Description

Technical Field

[0001] The present invention belongs to the field of capacitor energy storage management, and specifically relates to a supercapacitor energy storage management method, system and medium based on meteorological data. Background Art

[0002] Supercapacitors are electrochemical devices that can quickly store and supply high-power electricity and cycle a large number of times without showing performance degradation. As a new generation of energy storage media, supercapacitors have many advantages such as high number of cycles, short charge and discharge time, high power density, stable working performance, and environmental friendliness. They are very suitable for many occasions such as high-frequency, large-current rapid charging and discharging, and energy buffering and reuse.

[0003] Under the current technological background, most energy storage devices in the energy storage industry have electrical safety and system safety issues, and safety accidents frequently occur due to the decline in battery performance during battery charging. In addition, unreasonable installation positions of supercapacitors may cause problems such as electrolyte leakage, which will damage the structural performance of the capacitor. High temperature and high humidity environments are also prone to damage. Moreover, when supercapacitor cells leave the factory, they cannot be completely consistent in terms of initial capacity, equivalent internal resistance, self-discharge rate and leakage current.

[0004] To this end, the present invention proposes a supercapacitor energy storage management method, system and medium based on meteorological data. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a supercapacitor energy storage management method, system and medium based on meteorological data.

[0006] The technical problems to be solved by the present invention are:

[0007] How to achieve intelligent state management of supercapacitors based on multi-source data.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] In a first aspect, a supercapacitor energy storage management method based on meteorological data comprises the following steps:

[0010] Step S1, demarcating candidate deployment areas for capacitor energy storage units based on the location of the power plant;

[0011] Step S2: Distribute a number of meteorological monitoring devices in the candidate deployment area to obtain periodic meteorological data of the candidate deployment area;

[0012] Step S3, comprehensively evaluating the deployment environment and wind and solar power generation environment of the candidate deployment area, and selecting a deployment location for the capacitor energy storage unit based on the evaluation results;

[0013] Step S4, monitoring the operating status of each supercapacitor module in the capacitor energy storage unit by a capacitor monitoring device to obtain capacitance operating data of each supercapacitor module in the capacitor energy storage unit;

[0014] Step S5: Comprehensively analyze the operating status of the capacitor energy storage unit, and perform balancing and intervention work on the capacitor energy storage unit according to the analysis results of the operating status.

[0015] Furthermore, the periodic meteorological data includes real-time temperature, real-time humidity, real-time wind speed, real-time solar irradiance and effective sunshine duration at each meteorological monitoring device in the candidate deployment area;

[0018] Take the center of the power plant area as the center of the circle, and draw a line segment across the power plant area through the center of the circle, ensuring that the endpoints of the line segment coincide with the edge of the power plant area.

[0019] The corresponding line segment is rotated once and the maximum length of the line segment is recorded as the area diameter. A circular area is constructed according to the area center and the area diameter as the power plant influence area.

[0020] Construct alternative deployment areas for capacitor storage units based on the power plant's impact area and critical transmission distance.

[0021] Furthermore, the construction process of the candidate deployment area is as follows:

[0023] A circular area is constructed according to the center of the area and the diameter of the subsidiary area as the power plant subsidiary area, and the power plant impact area in the power plant subsidiary area is eliminated to obtain the alternative deployment area.

[0024] Furthermore, in step S2, the recording process of the effective sunshine duration is specifically as follows:

[0026] Compare the real-time solar irradiance of the monitoring area with the solar irradiance threshold;

[0027] When the real-time solar irradiance in the monitoring area is greater than or equal to the solar irradiance threshold, the current moment is recorded as the effective sunshine duration;

[0028] When the real-time solar irradiance in the monitoring area is less than the solar irradiance threshold, the current moment is recorded as invalid sunshine duration.

