[0030] The present disclosure will be described in detail with reference to the attached drawings. However, the embodiments may be implemented in various different forms and are not limited to the examples described herein.

[0031] FIG. 1 is a drawing for explaining an example of a method for providing information of a solar power generation system according to one embodiment.

[0032] Referring to FIG. 1, information on a plurality of devices (100a, 100b, 100c, 100d) obtained from a solar power generation system (1) can be displayed on a screen (10) and provided to a user.

[0033] For example, information on a plurality of devices (100a, 100b, 100c, 100d) included in a solar power generation system (1) can be obtained. Here, the plurality of devices (100a, 100b, 100c, 100d) may include a solar module (100a), an ESS (Energy Storage System) (100b), a load (100c), and a grid (100d). However, the devices included in the solar power generation system (1) are not limited thereto.

[0034] For example, a solar module (100a) may refer to a solar panel or solar panel that receives solar energy and produces electricity. In addition, the solar module (100a) may be composed of a plurality of cells. In addition, an ESS (100b) may refer to an energy storage system that stores renewable energy such as solar energy and can use it when needed. In addition, a load (100c) may refer to various types of devices that consume renewable energy. In addition, a grid (100d) may refer to a power grid that can optimize energy efficiency by exchanging produced renewable energy in both directions.

[0035] For example, information on a solar module (100a), an Energy Storage System (ESS) (100b), a load (100c), and a grid (100d) included in a solar power generation system (1) can be obtained and provided to a user. Here, the information may include, but is not limited to, power information such as power generation amount, temperature, current power amount, predicted power consumption, stored power amount, mobile power amount, and consumed power amount, as well as weather information such as wind speed, rainfall, snowfall, and sunrise / sunset times.

[0036] Accordingly, the user can remotely obtain information about the solar power generation system (1) without having to travel to the location where the solar power generation system (1) is installed. In addition, the user can obtain information about the device in which an abnormality has occurred and take action.

[0037] FIG. 2 is a schematic diagram illustrating an example of a device that provides information on a solar power generation system according to one embodiment.

[0038] Referring to FIG. 2, a device (hereinafter referred to as "device") (200) that provides information on a solar power generation system may include a communication unit (210), a processor (220), a memory (230), and a display unit (240). Only components related to the embodiment are illustrated in the device (200) of FIG. 2. Therefore, it is apparent to those skilled in the art that other general components may be included in addition to the components illustrated in FIG. 2.

[0039] The communication unit (210) may include one or more components that enable wired / wireless communication with an external server or external device. For example, the communication unit (210) may include a short-range communication unit (not shown) and a mobile communication unit (not shown) for communication with an external server or external device.

[0040] The processor (220) controls the overall operation of the device (200). For example, the processor (220) can control the input unit (not shown), the display (not shown), the communication unit (210), the memory (230), etc., by executing programs stored in the memory (230).

[0041] The processor (220) may be implemented using at least one of application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), controllers, micro-controllers, microprocessors, and other electrical units for performing functions.

[0042] The processor (220) can control the operation of the device (200) by executing programs stored in the memory (230). As an example, the processor (220) can perform at least a part of the method for providing information on a solar power generation system, which is described with reference to FIGS. 3 to 12.

[0043] The memory (230) is hardware that stores various data processed within the device (200), and can store a program for processing and controlling the processor (220).

[0044] For example, various data may be stored in the memory (230), such as power information such as power generation, temperature, current power consumption, predicted power consumption, stored power consumption, mobile power consumption, and the like, weather information such as wind speed, rainfall, snowfall, sunrise / sunset times, and data generated according to the operation of the processor (220). In addition, the memory (230) may store an operating system (OS) and at least one program (e.g., a program necessary for the operation of the processor (220).

[0045] The memory (230) may include random access memory (RAM) such as dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), CD-ROM, Blu-ray or other optical disk storage, hard disk drive (HDD), solid state drive (SSD), or flash memory.

