Description

Server, method and computer program for monitoring electricity usage in a building

[0001] The present invention relates to a server, method and computer program for monitoring electricity usage in a building.

[0002] Electricity rates are categorized based on the intended use of electricity, and this distinction is referred to as "contract type." Contract types reflect various policies, such as industrial protection and price management, and thus lead to rate differences. Contract types include residential, general, educational, industrial, agricultural, streetlight, and standby and temporary power.

[0003] Electricity rates consist of a base rate, a power usage rate, a climate and environment rate, and a fuel cost adjustment rate. The base rate reflects the basic infrastructure and management costs required for KEPCO to provide electricity services, regardless of usage. It is calculated by multiplying the applicable electricity by the unit price. The power usage rate reflects costs incurred based on usage.

[0004] However, in buildings owned by a single company or individual, electricity bills are not an issue. However, in buildings shared by multiple people, such as commercial buildings, officetels, and knowledge industry centers, there are many factors to consider when calculating electricity bills for both the private areas used directly by one person and the common areas used by multiple people. The calculation method varies depending on the building, but the basic rate usually follows the equal area distribution method, and the usage rate is calculated by dividing the total usage rate by the total usage, calculating the unit price per kWh, and then multiplying the usage by the unit price per kWh. For electricity bills in common areas, various criteria are usually applied, such as the area ratio, the operating hours ratio, the number of employees using the elevator, and the number of vehicles using the parking lot.

[0005] In addition, because there are various cases, such as customers who have installed KEPCO AMI (Advanced Metering Infrastructure) power meters for each unit / room in each building, customers who have installed private power meters, and customers who have installed a combination of KEPCO AMI power meters and private power meters, it is more difficult to reduce usage and settle bills.

[0006] Therefore, in buildings that are used jointly, each household / room must be able to know when and how much to reduce electricity usage, and if possible, there must be a reasonable calculation and justification that is in line with the basic rate and electricity rate required by KEPCO and that everyone can agree on, in order to reduce electricity usage.

[0007] According to the present invention, even carbon neutrality for buildings can be achieved.

[0008] The present invention is intended to solve the problems of the prior art described above, and provides an electricity usage monitoring server, method and computer program that can monitor the electricity usage of a building in real time, share the monitoring status, and check and manage the electricity usage and maximum demand power in the building in real time.

[0009] In addition, we aim to provide an electricity usage monitoring server, method and computer program that can settle electricity bills in a manner that can be reasonably accepted by stakeholders within a building.

[0010] However, the technical tasks that this embodiment seeks to accomplish are not limited to the technical tasks described above, and other technical tasks may exist.

[0011] As a means for achieving the above-described technical problem, an embodiment of the present invention provides an electricity usage monitoring server including: a server for monitoring electricity usage in a building, the server including: an electricity usage measurement unit for measuring primary electricity data corresponding to the total electricity usage of the building from a power meter connected to a KEPCO meter at preset intervals, and secondary electricity data corresponding to the electricity usage of each room in the building at preset intervals from a multi-channel power meter connected to a distribution panel of the building or a plurality of intelligent power meters connected to each of a plurality of distribution panels of the building; a determination unit for presetting a peak electricity value for the building and determining whether the primary electricity data exceeds the preset peak electricity value; a notification unit for providing a notification service to a user of the building when the primary electricity data exceeds the preset peak electricity value; and a unit for calculating the electricity rate and cost for each room based on the primary electricity data and the secondary electricity data.

[0012] Another embodiment of the present invention provides a method for monitoring electricity usage in a building, comprising: measuring primary power data corresponding to the total electricity usage of the building from a power meter connected to a Korea Electric Power Corporation (KEPCO) meter at preset intervals; measuring secondary power data corresponding to the electricity usage of each room of the building at preset intervals from a multi-channel power meter connected to a distribution panel of the building or a plurality of intelligent power meters connected to each of a plurality of distribution panels of the building; pre-setting a peak power value for the building and determining whether the primary power data exceeds the preset peak power value; providing a notification service to a user of the building when the primary power data exceeds the preset peak power value; and calculating the power and cost to which the rate is applied for each room based on the primary power data and the secondary power data.

