The server 300 having the power demand management function described below may be the same server (same configuration) as the labeling server 200 described in FIG. 7, and in this case, The server 200 may further include components. Alternatively, the server 300 may be a separate server from the labeling server 200 to perform a power demand management function (to be described later).

The power point energy measuring apparatus 100 described below will be described later with reference to FIG.

FIG. 1 shows a configuration diagram of a system having a power demand management function according to an embodiment of the present invention. FIG. 2 shows a flowchart of a power usage management method according to an embodiment of the present invention.

Although the labeling server 200 is not shown in FIG. 1, the labeling server 200 may function as the labeling server 200 (in the case of the same configuration) (If it is a separate configuration).

As shown in FIG. 1, a system 700 having a power demand management function includes a power entry point energy measuring apparatus 100, a subscriber's communication apparatus for requesting reduction of power usage, A communication device 400 for outputting guidance information on reduction in power consumption received from the server 300, at least one load device 500 used by a subscriber of the communication device 400, And a power supplier-related server 600 that transmits a request signal to the server 300 to reduce power usage.

In addition, according to an embodiment of the present invention, the system 700 having the power demand management function can additionally be connected to the sponsor server 610 and the carbon dioxide emission trading server 620.

Hereinafter, the operation of each component for carrying out the present invention will be described with reference to FIG.

The server 300 receives a request signal for power saving reduction from the power supply company related server 600 (S210).

Here, the power supply company related server 600 is a server managed by a power supply source (for example, KEPCO) or a power supply agency, and can perform overall operations regarding power supply and control.

Upon receipt of the request signal, the server 300 selects a subscriber to request the power saving using the subscriber information (S220).

Here, the server 300 may store the subscriber information and may update the subscriber information by reflecting the power usage state / pattern of the subscriber, or may update the subscriber information at the request of the subscriber.

The server 300 can select at least one subscriber who wants to request a reduction in power usage according to a predetermined criterion considering the power consumption, the estimated amount of power use, the probability distribution of savings due to compensation, and the like. Accordingly, the server 300 can select a subscriber that is predicted to be able to implement a power saving reduction request at a minimum cost. Alternatively, the server 300 may select a subscriber whose response to the power saving request is expected to be high.

Regarding selection of a subscriber, it will be described later in detail with reference to Fig.

The server 300 transmits guidance information on power saving reduction to the subscriber's communication device 400 selected in the selection step S220 (S230).

Here, the communication device 400 is a communication device of a subscriber registered in the server 300 for data communication with the server 300, and may be a mobile device such as a smart phone, a notebook computer, a tablet PC, A home appliance (e.g., a TV, a refrigerator, an air conditioner, etc.).

The server 300 monitors power usage by at least one load device of the subscriber selected in the selection step S220 (S240).

Accordingly, the server 300 can determine whether the actual amount of power used by the load device of the selected subscriber has decreased and the amount of saved power corresponding to the guide information transmitted in the transmission step S230 (S250).

Monitoring of the power usage can be understood with reference to the preceding description of data collection and extraction of power usage by the labeling server 200.

If it is determined in step S250 that the amount of power consumption is reduced to correspond to the guide information, the server 300 may provide a compensation corresponding to the reduction in power consumption (S260).

The server 300 can determine the compensation to be given to the subscriber in consideration of the actual amount of power saved corresponding to the guide information.

For example, the server 300 can give compensation in proportion to the amount of power saved. In addition, the server 300 can grant compensation for the power usage fee, and can award the compensation in the form of a point payment available for the discount of the power usage fee or the payment of the power usage fee.

Alternatively, the compensation according to an exemplary embodiment of the present invention may include cash, gifts, coupons, and the like provided by the sponsor server 610 other than the power supplier-related server. In this case, the server 300 can receive cash, gifts, coupons, and the like from the sponsor server 610 in an electronic form. Alternatively, the server 300 may accumulate electronic conversion points in the account of the sponsoring company so as to correspond to cash, gifts and coupons provided by the sponsoring company. The server 300 calculates the amount of power use savings corresponding to cash, gifts, coupons, or conversion points provided for each sponsorship company. In addition, the sponsor server 610 can acquire the carbon dioxide emission right from the carbon dioxide emission right transaction server 620 based on the calculated power use reduction amount. In this case, "based on power saving amount" means all cases where the amount of CO2 saving amount is converted based on the amount of power saving amount, and those skilled in the art can convert the amount of power saving amount to the amount of carbon dioxide savings using existing methods. Also, the carbon dioxide emission trading server 620 can confirm that the power reduction has been made by the power supplier-related server 600 or the server 300 corresponding to cash, gifts, coupons, etc. provided by the sponsor server 610 .

