Description

Technical Field

[0001] The present invention relates to the technical field of power supply and distribution, and particularly to a photovoltaic-storage-direct-current-flexible intelligent control system. Background Art

[0002] Photovoltaic-storage-direct-current-flexible is the abbreviation of the application of four technologies, namely solar photovoltaic power generation, energy storage, direct current power distribution, and flexible interaction, in the building field. In recent years, the technologies related to photovoltaic-storage-direct-current-flexible have been continuously developing and making progress in aspects such as photovoltaic power generation, energy storage, and power allocation. With the development of photovoltaic-storage-direct-current-flexible, zero-carbon buildings, that is, buildings with zero carbon emissions, are expected to be realized and widely promoted on a large scale.

[0003] In this technology, an important development direction is the decentralized layout of photovoltaic power generation and energy storage. That is to say, while continuously building solar power stations, actively building user-side photovoltaic power generation and energy storage devices. This method has advantages such as reducing transmission losses and realizing emergency power supply. However, in actual applications, there are some problems: when building facilities on the power station side and the user side, the flexibility and generality of mutual allocation between different devices are poor. For energy storage devices, with the development of technology, it is relatively easy to allocate charging modules or battery packs between energy storage devices of different scales. But for photovoltaic devices, on the power station side, usually larger-scale photovoltaic devices are used, and the orientations of photovoltaic panels in different blocks of a power station are different, and the requirement for whether each photovoltaic panel can follow the sun's rotation is relatively low. In addition, the photovoltaic devices used in power stations usually belong to equipment for long-term planned construction. For the user side, usually smaller photovoltaic devices are used, and generally, solar position tracking is required to improve the light energy utilization efficiency. Therefore, generally speaking, the photovoltaic devices and their components used on the power station side and the user side are not universal. Another main problem is that the stability of the construction of user-side photovoltaic devices is not high, including but not limited to the following situations: changes in the relevant contract time and content signed between users and power supply departments; increases or decreases in the photovoltaic power generation capacity required by users; changes in local users, etc. In these situations, more flexible and general photovoltaic-related devices are required on the user side. In a better case, these devices should be able to be universal with some components of the devices used on the power station side. Summary of the Invention

[0004] In view of the above defects, the present invention provides a photovoltaic-storage-direct-current-flexible intelligent control system, which can realize flexible power generation, power supply, and power distribution scheduling, and the universal photovoltaic units used on the power station side and the user side can be easily loaded and unloaded in a modular manner, with strong generality and flexibility.

[0005] In order to achieve the object of the present invention, the following technologies are proposed: A photovoltaic-storage-direct-flexible intelligent control system includes an intelligent operation and maintenance control center and a photovoltaic subsystem, a energy storage subsystem, a DC power consumption subsystem, and a flexible power consumption subsystem connected thereto. The photovoltaic subsystem includes a power station-side photovoltaic module, a user-side control component, and a user-side photovoltaic module.

The numbers of the DC power consumption subsystem, the flexible power consumption subsystem, the user-side control component, the user-side photovoltaic module, and the user-side energy storage component are all multiple. The user-side photovoltaic module is respectively connected to the user-side control component and the user-side energy storage component. The power station-side photovoltaic module is connected to the power station-side energy storage component. The DC power consumption subsystem is respectively connected to the power station-side energy storage component, the user-side energy storage component, and the power grid. The flexible power consumption subsystem is also respectively connected to the power station-side energy storage component, the user-side energy storage component, and the power grid; Both the power station-side photovoltaic module and the user-side photovoltaic module adopt photovoltaic units, and the photovoltaic unit includes: A photovoltaic panel, on the back of which there is a junction box, and guiding rectangular tubes are respectively arranged on the four end faces of the junction box. A plurality of seat mounting blocks with lower ends open are arranged at the lower part of the back of the photovoltaic panel; Four module assembly components are respectively embedded in the four guiding rectangular tubes. The module assembly component includes a pull ring. One end of the pull ring is provided with two connecting rods that are both inserted through one side surface of the guiding rectangular tube. One end of the connecting rod is provided with a slider. When one end of the photovoltaic panel is assembled with other photovoltaic panels, the slider of one module assembly component extends into the guiding rectangular tube where another module assembly component is located.