[0013] Another embodiment of the present invention provides a computer program stored in a computer-readable recording medium including a sequence of commands for monitoring electricity usage in a building, wherein the computer program, when executed by a computing device, measures primary power data corresponding to the total electricity usage of the building from a power meter connected to a Korea Electric Power Corporation (KEPCO) meter at preset intervals, measures secondary power data corresponding to the electricity usage of each room in the building at preset intervals from a multi-channel power meter connected to a distribution panel of the building or a plurality of intelligent power meters connected to each of a plurality of distribution panels of the building, presets a peak power value for the building, determines whether the primary power data exceeds the preset peak power value, provides a notification service to a user of the building when the primary power data exceeds the preset peak power value, and calculates the electricity and cost to be applied to each room based on the primary power data and the secondary power data.

[0014] The above-described problem-solving methods are merely exemplary and should not be construed as limiting the present invention. In addition to the exemplary embodiments described above, additional embodiments may exist, as described in the drawings and detailed description of the invention.

[0015] According to any one of the aforementioned means for solving the problem of the present invention, a building's electricity usage can be monitored in real time and the monitoring status can be shared. This provides an electricity usage monitoring server, method, and computer program that can check and manage electricity usage within a building in real time.

[0016] In addition, the present invention can provide an electricity usage monitoring server, method, and computer program that can settle electricity bills in a way that stakeholders within the building can reasonably agree on. Ultimately, the core of the present invention is threefold: first, it enables savings by creating visible electricity; logical designation of each unit / room is possible from a central server regardless of the building environment or frequent changes in units / rooms, making meter reading and inquiry much easier; and by showing the overall status and each unit / room through alarms, it creates a justification for participating in conservation and settlement, thereby greatly eliminating social conflicts. Second, through data collection for each section within the building, which is the secondary side, a market where AI can be applied will be formed, that is, a variety of energy efficiency markets through AI will be created, such as identifying excessive heating and cooling equipment, low-efficiency equipment, and equipment with signs of failure through predictive maintenance. Third, the logic that the best energy source is energy conservation may be re-emerged. That is, while energy savings are achieved through hardware such as zero-energy buildings at the time of construction, activities to reduce usage to achieve the carbon neutrality goal must also be continuously pursued after construction.

[0023] Below, with reference to the attached drawings, embodiments of the present invention are described in detail so that those skilled in the art can easily implement them. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In the drawings, irrelevant parts have been omitted for clarity of description, and similar reference numerals have been used throughout the specification to indicate similar elements.

[0024] Throughout the specification, when a part is said to be "connected" to another part, this includes not only the case where it is "directly connected" but also the case where it is "electrically connected" with another element in between. Furthermore, when a part is said to "include" a component, this should be understood to mean that, unless specifically stated to the contrary, it may include other components rather than excluding them, and does not preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0025] In this specification, the term "unit" includes a unit realized by hardware, a unit realized by software, and a unit realized using both. Furthermore, a single unit may be realized using two or more pieces of hardware, and two or more units may be realized by a single piece of hardware.

[0026] Some of the operations or functions described herein as being performed by a terminal or device may instead be performed by a server connected to the terminal or device. Similarly, some of the operations or functions described herein as being performed by a server may also be performed by a terminal or device connected to the server.

[0027] The configuration and main logic of the present invention are to connect a primary KEPCO meter and a power meter capable of measuring per minute, and to connect a multi-channel power meter to a distribution panel on the secondary side or to connect a smart power meter to each of a plurality of distribution panels on the secondary side so as to transmit power data on the secondary side to a central server. In the present invention, the smart power meter is an electronic power meter capable of measuring power data and transmitting it to an electricity usage monitoring server described below, and may include, for example, a KEPCO AMI (Advanced Metering Infrastructure) power meter.

[0028] The most important basic logic of the present invention is that "when the rate-applicable power of the entire building (primary side) is determined, the same maximum demand power for each unit / room (secondary side) is determined as the rate-applicable power for each unit / room." This is tentatively defined as the so-called "equalization theory." This is because the rate-applicable power of the entire building is made up of the sum of the rate-applicable power of the secondary side. Therefore, if each unit on the secondary side reduces its usage and generates visible electricity through reasonable rate settlement according to its efforts, the building's cost savings and carbon neutrality are realized.

