated can do. Also, when transmitting signals synchronized in time with two different wireless communication base stations, the relative distance difference between the two wireless communication base stations can be measured through the difference in arrival time of the signals.

In this way, by measuring the signal received from at least three or more radio communication base stations, calculating the distance from each radio communication base station to the terminal, and assigning this distance to the triangulation method, the terminal 120 can estimate the position of the terminal have.

The terminal 120 can estimate the terminal position using a global positioning system (GPS) signal.

The three methods that the terminal 120 may use to estimate the terminal location are complementary rather than competitive. The terminal 120 can estimate the terminal position using one of three methods as necessary. However, in some cases, the terminal 120 can improve the accuracy of the estimated value of the terminal location by using two or more different methods together have.

The storage unit 310 may store various information for performing demand reaction control.

5 is a block diagram of an example of a demand response participant database stored in a demand response server according to an embodiment.

Referring to FIG. 5, the storage unit 310 may store a participant information table 510. In the participant information table 510, information on demand reaction participants can be stored. For example, personal information such as the participant's name, address, etc. can be stored. In addition, the participant information table 510 may store information on the participant's terminal. The information about the terminal of the participant is used by the server 110 to transmit a demand response command.

In the participant information table 510, the terminal information of the participant can be stored in association with the load information managed by the participant. Referring to FIG. 4, a communication ID 512 is stored as terminal information of a participant. The communication ID 512 is an ID that can transmit and receive information using the wireless communication system. A typical telephone number may correspond to such a communication ID.

The participant terminal information stored in the participant information table 510 is stored in association with the load information 514. The load information 514 may further include the lower information through a separate load information table 520. [

The load information table 520 may include total load information 522 that can be used by the load. The total load amount information 522 is a value corresponding to the rated power, and is an amount of electric power to be used when the load is operated at rated speed.

The load information table 520 may include load information 524 for which the load is reducible in a demand response. The control unit 330 can estimate the amount of demand-responsive resource by using the demand-response reducible load amount information 524 for each load. For example, the control unit 330 compares the load position information and the terminal position information and determines the terminals located within the load management range from the load position as the command transmission terminal. At this time, the controller 330 predicts the demand-responsive resource amount using the demand-responsive reducible load information 524 stored in the command transmission terminals.

The load information table 520 may include information on the time when the load can participate in the demand reaction (available time information, 526). Depending on the type of behavior of the demand response participants, there may be times when the load can not be controlled. For example, in a night time zone corresponding to bedtime, a factory operation time zone, or a time zone in which a participant does not want to be disturbed, a demand response participant may not participate in a demand response even if it receives a demand response command. The control unit 330 may confirm the participation availability time information 526 for the load to the terminal associated with the load and may not transmit the demand response command at a time when it can not participate in the demand response service.

The load information table 520 stores load position information 528. [ The load position information may further include information on the load management range as well as information on the geographical position of the load. This range of load management can vary depending on the characteristics of the load. For example, a load included in a building can be controlled anywhere in the building, so the load management range is wide. On the other hand, the loads included in individual houses can be controlled only within the houses, so the load management range is narrow.

6 is a diagram for explaining that the load management range is controlled differently for two loads.

Referring to FIG. 6, the distances between the loads 130a and 130b and the terminals 120a and 120b are substantially the same. The first load management range 170a of the DR load 1 130a is larger than the second load management range 170b of the DR load 2 130b. Accordingly, the first terminal 120a is located within the first load management range 170a, and the second terminal 120b is located outside the second load management range 170b. Then, the control unit 330 transmits the demand reaction command only to the first terminal 120a located within the load management range. In this way, the control unit 330 can control the load management range of the loads differently.

The load management range can be set differently depending on the characteristics of the load, but it can be set through repeated change control in a situation where the characteristics of the load are not known.

7 is a diagram showing that the load management range is changed and controlled.

The control unit 330 may send the demand reaction command and obtain the load usage information through the meter of the load 130 associated with the terminal 120 that has been sent. When the load usage information is obtained from the meter, the controller 330 can determine whether the load associated with the command transmission terminals that transmitted the demand response command has participated in the demand response.

The control unit 330 can control the load management range 170 of the load 130 in which the demand reaction participation is not recognized to be less. Also, in the same context, the control unit 330 can control the load control range of the load in which the demand reaction participation is determined to be participatory.

