Technical Field

[0001] The present invention relates to the field of photovoltaic power generation, and in particular to a snow removal device based on distributed energy storage, vibration and photovoltaic panel heating, a snow removal method based on distributed energy storage, vibration and photovoltaic panel heating, a snow removal system based on distributed energy storage, vibration and photovoltaic panel heating, and a snow removal method based on the system. Background Art

[0002] Photovoltaic power generation occupies a large proportion in the field of new energy power generation due to its regional light layout, high power generation efficiency, green and low-carbon characteristics. Due to its power generation energy source, photovoltaic power plants are usually built in high altitudes or Gobi, desert and other areas. These areas have sufficient sunshine, but also have the problem of large temperature difference between day and night. Photovoltaic panels are prone to ice or snow in winter. Whether it is snow or ice, it is easy to block sunlight, thereby affecting the power generation efficiency of photovoltaic panels and causing waste of energy and resources.

[0003] Currently, the solution for snow removal (including ice removal) of photovoltaic panels is to install a vibration device and a heating device on the photovoltaic panels, heat the snow on the photovoltaic panels by the heating device, and then shake the snow with the vibration device. For example, a snow removal device for solar panels is proposed in Chinese patent document No. CN116961564A.

[0006] 2. An independent heating device needs to be installed. The heating device has an additional physical structure, and its operation will interfere with the circuit of the photovoltaic panel and limit the wiring of the photovoltaic panel.

[0007] 3. The heating uniformity of the heating device is poor, the temperature of the photovoltaic panel is uneven, and the snow removal efficiency is not high enough; in addition, the heating device itself needs to heat up and maintain temperature before heating the photovoltaic panel, and the heating device itself will consume more electricity;

[0008] 4. The current snow removal device can only achieve regional centralized control, that is, it can work or stop at the same time, and it is impossible to perform independent snow removal control for each photovoltaic panel. Summary of the invention

DETAILED DESCRIPTION

[0048] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0049] Any feature disclosed in this specification (including any additional claims and abstract), unless otherwise stated, may be replaced by other equivalent or alternative features having similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0050] Example 1

[0051] A snow removal device based on distributed energy storage vibration and photovoltaic panel heating is used to remove snow from the photovoltaic panel 201 of the distributed power generation unit 300. The photovoltaic panel 201 is connected to the power optimizer 202 (MPPT). The power optimizer 202 usually performs maximum power point tracking on the current output by the photovoltaic panel 201 and outputs it to the inverter 302 for inversion processing. In this embodiment, the power optimizer 202 of each photovoltaic panel 201 is also connected to the distributed energy storage unit 203 to transmit the excess electric energy generated by the photovoltaic panel 201 to the distributed energy storage unit 203 for regular storage. The so-called distributed energy storage unit 203 is an energy storage element installed near the photovoltaic panel 201. Its capacity is limited. Usually, one or a small number of photovoltaic panels 201 are connected to one distributed energy storage unit 203. This embodiment takes one photovoltaic panel 201 and one distributed energy storage unit 203 as an example.

[0052] The snow removal device also includes a vibration module 205, which is used to be installed on the photovoltaic panel 201, and snow removal is achieved by vibrating the photovoltaic panel 201. Usually, the vibration module 205 is composed of a vibration motor or necessary peripheral facilities, and its structure belongs to the common design in traditional photovoltaic snow removal devices. No additional changes are made to it in this application, that is, the vibration module 205 can use the existing design. The vibration module 205 is connected to the distributed energy storage unit 203, and its electrical energy is used as a working power supply. The snow removal device on each photovoltaic panel 201 can be connected to the distributed energy storage unit 203 to which the photovoltaic panel 201 is connected to draw electricity, and in fact it can also be connected to other distributed energy storage units 203 to draw electricity. It is preferred to use the former, so that there is no need to worry about the uneven load problem of each distributed energy storage unit 203.

[0053] As another important component of the snow removal device, the snow removal device also includes a reverse power supply circuit 204, which is connected between the photovoltaic panel 201 and the distributed energy storage unit 203 when installed. The so-called reverse power supply is relative to the conventional current direction. Usually, the photovoltaic panel 201 generates electricity and transmits the electric energy to the distributed energy storage unit 203 for storage. Reverse power supply is the transmission of current from the distributed energy storage unit 203 to the photovoltaic panel 201. Whether a photovoltaic panel 201 is equipped with a distributed energy storage unit 203, or a string of photovoltaic panels 201 is equipped with a distributed energy storage unit 203, on average, the voltage of the distributed energy storage unit 203 is compatible with that of a single photovoltaic panel 201, so reverse power supply does not need to consider the problem of voltage transformation.