The server 300 may transmit the information on the compensation (hereinafter, compensation information) given in the granting step S260 to the communication device 400 of the subscriber (S270).

Therefore, the subscriber of the communication device 400 can confirm whether or not the actual power usage fee is discounted by the power saving action of the subscriber and the discount level. This can be effective in inducing subscribers to actively participate in power saving when power saving is required.

Fig. 3 shows a detailed configuration diagram of the server 300 having the power demand management function shown in Fig.

Referring to FIG. 3, the server 300 includes a storage unit 310 for storing subscriber information, a reception unit 321 for receiving a request signal for power saving reduction, A selection unit 331 for selecting a subscriber for requesting reduction in power consumption, a transmission unit 322 for transmitting the information on reduction of the power usage to the selected communication device of the subscriber, A monitoring unit 332 for monitoring the amount of power used, and a compensation management unit 333 for giving a predetermined compensation to the subscriber when the amount of power used by the load device decreases according to the guide information.

Here, the receiving unit 321 and the transmitting unit 322 may be implemented by respective communication modules or by one communication module 320. [ The selection unit 331, the monitoring unit 332 and the compensation management unit 333 may be realized by respective modules or may be implemented by one control module 330. [

The storage unit 310 may store subscriber information and may store information on power usage, in particular, per subscriber. For example, as subscriber information, it is possible to store information on power consumption by individual load devices or individual load devices, power usage profile of each subscriber, and power saving history according to guide information. More specifically, the power saving history according to the guide information may include, for example, whether or not the actual power consumption is reduced, the reduced power amount, information on the load device that has performed the power reduction, etc. .

The receiving unit 321 can receive a request signal for reducing the power consumption from the power supply related server 600 before the start of the period / time period in which the power consumption reduction is required.

For example, the power supply related server 600 may transmit a request signal one week before, one day before, or one hour before the start of the period / time zone in which the power usage reduction is required. This is to induce subscribers to be informed of the reduction of power usage before the period / time required to reduce power usage, thereby inducing actively reducing power usage.

The selecting unit 331 can select at least one subscriber who wants to request a reduction in power consumption according to a predetermined criterion considering power consumption, power consumption over time, probability distribution of savings due to compensation, and the like. Accordingly, the server 300 can select a subscriber that is predicted to be able to perform a power saving reduction request at a minimum cost. Alternatively, the server 300 can select a subscriber whose response to the power saving request is expected to be high.

For example, the selection unit 331 determines the amount of power consumption in the reduction request time zone, the estimated value of the strategy usage amount in the reduction request time zone, the response rate / reduction power amount of the existing power use reduction, According to one embodiment of the present invention, the probability distribution of savings due to compensation can be estimated based on the actual saved power amount for past power usage reduction requests can do. In addition, a change in the user's usage of the rate change due to the progressive step can also be used to generate a probability distribution of savings based on the compensation. The probability distribution of the reduction goal achievement can vary depending on the load usage time of the reduction target time or the predicted power usage of the load device as a whole.

For example, FIG. 13 is a diagram illustrating a probability distribution of savings achieved with respect to a requested amount of savings according to different compensation amounts per unit usage estimated for each subscriber. In FIG. 13, the abscissa indicates the amount of the requested amount of savings, and the ordinate indicates the probability of achieving the requested amount of reduction. Different curves mean different amounts of compensation per unit usage. The amount of compensation per unit usage can vary depending on the time of the request for reduction because the unit cost of power generation changes due to weather conditions, reserve for electricity supply, and so on.

