Description

Solar power plant cost estimation device and method

[0001] The present invention relates to a solar power plant cost estimation device and method capable of estimating the power plant cost of solar lighting and integrated management of the power plant cost of the entire solar lighting system.

[0002] Solar lighting generates electricity during the day using solar panels, which then supply and recharge electricity to a built-in battery or a separate energy station. At night, the lighting function can be performed by receiving electricity from the built-in battery or a separate energy station.

[0003] Korean Patent No. 10-2338515 discloses the features of an artificial intelligence-based solar power generation prediction system.

[0004] The purpose is to provide a solar power plant cost estimation device and method that can estimate the power plant cost of solar lighting and comprehensively manage the power plant cost of the entire solar lighting system.

[0005] According to one aspect, a solar power plant cost estimation device for estimating power plant costs of one or more first solar lights that directly transmit real-time power plant cost information, one or more second solar lights that transmit non-real-time power plant cost information via an external device, and one or more third solar lights that do not transmit power plant cost information may include a communication unit that performs communication with one or more first solar lights and an external device; and a power plant cost estimation unit that estimates power plant costs of one or more second solar lights and one or more third solar lights based on real-time power plant cost information of one or more first solar lights.

[0006] The power plant cost estimation unit can set a first group including a second solar light and a third solar light located within a predetermined distance from each of one or more first solar lights.

[0007] The power plant cost estimation unit can set a second group including third solar lights located within a predetermined distance from each of the second solar lights that are not included in one or more of the first groups of the one or more second solar lights.

[0008] The third solar light included in Group 1 may not be included in Group 2.

[0009] The power generation cost estimation unit can estimate real-time power generation costs of the second solar lighting and the third solar lighting within the same group based on the power generation cost of the first solar lighting included in the first group.

[0010] The power plant cost estimation unit can estimate the real-time power plant cost by reflecting a correction value determined based on the setting parameters of the second solar lighting and the third solar lighting to the power plant cost of the first solar lighting.

[0011] The correction value can be determined based on at least one of the setting parameters: angle, size, installation location and altitude of the solar panel.

[0012] The power generation cost estimation unit can readjust the correction value based on the difference between the estimated real-time power generation cost of the second solar lighting and the non-real-time power generation cost of the second solar lighting received through an external device.

[0013] The power plant cost estimation unit can readjust the correction value according to the cycle in which it receives information on the non-real-time power plant cost of the second solar lighting received through an external device.

[0014] The power generation cost estimation unit can estimate the real-time power generation cost based on the power generation cost of the closest solar light included in the first group located within a predetermined distance from the second solar light of the second group and a correction value determined based on the set parameters of each solar light included in the second group.

[0015] The power generation cost estimation unit can estimate the real-time power generation cost based on the power generation cost of the closest solar light among the solar lights included in one of the first and second groups located within a predetermined distance from each of the third solar lights not included in the first and second groups, and a correction value determined based on the set parameters of each of the third solar lights not included in the first and second groups.

[0016] The power generation cost estimation unit can determine a predetermined distance for grouping based on the difference between the estimated real-time power generation cost of the second solar lighting and the non-real-time power generation cost of the second solar lighting received through an external device.

[0017] The power generation cost estimation unit determines that power generation cost information received from the first solar light included in the first group or the second solar light included in the second group changes by a predetermined threshold or is not received, and can estimate the real-time power generation cost based on the power generation cost of the closest solar light included in the first group or the second group located within a predetermined distance from the first solar light included in the first group or the second group determined to be faulty and a correction value determined based on the set parameters of each solar light included in the second group.

[0018] According to one aspect, a method is provided in a computing device for estimating power generation costs of one or more first solar lights that directly transmit real-time power generation cost information, one or more second solar lights that transmit non-real-time power generation cost information via an external device, and one or more third solar lights that do not transmit power generation cost information, the computing device having one or more processors and a memory storing one or more programs executed by the one or more processors, the method including the steps of: performing communication with one or more first solar lights and an external device; and estimating power generation costs of one or more second solar lights and one or more third solar lights based on the real-time power generation cost information of one or more first solar lights.

[0019] It is possible to implement an integrated control system based on the digital twin concept that can predict the power generation cost of solar lighting and respond to solar lighting that has or may have an abnormality.

