Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation monitoring, and in particular to a method, system and device for controlling power generation of cadmium telluride power generation glass of a solar car. Background Art

[0002] Solar cars, which use photovoltaic power generation and energy storage, can effectively solve the energy crisis and alleviate environmental pressures. However, existing solar cars have a problem: due to the low conversion rate of solar panels, the electricity generated by a fixed area of ​​the car surface is often insufficient to meet the needs of vehicle use.

[0003] To address this issue, integrated CdTe solar panels can be attached to the vehicle's exterior. Each facade can be configured with a CdTe panel, depending on its size, for a total of N panels. The power generation system then uses these panels to charge the vehicle's onboard battery. However, conventional high-power DC-DC controllers, designed for large-scale photovoltaic panels on a uniform surface, require high power consumption, consume high power during DC-DC operation, have low conversion efficiency, and are inherently expensive. Therefore, if conventional centralized control is employed for CdTe solar panels on a vehicle, the varying amounts of light received by the panels on different facades will directly reduce the CdTe panel's photoelectric conversion efficiency. As the number N increases, the overall efficiency of the power generation system becomes significantly lower, rendering it completely unsuitable. Summary of the Invention

[0053] Reference Figures 1 to 4To address the problem that conventional high-power DC / DC controllers cannot meet the power generation requirements of large-scale photovoltaic modules on a uniform plane, the present invention provides a method for controlling the power generation of CdTe power generation glass on a solar vehicle. In this embodiment, CdTe power generation glass is deployed on a vehicle to meet the power supply requirements of the solar vehicle. Furthermore, multiple independently controllable integrated power generation units are provided based on the deployment information of the CdTe power generation glass. The power generation status of each integrated power generation unit is precisely controlled to ensure the stability of the CdTe power generation glass under power supply conditions. This effectively meets the photovoltaic conversion power supply requirements of the solar vehicle. This effectively addresses the problem that conventional high-power DC / DC controllers cannot meet the power generation requirements of CdTe power generation glass on a uniform plane.