The selection unit 331 selects a minimum value F ( _i ) considering the probability distribution F _i (?; P) of the reduction based on compensation made for each individual user for the amount of required power W Cost reduction Calculate the amount of compensation required to satisfy the required power and the amount of reduction demand (Δ _i ) for each individual user (i = 1, ..., n).

FindΔ _i , p

that minimizes

such that

In this case, the probability distribution function of the savings is estimated for each individual device, and it is possible to calculate the savings request amount for each device. Alternatively, the selection unit 331 may determine the response rate and the expected value of the use- The subscriber may be selected to meet the amount of energy savings involved

In addition, the selection unit 331 can select a subscriber by calculating an estimated amount of required reduction in electric power that is increased by a certain amount with respect to the amount of reduction requested electric power included in the request signal. This is to prepare for the presence of subscribers who do not participate in power saving among the selected subscribers.

For example, when receiving the request signal (requesting a reduction of 10,000 KWh at 2:00 tomorrow afternoon), the selection unit 331 calculates the total amount of power consumption The subscriber can be selected so that the expected amount of saved power is 20,000 KWh. At this time, when the power saving response rate for the existing guidance information is 50%, the selecting unit 331 calculates twice the amount of power required for saving included in the request signal as the estimated amount of power required for saving, .

In addition, the selection unit 331 can select subscribers who want to request reduction in power use, excluding subscribers who normally use only the basic power in the time period for saving a demand. Here, the basic power may mean the standby power of the load device or the minimum power for maintaining the activated state. The selection unit 331 can be excluded from the selection of power saving because the possibility of power saving is very low in a load device using only basic power.

For example, the selection unit 331 calculates the basic power usage amount for the predicted power usage amount in the required power saving use time period for all subscribers, determines the calculated power value as the amount of power that can be saved, It is possible to calculate the amount of power demanded and the amount of power demanded to be saved within the available power amount.

When the selected subscriber uses a plurality of load devices, the selection section 331 may determine the total amount of saved power required for the selected subscriber, the amount of power required for saving by load device or load device have.

When the request signal includes information on a specific area where power saving is requested, the selecting unit 331 can set a subscriber who wants to request power saving among the subscribers residing in the specific area.

The transmitting unit 322 can transmit the guidance information (1) for reducing the power consumption to the communication device 400 of the subscriber selected by the selecting unit 331.

For example, the guidance information may include information such as the time period during which power saving is required, the amount of power required for saving, the amount of power that can be saved for the entire load device or the individual load device, a guide for reducing power consumption (for example, , Raise the refrigerator / freezer temperature of the refrigerator, unplug the unused electronics, etc.), and compensation information for reducing power usage.

The monitoring unit 332 can monitor the amount of power consumption by the selected load device of the subscriber after transmitting the guide information. This is to grasp whether the use of power by the load device of the subscriber is actually reduced or the amount of the reduced power to correspond to the guide information, and to give compensation based on this.

The compensation management unit 333 can provide a predetermined compensation to the subscriber in proportion to the reduced power consumption when the power usage by the load device of the selected subscriber decreases according to the transmitted guide information. More specifically, the compensation management unit 333 can give compensation for the power usage fee.

For example, the compensation management unit 333 may award a compensation in the form of a point payment method that is available for a power utility discount or a power usage fee payment. Alternatively, the compensation management unit 333 may provide cash, gifts, coupons, etc. received from the sponsor server 610 as compensation.

Further, the transmitting unit 322 can transmit information (hereinafter, saving information) about power saving according to the subscriber-specific guide information to the power supply related server 600, and the power supply related server 600 can transmit the power saving related information And determines the compensation corresponding to the power saving amount and the reduced power amount included in the power saving information and transmits the information on the compensation to the server 300. Therefore, the compensation management unit 333 can give compensation to the subscriber based on the compensation information received from the power supply related server 600. [

On the other hand, the compensation management unit 333 determines a compensation granting criterion based on whether or not the power saving is performed according to the guidance information and the reduced power amount, and may grant compensation to the corresponding subscriber based on the compensation granting criterion.

The transmitting unit 322 can transmit the information (hereinafter referred to as compensation information) (2) related to the given compensation to the communication device 400 of the subscriber.