[0046] The display unit (240) may be hardware that displays various data processed within the device (200).

[0047] For example, the display unit (240) may include a smartphone, tablet PC, PC, smart TV, media player, navigation, kiosk, wearable device, etc.

[0048] Accordingly, the user can obtain current and past information as well as predicted information of the solar power generation system through the display unit (240).

[0049] FIG. 3 is a flowchart illustrating an example of a method for providing information of a solar power generation system according to one embodiment.

[0050] Referring to FIG. 3, a method for providing information on a solar power generation system may include steps 310 to 330. However, the present invention is not limited thereto, and other general steps may be further included in the method for providing information on a solar power generation system in addition to the steps illustrated in FIG. 3. Furthermore, as described above with reference to FIGS. 1 and 2, at least one of the steps in the flowchart illustrated in FIG. 3 may be processed by the processor (220).

[0051] In step 310, the processor (220) may output an initial screen indicating a plurality of devices included in the solar power generation system and the connection relationship between the plurality of devices. Here, the plurality of devices may include at least one solar module, an ESS, at least one load, and a grid.

[0052] In step 320, the processor (220) may obtain power information of each of the plurality of devices. Here, the power information may include power generation, temperature, current power, predicted power consumption, stored power, moved power, and consumed power.

[0053] In step 330, the processor (220) can change and output the initial screen so that the movement of power between multiple devices is expressed in real time based on the power information.

[0054] For example, the processor (220) can change the shape of an image corresponding to a wire based on power information so as to determine the movement of power between devices.

[0055] Meanwhile, the processor (220) can determine whether there is an abnormality in at least one of the plurality of devices or the wires connecting the plurality of devices and change the shape of the image corresponding to the abnormal device or wire.

[0056] As an example, the processor (220) may set at least one reference point on each of the wires connecting a plurality of devices based on preset criteria, and determine whether at least one of the wires is abnormal based on power information at the at least one reference point. Furthermore, the processor (220) may change and output in real time the shape of at least one of the images corresponding to the wires on the initial screen based on the determination result.

[0057] As another example, the processor (220) may determine whether any one of the plurality of devices is abnormal based on the power information of each of the plurality of devices, and based on the determination result, change the shape of at least one of the images corresponding to the plurality of devices in real time and output it on the initial screen. In addition, if the processor (220) determines that at least one of the plurality of devices is abnormal based on the determination result, the processor (220) may output status information of the device determined to be abnormal.

[0058] For example, a device determined to have an abnormality may include at least one of a plurality of cells included in a solar module. In addition, the processor (220) may output, by displaying differently, only an image corresponding to at least one cell determined to have an abnormality among images corresponding to a plurality of cells included in the solar module.

[0059] FIG. 4 is a drawing for explaining an example of an initial screen showing the connection relationship of multiple devices according to one embodiment.

[0060] Hereinafter, with reference to FIG. 4, an example of a processor (220) outputting an initial screen indicating the connection relationship between multiple devices will be described.

[0061] Referring to FIG. 4, the processor (220) can output an initial screen (400) indicating the connection relationship between multiple devices.

[0062] For example, the processor (220) can output an initial screen (400) indicating the relationship between the solar module (410), the ESS (429), the loads (430), and the grid (440).

[0063] Here, loads (430) may mean devices that consume power, and although only home appliances are shown in the drawing, they are not limited thereto, and may include any equipment, device, component, etc. that consumes power.

[0064] For example, in the case of a home, the processor (220) may output an initial screen including loads (430) such as a microwave oven (430a), a washing machine (430b), an oven (430c), a refrigerator (430d), and a TV (430e). In addition, in the case of a factory, the processor (220) may output an initial screen including industrial equipment, machinery, etc. In addition, in the case of a farm, the processor (220) may output an initial screen (400) including agricultural equipment, agricultural machinery, etc.