[0026] Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings. In describing the present invention, detailed descriptions of known functions or configurations will be omitted if they are deemed to unnecessarily obscure the gist of the present invention. Furthermore, the terms described below are defined based on their functions in the present invention and may vary depending on the intentions or practices of the user or operator. Therefore, their definitions should be based on the overall content of this specification.

[0027] Hereinafter, embodiments of a solar power plant cost estimation device and method are described in detail with reference to drawings.

[0028] Figure 1 is a configuration diagram of a solar power plant cost estimation device according to one embodiment.

[0029] Referring to Fig. 1, a solar power plant cost estimation device (100) may include a communication unit (110) and a power plant cost estimation unit (120). For example, the power plant cost may be a value including at least one of the generation amount and the consumption amount.

[0030] According to one example, the solar power plant cost estimation device (100) can estimate the power plant cost of one or more first solar lights that directly transmit real-time power plant cost information, one or more second solar lights that transmit non-real-time power plant cost information through an external device, and one or more third solar lights that do not transmit power plant cost information.

[0031] According to one embodiment, the communication unit (110) can communicate with one or more directly connected first solar lights and external devices. The communication unit (110) can directly receive real-time power generation cost information from one or more first solar lights. In addition, the communication unit (110) can receive non-real-time power generation cost information of one or more second solar lights through an external device connected to the second solar lights.

[0032] For example, real-time and non-real-time can be determined based on whether the measured time and the received time are within a given delay time. Therefore, real-time can be a characteristic that has a given delay time.

[0033] For example, the communication unit (110) may receive real-time power generation cost information from the first solar light. At this time, the first solar light may continuously transmit the real-time power generation cost information or periodically transmit the real-time power generation cost information according to a predetermined cycle. Here, continuous or periodic may be determined depending on whether the power generation cost measured within the first solar light is measured continuously or periodically.

[0034] For example, the communication unit (110) may receive non-real-time power plant cost information from an external device connected to the second solar light. At this time, the external device may transmit the power plant cost information received from the second solar light with a predetermined delay time, or may transmit the power plant cost information after accumulating it for a predetermined period of time.

[0035] For example, the first solar light may include a real-time power generation cost measurement device. The first solar light may be directly connected to the solar power generation cost estimation device via optical communication, etc., and the power generation cost of the installed solar light may be measured in real time and transmitted to the solar power generation cost estimation device.

[0036] For example, the second solar light may include a metering device. The metering device is a meter installed and managed by an external device that is linked to the solar power plant cost estimation device. The measured values ​​of the meter are collected by the external device, and the solar power plant cost estimation device can separately obtain them. Here, the external device may be a database operated by a power system operator such as Korea Electric Power Corporation. Accordingly, the solar power plant cost estimation device cannot obtain real-time information from the second solar light. For example, if a real-time power plant cost measurement device and a metering device are installed at the same time, it can be classified as the first solar light.

[0037] For example, a third solar light is a lighting device that does not have a separate power plant cost measuring device attached.

[0038] According to one embodiment, the power generation cost estimation unit (120) can estimate the power generation cost of one or more second solar lights and one or more third solar lights based on real-time power generation cost information of one or more first solar lights. For example, the power generation cost estimation unit (120) can group solar lights within a predetermined distance from the first solar light, and estimate the real-time power generation cost of solar lights included in the same group.

[0039] According to one embodiment, the power plant cost estimation unit (120) can set a first group including a second solar light and a third solar light located within a predetermined distance from each of one or more first solar lights.

[0040] Referring to FIG. 2, the power generation cost estimation unit (120) can group the second solar lights and the third solar lights located within a predetermined distance from the first solar lighting device into one group. For example, if there are three first solar lighting devices, the power generation cost estimation unit (120) can set three first groups (21, 220, 230).

[0041] According to one embodiment, the power generation cost estimation unit (120) can estimate the real-time power generation costs of the second solar light and the third solar light within the same group based on the power generation cost of the first solar light included in the first group. For example, the power generation cost estimation unit (120) can estimate the real-time power generation costs of the second solar light (212, 213) and the third solar light (not shown) included in the first group (210) based on the power generation cost of the first solar light (211) included in the first group (210).

[0042] For example, the power generation cost estimation unit (120) can estimate the power generation cost of solar lighting within the same group to be the same as the power generation cost of the first solar lighting that serves as the standard for the group.

