[0021] In the related technology, photovoltaic is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to convert solar radiation energy into electrical energy. It is understandable that there are several photovoltaic modules in the photovoltaic system, and each photovoltaic module is provided with several photovoltaic panels, which convert solar energy into electrical energy through photovoltaic panels. At present, the installation information of photovoltaic is determined based on the meteorological information and longitude and latitude information of the location of the photovoltaic, and the photovoltaic installation is performed based on the installation information. However, during the application process of photovoltaics installed in this way, it will be affected by other factors, resulting in a low solar energy conversion rate. In addition, the current photovoltaic modules will not be adjusted once they are installed, so that photovoltaics cannot effectively adapt to the ever-changing influencing factors in the application scenario, and thus cannot improve the solar energy conversion rate in the installation area.

[0022] In view of this, a data analysis method and system for a photovoltaic system are provided in an embodiment of the present application.

[0025] Figure 1 is an optional flow chart of the data analysis method for a photovoltaic system provided in an embodiment of the present application. Figure 1 The method may include but is not limited to steps S110 to S160: Step S110, obtaining initial parameters of the photovoltaic panels, and obtaining historical meteorological information, longitude and latitude information, and topographic information of a preset photovoltaic installation area; Step S120, generating a photovoltaic installation plan for the preset photovoltaic installation area according to the initial parameters, historical meteorological information, longitude and latitude information, and topographic information, wherein the photovoltaic installation plan includes installation parameters of each photovoltaic module, and the installation parameters include the number of photovoltaic panels in each photovoltaic module and the installation height and installation inclination of each photovoltaic panel; Step S130, collecting the first output electric energy of each photovoltaic module, wherein the photovoltaic modules are installed based on a photovoltaic installation plan; Step S140, obtaining the power consumed and stored by the first load; Step S150, analyzing the power supply status of each photovoltaic module according to the first output power, the first load consumed power and the stored power; Step S160: modifying the photovoltaic installation plan of the preset photovoltaic installation area according to the power supply status.

[0026] In the embodiment of the present application, the initial parameters of the photovoltaic panel include but are not limited to the rated conversion power, rated current and rated voltage of the photovoltaic panel. The historical meteorological information may be meteorological information within a preset time period in a preset photovoltaic installation area, and the meteorological information may be weather forecast information or actual meteorological information, such as meteorological information uploaded on a terminal by a person who is familiar with the actual meteorological information in the preset photovoltaic installation area.

[0027] Specifically, the longitude and latitude information and the topographic information can be obtained through relevant geographic software or websites. The longitude and latitude information can affect the radiation angle and radiation intensity of sunlight. The topographic information includes but is not limited to mountain information, vegetation information, building information and other information. Among them, these topographic information can characterize the degree of blocking of sunlight. For example, in an area with many mountains, in order to increase the exposure time and area of ​​sunlight to photovoltaics, photovoltaics can be set on the top of the mountain or on the east side of the mountain.

[0028] In the embodiment of the present application, the photovoltaic installation scheme can be determined by considering the impact of initial parameters, historical meteorological information, longitude and latitude information, and topographic information on the photovoltaic solar energy conversion rate. Specifically, Figure 2As shown, the process of generating a photovoltaic installation plan for a preset photovoltaic installation area based on initial parameters, historical meteorological information, longitude and latitude information, and topographic information includes but is not limited to the following steps: Step S210, calculating the first conversion efficiency of each photovoltaic panel according to the initial parameters; Step S220: constructing a preset decision model; Step S230: input the first conversion rate, historical meteorological information, longitude and latitude information, and topographic information into a preset decision model, and output a photovoltaic installation plan for a preset photovoltaic installation area.

[0029] It can be understood that, assuming that all sunlight in each photovoltaic panel is directly incident on the surface of the photovoltaic panel, and the duration of the solar panel being irradiated by sunlight is the duration of the visible sun in the area, the conversion efficiency of the photovoltaic panel to solar energy is calculated as the first conversion efficiency. The historical meteorological information, longitude and latitude information, and topographic information are all information corresponding to the preset photovoltaic installation area. For example, when it is necessary to install photovoltaics in the area of ​​Township A, the historical meteorological information, longitude and latitude information, and topographic information are all information in the corresponding area of ​​Township A.

[0030] It can be understood that the preset decision model of this embodiment can be a decision model constructed based on the target optimization function after constructing the target optimization function based on the first conversion rate, historical meteorological information, longitude and latitude information and topographic information. The target optimization function is used to calculate the minimum difference between the total power of the preset photovoltaic installation in the preset photovoltaic installation area and the total power of the preset photovoltaic installation under the influence of historical meteorological information, longitude and latitude information and topographic information, and its formula is as follows: ; In the formula, n represents the number of photovoltaic panels in the preset photovoltaic installation, f(x) represents the first conversion rate of a single photovoltaic panel, α represents the influence coefficient of historical meteorological information on the solar energy conversion of photovoltaic panels in the preset photovoltaic installation area; β represents the influence coefficient of longitude and latitude information on the solar energy conversion of photovoltaic panels in the preset photovoltaic installation area; γ represents the influence coefficient of topographic information on the solar energy conversion of photovoltaic panels in the preset photovoltaic installation area.