[0029] Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0030] FIG. 1 is a block diagram of a system for monitoring electricity usage in a building. Referring to FIG. 1, the electricity usage monitoring system (1) may include a multi-channel power meter or intelligent power meter (110-1), an intelligent energy meter (110-2), an electricity usage monitoring server (120), and a user terminal (130). In the present invention, the intelligent energy meter (110-2) may be a device for measuring the usage of energy, including water, gas, heating, and hot water, for example. However, the above components (110-1 to 130) are merely exemplary components that can be controlled by the electricity usage monitoring system (1).

[0031] Each component of the electricity usage monitoring system (1) of Fig. 1 is generally connected via a network. A network refers to a connection structure that enables information exchange between each node, such as terminals and servers, and includes a local area network (LAN), a wide area network (WAN), the Internet (WWW), wired and wireless data communication networks, telephone networks, wired and wireless television communication networks, etc. Examples of wireless data communication networks include, but are not limited to, 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), Wi-Fi, Bluetooth communication, infrared communication, ultrasonic communication, visible light communication (VLC), LiFi, etc.

[0032] The electricity usage monitoring system (1) can monitor the electricity usage of a building in real time from the electricity usage monitoring server (120). For example, the electricity usage monitoring server (120) can measure the total electricity usage of the building and the electricity usage of each room in real time from a power meter (5-minute meter) connected to a KEPCO meter, a multi-channel power meter connected to the building's distribution panel, and multiple intelligent power meters connected to each of the building's multiple distribution panels.

[0033] More specifically, the electricity usage monitoring system (1) connects a KEPCO meter and a power meter capable of minute-by-minute measurement to transmit usage data to a central server, thereby sending an alarm to a designated terminal when a promised peak power value is reached. This function can be set up as an alarm function using, for example, the KEPCO Power Planner. In this case, the alarm can be determined and transmitted based on only the primary power data.

[0034] The electricity usage monitoring system (1) is configured to transmit electricity usage data to a central server by installing a multi-channel power meter in a secondary measurement distribution panel or by installing multiple intelligent power meters in each of multiple distribution panels. The electricity usage monitoring system (1) may also be configured to install multiple intelligent power meters in each of multiple distribution panels (or in some of the multiple distribution panels) while installing a multi-channel power meter in the distribution panel.

[0035] The central server is configured to create a database of each household's usage and peak demand data, allowing for cross-comparison. The electricity rate applicable to each secondary unit / room is determined according to the "Equity Theory." The basic rate is calculated by dividing the secondary rate applicable electricity by the primary rate applicable electricity, multiplying this result by the total basic rate. All other details must comply with Article 68 (Determination of Rate-Applicable Electricity) of the KEPCO Basic Supply Terms and Conditions.

[0036] The electricity usage monitoring system (1) can share the building's electricity usage status measured by the electricity usage monitoring server (120) with the user terminal (130).

[0037] Through this, the electricity usage monitoring system (1) can check and manage electricity usage within the building in real time. For example, if the electricity usage of the building exceeds a preset target usage amount or a preset maximum demand power (peak power), the electricity usage monitoring server (120) can share the relevant status with the user terminal (130) so that the building user can adjust the electricity usage.

[0038] Additionally, the electricity usage monitoring system (1) can settle electricity bills in a manner that is reasonably acceptable to stakeholders within the building through the bill settlement server (150). For example, the bill settlement server (150) can share the results of the building's electricity usage monitoring with the user terminal (130) and settle electricity bills for each room based on the monitoring results.

[0039] Additionally, the billing server (150) can calculate water and gas charges for each room via an intelligent energy meter (110-2). According to the present invention, not only electricity savings but also energy savings, including water, gas, heating, and hot water, can be achieved, thereby achieving carbon neutrality for the building.

[0040] Hereinafter, each configuration of the electricity usage monitoring server (120) will be specifically examined with reference to FIGS. 2 to 5.

