Description

Agricultural solar power smart farm complex system

[0001] The present invention relates to an agricultural solar power smart farm complex system capable of agriculture. More specifically, it relates to an agricultural solar power smart farm complex system configured in the form of a solar greenhouse or open-field solar power to enable agriculture, and to enable checking the status of solar power generation facilities and smart farms anytime and anywhere, and immediately resolving any problems that arise remotely.

[0002] Electricity generation using solar panels is attracting attention as a new energy source, but solar panels require a significant area for installation, making it burdensome to install them while damaging farmland or forests. In addition, even when installed on water surfaces or covering the tops of crops, the desired power generation is achieved while minimizing damage to the natural environment. At the same time, solar panels are installed on roofs to avoid restrictions on installation locations.

[0003] The method of installing solar panels on open or closed roofs is to install a separate structure on the upper side of the roof to fix the solar panels. After installing the roof with the exterior material that makes up the roof, a frame is fixed to the upper side of the roof, and then the solar panels are installed using the frame.

[0004] Therefore, since solar panels installed on the roof cannot be used as building materials and are installed separately on the upper side of the roof component, solar panels cannot be used as building exterior materials. Therefore, in order to use solar panels as roof components, the watertightness of the roof component, the wind load resistance for the exterior material, and the simplicity of installation and maintenance of solar panels or array configuration must all be satisfied at the same time, and the existing roof component installation part and the aesthetic and functional characteristics must not be significantly changed.

[0005] Meanwhile, the solar power generation market has continued to grow based on the greenhouse gas reduction regime stipulated in Article 17 of the Kyoto Protocol. In Korea, this growth has continued since the "Act on Allocation and Trading of Greenhouse Gas Emissions" went into effect in 2015 pursuant to Article 46 of the "Framework Act on Low Carbon, Green Growth." Due to this continued market growth, global solar power installations are estimated to reach approximately 120 GW by 2020.

[0006] Based on domestic REC issuance, installations in the first quarter of 2020 reached 116 GW, an 89% increase year-on-year, demonstrating continued expansion. By capacity, installations reached 377 MW (under 100 kW), 602 MW (100 kW to 1 MW), and 182 MW (1 MW or more), indicating that installations are primarily occurring at mid- to large-scale solar power plants.

[0007] As the solar power generation market grows, power plants have traditionally been built with a focus on generating capacity. However, the need for remote monitoring is increasing to efficiently manage the growing number of solar power plants. Consequently, the market for new power plants capable of remote monitoring and the introduction of remote monitoring systems to existing plants is also expected to grow in parallel.

[0008] Previously, small and medium-sized solar power plants were rarely built to enable remote monitoring, or only minimal data could be monitored. Solar power plants are equipped with not only solar panels but also inverters, various equipment to protect the power system, power meters to measure generated power, energy storage systems (ESS) to store generated electrical energy, and sensors to detect environmental changes around the power plant. Traditionally, data acquisition from these facilities involved establishing an RS-485-based power plant communication network with an RTU (Remote Terminal Unit) and transmitting it to the power plant operator's computer.

[0009] However, this method has the problem that it only increases the management points of solar power generation facilities (management of communication equipment in addition to power generation facilities) and has a limited effect on improving facility management efficiency.

[0010] Additionally, solar power plant facilities are composed of equipment of various types and manufacturers, and each has different communication protocols, making remote monitoring and remote control difficult.

[0011] Meanwhile, as the era of climate crisis unfolds, the agricultural sector is the most sensitive, as it is directly affected by weather and climate change, such as droughts, floods, and typhoons.

[0012] Meanwhile, agriculture is also developing new systems that combine digital, bio, and energy to address the fundamental issues of agriculture in the era of climate crisis. Smart solar greenhouses and smart agricultural solar systems that combine digital, bio, and energy systems are being developed.

[0013] The present invention is a technology devised to solve the problems of the above-described prior art, and the conventional agricultural solar power system has a complicated structure for installing solar panels separately from the installation of roof components, has a problem of water leakage between solar panels, and is composed of equipment of various types and manufacturers, which causes problems of difficulty in remote monitoring and remote control. Therefore, the main purpose of the present invention is to provide an agricultural solar power smart farm complex system that is configured in the form of a solar greenhouse or open-field solar power to enable farming, and to check the status of solar power generation facilities and smart farm facilities anytime and anywhere, and to immediately resolve problems remotely when they occur.

[0094] <Example 1>

[0095] Embodiment 1 of the present invention is configured in the form of a solar greenhouse, and will be described in detail below with reference to drawings 1 to 10.

[0096] The structure (100), which is the main component of the present invention, is installed so that an internal space is formed. Since any type of steel having a cross-section used in the past may be used, a detailed description thereof will be omitted, and it is installed so that an internal space in which crops can be grown is formed.

[0097] The main component of the present invention, the longitudinal drainage channel (200), is installed in the front-back direction on the upper part of the structure (100), and a plurality of drainage channels are installed at regular intervals in the left-right direction. The drainage channel (200) is made of a "C" shaped steel with an open upper part, and is configured to allow rainwater to flow. The length is formed in the front-back direction, i.e., the longitudinal direction, according to the shape of the upper part of the structure (100), and rainwater moving to the transverse drainage channel (300), which will be described in detail later, is collected and flows.

As sunlight is refracted and scattered, it overlaps and is amplified, thereby illuminating the internal space of the structure (100), thereby minimizing shade and enabling the cultivation of crops even when a solar module (400), which will be described in detail later, is installed on the upper part of the structure (100).