[0029] Furthermore, in step S3, the deployment site selection process of the capacitor energy storage unit specifically includes:

[0032] Compare the environmental suitability index at the meteorological monitoring equipment with the critical environmental suitability index;

[0033] If the environmental suitability index is less than the critical environmental suitability index, the corresponding meteorological monitoring equipment will be marked as an unsuitable deployment location;

[0034] If the environmental suitability index is greater than or equal to the critical environmental suitability index, obtain the wind / solar compensation index at each meteorological monitoring device in the candidate deployment area, and compare the wind / solar compensation index at the meteorological monitoring device with the wind / solar compensation threshold;

[0035] If the wind-solar compensation index is less than the first wind-solar compensation threshold, the mark type at the corresponding meteorological monitoring equipment is recorded as a third-level alternative deployment location;

[0036] If the wind-solar compensation index is greater than or equal to the first wind-solar compensation threshold and less than the second wind-solar compensation threshold, the mark type at the corresponding meteorological monitoring equipment is recorded as a secondary alternative deployment location;

[0037] If the wind-solar compensation index is greater than or equal to the second wind-solar compensation threshold, the mark type at the corresponding meteorological monitoring equipment is recorded as a first-level alternative deployment location;

[0038] Among them, the values ​​of the first wind-solar compensation threshold and the second wind-solar compensation threshold are both greater than zero, the first wind-solar compensation threshold is less than the second wind-solar compensation threshold, the deployment priority of the first-level alternative deployment location is higher than the deployment priority of the second-level alternative deployment location, and the deployment priority of the second-level alternative deployment location is higher than the deployment priority of the third-level alternative deployment location;

[0039] Install capacitor energy storage units and supporting facilities according to the marking type of the alternative deployment location;

[0040] If the mark type at any meteorological monitoring device is a first-level alternative deployment location, the first-level alternative deployment location is preferably the installation location of the capacitor energy storage unit, and the number of modules of the supercapacitor module in the corresponding capacitor energy storage unit is the third module number;

[0041] If there is no meteorological monitoring device with a mark type of the first-level alternative deployment location, and the mark type of any meteorological monitoring device is the second-level alternative deployment location, then the second-level alternative deployment location is preferably the installation location of the capacitor energy storage unit, and the module number of the supercapacitor module in the corresponding capacitor energy storage unit is the second module number;

[0042] If there is no mark type at the meteorological monitoring equipment that is a first-level alternative deployment location or a second-level alternative deployment location, the third-level alternative deployment location is preferably the installation location of the capacitor energy storage unit, and the number of modules of the supercapacitor module in the corresponding capacitor energy storage unit is the first number of modules; wherein, the third number of modules is greater than the second number of modules, and the second number of modules is greater than the first number of modules.

[0043] Furthermore, in step S5, the process of analyzing the operating status of the capacitor energy storage unit specifically includes:

[0044] Obtaining the module voltage of the supercapacitor module in the capacitor energy storage unit and comparing the module voltage with the safety protection voltage;

[0045] If the module voltage is greater than the safety protection voltage, a first alarm signal is generated;

[0046] If the module voltage is less than or equal to the safety protection voltage, the module current of the corresponding supercapacitor module is obtained and compared with the safety protection current;

[0047] If the module current is greater than the safety protection current, a second alarm signal is generated;

[0048] If the module current is less than or equal to the safety protection current, the module temperature of the corresponding supercapacitor module is obtained and compared with the safety protection temperature;

[0049] If the module temperature is higher than the safety protection temperature, a third alarm signal is generated;

[0050] If the module temperature is lower than or equal to the safety protection temperature, no operation will be performed.

[0051] Furthermore, in step S5, the control work for the capacitor energy storage unit specifically includes:

[0053] When the value of the module voltage difference is greater than or equal to the critical voltage difference, the supercapacitor module in the capacitor energy storage unit is actively voltage-controlled, that is, the gap between the supercapacitor modules is narrowed;

[0054] When the first alarm signal is received, the capacitor energy storage unit performs voltage regulation on the supercapacitor module;

[0055] When the second alarm signal is received, the capacitor energy storage unit regulates the current of the supercapacitor module;

[0056] When the third alarm signal is received, the temperature control device built into the capacitor energy storage unit is started to perform temperature control;

[0057] When the startup time of the temperature control equipment reaches the critical time, if the alarm signal is still not released, the corresponding capacitor energy storage unit will be controlled to exit operation, and staff will be arranged to perform equipment maintenance work.

[0058] Secondly, the supercapacitor energy storage management system based on meteorological data includes a regional division module, a capacitor energy storage unit, meteorological monitoring equipment, an environmental assessment module, a capacitor monitoring device, a safety assessment module, and a countermeasure execution module.