[0054] Specifically, in a first aspect, the present invention provides a method for controlling power generation using cadmium telluride (CTE) solar-powered glass in a solar vehicle. The method comprises: obtaining design information of a target vehicle and CTE CTE glass layout information to identify at least one integrated power generation unit, thereby facilitating subsequent classification of photoelectric conversion efficiency and integrated energy storage. Real-time data information for each integrated power generation unit is then collected and acquired in real time, thereby determining the real-time status of each integrated power generation unit. Output feedback information for each integrated power generation unit is then determined based on the real-time status and data of each integrated power generation unit, ultimately determining the photoelectric conversion status and efficiency of each integrated power generation unit. Rectification operation information for each integrated power generation unit is then generated based on the output feedback information and real-time status of each integrated power generation unit to ensure stable output from each integrated power generation unit. Finally, the output status of each integrated power generation unit is adjusted based on the rectification operation information, and the adjusted output status of each integrated power generation unit is then stored and output. In this embodiment, CdTe solar panels are deployed on a vehicle to meet the power supply needs of a solar vehicle. Multiple individually controllable integrated power generation units are also configured based on the CdTe panels' layout information. This allows for precise control of the power generation of each integrated unit, ensuring the stability of the CdTe panels under power conditions. This effectively meets the photovoltaic power conversion needs of the solar vehicle and addresses the inability of conventional high-power DC / DC controllers to meet the power generation requirements of the CdTe panels for large-scale photovoltaic modules on a uniform plane. In this embodiment, it should be noted that each integrated power generation unit includes: at least one CdTe panel exposed to the same light intensity, which can be adjacent panels on the same side of the vehicle or a single panel; and a control subunit electrically connected to the panels exposed to the same light intensity and configured to control the photovoltaic conversion of the panels under the same light intensity. Specifically, the control subunit includes a switch Q, a high-frequency, low-resistance inductor L, a low-resistance diode D, and a high-frequency, low-resistance capacitor C. The switch Q is connected to the output terminal of the current power generation integrated unit. When the switch Q is on, the input voltage Vin of the current power generation integrated unit is supplied to the power load through the high-frequency, low-resistance inductor L. Current increases linearly in the high-frequency, low-resistance inductor L, and electrical energy is stored in the high-frequency, low-resistance inductor L. When the switch Q is off, the energy in the high-frequency, low-resistance inductor L is released through the low-resistance diode D, continuing to supply current to the power load, thereby converting the input DC voltage into a lower, stable output DC voltage. Furthermore, the output voltage can be adjusted by controlling the switch's duty cycle (the ratio of the on-time to the switching period).That is, the larger the duty cycle, the higher the output voltage, and vice versa. The switch Q is connected to the output terminal of the current power generation integrated unit. The switch Q controls current conduction and cutoff, and can also adjust the duty cycle. The high-frequency, low-resistance inductor L is electrically connected to the output terminal of the current power generation integrated unit. The high-frequency, low-resistance inductor L is used for filtering and energy storage and release. When the switch Q is on, the high-frequency, low-resistance inductor L rectifies the input current, converting electrical energy into magnetic field energy for storage. When the switch Q is off, the stored magnetic field energy is converted back into electrical energy and released to the load via the low-resistance diode D, thereby smoothing the output current and reducing output current ripple. A low-resistance diode D is electrically connected to the switch Q and the high-frequency low-resistance inductor L. This low-resistance diode provides unidirectional freewheeling. That is, when the switch Q is off, it provides a current path for the energy stored in the high-frequency low-resistance inductor L, allowing it to continue releasing energy to the load, ensuring load current continuity and preventing excessive reverse electromotive force generated by the inductor's sudden power outage, thereby protecting other components in the circuit. Furthermore, the unidirectional conductivity of the low-resistance diode D prevents current from flowing back into the power supply when the switch Q is on. Current is only allowed to flow from the power supply to the high-frequency low-resistance inductor L and the power load when the high-frequency low-resistance inductor L is storing energy, and from the high-frequency low-resistance inductor L to the power load when energy is released, thus maintaining the correct current flow in the circuit. A high-frequency low-resistance capacitor C is electrically connected to the low-resistance diode D and the switch Q. This high-frequency low-resistance capacitor C is used for buffering and voltage stabilization. Specifically, the high-frequency low-resistance capacitor C is primarily used to filter out high-frequency ripple in the output voltage Vin, making the output voltage smoother and more stable. In addition, during circuit transients, such as when the load current suddenly increases or decreases, the capacitor can temporarily provide or absorb part of the current, buffer voltage changes, maintain relative stability of the output voltage, and ensure the normal operation of the load equipment.

[0055] In this embodiment, to ensure the accuracy of the real-time status acquisition of each power generation integrated unit, the method for determining the real-time status of each power generation integrated unit includes: real-time acquisition of the output voltage or current value of the cadmium telluride power generation glass in each power generation integrated unit to obtain multiple voltage sampling values ​​or current sampling values; based on the multiple voltage sampling values ​​or current sampling values ​​and in combination with the sampling period, determining the effective sampling value of each power generation integrated unit; and determining the real-time status of each power generation integrated unit based on the effective sampling value of each power generation integrated unit. In other words, valid data screening criteria are established in advance based on the sampling period of each power generation integrated unit, and valid sampling values ​​are then determined based on the valid data screening criteria. To facilitate understanding of how effective sampling is performed, the following description is provided. Specifically, the method for determining the real-time status of each power generation integrated unit further includes: obtaining multiple voltage sampling values ​​X or multiple current sampling values ​​Y; calculating the average value of the multiple voltage sampling values ​​X or multiple current sampling values ​​Y according to the acquisition and calculation cycle to determine the acquisition and calculation average value; setting filtering information based on the model and specifications of the cadmium telluride power generation glass in each power generation integrated unit and in combination with the acquisition and calculation average value; and then comparing the filtering information with the voltage sampling values ​​X or multiple current sampling values ​​Y of the same subsequent sampling cycle to determine the effective sampling value in each power generation integrated unit. That is, based on the effective data screening standard, the output voltage or current that meets the energy storage requirements is determined to ensure that the real-time status of each power generation integrated unit can be detected.