[0006] The beneficial effects of this technical solution are as follows: 1. The power station-side photovoltaic module and the user-side photovoltaic module adopt a common photovoltaic unit, and can be quickly and modularly loaded and unloaded through the module assembly component, and can be conveniently exchanged when upgrading or adjusting between the power station side and the user side, or on the user side, with good versatility and flexibility.

[0007] 2. Through this system, relatively flexible photovoltaic power generation, electricity storage, and power consumption methods can be realized, which can reduce the power supply pressure on the power grid and power stations, and is conducive to achieving zero carbon in buildings.

[0021] like Figures 1 to 11 The shown system is a photovoltaic, energy storage, direct current and flexible intelligent control system, including an intelligent operation and maintenance control center, a photovoltaic subsystem, an energy storage subsystem, a direct current electronic system, and a flexible electronic system.

[0022] See Figure 1, the intelligent operation and maintenance control center is respectively connected to the photovoltaic subsystem, the energy storage subsystem, the DC power consumption subsystem, and the flexible power consumption subsystem. The photovoltaic subsystem includes a power station-side photovoltaic module, a user-side control component, and a user-side photovoltaic module. The energy storage subsystem includes a power station-side energy storage component and a user-side energy storage component. The number of the DC power consumption subsystem, the flexible power consumption subsystem, the user-side control component, the user-side photovoltaic module, and the user-side energy storage component is multiple. In the drawings, for the convenience of representation, only one of the above subsystems or components is shown. Similarly, when the number is multiple, in actual use, each user has a set of DC power consumption subsystem, flexible power consumption subsystem, user-side control component, user-side photovoltaic module, and user-side energy storage component. The user-side photovoltaic module is respectively connected to the user-side control component and the user-side energy storage component. The power station-side photovoltaic module is connected to the power station-side energy storage component. The DC power consumption subsystem is respectively connected to the power station-side energy storage component, the user-side energy storage component, and the power grid. The flexible power consumption subsystem is also respectively connected to the power station-side energy storage component, the user-side energy storage component, and the power grid. And an AC / DC module is respectively arranged between the DC power consumption subsystem and the power grid, between the user-side energy storage component and the flexible power consumption subsystem, and between the power station-side energy storage component and the flexible power consumption subsystem. In this embodiment, the AC / DC module adopts an off-grid inverter, and the physical structures of the power station-side energy storage component and the user-side energy storage component adopt energy storage cabinets.

[0023] More specifically, the user-side control component adopts a solar tracking system, which is a commonly used device at present, and its working mode will not be elaborated. The solar tracking system includes a photosensitive sensor array and a controller that receives sensor signals. The controller adopts a PLC.

[0024] Both the power station-side photovoltaic module and the user-side photovoltaic module adopt the photovoltaic unit as Figures 2 to 7 shown. The photovoltaic unit includes a photovoltaic panel 1 and a module assembly component 2.

[0025] From the side facing the sun to the back, the photovoltaic panel 1 includes, in sequence, an outer frame layer, a photovoltaic glass, a first adhesive film layer, a battery pack layer, a second adhesive film layer, and a backplane layer. A junction box 11 is provided on the back of the photovoltaic panel 1. Specifically, the junction box 11 is fixed to one side of the backplane layer. For the sake of convenience of representation, and since the junction box 11 is a technology of well-known common sense, its components such as ports and connecting wires are not specifically shown in the drawings. Four guiding rectangular tubes 12 are respectively provided outside the four end faces of the junction box 11. A side groove group is formed on one side of the guiding rectangular tube 12. The side groove group includes four parallel telescopic grooves 14, and a translation groove 13 that is vertically provided at one end of the telescopic groove 14 and communicates with the telescopic groove 14. According to the order of the positions where the translation groove 13 communicates, the first, second, third, and fourth telescopic grooves are defined for subsequent description. A pair of symmetrically arranged screw hole groups are respectively provided on both sides of each telescopic groove 14. The screw hole groups are opened on the back of the photovoltaic panel 1. Specifically, they are opened on one side of the backplane layer. The screw hole groups include a first retracted position screw hole 15, a second retracted position screw hole 16, a first deployed position screw hole 17, and a second deployed position screw hole 18. The distances from the first retracted position screw hole 15 and the first deployed position screw hole 17 to the guiding rectangular tube 12 are less than the distances from the second retracted position screw hole 16 and the second deployed position screw hole 18 to the guiding rectangular tube 12. The spacing between the first retracted position screw hole 15 and the first deployed position screw hole 17 is the same as the spacing between the second retracted position screw hole 16 and the second deployed position screw hole 18. A number of mounting blocks 19 are provided at the lower part of the back of the photovoltaic panel 1. The lower ends of the mounting blocks 19 are open. In this embodiment, there are two mounting blocks 19 on the back of a single photovoltaic panel 1. Specifically, the mounting blocks 19 are also located on one side of the backplane layer.