[0102] The horizontal drain (300) of the present invention is configured to include a plurality of through holes (not shown in the drawing) formed through which the PET light-emitting body (310) can be installed, and the PET light-emitting body (310) is preferably installed so that it is fitted into the through hole (302), fixed, and then formed into an airtight seal between itself and the through hole (302) through an airtight material such as silicone. At this time, any structure used in the related art may be used for the structure in which the PET light-emitting body (310) is fixed to the through hole of the horizontal drain (300), and therefore, a detailed description thereof will be omitted.

[0103] The solar module (400), which is the main component of the present invention, is installed on the upper part of a pair of adjacent horizontal drains (300) among a plurality of horizontal drains (300), and is installed so that the front end and the rear end are positioned on the upper part of the horizontal drains (300), so that rainwater moves along the upper surface to the horizontal drain (300) or the vertical drain (200).

[0104] The solar module (400) of the present invention is configured to include a solar frame (not shown in the drawing) and a solar panel (not shown in the drawing) installed on the upper part of the solar frame.

[0105] The solar module (400) of the present invention, that is, the solar frame, is configured to include a first panel flange (410) that protrudes rearwardly at the front lower portion and is positioned below the second drainage flange (330) of the horizontal drainage channel (300), and a second panel flange (420) that protrudes forwardly at the rear lower portion and is positioned below the first drainage flange (320) of the horizontal drainage channel (300).

[0106] At this time, the solar frame is configured to include an extension portion (not shown in the drawing) that protrudes downward at the front lower portion and the rear lower portion so that the first panel flange (410) and the second panel flange (420) can be positioned at the lower portion of the second drainage flange (330) or the first drainage flange (320).

[0107] That is, the extension portion protrudes rearward and forward, respectively, after the first panel flange (410) and the second panel flange (420) are spaced apart in the downward direction, so that the first panel flange (410) and the second panel flange (420) are positioned below the second drainage flange (330) or the first drainage flange (320), thereby allowing the solar module (400) of the present invention to be installed on the upper portion of the horizontal drainage channel (300).

[0108] At this time, the solar module (400) of the present invention is installed at the upper rear portion of the transverse drain (300) located at the front among a pair of transverse drains (300) adjacent to the front, and is installed at the upper front portion of the transverse drain (300) located at the rear among a pair of transverse drains (300) adjacent to the rear, thereby allowing rainwater on the surface to move to the transverse drain (300).

[0109] The fixing member (500), which is a main component of the present invention, fixes the front or rear of the horizontal drain (300) and the solar module (400), and a plurality of fixing members are installed on the upper portion of the horizontal drain (300) so that the solar module (400) can be stably and firmly fixed.

[0110] Specifically, the fixing member (500) of the present invention is configured to include a pair of hooks (510) that are coupled so that the first drainage flange (320) or the second drainage flange (330) is positioned on the upper inner side, and the upper surface (512) is in close contact with the second panel flange (420) or the first panel flange (410) to press and fix the first panel flange, a fixing plate (520) positioned at the lower part of the horizontal drainage channel (300) and having the lower part of the pair of hooks (510) penetrated therethrough, and a fixing bolt (530) positioned at the lower part of the fixing plate (520) and screwed to the lower part of the hook (510).

[0111] That is, when the fixing member (500) of the present invention is installed so that the first panel flange (410) or the second panel flange (420) of the solar module (400) is positioned at the lower part of the second drainage flange (330) or the first drainage flange (320) of the horizontal drainage channel (300), a pair of hooks (510) are installed on the upper inner side of the hooks (510) so that the second drainage flange (330) or the first drainage flange (320) is positioned, and after the fixing plate (520) is positioned at the lower part of the horizontal drainage channel (300) so that the lower part of the pair of hooks (510) penetrates, the hook (510) is pressed downward through the fixing bolt (530), so that the upper surface (512) of the hook (510) is The second panel flange (420) or the first panel flange (410) of the solar module (400) is pressed so that the solar module (400) can be stably and firmly fixed to the horizontal drain (300).

[0112] In addition, the fixing member (500) of the present invention is configured to include a packing (540) provided on the upper inner side of the hook (510), and the packing (540) prevents damage to the first drainage flange (320) or the second drainage flange (330) when the upper surface of the hook (510) presses the first panel flange (410) or the second panel flange (420) of the solar module (400), and realizes the effect of maintaining a more stably installed state.

[0113] In addition, the fixing member (500) of the present invention is configured to include a buffer spring (550) that is installed on the lower outer periphery of the hook (510) and is positioned between the fixing plate (520) and the fixing bolt (530).

[0114] The above-mentioned buffer spring (550) not only prevents damage to the hook (510) when the hook (510) is pressed downward through the fixing bolt (530), but also enables the first panel flange (410) or the second panel flange (420) of the solar module (400) to be pressed more stably by the hook (510), thereby realizing the effect of allowing the solar module (400) to be firmly fixed to the horizontal drain (300).

[0115] In addition, the above-mentioned buffer spring (550) causes a buffering effect on the hook (510), thereby minimizing damage to the solar module (400) due to impacts such as strong winds or earthquakes.

[0116] At this time, the buffer spring (550) is characterized by having greater elasticity than the packing (540), so that the pressure of the first panel flange (410) or the second panel flange (420) of the solar module (400) by the hook (510) can be stably and firmly applied, and at the same time, the pressure of the hook (510) can be easily adjusted, so that the solar module (400) can be more easily and stably and firmly fixed to the horizontal drain (300).

[0117] The first blocking member (600), which is a main component of the present invention, is coupled between a pair of solar modules (400) that are adjacent in the left-right direction among a plurality of solar modules (400), is made of an elastic synthetic resin material, and minimizes the space created between the pair of solar modules (400) that are adjacent in the left-right direction, thereby increasing the greenhouse effect.