[0063] The safety assessment module is used to perform a safety assessment on the operating state of the capacitor energy storage unit;

[0064] The countermeasure execution module is used to perform balancing and intervention work on the capacitor energy storage unit.

[0065] In a third aspect, a computer-readable storage medium is also provided, on which a computer program is stored. When the program is executed by a processor, a supercapacitor energy storage management method based on meteorological data is implemented.

[0066] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0076] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0077] Example 1: Please refer to Figure 1-Figure 5 As shown, the technical solution provided by the present invention is: a supercapacitor energy storage management method based on meteorological data, the method is as follows:

[0078] Step S1, demarcating candidate deployment areas for capacitor energy storage units based on the location of the power plant;

[0079] Specifically, the capacitor energy storage unit is connected to the power plant via a transmission line. The power generation mode of the power plant includes wind power generation, hydropower generation and photovoltaic power generation. In this embodiment, photovoltaic power generation is preferably used as the power generation mode of the power plant.

[0080] In step S1, the process of demarcating candidate deployment areas specifically includes:

[0081] Step S101, as Figure 2 As shown in the figure, the center of the power plant area is taken as the center of the circle, and a line segment is drawn through the center of the circle across the power plant area, ensuring that the endpoints of the line segment coincide with the edge line of the power plant area.

[0082] Step S102: Rotate the corresponding line segment once and record the maximum length of the line segment as the area diameter. Construct a circular area as the power plant influence area based on the area center and the area diameter.

[0083] Step S103: constructing a candidate deployment area for the capacitor storage unit based on the power plant influence area and the critical transmission distance; wherein the radius of the candidate deployment area minus the radius of the power plant influence area is the critical transmission distance;

[0084] See also Figure 3 In step S103, the process of constructing the candidate deployment area is as follows:

[0085] Obtain the regional diameter QDE and critical transmission distance LL of the power plant's influence area, and calculate the subsidiary area diameter QDT according to the formula. The formula is as follows:

[0086] QDT=QDE+LL×2;

[0087] like Figure 3 As shown, a circular area is constructed as the power plant's affiliated area based on the area center and the diameter of the affiliated area, and the power plant's influence area in the power plant's affiliated area is eliminated to obtain the alternative deployment area;

[0088] It can be understood that the intersection of the alternative deployment area and the power plant influence area is an empty set, and the union of the alternative deployment area and the power plant influence area is the power plant affiliated area.

[0089] Step S2: Distribute a number of meteorological monitoring devices in the candidate deployment area to obtain periodic meteorological data of the candidate deployment area;

[0090] It should be noted that the periodic meteorological data includes the real-time temperature, real-time humidity, real-time wind speed, real-time solar irradiance, and effective sunshine duration at each meteorological monitoring device in the candidate deployment area. The monitoring period of the periodic meteorological data is 15 minutes.

[0091] In step S2, the meteorological monitoring equipment includes a thermometer, a hygrometer, an anemometer, and a spectrometer. In actual operation, the thermometer is used to monitor real-time temperature, the hygrometer is used to monitor real-time humidity, the anemometer is used to monitor real-time wind speed, and the spectrometer is used to monitor real-time solar irradiance. Solar irradiance is a parameter used to quantitatively describe solar radiation. It is the radiant energy per unit area per unit time that reaches the solid Earth's surface after being absorbed, scattered, and reflected by the atmosphere. The unit of solar irradiance is watts per square meter.

[0092] In step S2, the recording process of effective sunshine duration is as follows:

[0093] Obtaining a solar irradiance threshold value pre-stored in a database. In this embodiment, the working solar irradiance of the small solar panel is preferably used as the solar irradiance threshold value, that is, the startup solar irradiance of the small solar panel is used as the first solar irradiance threshold value, and the critical solar irradiance of the small solar panel is used as the second solar irradiance threshold value;

[0094] Compare the real-time solar irradiance of the monitoring area with the solar irradiance threshold;

[0095] When the real-time solar irradiance in the monitoring area is greater than or equal to the solar irradiance threshold, the current moment is recorded as the effective sunshine duration;

[0096] When the real-time solar irradiance in the monitoring area is less than the solar irradiance threshold, the current moment is recorded as invalid sunshine duration;

[0097] It is understandable that the effective sunshine duration is used to reflect the photovoltaic power generation environment of the alternative deployment area. The longer the effective sunshine duration, the more photovoltaic power generation.