[0065] Additionally, the processor (220) can represent a connection relationship between multiple devices using an arbitrary line segment. Here, the arbitrary line segment may correspond to an actual wire through which multiple devices are actually connected.

[0066] For example, the processor (220) can obtain power information for each of the plurality of devices.

[0067] For example, the processor (220) can obtain power information of the solar module (410). Specifically, the processor (220) can obtain information such as the current power generation amount, accumulated power generation amount, and expected power generation amount of the solar module (410). In addition, the processor (220) can obtain information such as the current power generation amount, accumulated power generation amount, and expected power generation amount of each of the plurality of cells included in the solar module (410).

[0068] For example, the processor (220) can obtain power information of the ESS (420). Specifically, the processor (220) can obtain information such as the amount of power stored in the ESS (420) and the expected amount of power stored.

[0069] For example, the processor (220) can obtain power information of the loads (430). Specifically, the processor (220) can obtain information such as the amount of power consumed according to the operation of each load (430).

[0070] For example, the processor (220) can obtain power information of the grid (440). Specifically, the processor (220) can obtain information such as the amount of power that can be transmitted and the amount of power that needs to be received of the grid (440).

[0071] For example, the processor (220) can change and output the initial screen (400) so that the movement of power between multiple devices is expressed in real time based on power information.

[0072] FIG. 5 is a drawing for explaining an example of a method for changing and outputting an initial screen according to one embodiment. FIG. 6 is a drawing for explaining an example of a wire that is changed in an initial screen according to one embodiment.

[0073] Hereinafter, with reference to FIGS. 5 and 6, an example of a processor (220) changing and outputting an initial screen will be described.

[0074] First, referring to FIG. 5, the processor (220) can change and output the initial screen so that the movement of power between multiple devices is expressed in real time based on the amount of power being moved.

[0075] For example, the processor (220) can express the thickness of a wire as thicker as the amount of power transferred increases, and can express the thickness of a wire as thinner as the amount of power transferred decreases. In other words, the processor (220) can output the screen (500) by changing the thickness of the wire in proportion to the actual amount of power transferred.

[0076] Additionally, in the present disclosure, the amount of power may be expressed relatively by the amount of power of each of the plurality of devices output on the screen (500).

[0077] For example, the processor (220) can change the thickness of the wire to the thickest as the amount of power moving from the solar module (510) is the largest. In addition, the processor (220) can change the thickness of the wire as some of the power moving from the solar module (510) moves to the ESS (520) and the remaining part moves to the loads (530) or the grid (540).

[0078] For example, since the amount of power consumed by each load (530) may be different, and accordingly, the amount of power transferred may also be different, the processor (220) may change the thickness of the wire differently depending on the amount of power transferred to each load (530). In addition, if there is a load (530b) among the loads (530) that does not consume power, there may be no power transferred, and thus the processor (220) may represent the wire as a dotted line.

[0079] For example, the processor (220) may indicate the direction of moving power using arrows. In addition, the processor (220) may change the number of arrows, the spacing between arrows, the size of the arrows, etc., depending on the amount of moving power.

[0080] For example, the processor (220) can be changed so that as the amount of power moving increases, the number of arrows increases, the spacing between arrows decreases, and the size of the arrows increases.

[0081] Referring to FIG. 6, the processor (220) can change the wire based on the amount of power being moved.

[0082] For example, the processor (220) can change the thickness of a wire (600a) that moves a relatively large amount of power to be thicker than a wire (600b) that moves a relatively small amount of power, and can change the number of arrows, the spacing between arrows, and even the size of the arrows. In addition, the processor (220) can change a wire (600c) that moves no power to a dotted line.

[0083] Meanwhile, the processor (220) can detect a wire in which an error has occurred and change the shape of the wire in which an error has occurred and output it.

[0084] For example, the processor (220) may set at least one reference point on each of the wires connecting a plurality of devices based on preset criteria, and determine whether at least one of the wires has an abnormality based on power information at the at least one reference point. In addition, the processor (220) may change and output in real time the shape of at least one of the images corresponding to the wires on the initial screen based on the determination result.