[0118] Specifically, the first blocking member (600) is configured to include a lower body (610) positioned between a pair of solar modules (400) adjacent left and right, with one upper surface and the other upper surface being in close contact with the lower surface of the solar modules (400), and a lower elastic coupling protrusion (611) protrudingly formed on the upper surface positioned between the pair of solar modules (400) adjacent left and right, and an upper body (620) positioned between a pair of solar modules (400) adjacent left and right, with one lower surface and the other lower surface being in close contact with the upper surface of the solar modules (400), and an upper elastic coupling protrusion (621) protrudingly formed on the lower surface positioned between the pair of solar modules (400) adjacent left and right, and coupled with the lower elastic coupling protrusion (611).

[0119] The lower elastic coupling protrusion (611) is formed to have a length so that elastic force can be generated laterally, and a lower catch protrusion (not shown in the drawing) is formed on the upper inner surface, and the upper elastic coupling protrusion (621) is formed to have a length so that elastic force can be generated laterally, and an upper catch protrusion (not shown in the drawing) is formed on the lower inner surface to correspond to the lower catch protrusion and has an upper surface that catches on the lower surface of the lower catch protrusion.

[0120] That is, the first blocking member (600) of the present invention minimizes rainwater from flowing into the space between a pair of solar modules (400) adjacent left and right and penetrating into the internal space of the structure (100) by connecting the lower body (610) and the upper body (620) by the lower elastic coupling protrusion (611) and the upper elastic coupling protrusion (621), and also minimizes the inflow of outside air, thereby allowing a greenhouse effect to occur.

[0121] In connection with the above, the upper body (620) is configured to include an upper buffer portion (622) that is formed by protruding in a curved shape on one side and the other side to form an upper buffer space (622a) on the inside, so that when the solar module (400) moves due to a strong wind or an earthquake, a buffering force is generated in the upper buffer portion (622), thereby minimizing damage to the first blocking member (600).

[0122] In addition, the upper body (620) and the upper buffer portion (622) are each configured to include an inner reinforcing projection (623) that protrudes inwardly on the lower inner surface, so that the solar module (400) can be installed more closely to the upper surface by the inner reinforcing projection (623) and can be stably installed, while at the same time, the effect of improving durability can be obtained.

[0123] In addition, the upper buffer portion (622) is configured to include a plurality of upper reinforcing protrusions (624) formed longitudinally on the upper surface, and the upper reinforcing protrusions (624) enhance the durability of the upper buffer portion (622) to minimize damage to the upper buffer portion (622) when buffering.

[0124] The lower body (610) is configured to include a lower buffer space (612) formed on one side and the other side, a lower buffer connection part (613) formed to protrude from the lower part of one side and the other side and then bent upward, and a lower buffer part (614) formed to protrude from the upper end of the lower buffer part (614) in one or the other direction so that the upper surface is in close contact with the lower surface of the solar module (400).

[0125] The lower buffer space (612) not only realizes the weight reduction of the lower body (610), but also generates a buffering force on the upper surface to minimize damage, and the lower buffer portion (614) is not only formed to be spaced outward by the lower buffer connecting portion (613), but also generates a buffering force to minimize damage, and maintains a state of stable close contact with the lower surface of the solar module (400), thereby realizing the effect of maintaining a state in which the first blocking member (600) is stably and firmly installed between a pair of adjacent solar modules (400).

[0126] In addition, the upper body (620) and the lower body (610) are configured to include a plurality of grooves (not shown in the drawing) formed on the lower surface and the upper surface, respectively. The grooves not only allow the upper body (620) and the lower body (610) to remain stably installed on the upper surface and the lower surface of the solar module (400), respectively, but also allow a more flexible buffering force to be generated, thereby minimizing damage caused by strong winds or earthquakes.

[0127] The second blocking member (700), which is a main component of the present invention, is coupled to one side or the other side of a solar module (400) located at the edge, and, like the first blocking member (600), is made of a synthetic resin material having elasticity, and protects the outside of the solar module (400) located at the edge while minimizing the space between it and the drainage ditch (200), thereby increasing the greenhouse effect.

[0128] Specifically, the second blocking member (700) is configured to include a lower body (610) positioned on the outside of a solar module (400) located at an edge, with one upper surface or the other upper surface in close contact with the lower surface of the solar module (400), and a lower elastic coupling protrusion (611) protrudingly formed on the upper surface located on the outside of the solar module (400) located at the edge, and an upper body (620) positioned on the outside of the solar module (400) located at an edge, with one lower surface or the other lower surface in close contact with the upper surface of the solar module (400), and an upper elastic coupling protrusion (621) protrudingly formed on the lower surface located on the outside of the solar module (400) located at the edge to be coupled with the lower elastic coupling protrusion (611).

[0129] That is, since the second blocking member (700) of the present invention has the same configuration as the first blocking member (600) described above only on one or the other side, detailed descriptions of the lower elastic coupling protrusion (611), the upper elastic coupling protrusion (621), the upper buffer portion (622), the lower buffer space, the lower buffer connection portion (613), the lower buffer portion (614), etc. will be omitted.

[0130] In addition, the present invention can install an additional sealing member (not shown in the drawing) in a gap to further increase the greenhouse effect. The gap corresponds to the gap between the drainage channel (200) and the second blocking member (700) in the case of a solar module (400) located at the edge, and the gap corresponds to the gap between the first blocking member (600) and the drainage channel (200) in the case of a solar module (400) adjacent to another solar module (400) on the inside. It will be apparent that the additional sealing member is manufactured and installed in a shape corresponding to the gap as described above.