[0098] Step S3, comprehensively evaluating the deployment environment and wind and solar power generation environment of the candidate deployment area, and selecting a deployment location for the capacitor energy storage unit based on the evaluation results;

[0099] In step S3, the deployment environment evaluation process of the candidate deployment area specifically includes:

[0101] The environmental suitability index SYi at the meteorological monitoring equipment is calculated according to the formula. The specific formula is as follows:

[0102] ;

[0103] Among them, e is a natural constant, a1 and a2 are weight coefficients with fixed values, the values ​​of a1 and a2 are both greater than zero, a1 is the temperature difference weight, a2 is the humidity weight, BT is the rated operating temperature of the capacitor energy storage unit, and BW is the rated operating humidity of the capacitor energy storage unit. It can be understood that the environmental suitability index is used to reflect the degree of adaptability between the environment at the meteorological monitoring equipment and the capacitor energy storage unit.

[0104] In step S3, the environmental assessment process of wind and solar power generation in the candidate deployment area specifically includes:

[0105] Obtain the real-time wind speed SFir, real-time solar irradiance SZir, and effective sunshine duration RZi at each meteorological monitoring device in the candidate deployment area;

[0106] The wind and solar compensation index FGi at the meteorological monitoring equipment is calculated according to the formula. The specific formula is as follows:

[0107] ;

[0108] Among them, b1 and b2 are weight coefficients with fixed values, b1 is the weight of wind power resources, and b2 is the weight of photovoltaic resources.

[0109] In step S3, the deployment site selection process of the capacitor energy storage unit is as follows:

[0110] Obtaining an environmental suitability index at each meteorological monitoring device in the candidate deployment area, and comparing the environmental suitability index at the meteorological monitoring device with a critical environmental suitability index;

[0111] If the environmental suitability index is less than the critical environmental suitability index, the corresponding meteorological monitoring equipment will be marked as an unsuitable deployment location;

[0112] If the environmental suitability index is greater than or equal to the critical environmental suitability index, obtain the wind / solar compensation index at each meteorological monitoring device in the candidate deployment area, and compare the wind / solar compensation index at the meteorological monitoring device with the wind / solar compensation threshold;

[0113] If the wind-solar compensation index is less than the first wind-solar compensation threshold, the mark type at the corresponding meteorological monitoring equipment is recorded as a third-level alternative deployment location;

[0114] If the wind-solar compensation index is greater than or equal to the first wind-solar compensation threshold and less than the second wind-solar compensation threshold, the mark type at the corresponding meteorological monitoring equipment is recorded as a secondary alternative deployment location;

[0115] If the wind-solar compensation index is greater than or equal to the second wind-solar compensation threshold, the mark type at the corresponding meteorological monitoring equipment is recorded as a first-level alternative deployment location;

[0116] Among them, the values ​​of the first wind-solar compensation threshold and the second wind-solar compensation threshold are both greater than zero, the first wind-solar compensation threshold is less than the second wind-solar compensation threshold, the deployment priority of the first-level alternative deployment location is higher than the deployment priority of the second-level alternative deployment location, and the deployment priority of the second-level alternative deployment location is higher than the deployment priority of the third-level alternative deployment location;

[0117] Install the capacitor energy storage unit and supporting facilities according to the marking type of the alternative deployment location. The installation work specifically includes:

[0118] See also Figure 4 As shown, the capacitor energy storage unit is designed in a container-type shape and is composed of a number of supercapacitor modules;

[0119] If the mark type at any meteorological monitoring device is a first-level alternative deployment location, the first-level alternative deployment location is preferably the installation location of the capacitor energy storage unit, and the number of modules of the supercapacitor module in the corresponding capacitor energy storage unit is the third module number;

[0120] If there is no meteorological monitoring device with a mark type of the first-level alternative deployment location, and the mark type of any meteorological monitoring device is the second-level alternative deployment location, then the second-level alternative deployment location is preferably the installation location of the capacitor energy storage unit, and the module number of the supercapacitor module in the corresponding capacitor energy storage unit is the second module number;