The communication device 400 may further include an input unit 440 that receives a power saving command for at least one load device by executing a power related application, It is possible to transmit the power saving command signal to the corresponding load device 500.

For example, the communication device 400 receives a command / selection regarding operation of each load device (e.g., power on / off, temperature control of the air conditioner / refrigerator, etc.) from the subscriber through the input unit 440 . More specifically, the input unit 440 may select a load device to save power from a subscriber, or input a power saving scheme for each load device.

When receiving the power saving command signal (1), the load device 500 can reduce the power consumption so as to correspond to the power saving command signal. Furthermore, the load device 500 can transmit a response (hereinafter referred to as a response signal) (2) to the communication device 400 as to whether or not the power saving operation has been performed so as to correspond to the power saving command signal.

For example, if the load device 500 is a refrigerator and the power save command signal includes a recommended refrigerator / freezer temperature for a certain period of time, then the recommended refrigerator / freezer temperature may be maintained for a predetermined time. Alternatively, if the load device 500 is a computer and the power save command signal includes a power off command, the computer can be powered off.

The power entry point is, for example, a node where power is drawn into a plurality of load devices, such as the power entry point of a switchboard or a distribution board of each home. Hereinafter, the operation of the power information collecting unit 110 according to the present embodiment will be described in more detail with reference to FIG.

In this embodiment, the power information collecting unit 110 first performs the power signal measuring step S112. The power signal measuring step (S112) measures the unprocessed power information waveform of the current and voltage through the energy measuring device installed at the power input point and a single sensor.

Next, the power information collecting unit 110 performs a snapshot extracting step S114. The snapshot extraction step (S114) collects a voltage or current snapshot of the AC waveform of a predetermined period. In the present embodiment, it is preferable to extract current snapshots of the voltage and high frequency of AC waveforms.

Next, the operation state extracting unit 120 extracts a change pattern of the operation state or operation state of the load device by classifying the normal or transient state of the power change from the collected voltage or power information. This will be described in more detail with reference to FIG.

Referring to FIG. 9, the operation state extraction unit 120 first performs power information and reference point extraction step S116. That is, real time power consumption and power quality information are extracted and reference points for distinguishing normal or transient states are extracted.

In the present embodiment, it is preferable that the reference point is a power usage amount that is always on without being switched on / off by the individual load device through real-time power consumption and power quality information extraction and is constantly used without fluctuation.

Next, the transient response separation step (S118) extracts a transient state section in which the ON / OFF state or the operating state is changed by the operation of the individual load device in the power consumption amount.

Further, in this embodiment, the operation state extraction unit 120 may perform the noise removal step (S120). The noise removing step (S120) removes the meaningless high-frequency noise signal generated in the power signal measurement of the total power consumption.

In addition, the operation state extracting unit 120 classifies the snapshot according to the extracted operation state or change pattern of the operation state. For example, the snapshot extraction frequency may be much higher than the normal state when the transient response operation is determined.

Referring again to FIG. 9, snapshots of events are classified according to on / off states before clustering for individual load devices through on / off event detection step S122.

Next, the state transition change detection step (S124) detects and classifies the change pattern of the operation state with respect to loads having continuous multi-step or multi-step on / off operation.

The real-time total power data processing step S126 after detecting the state transition change generates power information data calculation, storage and transmission data packets for the total energy usage and power quality information for the real-time power consumption service.

The data set generating unit 130 according to the present embodiment generates a separately set message data set which is matched with the change pattern of the operation state or the operation state through the signal correlation according to the power use characteristics of the individual load devices . This will be described in more detail with reference to FIG.

Referring to FIG. 10, the data set generation unit 130 performs a load feature extraction step (S 130).

In the present embodiment, the load characteristic extraction step (S130) uses the snapshot, transient response, on / off event, and state transition change information extracted from the total power usage data to calculate a signal correlation . The signal correlation may include voltage / current correlation, high frequency distortion, current / power signal distortion, valid / reactive power correlation, and the like.

Next, the data set generation unit 130 performs on / off event matching and pattern matching load classification for generating a data set.