[0043] According to one embodiment, the power generation cost estimation unit (120) can estimate the real-time power generation cost by reflecting a correction value determined based on the setting parameters of the second and third solar lights to the power generation cost of the first solar light. For example, the correction value can be determined based on at least one of the setting parameters, such as the angle, size, installation location, and altitude of the solar panel. The setting parameters can be metadata about the installed status of each solar light, and can be parameters for factors that can cause a difference in the amount of solar light received by each area depending on the season or time zone, such as the angle, size, installation location, and altitude of the solar panel. In other words, it can be the values ​​of variables that cause a difference in the amount of sunlight incident in the same situation. The degree to which each parameter affects the amount of sunlight incident by time zone (weight) can be set in advance and stored.

[0044] For example, the power generation cost estimation unit (120) can receive power generation information at a specific time from the real-time power generation cost measuring device of the first solar light (211). For example, the current power generation of the first solar light can be measured and transmitted as 50 Wh. In this case, the power generation cost estimation unit (120) can tentatively set the power generation for the solar lights (212, 213) included in the same first group to 50 Wh.

[0045] For example, the power generation cost estimation unit (120) can estimate the difference in power generation caused by the difference in the set parameters by comparing the set parameters of the first solar light (211) with the set parameters of other solar lights (212, 213) included in the same group. For example, if the panel size of the solar light (212, 213) is half of that of the first solar light (211), the power generation cost estimation unit (120) can estimate that the incident amount of the two solar lights is half of that of the first solar light (211) and set the correction value to 0.5. In this case, the power generation cost estimation unit (120) can estimate the power generation of the solar lights (212, 213) by reflecting the correction value 0.5 to the current power generation amount of 50Wh of the first solar light (211), such as '0.5 x 50Wh = 25Wh'.

[0046] According to one embodiment, the power generation cost estimation unit (120) can readjust the correction value based on the difference between the estimated real-time power generation cost of the second solar lighting and the non-real-time power generation cost of the second solar lighting received through an external device. For example, the correction value may need to be readjusted due to factors such as the condition of the solar lighting, weather, etc. The power generation cost estimation unit (120) can readjust the correction value by comparing the power generation cost estimated in real time with the actually measured non-real-time power generation cost.

[0047] For example, if the second solar light is included in the first group, the power generation cost estimation unit (120) can receive power generation cost information for the second solar light in non-real time. At this time, the power generation cost estimation unit (120) can refer to the measurement time of the acquired meter data to check the estimated power generation cost value that was estimated and calculated for the second solar light at the corresponding measurement time, and can reflect the difference between the estimated power generation cost and the estimated power generation cost value acquired from an external device in the estimated power generation cost value within the group. For example, if the power generation amount is estimated to be 70Wh at 1 PM for a specific second solar light, and the meter data installed on the specific second solar light is acquired as 65Wh at 2 PM, the power generation cost estimation unit (120) can perform additional correction by continuously deducting 5Wh from the estimated calculated value of the group that includes the specific second solar light from 2 PM until the next data acquisition.

[0048] For example, if there are two or more second solar lights in the same group, the power generation cost estimation unit (120) can readjust the correction value individually for each one or readjust the correction value using the average of the difference values ​​of the two or more second solar lights. Furthermore, the power generation cost estimation unit (120) can reflect the readjusted correction value in estimating the power generation cost of the third solar light. At this time, the power generation cost estimation unit (120) can readjust the correction value of the third solar light based on the correction value readjustment information of the second solar light nearby for each of the third solar lights, readjust the correction value, or readjust the correction value using the readjustment average information within the group.

[0049] According to one embodiment, the power generation cost estimation unit (120) may readjust the correction value according to the cycle in which the information on the non-real-time power generation cost of the second solar lighting is received through an external device. For example, if the information on the non-real-time power generation cost of the second solar lighting is received every hour, the power generation cost estimation unit (120) may readjust the correction value every hour.

[0050] According to one embodiment, the power plant cost estimation unit (120) can set a second group including third solar lights located within a predetermined distance from each of the second solar lights that are not included in one or more of the first groups of one or more second solar lights.

[0051] Referring to FIG. 3, the power generation cost estimation unit (120) can create a second group centered around each of the two second solar lights (311, 312) that are not included in the first group. For example, the power generation cost estimation unit (120) can create a second group that includes the second solar light (311) and the third solar light (312) located within a predetermined distance.