[0054] In some embodiments, the reverse power supply circuit 204 includes a buck-boost subcircuit and a charge-discharge electronic circuit. The buck-boost subcircuit is connected to the distributed energy storage unit 203, and the charge-discharge electronic circuit is connected between the buck-boost subcircuit and the photovoltaic panel 201. During reverse charging, the buck-boost subcircuit is first turned on, the charge-discharge electronic circuit is turned off, the voltage of the distributed energy storage unit 203 is increased, and then the buck-boost subcircuit is turned off, and the charge-discharge electronic circuit is turned on, so that the boosted current is smoothly transmitted from the distributed energy storage unit 203 to the photovoltaic panel 201. Due to the injection of current, the internal current of the photovoltaic panel 201 will increase, thereby generating heat and heating the photovoltaic panel 201, and because the current is equal everywhere, the heating is uniform. In addition, the voltage of the current injected into the distributed energy storage unit 203 will not exceed the rated voltage of the photovoltaic panel 201, so the photovoltaic panel 201 will not be damaged.

[0055] With the help of the reverse power supply circuit 204, the photovoltaic panel 201 can also charge the distributed energy storage unit 203. When it is necessary to charge the distributed energy storage unit 203 through the reverse power supply circuit 204, the charging and discharging electronic circuit is first turned on, and the buck-boost sub-circuit is turned off. With the help of the turned-off buck-boost sub-circuit, the photovoltaic panel 201 charges the distributed energy storage unit 203 by stepping down, and then the charging and discharging electronic circuit is turned off, and the buck-boost sub-circuit is turned on to continue to deliver the remaining electric energy during the step-down to the distributed energy storage unit 203 for storage.

[0056] For example, Figure 2 As shown, the charge and discharge electronic circuit includes a switch tube T1, and the buck-boost subcircuit includes a switch tube T2 and an inductor L connected in series. The inductor L is connected to the positive electrode of the distributed energy storage unit 203, and the switch tube T2 is connected to the negative electrode of the distributed energy storage unit 203; the switch tube T1 outputs the positive electrode from the photovoltaic panel 201 and is connected between the inductor L and the switch tube T2. The diode D1 plays a reverse isolation role, and the capacitors on both sides play a voltage stabilization isolation role.

[0057] During reverse charging, that is, when the distributed energy storage unit 203 supplies power to the photovoltaic panel 201, the boost process 1 is first executed, at which the switch tube T2 is turned on and the switch tube T1 is turned off to charge the inductor L. Then, the boost process 2 is executed, the switch tube T1 is turned on and the switch tube T2 is turned off, at which time the voltage of the inductor L and the voltage of the distributed energy storage unit 203 are discharged to the photovoltaic panel 201 together, realizing boost discharge.

[0058] During forward charging, the process is reversed. Figure 3 As shown, the step-down charging process 1 is first executed, the switch tube T1 is turned on, and the switch tube T2 is turned off. At this time, the photovoltaic panel 201 charges the distributed energy storage unit 203. Due to the effect of the inductor, the inductor L is charged first, thereby achieving step-down. Then, the step-down charging process 2 is executed, the switch tube T1 is turned off, and the switch tube T2 is turned on. The inductor L releases the stored electric energy to the distributed energy storage unit 203 for storage.

[0059] To realize distributed single-board control, the snow removal device also includes an Internet of Things communication module 200, which is respectively connected to the power optimizer 202, the distributed energy storage unit 203, the vibration module 205 and the reverse power supply circuit 204. The Internet of Things communication module 200 serves as an interactive bridge between the snow removal device and the control center 301, realizing the reporting of local data and the transmission of instructions issued by the control center 301 to the target module / unit.

[0060] For example, if the control center 301 needs to control the vibration of a certain single-board photovoltaic panel 201, a first instruction is sent to the Internet of Things communication module 200 of the snow removal device of the photovoltaic panel 201, and the Internet of Things communication module 200 transmits the first instruction to the connected vibration module 205. The vibration module 205 adjusts the working state in response to the first instruction received by the connected Internet of Things communication module 200. The working state adjusted by the vibration module 205 includes a switch state, or also includes a vibration level state.