[0131] <Example 2>

[0132] Embodiment 2 of the present invention is configured in the form of an open-air solar power plant, and will be described in detail below with reference to drawings 11 to 14.

[0133] The structure (100), which is the main component of the present invention, is installed at a distance that allows entry and exit of agricultural machinery and work. Pillars (not shown in the drawing) are installed at a certain distance on the ground, and a distance is formed between the pillars so that agricultural machinery such as tractors can enter and exit in all directions.

[0134] The above column fixes a horizontal structure (not shown in the drawing) to the upper side, and the column and the horizontal structure are configured to have a cube shape and are connected in all directions to form a structure, and the column and the horizontal structure form a space inside so that water or pesticide can flow, and a base cap (not shown in the drawing) is fitted to the bottom of the column to prevent water from leaking, and the connecting part where the column and the horizontal structure are connected is fitted using a joint (not shown in the drawing) that connects in three or four directions, so that water and pesticides that have flowed in inside by using the column and the horizontal structure as pipes do not leak out, and spray nozzles (not shown in the drawing) are installed at regular intervals on the bottom of the horizontal structure and the inside of the column, so that water and pesticides are sprayed through the spray nozzles using the column and the horizontal structure as pipes and sprayed on crops.

[0135] The above spray nozzle is not only installed on a horizontal structure, but is also installed on the inside of a pillar, so that water or pesticide can be sprayed from the pillar as well, and water or pesticide that is pressurized from the outside using a pump or the like can be supplied to the inside of the pillar.

[0136] That is, when water or pesticide is supplied to the interior of the column when necessary, the water or pesticide flows through the column and horizontal structure as pipes, and is sprayed from the spray nozzle, so there is no need to install a separate pipe to supply water or pesticide.

[0137] The transverse support (800), which is the main component of the present invention, is installed in the left-right direction on the upper part of the structure (100), and a plurality of the horizontal support members are installed at regular intervals in the front-back direction, so that a plurality of module supports (900), which will be described in detail later, can be installed in the left-right direction.

[0138] The module support (900), which is a main component of the present invention, is installed in a plurality of pieces, each of which is connected at the front and rear to the upper portion of a pair of adjacent horizontal supports (800) among a plurality of horizontal supports (800), spaced apart from each other by a certain distance in the left and right directions, and is made of a "C"-shaped steel with an open upper portion, so that rainwater flowing along the solar modules (400), which will be described in detail later, can be collected and drained, thereby minimizing the impact of excessive rainwater on crops.

[0139] At this time, the module holder (900) of the present invention is configured to include a first holder flange (910) formed to protrude from one side of the upper portion and a second holder flange (920) formed to protrude from one side of the upper portion, and the other side of one solar module (400) to be described in detail later is coupled to one side of the upper portion, and one side of another solar module (400) located on the other side of one of the solar modules (400) is coupled to the other side of the upper portion.

[0140] In addition, the module stand (900) of the present invention is configured to include an eaves (930) made of a "C"-shaped steel that is connected to the front and has an open upper portion, and the eaves (930) allow rainwater flowing along the module stand (900) and rainwater flowing along the solar modules (400), which will be described in detail later, to be collected and moved.

[0141] The above eaves (930) are formed at the front ends of each of a pair of adjacent module supports (900), and the pair of adjacent module supports (900) can be configured to include a connecting eaves (not shown in the drawing) connecting each of the eaves (930), and the connecting eaves allow rainwater to move and drain.

[0142] At this time, the eaves (930) are configured to include a plurality of PET light-emitting bodies (310) installed in the front, which allow sunlight to shine into the shade through the PET light-emitting bodies (310), thereby enabling crop cultivation. A specific description of the PET light-emitting bodies (310) will be based on the description in Example 1.

[0143] The solar module (400), which is the main component of the present invention, is installed on the upper part of a pair of adjacent module stands (900) among a plurality of module stands (900), and is installed so that one end and the other end are positioned on the upper part of the module stands (900), so that rainwater moves along the upper surface to the module stands (900) or the eaves (930).

[0144] The solar module (400) of the present invention is configured, similarly to Example 1, to include a solar frame (not shown in the drawing) and a solar panel (not shown in the drawing) installed on the upper part of the solar frame.

[0145] The solar module (400) of the present invention, that is, the solar frame, is configured to include a first panel flange (410) that protrudes from one side to the other side and is positioned below the second mounting flange (920), and a second panel flange (420) that protrudes from the other side to one side and is positioned below the first mounting flange (910).

[0146] At this time, the solar frame is configured to include an extension portion (not shown in the drawing) that protrudes downward on one lower side and the other lower side so that the first panel flange (410) and the second panel flange (420) can be positioned below the second mounting flange (920) or the first mounting flange (910).

[0147] That is, the extension portion protrudes to one side and the other side after the first panel flange (410) and the second panel flange (420) are spaced apart from each other in the downward direction, so that the first panel flange (410) and the second panel flange (420) are positioned below the second mounting flange (920) or the first mounting flange (910), thereby allowing the solar module (400) of the present invention to be installed on the upper side of the horizontal drainage channel (300).

[0148] At this time, the solar module (400) of the present invention is installed on the upper side of the other side of a module holder (900) located on the other side of a pair of adjacent module holders (900), and the other side is installed on the upper side of one side of a module holder (900) located on one side of a pair of adjacent module holders (900), thereby allowing rainwater on the surface to move to the module holder (900).

[0149] The fixing member (500), which is a main component of the present invention, fixes one side or the other side of the module holder (900) and the solar module (400), and a plurality of fixing members are installed on the upper part of the module holder (900) so that the solar module (400) can be stably and firmly fixed.