[0041] Figure 2 is a configuration diagram of an electricity usage monitoring server. Referring to Figure 2, the electricity usage monitoring server (120) may include a labeling unit (200), an electricity usage measurement unit (210), a judgment unit (220), a notification unit (230), a cost calculation unit (240), and a control unit (250).

[0042] However, the above components (210 to 250) are merely exemplary components that can be controlled by the electricity usage monitoring server (120). For example, as illustrated in FIG. 2, the electricity usage measurement unit (210), the judgment unit (220), the notification unit (230), the cost calculation unit (240), and the control unit (250) can be connected simultaneously or at time intervals.

[0043] FIG. 3 is an exemplary drawing for explaining an electricity usage monitoring server connected to a multi-channel power meter and / or an intelligent power meter, and FIG. 4 is an exemplary drawing for explaining electricity usage monitoring for each room.

[0044] The labeling unit (200) can separate rooms / units in advance using data pre-designated for each auxiliary circuit breaker of the distribution board or branch board and each room / unit in case there are multiple rooms / units on a single floor. For example, the labeling unit (200) can separate rooms / units in advance by designating the auxiliary circuit breakers a, b, and c of the branch board as room 101, and the auxiliary circuit breakers d, e, and f as room 102.

[0045] In addition, the labeling unit (200) can re-separate the rooms / units of the auxiliary circuit breakers when the top surface of a specific floor changes. For example, when the first floor of a building changes from two to three offices, the auxiliary circuit breakers of the distribution board separated into rooms a, b, and c as room 101, d, e, and f as room 102 can be re-separated into rooms a, b as room 101, c, d as room 102, and e, f as room 103.

[0046] Referring to FIG. 3, the electricity usage monitoring server (300) can measure the total electricity usage of the building, the electricity usage by floor of the building, and the electricity usage by room / unit from the power meters (310, 320 to 350) installed in the building.

[0047] For example, the electricity usage monitoring server (300) can monitor the building's total electricity usage from a power meter (310) combined with a KEPCO meter (30). Alternatively, the electricity usage monitoring server (300) can also monitor the building's total electricity usage by utilizing the KEPCO Power Planner alarm function. In the present invention, the power meter (310) can also be a smart power meter, including a KEPCO AMI power meter.

[0048] In addition, the electricity usage monitoring server (300) can monitor the electricity usage of each floor or each room from a multi-channel power meter (320) connected to a distribution panel (31) and / or a plurality of intelligent power meters (330 to 360) connected to distribution panels (32 to 35) installed on each floor.

[0049] Specifically, the electricity usage measuring unit (210) can measure primary power data corresponding to the total electricity usage of a building from a power meter (310) connected to a KEPCO meter (30) at preset intervals. For example, the electricity usage measuring unit (210) can measure and store primary power data from the power meter (310) every minute.

[0050] Here, the primary power data may correspond to the total electricity usage of the building measured from the KEPCO meter (30) installed in the building, and the power to which the rate is applied, which is the basis for the basic rate, may be determined based on the usage of the primary power data.

[0051] The electricity usage measuring unit (210) can measure secondary data corresponding to the electricity usage of each room in the building at preset intervals from a multi-channel power meter (320) connected to a distribution panel (31). Alternatively, the electricity usage measuring unit (210) can measure secondary data corresponding to the electricity usage of each room at preset intervals from a plurality of intelligent power meters (330 to 360) connected to distribution panels (32 to 35).

[0052] For example, the electricity usage measurement unit (210) can measure and store secondary electricity usage data every minute from a multi-channel power meter (320) and / or multiple intelligent power meters (330 to 350).

[0053] Referring to Fig. 4, the electricity usage measurement unit (210) can monitor the total electricity usage of the building at preset intervals from the power meter (410) connected to the KEPCO meter (41). For example, the power meter (410) for monitoring the electricity usage of the building can be connected to the KEPCO meter (41) on the primary side of a transformer (42) installed in the building.

[0054] The electricity usage measurement unit (210) can monitor the usage of each unit / room of the building from a multi-channel power meter (420) connected to a distribution panel (43) and a plurality of intelligent power meters (430 to 460) connected to floor-by-floor distribution panels (44 to 47).