[0061] Similarly, the control center 301 sends a second instruction to the IoT communication module 200 of the snow removal device of the target photovoltaic panel 201, and the IoT communication module 200 transmits the second instruction to the connected reverse power supply circuit 204. The reverse power supply circuit 204 controls the distributed energy storage unit 203 to discharge or stop discharging to the photovoltaic panel 201 in response to the second instruction received by the connected IoT communication module 200. Discharging is the reverse power supply mentioned above.

[0062] In addition, the control center 301 can also send a third instruction to the Internet of Things communication module 200 of the snow removal device of the target photovoltaic panel 201, and the Internet of Things communication module 200 transmits the third instruction to the connected reverse power supply circuit 204. The reverse power supply circuit 204 controls the photovoltaic panel 201 to charge or stop charging the distributed energy storage unit 203 in response to the third instruction received by the connected Internet of Things communication module 200. Charging is the forward charging mentioned above.

[0063] In addition, the IoT communication module 200 also reports the working parameters of the power optimizer 202 and the distributed energy storage unit 203, so that the control center 301 can understand the power generation status of each photovoltaic panel 201 on site, and thus analyze the snow accumulation status, that is, which photovoltaic panels 201 have snow accumulation and what the snow accumulation situation is, so as to control the snow removal devices of the corresponding photovoltaic panels 201 to remove snow, while keeping the snow removal devices of other photovoltaic panels 201 unchanged.

[0064] The working parameters reported by the IoT communication module 200 can be set to be reported regularly or when needed, depending on the environment, season and other determining factors where the photovoltaic panel 201 is installed. That is, the IoT communication module 200 reports the working parameters of the distributed energy storage unit 203 and / or the power optimizer 202 regularly, or reports them in response to the fourth instruction received from the control center 301.

[0065] Through the snow removal device of this embodiment, low-cost and high-efficiency snow removal can be achieved by utilizing the distributed energy storage unit 203 in a large-scale photovoltaic power plant, and snow removal can be individually controlled for each photovoltaic panel 201 according to the snow accumulation conditions, thereby restoring the power generation capacity of the photovoltaic power plant with the least energy consumption.

[0066] Example 2

[0067] This embodiment introduces a snow removal method based on distributed energy storage vibration and photovoltaic panel heating. The concept is the same as that of embodiment 1. On the one hand, it is designed for snow removal of a single panel, and on the other hand, it uses the local power supply of the distributed energy storage unit 203 to reversely discharge the photovoltaic panel 201 to achieve heating. Specifically:

[0068] A vibration module 205 is installed on each photovoltaic panel 201 , and each photovoltaic panel 201 is connected to a corresponding distributed energy storage unit 203 via a reverse power supply circuit 204 .

[0069] Snow removal methods include:

[0070] Controlling each vibration module 205 to work or shut down respectively; and,

[0071] The distributed energy storage unit 203 is controlled by the reverse power supply circuit 204 of each photovoltaic panel 201 to discharge or stop discharging to each connected photovoltaic panel 201 respectively.

[0072] For the issuance of control instructions, the reverse power supply circuit 204 and the vibration module 205 of each photovoltaic panel 201 can be connected to the same IoT communication module 200, and the corresponding control instructions can be received through the IoT communication module 200. For example, the vibration module 205 adjusts the working state in response to the first instruction received by the IoT communication module 200. The reverse power supply circuit 204 controls the distributed energy storage unit 203 to discharge or stop discharging to the photovoltaic panel 201 in response to the second instruction received by the IoT communication module 200.

[0073] In addition, the photovoltaic panel 201 may be controlled to charge the distributed energy storage unit 203. For example, a third control instruction is sent to the reverse power supply circuit 204 of the target photovoltaic panel 201, and the reverse power supply circuit 204 controls the photovoltaic panel 201 to charge or stop charging the distributed energy storage unit 203 in response to the third instruction received by the Internet of Things communication module 200.

[0074] Usually, a power optimizer 202 is connected to the photovoltaic panel 201. The power optimizer 202 can obtain the power generation voltage and current of the photovoltaic panel 201, and can reflect the power generation voltage and current of the photovoltaic panel 201 in its own working parameters during the maximum power point tracking process. If the photovoltaic panel 201 is covered with snow, the power generation power is low, and the power generation voltage and current are reduced accordingly. The snow accumulation state of the photovoltaic panel 201 can be reflected by reporting the working parameters through the power optimizer 202. In addition, the power generation power of the photovoltaic panel 201 is low, and the electric energy stored in the distributed energy storage unit 203 must be reduced accordingly. The snow accumulation state of the photovoltaic panel 201 can also be reflected by reporting the working parameters (such as voltage) through the distributed energy storage unit 203.