[0026] The number of module assembly components 2 of each photovoltaic unit is four, which are respectively embedded in four guiding rectangular tubes 12 and are used for assembling one photovoltaic panel 1 with another photovoltaic panel 1 at one end of the upper, lower, left, and right ends of a photovoltaic panel 1. The module assembly component 2 includes a pull ring 21. Z-shaped parts 22 are respectively arranged on both side surfaces of the pull ring 21. One end of the side of the two parallel sides of the Z-shaped part 22 that is attached to the back surface of the photovoltaic panel 1 is provided with a first through hole 23 that matches the screw holes in the screw hole group. The first through hole 23 and the screw holes in the screw hole group are connected and fixed by first screws 24. In this embodiment, the first screws 24 are hexagon socket head cap screws, which are convenient for the staff to load and unload. One end of the pull ring 21 is provided with two connecting rods 25, and the connecting rods 25 are slidably matched in the side groove group. The connecting rods 25 include two working states. In the first working state, the two connecting rods 25 are both slidably matched in the translation groove 13. In the second working state, the two connecting rods 25 are respectively slidably matched in two spaced telescopic grooves 14, and there is only one telescopic groove 14 at the interval. More specifically, the two connecting rods 25 are respectively slidably matched in the first and third telescopic grooves 14, or are respectively slidably matched in the second and fourth telescopic grooves 14. One end of the connecting rod 25 is provided with a slider 26. The width of the gap between the two sliders 26 is the same as the width of a single slider 26. When a connecting rod 25 is slidably matched in the first telescopic groove 14, one side surface of the slider 26 connected to the connecting rod 25 abuts against an inner side surface of the guiding rectangular tube 12. When a connecting rod 25 is slidably matched in the fourth telescopic groove 14, one side surface of the slider 26 connected to the connecting rod 25 abuts against the other inner side surface of the guiding rectangular tube 12. When the end of the photovoltaic panel 1 is not assembled with other photovoltaic panels 1, the two first through holes 23 of the module assembly component 2 at the end are respectively fixed to the first retracted position screw hole 15 of a screw hole group and the second retracted position screw hole 16 of another screw hole group by first screws 24.

[0027] As Figure 4 , Figure 5 shown, when one end of the photovoltaic panel 1 is assembled with other photovoltaic panels 1, each connecting rod 25 of the module assembly components 2 at the assembly ends of the two photovoltaic panels 1 respectively moves to one end in the two telescopic grooves 14. The slider 26 of one module assembly component 2 extends into the guiding rectangular tube 12 where the other module assembly component 2 is located. The two first through holes 23 of the module assembly component 2 at the assembly end are respectively fixed to the first deployed position screw hole 17 of a screw hole group and the second deployed position screw hole 18 of another screw hole group by first screws 24. And at this time, as Figure 5 shown, the four sliders 26 of the two module assembly components 2 at the assembly end are arranged in a staggered manner, and the side surfaces of adjacent sliders 26 abut against each other.

[0028] As Figure 8 , Figure 9 shown, the photovoltaic modules on the power station side include a plurality of photovoltaic units assembled through module assembly components 2 and arranged in a rectangular array, and further include a bottom stabilizing unit 3 and a top stabilizing unit 4.