[0052] In one embodiment, the power plant cost estimation unit (120) may not include the third solar light included in the first group in the second group. For example, in the case of the second solar light (321), there is one third solar light (233) within a predetermined range, but since the third solar light is included in the first group (230), the power plant cost estimation unit (120) does not include it in the second group.

[0053] According to one embodiment, the power plant cost estimation unit (120) can estimate the real-time power plant cost based on the power plant cost of the closest solar light included in the first group located within a predetermined distance from the second solar light of the second group and a correction value determined based on the set parameters of each solar light included in the second group.

[0054] For example, the power generation cost estimation unit (120) can estimate the real-time power generation cost based on the real-time power generation cost of the closest solar light (223) among the solar lights included in the first group located within a predetermined range based on the second solar light (311) included in the second group (310). For example, the power generation cost estimation unit (120) can estimate the real-time power generation cost of the solar lights (311, 312) within the group by applying a correction value determined based on the set parameters of each solar light included in the second group based on the real-time power generation cost of the solar light (223).

[0055] As another example, the power generation cost estimation unit (120) can estimate the real-time power generation cost based on the real-time power generation cost of the closest solar light (213) among the solar lights included in the first group located within a predetermined range based on any one solar light (312) included in the second group (310). For example, the power generation cost estimation unit (120) can estimate the real-time power generation cost of the solar lights (311, 312) within the group by applying a correction value determined based on the set parameters of each solar light included in the second group based on the real-time power generation cost of the solar light (213).

[0056] For example, the power generation cost estimation unit (120) can readjust the correction value based on the difference between the estimated real-time power generation cost of the second solar lighting and the non-real-time power generation cost of the second solar lighting received through an external device. For example, the power generation cost estimation unit (120) can readjust the correction value by comparing the estimated real-time power generation cost of the second solar lighting (311) belonging to the second group with the measured non-real-time power generation cost of the second solar lighting (311) received through an external device.

[0057] According to one embodiment, the power generation cost estimation unit (120) can estimate the real-time power generation cost based on the power generation cost of the closest solar light among the solar lights included in one of the first and second groups located within a predetermined distance from each of the third solar lights not included in the first and second groups, and a correction value determined based on the set parameters of each of the third solar lights not included in the first and second groups.

[0058] Referring to Fig. 4, three third solar lights (411, 412, 421) may not be included in the first and second groups. The power generation cost estimation unit (120) may create a third group of third solar lights that are not included in the first and second groups. At this time, the power generation cost estimation unit (120) may group the third groups according to predetermined conditions to estimate the real-time power generation cost, or estimate the real-time power generation cost individually without grouping.

[0059] For example, the power generation cost estimation unit (120) can estimate the real-time power generation cost by grouping two third solar lights (411, 412) into a third group. For example, the power generation cost estimation unit (120) can estimate the real-time power generation cost based on the real-time power generation cost of the closest solar light among the solar lights included in the first group or the second group located within a predetermined distance based on any one of the third solar lights belonging to the third group. For example, in the case of the third group (410), the power generation cost estimation unit (120) can estimate the real-time power generation cost based on the real-time power generation cost of the solar light (222) of the first group located within a predetermined distance based on the third solar light (411) included in the group. That is, the power plant cost estimation unit (120) can estimate the real-time power plant cost based on the correction value determined based on the set parameters of each of the third solar lights (411, 412) and the real-time power plant cost of the solar light (222).

[0060] As another example, if there are no first and second groups within a predetermined distance, the power generation cost estimation unit (120) can estimate the real-time power generation cost based on the real-time power generation cost of the third solar light within a predetermined distance that is not included in the first and second groups. For example, assuming that the third solar light (411, 412) is not a group, the first and second groups may not be located within the predetermined distance of the third solar light (412). In this case, the power generation cost estimation unit (120) can estimate the real-time power generation cost of the third solar light (411) located within the predetermined distance and then estimate the real-time power generation cost of the third solar light (412).

[0061] According to one embodiment, the power generation cost estimation unit (120) may determine a predetermined distance for grouping based on the difference between the estimated real-time power generation cost of the second solar lighting and the non-real-time power generation cost of the second solar lighting received through an external device. For example, the solar lighting located at the edge of the first group may have different irradiance conditions from the first solar lighting at the center. In this case, there may be a large difference between the estimated real-time power generation cost and the actual real-time power generation cost. Accordingly, the power generation cost estimation unit (120) may reduce the size of the first group by reducing the predetermined distance when the difference between the estimated real-time power generation cost of the second solar lighting and the non-real-time power generation cost of the second solar lighting received through an external device exceeds a predetermined range.