[0150] Specifically, the fixing member (500) of the present invention is configured to include a pair of hooks (510) that are coupled so that the first fixing flange (910) or the second fixing flange (920) is positioned on the upper inner side, and the upper surface (512) is in close contact with and presses the second panel flange (420) or the first panel flange (410), a fixing plate (520) positioned at the lower part of the module holder (900) and through which the lower part of the pair of hooks (510) passes, and a fixing bolt (530) that is screwed into the lower part of the hook (510).

[0151] That is, when the fixing member (500) of the present invention is installed so that the first panel flange (410) or the second panel flange (420) of the solar module (400) is positioned at the lower part of the second fixing flange (920) or the first fixing flange (910) of the module holder (900), a pair of hooks (510) are installed on the upper inner side of the hooks (510) so that the second fixing flange (920) or the first fixing flange (910) is positioned, and after the fixing plate (520) is positioned at the lower part of the module holder (900) so that the lower part of the pair of hooks (510) passes through, the hook (510) is pressed downward through the fixing bolt (530), so that the upper surface (512) of the hook (510) is fixed to the upper surface of the solar module (400). The second panel flange (420) or the first panel flange (410) is pressed so that the solar module (400) can be stably and firmly fixed to the module holder (900).

[0152] In addition, the fixing member (500) of the present invention is configured to include a packing (540) and a buffer spring (550), as described above in Example 1.

[0153] The above packing (540) prevents damage to the first mounting flange (910) or the second mounting flange (920) when the upper surface of the hook (510) presses the first panel flange (410) or the second panel flange (420) of the solar module (400), and has the effect of maintaining a more stable installation state.

[0154] The above-mentioned buffer spring (550) not only prevents damage to the hook (510) when the hook (510) is pressed downward through the fixing bolt (530), but also enables the first panel flange (410) or the second panel flange (420) of the solar module (400) to be pressed more stably by the hook (510), thereby realizing the effect of allowing the solar module (400) to be firmly fixed to the module holder (900).

[0155] In addition, the above-mentioned buffer spring (550) causes a buffering effect on the hook (510), thereby minimizing damage to the solar module (400) due to impacts such as strong winds or earthquakes.

[0156] At this time, the buffer spring (550) is characterized by having greater elasticity than the packing (540), thereby stably and firmly pressurizing the first panel flange (410) or the second panel flange (420) of the solar module (400) by the hook (510), and at the same time, the pressing force of the hook (510) can be easily adjusted, thereby obtaining the effect of stably and firmly fixing the solar module (400) to the module holder (900) more easily.

[0157] Additionally, since there is no need to minimize the space between the solar modules (400) in Example 2, the first blocking member (600) and the second blocking member (700) of Example 1 are not installed.

[0158] In connection with the above, the present invention comprises a control unit (9000), a gateway (1000), and a management server (2000) applicable to both Embodiments 1 and 2, and will be described in detail below with reference to Drawings 15 to 19. In addition, the equipment described below refers to some or all of the equipment of a solar power plant for solar power generation and the equipment of a smart farm, i.e., equipment that controls the environment for the growth of crops.

[0159] The above gateway (1000) is connected to facilities of an agricultural solar power smart farm, i.e., solar power generation facilities and smart farm facilities (facilities for crop growth), acquires information from the agricultural solar power smart farm facilities, and executes control commands transmitted from the outside.

[0160] The above management server (2000) is connected to the gateway (1000), receives information acquired from the gateway (1000), and based on this, provides information necessary for monitoring agricultural solar power smart farm facilities to a management terminal (10) connected via the Internet, thereby enabling monitoring of the current status of the facilities, and, if necessary, transmits a control command to the gateway (1000) to enable remote control.

[0161] At this time, the management server (2000) may include a database server (2100) and a web server (2200).

[0162] The above database server (2100) stores and manages information acquired from the gateway (1000).

[0163] The above web server (2200) provides web service when the above administrator terminal (10) accesses it via the Internet.

[0164] Various facilities of the solar power plant, i.e., various facilities of the agricultural solar smart farm, are connected to the gateway (1000) and linked to the management server (2000) via the Internet.

[0165] The above gateway (1000) is a communication relay device that acquires data from various facilities of an agricultural solar power smart farm, transmits the acquired data to the management server (2000) via the Internet, and executes control commands received from the management server (2000), such as circuit breaker control, inverter control, ESS control, and IDE control.

[0166] When the above gateway (1000) is connected to the above database server (2100), it transmits measurement and status values ​​acquired from agricultural solar power smart farm facilities to the above database server (2100), and the information transmitted in this way is stored in the above database server (2100).

[0167] Thereafter, the gateway (1000) can search for a control command corresponding to the gateway (1000) in the database server (2100), execute the corresponding control command, transmit the result of the control command execution to the database server (2100) for storage, and then terminate the connection.

[0168] The above process from connection to connection termination can be repeated at a certain cycle.

[0169] In the agricultural solar power smart farm complex system of the present invention, the information required for monitoring the above facilities may be characterized as information required to confirm at least one of power generation status, facility status, power generation history, and abnormal status.

[0170] That is, a solar power generation business operator / manager (user) can use the above management terminal (10) to connect to the web server (2200) of the above management server (2000) to check the power generation status, equipment status, power generation history, and abnormal status of the solar power plant, and control each facility of the power plant.

[0173] The management server (2000) of the agricultural solar power smart farm complex system of the present invention may include a device management server (2300) that supports the protocol of solar power plant facilities, i.e., agricultural solar power smart farm facilities, and provides firmware and setting files that enable remote control to a gateway (1000) that require such firmware and setting files.