[0029] The bottom stabilizing unit 3 is arranged on the ground of the photovoltaic power station when in use, and includes a plurality of bases 31, a bottom plate 32 is arranged on the base 31, and a plurality of groups of first plug blocks 33 are arranged on the bottom plate 32. Each group of first plug blocks 33 is respectively used to be inserted into the mounting block 19 of the photovoltaic unit located in the bottom row of the photovoltaic assembly on the power station side. In this embodiment, the photovoltaic assembly on the power station side includes Figure 8 The ten rows of photovoltaic units shown in the figure have a total of ten groups of first plug blocks 33. The upper portion of the first plug blocks 33 is inclined, so that the photovoltaic units are also inclined when installed.

[0030] The top stabilizing unit 4 is arranged on one side of the bottom stabilizing unit 3, and includes a pair of support rods 41. A steel cable 42 is provided between the upper ends of the two support rods 41, which is used to support the back of a row of photovoltaic units located at the top end to prevent the photovoltaic units installed in the photovoltaic modules on the power station side from tipping backwards under the action of gravity.

[0031] like Figure 10 , Figure 11 As shown, the user-side photovoltaic assembly includes a plurality of photovoltaic units, a driving unit 5 and a switching unit 6.

[0032] The driving unit 5 is set on the roof of the user's house when in use and is controlled by a controller. It includes a base 51, on which an electric turntable 52 is provided. A bracket 53 is provided at the upper end of the electric turntable 52, and a rotating motor 54 is provided at the upper end of the bracket 53. A roller 55 is provided at the output end of the bracket. An annular groove 56 is provided inwardly on the circumference of the roller 55. Both ends of the circumference of the annular groove 56 are respectively provided with protrusions 57, and mounting holes 58 are provided on the protrusions 57. A rotating seat 59 is also provided on the electric turntable 52, and one end of the roller 55 is rotatably matched with the rotating seat 59.

[0033] The adapter unit 6 is arranged on the annular groove 56, including an arc plate 61 assembled on one end of the circumferential side of the annular groove 56, and the two ends of the arc plate 61 are respectively provided with a cover block 62 that abuts against one side of the protrusion 57 during assembly, and the cover block 62 is provided with a second through hole 63 matching the mounting hole 58, and the second through hole 63 is connected and fixed to the mounting hole 58 by a second screw 64. In this embodiment, the second screw 64 adopts a cross screw. A connecting plate is also provided on the outer peripheral side of the arc plate 61, and a cross block 65 is provided at one end of the connecting plate. A plurality of groups of second plug-in blocks 66 are provided on the upper end surface of the cross block 65, and each group of second plug-in blocks 66 is respectively used to be inserted into the seat block 19 of the photovoltaic unit located in the bottom row of the user-side photovoltaic assembly. In this embodiment, the user-side photovoltaic assembly includes the following Figure 10 The two rows of photovoltaic units shown thus have two groups of first plug-ins 33 .

[0034] Working method: First, the overall operation of the system is explained from the perspective of electricity consumption: whether it is a DC load connected to a DC electronic system or an AC load connected to a flexible electronic system, the surplus power of the energy storage components on the user side is used first. If there is no surplus power in the energy storage components on the user side, the surplus power of the energy storage components on the power station side is used. If there is no surplus power in the energy storage components on the power station side, electricity is used from the grid. Since each subsystem is connected and communicates with the smart operation and maintenance control center, the above controls are uniformly executed by the smart operation and maintenance control center.

[0035] Preferably, the DC power system or the flexible power system returns excess power of any energy storage component to the grid.

[0036] From the perspective of the construction of the power station, since the construction of a power station is usually a relatively long-term plan, the number and arrangement of photovoltaic units in each area will be determined. Furthermore, after the bottom stabilization unit 3 and the top stabilization unit 4 are constructed according to the plan, the photovoltaic units can be assembled.

[0037] From the user-side configuration point of view, the driving unit 5 is placed first, and then different adapter units 6 can be installed according to the specific number and method of use of the photovoltaic units, or when the demand increases or decreases, which is more flexible.

[0038] The above are only some of the embodiments listed in this application and are not intended to limit this application.