[0085] FIG. 7 is a drawing for explaining an example of setting a reference point in a wire according to one embodiment.

[0086] Hereinafter, with reference to FIG. 7, an example of a processor (220) determining a wire with an abnormality by setting a reference point on the wire will be described.

[0087] Referring to FIG. 7, the processor (220) can set at least one of the first reference point (750) or the second reference point (760).

[0088] For example, the processor (220) may set at least one point of the wires connecting the plurality of devices as the first reference point (750). In addition, the processor (220) may set a branch point of the wires connecting the plurality of devices as the second reference point (760). Here, the first reference point (750) may be at least one point between the second reference points (760). In addition, for convenience of explanation, only one first reference point (750) and one second reference point (760) are illustrated in FIG. 7, but it is obvious to those skilled in the art that multiple reference points are set for each.

[0089] For example, the processor (220) can determine whether there is an abnormality in at least one of the wires based on power information at at least one reference point.

[0090] For example, the processor (220) can determine whether a wire is abnormal based on the amount of power at a reference point.

[0091] For example, if the current power amount at a reference point is less than the expected power amount, the processor (220) may determine that there is a problem with the wire. In other words, since the power produced from the solar module (710) may be stored in the ESS (720) or consumed by the loads (730), the amount of power may gradually decrease, and the processor (220) may calculate the expected power amount at each reference point.

[0092] For example, the processor (220) can calculate the expected power amount at each reference point based on the amount of power produced from the solar module (710), the amount of power stored in the ESS (720), and the amount of power consumed by each load (730). In this case, the processor (220) can set the error range of the expected power amount based on the resistance of the wire, weather information, etc.

[0093] For example, the processor (220) may determine that there is a problem with the wire if the current power amount moving from the reference point is less than the calculated expected power amount or if the current power amount is outside the error range of the expected power amount. As another example, the processor (220) may determine that there is no problem with the wire if the current power amount moving from the reference point is within the error range of the expected power amount.

[0094] Additionally, the processor (220) can determine that there is a problem with the wire even if the power amount is not measured at the reference point.

[0095] For example, the processor (220) may change and output in real time the shape of at least one image corresponding to the wires on the initial screen based on the result of determining that there is a problem with the wires. Here, the presence of a problem with the wires may mean that the wires are cut, have a current leak, or are short-circuited. In addition, changing the image corresponding to the wires may include changing the color of the wires, adding new marks to the wires, or splitting a single wire into multiple pieces.

[0096] FIG. 8 is a diagram illustrating an example of changing the shape of an image corresponding to a wire based on a result of determining that there is a problem with the wire according to one embodiment. FIG. 9 is a diagram illustrating another example of changing the shape of an image corresponding to a wire based on a result of determining that there is a problem with the wire according to one embodiment.

[0097] Hereinafter, with reference to FIGS. 8 and 9, examples of the processor (220) changing the shape of an image corresponding to a wire will be described.

[0098] First, referring to FIG. 8, if the processor (220) determines that there is a problem with a wire based on power information at a reference point (850), it can indicate that there is a problem with the wire.

[0099] For example, the processor (220) can output a screen (800) with a new image added to the image corresponding to the wire determined to be abnormal.

[0100] For example, the processor (220) can output a screen (800) in which an image corresponding to a wire determined to be abnormal is changed into a shape of a broken wire.

[0101] Additionally, the processor (220) can notify the user of a problem with a wire, and can also provide information about the wire with the problem. For example, the processor (220) can provide the user with information such as the location of the wire with the problem, the reason for determining the problem, the current power consumption of the wire, and the expected power consumption.

[0102] Referring to FIG. 9, if the amount of power at the reference point (950) is less than or equal to a preset value, the processor (220) determines that there is an abnormality in the wire where the reference point (950) exists and outputs a screen (900) with a changed image shape corresponding to the wires after the wire.