[0062] For example, the power generation cost estimation unit (120) can set multiple predetermined distances for group setting and estimate the power generation cost for each scenario. Thereafter, when the metering device data for the second solar lighting is acquired, the power generation cost estimation unit (120) can calculate the difference between the power generation cost estimated for each scenario for the second solar lighting device for which the metering device data was acquired and the non-real-time power generation cost of the corresponding second solar lighting, and estimate the power generation cost by selecting the predetermined distance that appears to be more accurate as a base for a certain period of time. In addition, the power generation cost estimation unit (120) can re-execute the scenario after a certain period of time has elapsed and re-determine the predetermined distance.

[0063] According to one embodiment, the power generation cost estimation unit (120) determines a failure if the power generation cost information received from the first solar light included in the first group or the second solar light included in the second group changes by a predetermined threshold or is not received, and estimates the real-time power generation cost based on the power generation cost of the closest solar light included in the first group or the second group located within a predetermined distance from the first solar light included in the first group or the second group determined to be a failure and a correction value determined based on the set parameters of each of the solar lights included in the second group.

[0064] For example, the power generation cost estimation unit (120) may determine that a failure has occurred in the real-time power generation cost measurement unit of the first solar light when a numerical value obtained from the real-time power generation cost measurement unit of the first solar light changes by a predetermined threshold or more at a first specific point in time or when a measured value is confirmed not to be obtained. Thereafter, the power generation cost estimation unit (120) may check a value measured at a predetermined time point before the first specific point in time for the first group including the first solar light at the first specific point in time, and estimate the power generation cost for the first group based on this to perform failure response control.

[0065] For example, the power plant cost estimation unit (120) may determine that a failure has occurred if data is not acquired even though a second specific point in time has passed, which is a point in time when the metering device data is expected to be acquired for the second solar light. Thereafter, the power plant cost estimation unit (120) may check the value measured at a predetermined time before the second specific point in time for the second group including the second solar light at the second specific point in time, and estimate the power plant cost for the second group based on this, thereby performing failure response control.

[0066] For example, the power plant cost estimation unit (120) can estimate the power plant cost by treating the first solar light or the second solar light that is judged to be faulty as the third solar light that does not have a separate device installed from the first specific time or the second specific time.

[0067] For example, if there are multiple first solar lights and multiple first groups are formed, the power generation cost estimation unit (120) can obtain and correct the power generation cost measurement value of the other first group located closest to the first group including the first solar light expected to fail, and estimate the power generation cost after a specific point in time. As another example, if there is no other first group within a predetermined distance, the power generation cost estimation unit (120) can refer to the past measurement history data of the first solar light expected to fail, and replace the measurement value of a specific past date with the most similar weather conditions and measurement time within a predetermined period with the measurement value after a specific point in time.

[0068] For example, as shown in FIG. 5, a solar light may include a solar panel, LED lighting, and a battery. As another example, as shown in FIG. 6, the solar light may be connected to a separate energy station installed externally, and may charge the energy station or use the energy station's power depending on the power generation capacity.

[0069] Figure 7 illustrates an example of an energy station and device that can be operated in conjunction with solar lighting. For example, a robotic mower, charged at an energy station powered by solar power, can manage lawns during off-peak hours. In this case, all control is AI-based, with the energy station overseeing the robotic mowers. For example, the robotic mowers can manage lawns in each area according to the energy station's instructions, collecting lawn condition data and transmitting it to the energy station.

[0070] Figure 8 is a flowchart illustrating a method for estimating solar power plant capacity according to one embodiment.

[0071] According to one embodiment, a solar power plant cost estimation device may be a computing device having one or more processors and a memory storing one or more programs executed by the one or more processors, and estimating the power plant cost of one or more first solar lights that directly transmit real-time power plant cost information, one or more second solar lights that transmit non-real-time power plant cost information through an external device, and one or more third solar lights that do not transmit power plant cost information.

[0072] According to one embodiment, a solar power plant cost estimation device can communicate with one or more first solar lights and an external device (810), and can estimate the power plant cost of one or more second solar lights and one or more third solar lights based on real-time power plant cost information of one or more first solar lights (820).