[0174] Solar power plant facilities, i.e. agricultural solar smart farm facilities, are composed of equipment of various types and manufacturers, so communication protocols are usually different.

[0175] In order to support various protocols of agricultural solar power smart farm facilities in the gateway (1000) and to facilitate remote application of new protocols, the device management server (2300) may be provided, and remote updates of programs or protocols to be used in the gateway (1000) may be enabled from the device management server (2300).

[0176] Furthermore, most small and medium-sized solar power plants often use DHCP and virtual IP networks. In a virtual IP environment, remote access to the solar power plant is difficult because telecommunications companies generally do not allow this.

[0177] To solve this problem, it is possible to have the gateway (1000) of the solar power plant unit connect to the management server (2000) and enable control through the connected connection.

[0178] Therefore, it is desirable for the gateway (1000) to periodically connect to the management server (2000) to update its own programs and protocols.

[0179] For example, the gateway (1000) attempts to connect to the preset management server (2000), the management server (2000) uploads new firmware and a configuration file to the gateway (1000) using the connected connection, updates the uploaded configuration file of the gateway (1000) using the connected connection from the management server (2000), updates the uploaded firmware of the gateway (1000) using the connected connection from the management server (2000), and the gateway (1000) disconnects the connection when the management server (2000) disconnects or does not receive a command for a certain period of time. This series of processes can be repeated at a certain cycle.

[0185] The management server (2000) of the agricultural solar power smart farm complex system of the present invention may include an artificial intelligence server (2400) that uses artificial intelligence techniques to predict the amount of solar power generated by a solar power plant and a smart farm facility and the growth of smart farm crops.

[0186] Machine learning, a branch of artificial intelligence, is an analytical technique in which computers create algorithms for classification and prediction based on a training dataset, and then estimate the resulting values ​​for new data sets. Machine learning broadly encompasses supervised learning, unsupervised learning, and semi-supervised learning. Supervised learning refers to algorithms that provide classification or prediction values ​​for new data.

[0187] The artificial intelligence server (2400) of the agricultural solar power smart farm complex system of the present invention may be characterized by predicting solar power generation and smart farm growth (crop growth) by utilizing a random forest technique.

[0188] Among the machine learning algorithms widely used for classification, the decision tree technique is an excellent model, but it tends to overfit the training data.

[0189] Although such side effects can be minimized through methods such as pruning, they have their shortcomings.

[0190] To overcome the overfitting limitations of the Decision Tree technique, it is desirable to utilize the Random Forest technique.

[0191] The decision tree technique applied to the random forest technique is an algorithm that performs classification and prediction by finding the result value of the target variable based on specific variables.

[0192] The random forest technique is an algorithm that produces composite results by combining multiple decision trees, and it is an algorithm that returns the mode or average of the results produced from each tree.

[0193] The Random Forest technique is a type of ensemble learning method that operates by outputting classes (classification) or average predictions (regression analysis) from multiple decision trees constructed during the training process.

[0194] The biggest feature of the Random Forest technique is that the trees have slightly different characteristics due to randomness.

[0195] This property allows the predictions of each tree to be decorated, which in turn improves generalization performance.

[0196] Randomization also makes forests robust to noisy data. Randomization occurs during the training of each tree, and bagging, an ensemble learning method that utilizes random training data extraction, and randomized node optimization are frequently used.

[0197] These two methods can be used simultaneously to further enhance the randomization properties.

[0198] The training data set was used to build the model, 100 classifiers (ntree) were used, and the number of variables (mtry) selected for each node was 5. Looking at the results of the model, as shown in Figure 16, the mean square error (MSE) is approximately 9.0410, so it can be said to be a stable model, and the explanatory power of the model is 98.38%.

[0199] Looking at the variable importance of the constructed model, as shown in Figure 17, it refers to the state of minimizing the MSE value based on the average decrease value of the correct classification rate, and it can be seen that the important variables are td (dew point temperature), ta (air temperature), and current_kW (current output) in that order when constructing a model for predicting the optimal solar power generation amount.

[0200] The artificial intelligence server (2400) of the agricultural solar smart farm complex system of the present invention is as follows:

[0201]

[0202] (Here, MSE is the mean square error, is the actual power generation, It can be characterized by maintaining the current learning model or updating it with a new learning model based on the difference in the mean square error value calculated by (is the power generation predicted through the constructed prediction model).

[0203] The method of interpreting the power generation prediction accuracy of the constructed model is that the smaller the value of 'MSE', the smaller the difference between the actual power generation and the predicted power generation, so the closer the value is to 0, the better it is, and this serves as a standard for judging the accuracy of the prediction model.

[0204] As illustrated in Figure 18, interpreting the results from Figure 16, the mean square error (MSE) of 9.0410 suggests a difference of approximately 3 between the actual and predicted power generation, derived from combining time-of-day inverter and weather data and modeling. Examining some of the data confirms that the actual and predicted power generation are comparable within a small margin of error.

[0205] This system utilizes these models and a specific cycle of work schedules to link the database and R program, and loads the resulting data set into the Result Table. Furthermore, it updates the model with better performance through retraining.

[0206] Even in the case of Drawing 18, the average difference between the actual and predicted power generation is about 3, but there is a need to build a more accurate model for real-time monitoring and solar power predictive maintenance system.

[0207] Therefore, it is desirable to continuously update the model (Boogang_model) by utilizing more accumulated data and the R program in the database server (210) based on the repetition cycle (e.g., Monthly) to further reduce the mean square error of the model.

[0208] The artificial intelligence server (240) of the agricultural solar power smart farm complex system of the present invention may be characterized by changing the update cycle of relearning based on the difference in the mean square error value.