That is, the on / off event matching step (S132) classifies the on / off operation events for the individual devices into pairs for the same device based on the generated signal correlation, and the pattern matching load classification step (S134) Based on the signal correlation, multi-step or continuous change characteristics for the same device are classified into on / off action events and associated groups.

Next, the data set generation step (S136) generates a data set bound to the association group through on / off event matching and pattern matching load classification.

When a data set is generated, the transmitter 140 transmits the generated data set to the labeling server 200, which recombines the data set and generates labeled power information.

Prior to transmission, in this embodiment, it is possible to compress a generated data packet in the energy measuring apparatus to facilitate the transfer of a large amount of data to a specific server.

It is also possible to transmit the power consumption amount and quality information data necessary for real-time power energy information service together.

Next, with reference to Figs. 8 to 10, the snapshot extraction (i.e., power signal sampling) cycle and the information processing efficiency according to the present invention will be described in detail.

First, it is important that the power information collecting unit 110 appropriately selects the snapshot extraction period. When the snapshot extraction frequency is lower than a specific value, for example, less than once per second, it is difficult to distinguish between different individual load devices due to the low resolution of the transient state section of the load device. When the value is higher than the threshold value, for example, the resolution for the transient state section is excessively high from several thousands to several tens of thousands per second, and errors such as recognizing the same load device as different load devices may occur. Therefore, the snapshot extraction period for efficient pre-information processing of the energy measuring device at the power input point is suitable from about 10 to 900 times per second.

Next, a snapshot is extracted 15 times per second at all times in the snapshot extraction step S114 (for example, in the snapshot extraction step S114), but when there is no change in the operation state, Shot, or 15 representative values only, and selecting all 15 of them when the operation state change is detected, thereby increasing the resolution of the transient state section separately.) The information processing after the operation state extraction can be streamlined. That is, although the resolution of the transient state interval, which is essential for analyzing the energy usage information for each device, increases, the load related to the data traffic decreases (for example, when the transmission unit 140 periodically transmits data once per second, The system is able to transmit only one representative value calculated through the selected snapshot or the divisional quadrature method and the 15 snapshots at the same time in the transient state), thereby improving the compatibility between the energy measuring instrument and the server It is also possible to perform some or all of the steps performed by the on / off event detection step S122, the state transition change detection step S124, and the data set generation unit 130 through the server.

Hereinafter, a labeling server 200 for receiving the data set generated by the power point energy measuring apparatus 100 according to the above-described embodiment and generating labeled power information will be described with reference to FIG.

The labeling server 200 according to the present embodiment is a system that performs a process such as machine learning and automatic labeling based on the received clustering data set for each load and real-time power usage and power quality information data sets, Energy usage information and savings tips consulting. That is, the labeling server may be a large-capacity data processing apparatus that generates various energy saving solutions and consulting by processing the total energy information received from the energy measuring apparatus and the individual energy information for each department, and exposes the energy saving solution and consulting to the user.

That is, the labeling server 200 according to the present embodiment performs a specific post-information processing process through a software algorithm. The process reclassifies an anonymous load clustering data set into a multidimensional plane according to a reference area such as active power, reactive power, time, etc., sets the classification interface in the same load device through machine learning, Continuous change, continuous start, etc.

(1 + 2 + 3 or A + B + C, etc.) to the same device that can recognize the sub-components of the individual load device Automatic labeling is performed through a matching operation with the naming data set (refrigerator, washing machine, air conditioner, etc.) of the stored individual load devices.

At this time, manual labeling is performed by means such as manually turning on / off the device and checking the corresponding time for energy devices that are not automatically labeled due to data not in the named data set. The manually generated data is then added back to the pre-collected data set and used for future automatic labeling.

This will be described in more detail with reference to FIG.

Referring to FIG. 11, the labeling server 200 according to the present embodiment includes a receiving unit 210, a recombining unit 220, and a labeling unit 230.

First, the receiving unit 210 receives the data set generated by classifying the power information based on the component stages constituting the individual load devices.

Next, the recombining unit 220 reclassifies the received data set to a multidimensional plane according to the operating characteristics of the individual load devices, and maps the data sets according to the time domain to recombine.

Prior to this, the recombiner 220 may perform the data decompression step (S202) first. That is, when the power acquisition point energy measuring apparatus 100 transmits the compressed data, the data compression can be released to increase the speed of the software algorithm execution.

