Here, background art relating to the present disclosure is provided, and they are not necessarily meant to be known arts.

The power supplier operates a demand response (DR) service to drive energy savings for the participant (consumer) when the power reaches a peak. According to this service, the provider notifies the peak of the electric power amount, and the participant receiving the notice message reduces the electric power consumption. The amount of power consumed here is compensated by the supplier in a certain form to the participants. Specifically, for example, the power exchange issues a DR signal (reduction command) at a time when a peak of a power peak in summer or winter is anticipated or peaked. Then, the providers participating in the DR business transmit the power reduction message according to the DR signal to the customers managed by themselves. According to this message, consumers who save power will be compensated for future gains from power savings. The supplier's system is operated in this way to manage the power, but the power savings in such a system is such that the information is not properly communicated to the individual in the customer and how much it voluntarily moves. have.

Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings.

Figure 2 illustrates a power management system in accordance with the present disclosure. The power supplier 200 has a power grid for supplying power to the consumer. It supplies electricity to the consumer through this grid. The power supplier 200 has a power management server 201 for monitoring the power situation of such a power grid.

A plurality of subgroups may be formed in the power grid to receive power step by step. Usually there is a provider designated by the power supplier 200, there may be a customer who is subscribed to the provider, and the end user group 202, 203, e.g., general households, is ultimately supplied with electricity.

In FIG. 2, a method of managing the end user groups 202 and 203 will be described with reference to FIG. A power management system for managing power in a power grid has a power management server (201) for collecting and processing data related to power. The end user groups 202 and 203 of the system include an access point 210 (AP, Access Point) having an address and an ID that can be connected to the power management server 201 by the Internet or its own infrastructure, A power measurement device 220 connected to the power management server 210 and having an ID, and a user terminal 240 communicable with the power management server 201.

The power measurement device 220 installed in the end user groups 202 and 203 can communicate with the Internet or the like and can have a wireless communication function. The power measuring device 220 may be a smart meter that is capable of communicating with an electric meter currently used in the home. May transmit power usage information of the end user group 202, 203, or may optionally receive information from the supplier 200 to process the requested items.

The power measuring device 220 is installed in the power network and stores the ID of the power measuring device 220 and the ID and MAC address of the access point 210 used by the power measuring device 220 as power And registers it in the management server 201. This may be due to the user's program installation or random registration, or may be a plug and play function that automatically sends information at the time of installation.

When the power measurement device 220 is installed, the power management server 201 can know the amount of power usage in the end user groups 202 and 203 and analyze and collect data. In addition, the power management server 201 can specify the location of the power measurement device 220 according to the information of the access point 210 specified at the time of installation of the power measurement device 220.

The access point 210 has its own Media Access Control (MAC) address and ID. With this, the access point 210 can specify its location on the communication network. In addition, the location of the power measurement device 220 coupled to the access point 210 may additionally be specified. The communication network may be based on the network infrastructure of the power network operator, or may be based on the Internet. There is no restriction on wired and wireless. The wireless access point 210 allows wireless devices to connect to a wired network using industry standards such as WiFi, BlueTooth, and Zigbee. The wireless access point 210 is generally connected to a router that relays a wired network and can relay data between a wireless device such as a computer, a printer, or a smart phone, and a wired device on the network.

Also, the access point 210 may have a password set by the user. In this case, only the authorized user having the password can obtain the access point 210 information and send the event result information 252 to the power management server 201.

The user terminal 240 may be any communication device such as an arbitrary terminal installed on the supplier 200 side, a smart phone used by a user, a pad type computer, a notebook computer, or the like. The user terminal 240 is provided with a location based application (App), which is a program for communicating with the power management server 201. The app can receive the event message 251 sent by the power management server 201 and show it to the user. The user will control or reduce power usage based on the content of messages received through this app. The user who participated in the event transmits the event result information 252 to the power management server 201. The event result information 252 includes adjustment information according to a user's event request and the ID and address of the access point 210 used by the power measurement device 220 of the participating end user groups 202 and 203. Accordingly, the user participating in the event can send the position of the participant at the time of the participation to the power management server 201 using the access point information, and the power management server 201 calculates the degree of the power amount adjusted or reduced by the event Allow the user to compensate.

The location based participating app can allow the user to confirm and directly input the address and ID information of the access point 210 to which the power measuring device 220 is connected. Alternatively, the access point 210 may be configured to automatically determine whether the power measurement device 220 is connected to the access point 210.