[0121] If there is no meteorological monitoring equipment at which the marking type is a first-level alternative deployment location or a second-level alternative deployment location, the third-level alternative deployment location is preferably the installation location of the capacitor energy storage unit, and the module number of the supercapacitor module in the corresponding capacitor energy storage unit is the first module number;

[0122] The third module number is greater than the second module number, and the second module number is greater than the first module number;

[0123] During specific implementation, the installation of wind power and photovoltaic equipment can also be carried out according to the marking type of the alternative deployment location. Specifically, small wind power generation equipment or photovoltaic power generation equipment is installed at the first-level alternative deployment location and the second-level alternative deployment location. Wind power generation or photovoltaic power generation is used to supply power to meteorological monitoring equipment and capacitor monitoring equipment.

[0124] Step S4, monitoring the operating status of each supercapacitor module in the capacitor energy storage unit by a capacitor monitoring device to obtain capacitance operating data of each supercapacitor module in the capacitor energy storage unit;

[0125] In step S4, the capacitor operation data includes the module voltage, module current and module block temperature of the supercapacitor module, wherein the module voltage is the real-time voltage of the supercapacitor module, the module current is the real-time current of the supercapacitor module, and the module block temperature is the maximum value of the module surface temperature of the supercapacitor module.

[0126] Step S5, comprehensively analyzing the operating status of the capacitor energy storage unit, and performing balancing and intervention work on the capacitor energy storage unit according to the analysis results of the operating status;

[0127] In step S5, the process of analyzing the operating status of the capacitor energy storage unit specifically includes:

[0128] Obtaining the module voltage of the supercapacitor module in the capacitor energy storage unit and comparing the module voltage with the safety protection voltage;

[0129] If the module voltage is greater than the safety protection voltage, a first alarm signal is generated;

[0130] If the module voltage is less than or equal to the safety protection voltage, the module current of the corresponding supercapacitor module is obtained and compared with the safety protection current;

[0131] If the module current is greater than the safety protection current, a second alarm signal is generated;

[0132] If the module current is less than or equal to the safety protection current, the module temperature of the corresponding supercapacitor module is obtained and compared with the safety protection temperature;

[0133] If the module temperature is higher than the safety protection temperature, a third alarm signal is generated;

[0134] If the module temperature is less than or equal to the safety protection temperature, no operation will be performed;

[0135] Among them, the safety protection voltage, safety protection current and safety protection temperature are pre-stored in the parameter database. In this embodiment, the safety protection voltage, safety protection current and safety protection temperature are set according to the critical voltage, critical current and critical temperature of the supercapacitor module.

[0136] In step S5, the balancing operation for the capacitor energy storage unit specifically includes:

[0137] Obtain the module voltage of the supercapacitor module in the capacitor energy storage unit, traverse and compare to obtain the maximum module voltage and the minimum module voltage in the capacitor energy storage unit, and calculate the module voltage difference of the capacitor energy storage unit by subtracting the minimum module voltage from the maximum module voltage;

[0138] When the value of the module voltage difference is greater than or equal to the critical voltage difference, the supercapacitor modules in the capacitor energy storage unit are actively voltaged, that is, the gap between the supercapacitor modules is narrowed.

[0139] In step S5, the intervention work on the capacitor energy storage unit specifically includes:

[0140] When the first alarm signal is received, the capacitor energy storage unit performs voltage regulation on the supercapacitor module;

[0141] When the second alarm signal is received, the capacitor energy storage unit regulates the current of the supercapacitor module;

[0142] When the third alarm signal is received, the temperature control device built into the capacitor energy storage unit is started to perform temperature control;

[0143] When the startup time of the temperature control equipment reaches 3 minutes, if the alarm signal is still not lifted, the corresponding capacitor energy storage unit will be controlled to exit operation, and staff will be arranged to perform equipment maintenance work.

[0144] In this application, if a corresponding calculation formula appears, the above calculation formula is dimensionless and its numerical calculation is performed. The weight coefficient, proportional coefficient and other coefficients in the formula are set to a result value obtained by quantifying each parameter. Regarding the size of the weight coefficient and the proportional coefficient, as long as it does not affect the proportional relationship between the parameter and the result value, it is acceptable.