Once decompressed, the recombiner 220 maps the reclassified data to the power usage trends in the time domain to recombine the components in the same load device. This will be described in more detail with reference to FIG.

12 is a flowchart illustrating respective steps performed by the recombiner 220 according to an embodiment of the present invention.

Referring to FIG. 12, the large class load device classifying step S1204 classifies the distribution planes according to the load operation characteristics (on / off, multi-step, continuous change, always-on start) .

In the following feature-specific clustering step (S1206), the multidimensional plane is reconfigured so as to facilitate the boundary setting within the distribution plane by linking the clustering data set and the classification load device classification. Active power, reactive power, time, etc., can be used as a reference area to reconstruct the multidimensional plane.

When the multidimensional plane is reconfigured, the machine learning step (S1208) generates the operation classification of the individual load devices or the boundary classification criterion between the parts using the clustering result by the energy device and the machine learning method based on the state classification algorithm such as the artificial intelligence network. The specific load device classifying boundary setting step S1210 classifies the data by performing load classification at the individual parts level for the clustering data using the machine learning boundary classification standard. At this time, the detailed load classification of bearings is determined from the total power amount to the part level for individual energy devices.

The next time-domain mapping step S1212 maps the data set for the anomalous parts reclassified in the process to real-time data in the time domain.

The classification step S1214 divides the mapped data into component levels by various color or user-recognizable display methods.

Next, in the same load reconfiguration step (S1216), the sub-components in the individual load devices generated in the division step are combined to create a group as a load device that can be recognized by the user. For example, the compressor, the motor, the lamp, and the control circuit characteristics generated in the division step are combined and grouped into a refrigerator. (Internal numbers 1, 2, 3, and A, B, C, etc.).

After performing the recombination step, the labeling unit 230 labels the recombined data set. For example, for bearer temporary mark data classified as individual load devices, the name of the load device is automatically matched with the previously stored load device data set. For example, A, B, and C may be automatically named as refrigerators, TVs, and washing machines through a matching algorithm with data patterns and stored data.

Also, in this embodiment, labeling may be input manually. Despite the automatic labeling, the developer or user manually names and enters the device manually for load balancers that do not match the default load device data. It is also possible to utilize the on / off time of the device.

In addition, for individual load devices that have been manually labeled, the corresponding data can be stored separately with the name of the load device to extend the set of offloaded load device data.

Furthermore, the labeling server 200 may provide data interpretation information using the individual load appliance energy usage information. It is also possible to generate a specific data set by applying data analysis based on behavioral psychological analysis algorithms to the total power and individual load energy usage patterns.

Also, it is possible to automatically generate expert consulting tips that can lead to user's energy saving through the above data analysis.

Furthermore, it is possible to provide all services that provide total energy, individual load device usage, energy saving consulting, etc. to a specific building or unit household through an energy IT specialist.

For example, in various energy consulting, it is possible to detect a component aging state or failure state of an individual load device by detecting a change of a clustering data set classified at a component level with respect to the state of an individual load device, and provide the same to a user.

According to the above-described embodiments, it is possible to extract component individual energy usage information of various load devices by performing a combination of the hardware algorithm of the meter and the software algorithm of the server for the total power usage information at the power entry point.

In addition, by flexibly combining the server's software algorithms with a single energy measurement device, high energy savings can be achieved by extracting detailed energy usage information of individual load devices without the high cost of system installation through multiple devices . Particularly, it is possible to acquire energy usage information at a level equal to or higher than the branch circuit level without adopting a large number of sensors in the distribution board.

In summary, in the present invention, in extracting the energy usage information of the individual load devices from the total electric energy usage information measured at the power entry point, the specific server does not perform the entire algorithm, but the energy measurement devices Data set generation, etc.) and servers (post-processing processors, software algorithms, labeling and generation of energy saving tips, etc.). In other words, pre-information processing is performed so as to have a resolution capable of distinguishing between parts in a single energy measuring apparatus, and the server mainly performs data storage, pattern analysis, and data utilization, It is possible to secure flexibility in storage / management.