[0103] For example, the processor (220) may determine that a wire is disconnected if the amount of power at the reference point (950) is below a preset value. Accordingly, the processor (220) may output a screen (900) with a changed image shape corresponding to wires through which power cannot flow due to the wire being disconnected.

[0104] For example, the processor (220) can determine that there is an abnormality in the corresponding wire based on power information at the reference point (950), and can change and output in real time the image shape corresponding to the wires to the refrigerator (930d), TV (930e), and grid (940) to which power cannot flow.

[0105] FIG. 10 is a drawing for explaining another example of an initial screen showing the connection relationship of a plurality of devices included in a solar power generation system according to one embodiment.

[0106] Hereinafter, with reference to FIG. 10, another example in which the processor (220) outputs an initial screen showing the connection relationship between multiple devices will be described.

[0107] Referring to FIG. 10, the processor (220) can output an initial screen (1000) indicating the connection relationship between multiple devices.

[0108] For example, the processor (220) can output an initial screen (1000) indicating the connection relationship between the solar module (1010), ESS (1020), load (1030), and grid (1040).

[0109] Additionally, the processor (220) can detect a device with an abnormality based on power information and output a screen with a changed image shape corresponding to the detected device with an abnormality.

[0110] For example, the processor (220) can determine whether there is an abnormality in any one of the plurality of devices based on power information of each of the plurality of devices, and can change and output the shape of at least one of the images corresponding to the plurality of devices in real time on the initial screen based on the determination result.

[0111] Additionally, if the processor (220) determines that at least one of the plurality of devices is abnormal based on the judgment result, it can output status information of the device determined to be abnormal.

[0112] For example, the processor (220) can determine that there is a problem with the solar module (1010) by using the difference between the expected amount of power generated from the solar module (1010) and the actual amount of power transferred from the solar module (1010). In other words, the processor (220) can determine that there is a problem with the solar module (1010) if the difference between the expected amount of power generated from the solar module (1010) and the actual amount of power generated is outside a preset range. Here, the preset range may be -50% to +50% of the expected amount of power generated, but is not limited thereto.

[0113] In addition, the processor (220) can determine that there is a problem with the ESS (1020) by using the expected storage power amount and the actual storage power amount of the ESS (1020). In other words, the processor (220) can determine that there is a problem with the ESS (1020) if the difference between the expected storage power amount and the actual storage power amount of the ESS (1020) is outside a preset range. Here, the preset range may be -50% to +50% of the expected storage power amount, but is not limited thereto.

[0114] In addition, the processor (220) can determine that there is an abnormality in the load (1030) by using the average power consumption and the current power consumption of the load (1030). In other words, the processor (220) can determine that there is an abnormality in the load (1030) if the difference between the average power consumption and the current power consumption of the load (1030) is outside a preset range. Here, the average power consumption may be the average power consumption for 3 days, 7 days, or 30 days based on the present, but is not limited thereto and may be set differently according to the user's selection. Here, the preset range may be -50% to +50% of the average power consumption, but is not limited thereto.

[0115] In addition, the processor (220) can determine that there is an abnormality in the grid (1040) by using the expected transmission and reception power amount and the actual transmission and reception power amount of the grid (1040). In other words, the processor (220) can determine that there is an abnormality in the grid (1040) if the difference between the expected transmission and reception power amount and the actual transmission and reception power amount is outside a preset range. Here, the preset range may be -50% to +50% of the expected transmission and reception power amount, but is not limited thereto.

[0116] For example, the processor (220) may output a screen with a changed image shape corresponding to a device determined to have an abnormality. Specifically, the processor (220) may output a screen with an indication that an abnormality has occurred in the image shape corresponding to the device determined to have an abnormality. In addition, the processor (220) may provide a notification, such as a sound or text message, to the user.