[0209] Rather than simply using a model with a lower MSE value during the model update process, it is desirable to change the update cycle of retraining by considering discrimination and efficiency.

[0210] For example, you can set the refresh cycle for relearning to one month and add a derived variable (grade) that can be used as a criterion for changing the refresh cycle for relearning.

[0211] In this case, if the derivative variable (grade) is less than 0, the relearning model is selected, and the set monthly cycle is judged to be appropriate and maintained as is.

[0212] However, if the existing model performs better with the addition of one month of data, the refresh cycle can be changed to earlier than one month.

[0213] If the difference is relatively small, between 0 and 1, retraining can be performed using data from 1 week later (1 month + 1 week). If it is between 1 and 2, retraining can be performed after 2 weeks, and if it is 2 or more, retraining can be performed after 3 weeks.

[0214] By utilizing the derived variable (grade), you can effectively manage data utilization and model retraining.

[0215] The artificial intelligence server (2400) of the agricultural solar power smart farm complex system of the present invention may be characterized by tagging an error state based on the square of the difference between the actual power generation amount and the predicted power generation amount, and storing the data set of the corresponding result in the database server (2100).

[0216] The constructed model can be used to create and apply an 'err' variable for predictive maintenance monitoring of solar power generation.

[0217] The 'err' variable can be used to check the error between the actual solar power generation figures and the predicted power generation figures of the solar power generation prediction model built using artificial intelligence technology, and was created for use in predictive maintenance monitoring of solar power generation figures.

[0218] The 'err' variable is the following expression

[0219]

[0220] (Here, is the actual power generation, It can be calculated by the predicted power generation amount through the constructed prediction model.

[0221] The closer the calculated 'err' value is to 0, the better the constructed model predicted the power generation at that time. If the 'err' value suddenly increases, it indicates that there is a difference between the predicted power generation and the actual power generation.

[0222] Based on this, solar power generation monitoring can be performed.

[0223] When the 'err' value is large, solar power generation predictive maintenance monitoring is possible by identifying the corresponding region or time and checking the factors that affected the actual power generation.

[0224] This not only provides forecasted power generation for a given area and time, but also provides baseline information for monitoring, enabling more specialized predictive maintenance.

[0225] When running using a statistical analysis program (such as R), weather data and inverter data are obtained from the database server (2100), a random forest algorithm for predicting solar power generation is built, the mse of the existing model and the relearning model are compared, and if the mse of the existing model is lower, the existing model is selected, and if the mse of the relearning model is lower, a model with better performance is continuously built by updating with the relearning model, and if err, which is the square of the difference between the actual power generation and the predicted power generation, is larger than a specific condition (e.g., 80th percentile), an error state can be tagged as y = 1, which indicates that a problem may occur, and if it is smaller, y = 0, which indicates that there is no abnormality.

[0226] The data set of the results is accumulated in the database server (210), and when a large amount of data is accumulated, new values ​​such as an inverter automation control and management system can be created by utilizing error status variables.

[0227] As illustrated in Drawing 19, the control unit (9000) of the solar power plant monitoring and control system according to one embodiment of the present invention includes a protection relay (9100) and a switch (9200).

[0228] The above protective relay (9100) blocks or connects the electric path between the grid and the solar power plant equipment.

[0229] Drawing 19 illustrates a portion of a sequence control circuit using a protective relay (9100) and a switch (9200). Sequence control is defined as a control that sequentially performs each control step according to a predetermined order, and the sequence control circuit is configured using switches, relays, timers, magnetics, etc.

[0230] In Drawing 19, when the ON switch of the protection relay (9100) is connected (closed), the electric path between the grid and the solar power plant equipment can be connected, and when the OFF switch of the protection relay (9100) is connected (closed), the electric path between the grid and the solar power plant equipment is cut off.

[0231] The above protective relay (9100) blocks (locks) the power path between the grid and the solar power plant equipment when an abnormality occurs that has a negative impact on the grid or solar power plant equipment.

[0232] The above protective relay (9100) can connect the power line between the grid and the solar power plant equipment (release the lock) only after a problem that adversely affects the grid or the solar power plant equipment is resolved.

[0233] A protective relay detects abnormal conditions, such as short circuits or ground faults, in a power system, or when abnormal operation that adversely affects the rest of the system occurs, and issues a command to quickly disconnect the affected portion from the system. A single relay or a combination of multiple relays can be employed to perform this function. Protective relays require selectivity to block fault sections with a minimum tripping distance, sensitivity to ensure that protection performance is not affected by the magnitude of the fault current, and speed and reliability to prevent the expansion of faults.

[0234] That is, a relay that blocks an electric circuit when it is overloaded or malfunctions is installed, and this is called a protective relay.

[0235] The above switch (9200) connects or breaks the electric path between the grid and the solar power plant equipment.

[0236] In Drawing 19, when the ON switch of the protection relay (9100) is connected and the DO1 switch of the switch (9200) is connected (closed), the electric path between the system and the solar power plant equipment is connected, and when the DO2 switch of the protection relay (9100) is connected (closed), the electric path between the system and the solar power plant equipment is cut off.

[0237] The above switch (9200) is installed between the grid and the solar power plant equipment, and can connect (On) or cut off (Off) the electric path between the grid and the solar power plant equipment.

[0238] The above switch (9200) refers to a device that opens (connects) and closes (breaks) a line, such as a circuit breaker, a disconnector, or a switch. A load break switch (LBS), a vacuum circuit breaker (VCB), an air circuit breaker (ACB), a molded case circuit breaker (MCCB), etc. can be used as the above switch (920).