[0056] To facilitate understanding of how to determine the effective sampling value of cadmium telluride power generation glass, the following example is provided. In one feasible implementation, voltage filtering and current filtering are performed independently by their respective arrays. That is, independent filtering can be performed as follows.

[0057] Specifically, ① the voltage sampling value X or the current sampling value Y is entered into the n-order array An in each calculation cycle, and is shifted right from 1 to n. When running for the first time, the following filtering operation is started after n calculation cycles;

[0058] ②In each calculation cycle, the average value is calculated. The calculation formula of the average value W is as follows:

[0059] ;

[0060] ③ In each calculation cycle, the new sample value X or Y is compared with the average value W. If it is greater than or less than m times the average value, it is considered a bad value and does not enter the array An. An remains the last value; among them, n and m are natural numbers, selected according to the debugging situation.

[0061] In this embodiment, the method for generating rectification operation information for each integrated power generation unit includes: determining output feedback information for each integrated power generation unit based on the sampled effective value of each integrated power generation unit; and then adjusting the capacitor duty cycle disturbance based on the output feedback information of each integrated power generation unit. Specifically, the output state of each integrated power generation unit can be adjusted by adjusting the duty cycle and PWM state of the switch tube Q, thereby facilitating subsequent precise control of energy storage. Specifically, the output energy storage stage of each integrated power generation unit is determined based on the output state of each integrated power generation unit; and then, based on the output energy storage stage of each integrated power generation unit, integrated energy storage can be performed via the battery management board.

[0062] It should be noted that the energy storage state of each power generation integrated unit can be divided into: charging state and freewheeling state.

[0063] When in the charging state, the low-resistance diode D is not conducting and is in the reverse cutoff state; the output of each power generation integrated unit forms a loop with the switch tube Q, the high-frequency low-resistance inductor L, and the high-frequency low-resistance capacitor C; at this time, according to the current-voltage formula of the inductor:

[0064] Formula 1;

[0065] At this point, integrating Equation 1 yields Equation 2:

[0066] Formula 2;

[0067] It is then known that during the entire charging phase, the voltage change across the inductor is expressed as:

[0068] Formula 3;

[0069] Therefore, when the duration of the charging phase is Ton, combining Equation 2 and Equation 3, the increase in the inductor current is obtained as Equation 4:

[0070] Formula 4.

[0071] After the charging phase is completed, the switch tube Q is turned off and the entire circuit is in the freewheeling state. At this time, the low-resistance diode D is normally conducting, and the circuit is composed of a high-frequency low-resistance inductor L, a high-frequency low-resistance capacitor C, a voltage load resistor, and a low-resistance diode D. During the freewheeling phase, the energy of the entire circuit is provided by the high-frequency low-resistance inductor L. The current flows out of the high-frequency low-resistance inductor L, passes through the high-frequency low-resistance capacitor C, the voltage load resistor, and finally flows into the other end of the high-frequency low-resistance inductor L through the low-resistance diode D. The voltage change across the high-frequency low-resistance inductor L during the entire freewheeling phase is:

[0072] Formula 5;

[0073] When the duration of the freewheeling phase is Toff, the reduction in inductor current can be obtained as follows according to Formula 2:

[0074] Formula 6;

[0075] According to the volt-second balance principle, the increase and decrease of the inductor current in one cycle are equal in value, that is:

[0076] Formula 7;

[0077] That is, the energy storage state of each power generation integrated unit can be determined based on equations 1 to 7 and in conjunction with real-time acquisition of the output of each power generation integrated unit.

[0078] In a second aspect, the present invention further provides a cadmium telluride power generation glass power generation control system for a solar car, which adopts a cadmium telluride power generation glass power generation control method for a solar car described in any one of the first aspects, and the control system further includes: a control subunit is a photovoltaic inverter.

Examples of communication networks include a local area network ("LAN"), a wide area network ("WAN"), an internet (e.g., the Internet), and a peer-to-peer network (e.g., an ad hoc peer-to-peer network), as well as any currently known or later developed network.