[0117] For example, if the processor (220) determines that at least one of the plurality of devices is abnormal based on the judgment result, it may output status information of the device determined to be abnormal.

[0118] For example, the processor (220) may output power information of a device determined to be abnormal. Specifically, if there is an abnormality in the solar module (1010), the processor (220) may provide a screen to the user that outputs information on the expected power generation amount and the actual power generation amount, if there is an abnormality in the ESS (1020), the expected power storage amount and the actual power storage amount, if there is an abnormality in the load (1030), the average power consumption amount and the current power consumption amount, and if there is an abnormality in the grid (1040), the expected power transmission and reception amount and the actual power transmission and reception amount.

[0119] Additionally, the device determined to be abnormal may include at least one of a plurality of cells included in the solar module.

[0120] For example, the processor (220) may output only an image corresponding to at least one cell determined to be abnormal among images corresponding to a plurality of cells included in a solar module, in a different display.

[0121] FIG. 11 is a drawing for explaining an example in which an image corresponding to a cell determined to be abnormal among images corresponding to a plurality of cells included in a solar module according to one embodiment is displayed differently.

[0122] Hereinafter, with reference to FIG. 11, an example in which a processor (220) displays an image corresponding to a plurality of cells included in a solar module will be described.

[0123] Referring to FIG. 11, the processor (220) can detect a cell (1111) with an abnormality among the cells included in the solar module.

[0124] For example, the processor (220) can detect an abnormal cell (1111) by using the difference between the expected power generation amount and the actual power generation amount of each of the plurality of cells included in the solar module.

[0125] Accordingly, the processor (220) can output a screen (1110) that displays only images corresponding to the abnormal cell (1111) differently.

[0126] As an example, the processor (220) may add an indication of an abnormality to an image corresponding to a cell (1111) with an abnormality. As another example, the processor (220) may change the color of an image corresponding to a cell (1111) with an abnormality.

[0127] As an additional example, the processor (220) can use a sensor to determine whether there is foreign matter in the solar module or cell, and detect a cell (1111) with an abnormality due to foreign matter.

[0128] FIG. 12 is a drawing for explaining an example in which a solar module with an abnormality according to one embodiment is displayed differently from a solar module without an abnormality.

[0129] Hereinafter, an example of displaying an image of a solar module with an abnormality is described with reference to FIG. 12.

[0130] Referring to FIG. 12, the processor (220) can provide a screen (1200) including a plurality of solar modules.

[0131] For example, the processor (220) may provide a user with a screen (1200) displaying images of a plurality of solar modules. In addition, the processor (220) may provide the user with an image (1210) of a solar module determined to be defective among the plurality of solar modules, displayed differently from the remaining solar modules.

[0132] For example, the processor (220) can detect an abnormal solar module by using the difference between the expected power generation amount of the solar module and the actual power generation amount.

[0133] Accordingly, the processor (220) can display only the image (1210) of a solar module with an abnormality among the images of multiple solar modules differently.

[0134] As an example, the processor (220) may add an indication of an abnormality to an image (1210) of a solar module with an abnormality. As another example, the processor (220) may change the color of the image (1210) of a solar module with an abnormality.

[0135] Meanwhile, the above-described method can be written as a program that can be executed on a computer, and can be implemented on a general-purpose digital computer that runs the program using a computer-readable recording medium. In addition, the structure of the data used in the above-described method can be recorded on a computer-readable recording medium through various means. The computer-readable recording medium includes storage media such as magnetic storage media (e.g., ROM, RAM, USB, floppy disk, hard disk, etc.) and optical reading media (e.g., CD-ROM, DVD, etc.).

[0136] Those skilled in the art will appreciate that the present invention can be implemented in modified forms without departing from the essential characteristics of the above-described invention. Therefore, the disclosed methods should be considered illustrative rather than restrictive. The scope of the claims, not the foregoing description, is defined by the scope of the patent, and should be interpreted to encompass all differences within the scope equivalent thereto.