The user directly turns off the home appliance 230 or adjusts the power used to adjust the power. In Figure 3, an additional method by which the user adjusts the power is described. The home appliances 230 installed in the end user group 202, 203 may have an actuator 260 that enables control thereof. The actuator 260 is connected to a power source unit or a power source management unit of the home appliance 230 so that the user can adjust the power used by the home appliance 230 through the actuator 260. The actuator 260 may enable the ID to be automatically registered in the power management server 201. [ Plug and play installation may be possible in the same manner as the power measuring device 220. However, if necessary, the ID of the actuator 260 to be used by the user himself may be directly registered in the power management server 201. [ The actuator 260 makes it easier for the user to control the household appliance 230. The location based participating app has a function to control the actuator 260 so that it can control the electricity usage amount of the home appliance 230 even when the user is outside the area of the end user group 202 or 203 . The number of the home appliances 230 controlled by the actuator may be one or more.

In FIGS. 4 and 5, the configuration and data exchange of the power management server 201 for managing the amount of used power of each of the end user groups 202 and 203 will be described. First, the power management server 201 receives and stores the address and ID of the access point 230 and the ID of the power measuring device 220 connected from the power measuring device 220. The power management server 201 transmits an event message 251 to each user terminal 240 when a power management event (e.g. power reduction according to the power peak) is required. Users holding the user terminal 240 may perform actions necessary for power reduction according to an event. As a concrete example, when the power peak enters the peak state due to over-use of the cooler in summer, the power management server 201 transmits an event message 251 related to power reduction (DR) to users. Users perform an event at their location and notify the power management server 201 of the result. The contents of the event result may be such that the power of the specific home appliance 230 is cut off or the amount of power used is reduced. The power management server 201 generates the compensation contents to the personnel who participated in the performance, using the personnel who participated in the event and the measurement result from the power measuring device 220. Compensation may be a point or cash amount designated by the system operator. The power management server 201 uses the data of the access point 210 sent by the user to determine whether or not the data matches the data of the access point 210 of the registered power measurement apparatus 220 and then make compensation.

The power management server 201 includes a power measurement device management unit 301 that receives information of the power measurement device 220, an event transmission unit 310 that transmits a power management event message 251 to the user terminal 240, And an information receiving unit 320 for receiving the user control information and the access point 210 information 252 from the control unit 240. In addition, the power management server 201 has a compensation information generating unit 330 for generating predetermined user compensation information according to an event result. All the information generated and exchanged here is stored in the data storage unit 340.

 The compensation information generating unit 330 of the power management server 201 uses the data transmitted from the registered power measuring apparatus 220 to calculate the basic usage power amount CBL of the end user groups 202 and 203, In the data storage unit 340. [ When an event related to the power reduction is generated by the power management server 201, it is compared with the basic use amount of power (CBL) value to determine the amount of power adjusted by the event.

FIG. 6 illustrates a method in which the user terminal 240 confirms the power measurement device 220 through a location based participating application. The user terminal 240 connects to the connectable access point 210 to determine if the power measuring device 220 is connected together. Then, the user can confirm whether the power measurement device 220 connected to the area where the event is performed is correct, and send the information of the access point 210 automatically confirmed at the time of sending the event result.

The location-based program of the terminal can be operated in the following order.

P1) Confirm the address and ID of the access point 210 to which the terminal is connected

P2) whether or not the power measuring device 220 connected to the access point exists and the ID of the power measuring device 220

P3) receiving an event message 251 of the power management server 201

P4) Display event message on screen

P5) Receive user's event result (control information)

P6) The control information is transmitted to the power management server 201, the address of the access point 210 to which the terminal is connected, the ID information sending unit 252,

7 is a diagram showing another embodiment of this disclosure. One power measuring device 220 can measure only the total power consumption connected to the household appliances 230 divided into the plurality of spaces A, B, C, and D. The user (a) of the separately divided space A reported adjustment information info1 for power reduction, but it is necessary to verify the authenticity of this report. To this end, the power management system has a sensing device 710 that measures changes in the spatial environment, such as a thermometer or an illumination sensor, that is accessible to the access point 210 in the space A. The sensing device 710 may select the ID of the device itself, the address and ID of the connected access point 210 and the ID information of the power measuring device 220 to which the home appliances 230 in the same space are connected, To the power management server 201, and the power management server 201 can store them. In addition, the measurement information can be transmitted to the power management server 201 through the access point 210. In this system configuration, when the user (a) terminal 740 sends home appliance 230 control information according to the event message 251 (for example, when the temperature of the air conditioner is adjusted or the brightness of the light is lowered The power management server 201 can actually verify whether the environmental change such as temperature or illumination has occurred by using the measurement information change data of the sensing device 710, (a) to make appropriate compensation accordingly. The related information will also be transmitted to the compensation information generating unit 330. [

According to the system and method of this disclosure, it is possible to build a system of effective demand response services that can compensate users who actually participate in power control and reduction, thereby motivating individual users. In other words, it is compensated for the amount of power saved in one building or factory unit, but in this system, it is possible to control the power in smaller units by floor and furniture. Within each area covered by each access point 210, it is possible to compensate for the individual who actually participated in the event.