The control unit 330 can perform the load management range change control through the statistics on the demand reaction participation. Through statistical processing of at least two demand responses, it is possible to grasp the relationship of participation of demand response according to the terminal location and to change the load management range according to the relationship diagram.

8 is a flowchart illustrating a method of controlling a demand response server according to an embodiment of the present invention.

The control method described with reference to FIG. 8 can be all performed by the server 110 described with reference to FIG. 1 to FIG. In addition, the description of the embodiment of the server 110 can also constitute another embodiment in combination with the embodiments described below in a control method.

Referring to FIG. 8, the server 110 grasps the power supply / demand status of the system and transmits a demand response command according to the power supply status.

Here, the server 110 stores load information including load position information of loads participating in a demand reaction, and stores the terminal information of the demand reaction participants managing each load in association with a load to be managed (S810 ). At this time, the stored load information may further include reducible load information in the load demand reaction.

The server 110 receives the terminal location information from the terminal of each demand response participant (S820).

The server 110 compares the load location information and the terminal location information, determines the terminals located within the load management range from the load location of the associated load as command transmission terminals (S820), and requests only those command transmission terminals A reaction command is transmitted (S840).

On the other hand, in step S820, the server 110 can estimate the demand-responsive resource amount using the reducible load information of the load associated with the command transmission terminals, and control load management ranges of at least two loads differently . In step S820, the server 110 determines whether or not the load demand associated with the command transmitting terminals is participated in the demand response through the load usage information obtained from the meter associated with each load, The load control range of the load detected as the non-attendance can be controlled to be small, or the load control range of the load detected by the participation of the demand reaction can be controlled to be large.

9 is an internal block diagram of a demand response terminal according to an embodiment.

The terminal 120 shown in FIG. 9 checks the power supply / demand status of the system to the first terminal 120a or the second terminal 120b shown in FIG. 1 and transmits a demand response command And receives a demand reaction command from the server 110.

9, a terminal 120 includes a controller 910 for measuring a signal received from at least three wireless communication base stations and estimating the terminal position, terminal position information including a terminal location, at least one of the wireless communication base stations A transmitter 920 for transmitting the request to the demand reaction server through wireless communication resources with one wireless communication base station and a receiver 930 for receiving a demand response command from the demand response server when the load is within the load management range from the position of the associated load, And the like.

On the other hand, the controller 910 can estimate the terminal position using the triangulation.

10 is a flowchart illustrating a method of controlling a demand response terminal according to an embodiment of the present invention.

The terminal performing the control method of FIG. 10 is a terminal 120 shown in FIG. 9, and as described above, as the first terminal 120a or the second terminal 120b shown in FIG. 1, And receives a demand response command from the demand response server 110 that transmits a demand response command in accordance with the power supply state.

10, the terminal 120 measures a signal received from at least three wireless communication base stations to estimate the terminal position (S1010), and transmits terminal position information including the terminal position to at least one of the wireless communication base stations To the demand response server through wireless communication resources with the wireless communication base station in step S1020. Then, when the terminal 120 is within the load management range from the position of the associated load, it receives a demand reaction command from the demand response server (S1030).

On the other hand, in step S1010, the terminal 120 can estimate the terminal position using triangulation.

Meanwhile, as a further embodiment, the server 110 transmits a demand response command to the participant (terminal) and confirms participation of the participant in the demand reaction, and sets the load management range of the participant according to the demand response participation statistics )). ≪ / RTI > For example, if a participant A continues to participate in a demand response even when the distance from the load is 20 m, the load management range of A may be set to 20 m or more. On the other hand, if B participant does not participate in the demand reaction when it is located more than 10m away from the load, the load management range of B can be set within 10m.

In connection with this additional embodiment, the server 110 may initially execute a process of sending a demand response command to all participants and confirming participation of the participants. Then, the load management range of the participant can be determined, and the above-described embodiments can be implemented accordingly.

In some cases, the load management range may be set to zero. This means that the participant does not participate in virtually any command.

As another additional embodiment, it is possible to additionally add the item "participation degree" in addition to the load management scope to transmit the demand response command differently according to the degree of participation. If the load management range is changed from time to time according to the degree of participation, the control may become unstable. The server 110 manages the participation degree as a separate item without changing the load management range from time to time according to the participation degree, For low participants, it is possible to lower the fatigue of participants by reducing the frequency of sending demand response commands.