[0055] For example, when the rate application power of the entire building (primary side) is determined, the electricity usage measurement unit (210) determines the secondary maximum demand power of each unit / room in the same time zone as the rate application power of each unit / room, and at this time, the basic rate can be calculated by multiplying the value obtained by dividing the secondary rate application power by the primary rate application power by the overall basic rate.

[0056] Referring to the embodiment illustrated in FIG. 4, the electricity usage measurement unit (210) can measure the total electricity usage of the building from the power meter (410), the primary electric energy of 180 kWh (411) at 2 o'clock, and the maximum demand power of 720 kW (412) accumulated for 15 minutes, and can convert them into data.

[0057] Looking at the electricity usage and secondary electric energy by floor at the same time, the electricity usage measuring unit (210) can measure the 14:00 electricity usage of 40 kWh (421) and the maximum demand power of 160 kW (422) on the first floor from the intelligent power meter (430) connected to the first floor distribution panel (44) and convert it into data. And, the electricity usage measuring unit (210) can measure the 2-hour electricity usage of 45 kWh (431) and the maximum demand power of 180 kW (432) on the 2nd floor from the intelligent power meter (440) connected to the 2-story distribution panel (45), can measure the 2-hour electricity usage of 45 kWh (441) and the maximum demand power of 180 kW (442) on the 3rd floor from the intelligent power meter (450) connected to the 3rd floor distribution panel (46), can measure the 2-hour electricity usage of 50 kWh (451) and the maximum demand power of 200 kW (452) on the 4th floor from the intelligent power meter (460) connected to the 4th floor distribution panel (47), and can digitize the electricity usage for each floor and each room / room.

[0058] Meanwhile, the electricity usage measurement unit (210) can manage and store electricity usage for each room by adding up the electricity usage data for each floor measured from a multi-channel power meter (420) and / or multiple intelligent power meters (430 to 460) for each room.

[0059] The judgment unit (220) can preset a peak power value for the building and determine whether the primary power consumption data exceeds the preset peak power value. For example, the judgment unit (220) can set a target usage amount for the entire building's electricity consumption.

[0060] In addition, the judgment unit (220) can preset a maximum demand power peak value for the primary power data and determine whether the primary power data exceeds the preset maximum demand power peak value.

[0061] That is, the judgment unit (220) can preset the peak value for the primary electric energy usage. For example, the judgment unit (220) can preset the maximum demand power peak value of the primary electric energy to 600 kW, and when the maximum demand power of the primary electric energy measured from the power meter (440) is measured as 720 kW, it can be determined that the primary electric energy at that time exceeds the preset maximum demand power peak value of 600 kW.

[0062] The notification unit (230) can provide a notification service to building users when the primary power data exceeds a preset peak power value. In addition, the notification unit (230) can provide a notification service to building users when the primary power data exceeds a preset maximum demand power peak value.

[0063] For example, if the maximum demand power peak value is preset to 600 kW, the notification unit (230) can provide a notification service to the user terminal (130) when the primary energy reaches 540 kW, which is 90% of the maximum demand power peak value.

[0064] For example, when the primary energy of the building reaches 540 kW at 2 o'clock, the notification unit (230) can transmit the primary energy and secondary energy status at 2 o'clock to the building's users in real time through user terminals (130), including SMS, KakaoTalk, and monitors (IPTV) (see FIG. 7).

[0065] The notification unit (230) can provide notification services via the monitors of each user in each room using IPTV. For example, the notification unit (230) can provide real-time information on the building's electricity usage status, such as by displaying a pop-up window on the user's monitor by combining the electricity usage monitoring server (120) with IPTV.

[0066] According to the present invention, after setting a target for the power to be applied with a rate, when the target is reached, an alarm is sent to each secondary unit / room via SMS, KakaoTalk, monitor (IPTV), etc., and the dedicated section makes an effort to reduce the power consumption by each unit / room, and the public section builds a system that can automatically control the public facilities, thereby actively inducing reduction in the usage.

[0067] Additionally, by providing before and after data on how much usage was reduced after actual usage reduction activities, it is possible to visualize usage reductions for stakeholders in the building, thereby reducing usage and carbon emissions.