[0239] Load Breaker Switches (LBS) are widely used as inlet switches in substations and are employed to prevent phase loss in the event of a power fuse blowing. When a three-phase load is present, it is recommended to use a power fuse combined with a three-pole load breaker with a trip device. The operation is designed so that the operation indicator, which houses the power fuse, protrudes, the trip device operates, and the force accumulated in the spring automatically opens the movable load contact. Therefore, any power fuse connected to the three phases is prevented from being phased.

[0240] Vacuum circuit breakers (VCBs) utilize the high dielectric strength of vacuum to rapidly extinguish arc products through the rapid diffusion of the vacuum. These circuit breakers feature short tripping times and unaffected by frequency. Widely used in 22.9kV applications, they are quiet and oil-free, minimizing the risk of fire. Furthermore, they are compact, lightweight, and require minimal operating power, requiring only a simple operating mechanism. Their simple construction facilitates easy maintenance.

[0241] An air circuit breaker (ACB) is a circuit breaker in which the opening and closing operation between contacts in an electric circuit is ideally performed in the air. When applied appropriately considering the current ratio, it automatically opens the circuit by predicting overcurrent in advance to avoid current loss, or opens and closes the circuit manually. It is mainly used in circuits of 1,000 V AC or less.

[0242] A molded case circuit breaker (MCCB) is a device that assembles the switching mechanism, trip device, etc. into an insulating container. It can open and close a current-carrying circuit manually or electrically, and automatically cuts off the current in the event of an abnormal condition such as an overload or short circuit.

[0243] When explaining the operation of the above protective relay (9100) and switch (9200), when the protective relay (9100) is in a blocking state, the switch (9200) also enters a blocking state, and when the switch (9200) is in a blocking state, the protective relay (9100) also enters a blocking state.

[0244] That is, when either the protective relay (9100) or the switch (9200) is in a cut-off state, the other one also becomes cut-off.

[0245] When the above protective relay (9100) is connected, the switch (9200) can be switched to the connected state, and when the protective relay (9100) and the switch (9200) are connected, the power line between the grid and the solar power plant, i.e., the agricultural solar power smart farm facility, is connected.

[0246] When the above protection relay (9100) is in a cut-off state, the switch (9200) is also in a cut-off state when trying to switch to a connected state.

[0247] That is, in order to connect the protective relay (9100) and the switch (9200), the protective relay (9100) must be connected.

[0248] The control unit (9000) of the solar power plant monitoring and control system according to one embodiment of the present invention may be characterized in that it is capable of switching the connection state of the protection relay (9100) and the switch (9200) according to a control command transmitted from the gateway (1000).

[0249] As illustrated in Drawing 19, the control unit (9000) of the solar power plant monitoring and control system according to one embodiment of the present invention may include a first relay (9310), a second relay (9320), and a third relay (9330).

[0250] The first relay (9310) connects the contact when the switch (9200) is in a connected state, and when the contact of the first relay (9310) is connected, it transmits a signal to the gateway (1000) that can confirm that the switch (9200) is in a connected state.

[0251] The second relay (9320) connects the contact when the switch (9200) is in a blocked state, and when the contact of the second relay (9320) is connected, a signal that can confirm that the switch (9200) is in a blocked state is transmitted to the gateway (1000).

[0252] The third relay (9330) may be characterized in that it connects a contact when the switch (9200) is in a blocked state, and when a control command corresponding to a recovery command is transmitted from the gateway (1000) while the contact of the first relay (9310) is connected, it switches the state of the protection relay (9100) to a connected state.

[0253] In Drawing 19, when the DO1 switch of the switch (9200) is connected (sticky), the contacts of the first relay (9310) are connected (sticky), and when the DO2 switch of the protection relay (9100) is connected (sticky), the contacts of the second relay (9320) and the third relay (9330) are connected (sticky).

[0254] When the contact of the third relay (9330) is connected (sticky), a control command corresponding to a recovery command can be transmitted from the gateway (1000) through a line connected to the contact of the third relay (9330), and when the control command corresponding to the recovery command is transmitted from the gateway (1000), the ON switch of the protection relay (9100) is connected (sticky) by the control command, thereby enabling the electric path between the grid and the solar power plant equipment to be connected. Thereafter, when the DO1 switch is connected (sticky) by 485 communication or the like, the electric path between the grid and the solar power plant equipment is connected. In other words, the solar power equipment can be remotely reset and operated after a problem that has a negative impact on the grid or the solar power plant equipment has been resolved.

[0255] An example of a remote control method for solar power plant facilities is explained below, using Drawing 19 as an example.

[0256] 1) Remote driving method

[0257] When the ON switch of the protection relay (9100) is connected, if a DO 485 communication DO1 signal is sent from the communication control, the DO1 switch of the switch (9200) is connected (closed) and remotely closed, and if a DO 2 signal is sent, the DO2 switch is connected (closed) and remotely tripped.

[0258] Manual operation can be turned ON / OFF with the manual lever attached to the circuit breaker.

[0259] 2) Recovery method when protective relay operates

[0260] When signal DO3 is sent, the switch (9200) moves to the OFF position (when the DO2 switch is connected) and the protection relay (9100) is restored (when the ON switch is connected) (recovery can be confirmed by the first relay (9310))

[0261] Then, by sending a remote signal to DO1, the power line between the grid and the solar power plant equipment can be connected.

[0262] Although an example of a circuit consisting of three relays was given above, the present invention is not limited thereto, and it is possible to implement the invention by varying the number of relays as needed, such as by giving a signal to check the status of a protective relay (9100) or a switch (9200) or receiving a recovery signal.

[0263] The above has been described with reference to a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment, and a person having ordinary skill in the art to which the present invention pertains can make various changes without departing from the gist of the present invention through the above embodiment.