[0075] Therefore, snow removal methods also include:

[0076] The operating parameters of the power optimizer 202 and the distributed energy storage unit 203 are reported. The reporting can be performed with the aid of the above-mentioned Internet of Things communication module 200, that is, the Internet of Things communication module 200 is also connected to the power optimizer 202 and the distributed energy storage unit 203 respectively. The reporting frequency can be regular reporting or on-demand reporting. For example, the Internet of Things communication module 200 reports the operating parameters of the distributed energy storage unit 203 and / or the power optimizer 202 regularly, or reports in response to the received fourth instruction.

[0077] Example 3

[0078] This embodiment introduces a snow removal system based on distributed energy storage vibration and photovoltaic panel heating. Figure 1 As shown, the system includes at least one set of snow removal devices described in Example 1, and usually one set of snow removal devices is installed on each photovoltaic panel 201. The system also includes a control center 301, which can be one or more control centers 301. One control center 301 is connected to a large number of snow removal devices through the Internet of Things communication modules 200 of the snow removal devices.

[0079] The control center 301 implements distributed snow removal control for each photovoltaic panel 201, and needs to first understand the snow accumulation status of each photovoltaic panel 201. Usually, in a specific season, the working parameters of the power optimizer 202 and the distributed energy storage unit 203 reported by the snow removal device can reflect the snow accumulation status of the photovoltaic panel 201 to a certain extent, but the snow accumulation status of the photovoltaic panel 201 can also be comprehensively judged in combination with meteorological data. Therefore, the control center 301 can also connect to the meteorological station 303 to obtain meteorological data, such as weather forecast, temperature, snowfall area, snowfall degree, etc., to comprehensively judge the snow accumulation conditions on the photovoltaic panel 201 site. Then, according to the snow accumulation conditions of each photovoltaic panel 201, the control center 301 performs distributed on-demand control of the working status of each snow removal device.

[0080] Example 4

[0081] This embodiment introduces the snow removal method of the snow removal system. The control center 301 performs distributed snow removal control on each photovoltaic panel 201, and therefore needs to understand the working parameters reported by each group of snow removal devices.

[0082] The control center 301 obtains the working parameters reported by each distributed energy storage unit 203 and the working parameters reported by each power optimizer 202 respectively.

[0083] The control center 301 determines the real-time snow accumulation status of each photovoltaic panel 201 based on the acquired data. The data acquired by the control center 301 here may be the working parameters reported by the power optimizer 202 and the distributed energy storage unit 203 in the aforementioned steps, and may further include meteorological data, and even data collected by temperature and humidity sensors installed in the photovoltaic power plant. The determined snow accumulation status may be a snow accumulation level determined based on the acquired data to indicate the degree of snow accumulation, and it may be set at which snow accumulation level snow removal is required, and snow removal is not required when the snow accumulation level is not reached.

[0084] The control center 301 sends the first instruction and the second instruction to the vibration module 205 and the reverse power supply circuit 204 corresponding to each photovoltaic panel 201 whose snow accumulation status indicates that snow removal is required, so as to start the vibration module 205 and control the distributed energy storage unit 203 to discharge to the photovoltaic panel 201.

[0085] As snow removal proceeds, the power generation power of the photovoltaic panel 201 can be restored after snow removal, and the working parameters of the power optimizer 202 and the distributed energy storage unit 203 connected thereto will change accordingly. The control center 301 can analyze the latest snow accumulation status of the photovoltaic panel 201 through the reported working parameters.

[0086] The control center 301 sends the first instruction and the second instruction to the vibration module 205 and the reverse power supply circuit 204 corresponding to each photovoltaic panel 201 whose snow accumulation status indicates that snow removal is no longer required, so as to shut down the vibration module 205 and control the distributed energy storage unit 203 to stop discharging to the photovoltaic panel 201.

[0087] It should be noted that the control center 301 controls the operation or shutdown of the snow removal device in a real-time dynamic process, and each group of snow removal devices is independently controlled. That is, when a group / some snow removal devices are controlled to operate, another group / some other snow removal devices may be controlled to shut down at the same time.

[0088] Through the above method, distributed snow removal of a large number of photovoltaic panels 201 can be achieved, thereby restoring the power generation power of the photovoltaic panels 201 with minimum energy consumption and highest efficiency, thereby maximizing economic benefits.

[0089] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