[0068] The cost calculation unit (240) can calculate the power and cost to be applied to each room based on the primary power data and secondary power data.

[0069] Specifically, the cost calculation unit (240) can derive the electricity usage and maximum demand power for each room based on the secondary power data. When the power applicable to the rate for the building is determined from the primary power data, the cost calculation unit (240) can calculate the power applicable to the rate for each room based on the maximum demand power of the secondary power data for the corresponding time zone. Here, the power applicable to the rate is the power that serves as the basis for calculating the basic rate, and the maximum demand power refers to the power that is accumulated and calculated every 15 minutes by a power meter that can measure the maximum demand power.

[0070] Referring to the embodiment illustrated in FIG. 4, when the maximum demand power of 720 kW, which is accumulated from 13:45 to 14:00 in the primary power amount data, is confirmed as the power subject to the rate, the cost calculation unit (240) can calculate the power subject to the rate for each floor / room based on the confirmed power subject to the rate, 720 kW, the maximum demand power for each floor in the corresponding time zone, and the secondary power amount data.

[0071] For example, if the building's total rate-applicable power is determined to be 720kW (412) at 2 o'clock, the 2 o'clock rate-applicable power for the 1st floor is 160kW (422), similarly, the 2 o'clock rate-applicable power for unit 201 on the 2nd floor is 40kW (432), the 2 o'clock rate-applicable power for unit 202 on the 2nd floor is 120kW (434), the 2 o'clock rate-applicable power for the 3rd floor is 180kW (442), and the 2 o'clock rate-applicable power for the 4th floor is 220kW (452).

[0072] Also, the basic rate according to the rate-applicable power for each room can be calculated as {(rate-applicable power for each room) / (rate-applicable power for the entire building)} X (total basic rate). Alternatively, the basic rate for each room can also be calculated as (rate-applicable power for each room) X (basic rate unit price), and since the rate-applicable power maintenance period follows the rate-applicable power period for the entire building, active participation seems possible.

[0073] In this way, the electricity usage monitoring server (120) shares and reflects the electricity usage for each room when calculating the basic rate of the building, so that stakeholders in the building can reasonably accept it and reduce the rate through voluntary usage reduction activities.

[0074] Referring again to FIG. 2, the control unit (250) can adjust the secondary power data. When the primary power data reaches a preset peak value, the control unit (250) can control the electricity usage of a preset control device. For example, when the primary power data reaches a preset peak value of 600 kW, the control unit (250) can control the electricity usage of an air conditioner or an exhaust fan in a building.

[0075] Here, the preset control device may include at least one of an air conditioner, a supply / exhaust fan, a fan, a cooling pump, and a circulation pump installed in the building. For example, the control unit (250) can determine in advance the capacity that can be saved through an inverter, such as an air conditioner, a supply / exhaust fan, a fan, a cooling pump, and a circulation pump, and immediately control the electricity usage of each control device when the primary power consumption data reaches a preset peak value.

[0076] At this time, the notification unit (230) can provide a notification service for controlling electricity usage to building users by controlling the electricity usage of a preset control device. For example, if the primary power data reaches a preset peak value and the electricity usage of at least one of the building's control devices is controlled, the notification unit (230) can transmit the corresponding information to the user terminal (130).

[0077] Figure 5 is an exemplary drawing for explaining the provision and setting of a notification service. The setting window (500) illustrated in Figure 5 is a notification setting (510) screen for an electricity usage notification service provided from an electricity usage monitoring server (120) to a user terminal (130).

[0078] Referring to FIG. 5, the electricity usage monitoring server (120) can set whether to provide notifications (511) related to the building's electricity usage for each user. For example, a customer number (512) can be assigned to each room in the building, and whether to provide notifications (511) regarding electricity usage can be set for each customer number (512). For example, the electricity usage monitoring server (120) can be set to provide notifications regarding electricity usage for room 101, and can be set to not provide notifications regarding electricity usage for room 102.

[0079] The electricity usage monitoring server (120) can set the building's electricity usage notification settings (520). For example, the electricity usage monitoring server (120) can set the building's electricity usage target (522) and whether to receive related notifications (521). In addition, the electricity usage monitoring server (120) can set the detailed settings (523) of the electricity usage target to provide a notification when a certain percentage of the set electricity usage target value is exceeded. For example, the electricity usage monitoring server (120) can provide a notification when the measured electricity usage exceeds 50% of the preset electricity usage target value, and can be set to provide a notification whenever the measured electricity usage exceeds 60%, 70%, 80%, 90%, 100%, 100%, or more. In addition, by allowing multiple selections in the detailed settings (523), a notification can be provided whenever the selected percentage is exceeded.

[0080] Additionally, the electricity usage monitoring server (120) can set the building's maximum demand power notification settings (530). For example, the electricity usage monitoring server (120) can set the building's maximum demand power target (532) and set whether to receive related notifications (531).

[0081] The electricity usage monitoring server (120) can be set to provide a notification when a specific percentage of a set maximum demand power target value is exceeded through detailed settings (533) of the maximum demand power target. For example, the electricity usage monitoring server (120) can be set to provide a notification when the measured maximum demand power value exceeds 40% of the preset maximum demand power target value, and can be set to provide a notification when it exceeds 50%, 60%, 70%, 80%, 90%, or 100%. In addition, multiple selections can be enabled in the detailed settings (533) so that a notification can be provided whenever a selected percentage is exceeded.

[0082] In this way, the electricity usage monitoring server (120) can set an electricity usage target value or a maximum demand power target value, and can also set a detailed target value attainment ratio value, thereby providing users in the building with more specific information on the building's electricity usage status.

[0083] Through this, users in the building can monitor the building's electricity usage in real time and adjust their electricity usage so that it does not exceed a preset peak value, and can also prevent excessive electricity bills in the building in advance.

[0084] Figure 6 is a flowchart of a method for monitoring electricity usage. The method for monitoring electricity usage illustrated in Figure 6 includes steps processed in time series according to the embodiments illustrated in Figures 1 to 5. Therefore, even if omitted below, the details also apply to the method for monitoring electricity usage according to the embodiments illustrated in Figures 1 to 5.

[0085] In step S610, the electricity usage monitoring server can measure primary electricity usage data corresponding to the total electricity usage of the building from a power meter connected to a KEPCO meter at preset time intervals.

[0086] In step S620, the electricity usage monitoring server can measure secondary electricity usage data corresponding to the electricity usage of each room in the building at preset intervals from a multi-channel power meter connected to the distribution panel of the building or a plurality of intelligent power meters connected to the distribution panel.

[0087] In step S630, the electricity usage monitoring server can preset a peak power value for the building and determine whether the primary power data exceeds the preset peak power value.

[0088] In step S640, the electricity usage monitoring server can provide a notification service to building users when the primary power consumption data exceeds a preset peak power value. As shown in Figure 7, the electricity usage monitoring server can provide alarms via IPTV, SMS, and SNS to encourage active energy conservation within a set time frame. If secondary power consumption is reduced, reducing the overall primary power peak value below the preset value, the electricity usage monitoring server will no longer send alarms.

[0089] In step S650, the electricity usage monitoring server can calculate the electricity usage cost for each room based on the primary power data and the secondary power data.

[0090] In the above description, steps S610 to S660 may be further divided into additional steps or combined into fewer steps, depending on the implementation example of the present invention. Furthermore, some steps may be omitted as needed, and the order of steps may be switched.

[0091] The method for monitoring the electricity usage of a building described through FIGS. 1 to 6 may also be implemented in the form of a computer program stored on a computer-readable recording medium executed by a computer or a recording medium containing computer-executable commands. Furthermore, the method for monitoring the electricity usage of a building described through FIGS. 1 to 6 may also be implemented in the form of a computer program stored on a computer-readable recording medium executed by a computer.

[0092] A computer-readable recording medium may be any available medium that can be accessed by a computer, and includes both volatile and nonvolatile media, removable and non-removable media. Furthermore, a computer-readable recording medium may include computer storage media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storing information, such as computer-readable instructions, data structures, program modules, or other data.