[0031] It can be seen from the above formula that all the influence coefficients can be determined by consulting historical data and determining the influence of meteorological information, longitude and latitude information or topographic information in historical data on the solar energy conversion of photovoltaic panels. Specifically, the influence process includes but is not limited to the influence of meteorological information, longitude and latitude information or topographic information on multiple photovoltaic panels in different arrangements, installation angles and installation heights. Specifically, when the target optimization function is calculated multiple times to obtain the minimum difference, the number of photovoltaic panels, arrangement, installation angle and installation height determined at this time can be used as the photovoltaic installation plan output by the preset decision model.

[0032] In the embodiments of the present application, Figure 3 As shown, the process of inputting the first conversion rate, historical meteorological information, longitude and latitude information, and topographic information into the preset decision model and outputting a photovoltaic installation plan for the preset photovoltaic installation area includes but is not limited to the following steps: Step S310, analyzing the light shielding status of the preset photovoltaic installation area according to the latitude and longitude information and the topographic information; Step S320, determining the installation height and installation inclination angle of each photovoltaic panel in each photovoltaic module according to the light shielding state and historical meteorological information; Step S330, adjusting the first conversion rate according to the installation height and the installation inclination angle to obtain a second conversion rate; Step S340: Determine the number of photovoltaic panels in each photovoltaic module according to the second conversion rate.

[0033] It can be understood that the sun's irradiation angle and irradiation time to the earth are different in the areas corresponding to different longitude and latitude information, and the topography corresponding to the topography information in these areas will also have a certain impact on the irradiation process of the photovoltaic panel receiving sunlight, and different meteorological information will also affect the radiation angle of sunlight to the photovoltaic panel to a certain extent. Therefore, this embodiment simulates and analyzes the light shielding state of the area according to the longitude and latitude information and the topography information, and then simulates the installation height and installation inclination of each photovoltaic panel in each photovoltaic module based on the light shielding state combined with historical meteorological information, so that the photovoltaic panels installed based on the installation scheme can receive sunlight more effectively. In addition, since the photovoltaic panels are at different installation angles and different installation heights, the solar light conversion rate corresponding to the photovoltaic panels is also different. Therefore, after determining the installation angle and installation height, this embodiment replaces the first conversion rate with the conversion rate of the panel at the installation angle and the installation height to obtain the second conversion rate. Then, based on the second conversion rate, the number of photovoltaic panels in each photovoltaic module is determined, so that the photovoltaic installation scheme obtained by the decision model can be more in line with the actual photovoltaic installation situation in the current area.

[0034] In the embodiment of the present application, after the photovoltaic installation scheme obtained based on the above steps is used for photovoltaic installation, the embodiment can automatically monitor and adjust the photovoltaic throughout the whole process. It can be understood that the embodiment first obtains all the load status information in the preset photovoltaic installation area, determines the target load and the number of loads in the power supply state according to the load status information, and obtains the electric energy parameters of the target load, and then calculates the electric energy consumption of all loads corresponding to the current photovoltaic according to the electric energy parameters and the number of loads as the first load consumption of electric energy. For example, it is assumed that photovoltaic A is connected to loads B1, B2, B3, B4, B5 and B6. Since these loads may be in working state in a certain period of time, they need to consume a certain amount of electric energy; and some loads will not work in a certain period of time, and will not consume electric energy. For example, when load B2 is used as a backup load for load B1, if load B1 can work normally, load B2 can be in a closed state, that is, in a state of not consuming electric energy. Similarly, assuming that load B4 serves as a backup load for load B2 and load B6 serves as a backup load for load B5, based on this assumption and combined with the load status information, it can be determined that the target loads in the preset photovoltaic installation area that are in a power supply state may be load B1, load B3 and load B5, and the corresponding number of loads is 3. Therefore, after obtaining the power parameters of loads B1, load B3 and load B5, the power consumption of each load can be calculated according to the load parameters, and then combined with the number of loads, the total power consumption in the preset photovoltaic installation area can be determined as the first load power consumption.

[0035] In the embodiment of the present application, after obtaining the power consumed and stored by the first load, as Figure 4 As shown, the process of analyzing the power supply status of each photovoltaic module according to the first output power, the first load consumed power and the stored power includes but is not limited to the following steps: Step S410, obtaining a loss coefficient corresponding to the first output electric energy, wherein the loss coefficient is used to characterize the magnitude of electric energy loss when the output end of the photovoltaic module performs electric energy conversion; Step S420, calculating the second output electric energy according to the loss coefficient and the first output electric energy; Step S430, calculating the total consumed electric energy according to the electric energy consumed by the first load and the stored electric energy; Step S440: determining the power supply status of each photovoltaic module according to the second output power and the total consumed power.

[0036] It is understandable that, because the electric energy output by the photovoltaic panel will be affected by various factors when the photovoltaic converts solar energy, the output voltage thereof will be unstable. Therefore, an inverter module can be set at the voltage output end of the photovoltaic panel in advance to convert the output voltage of the photovoltaic panel through the inverter module, so that a stable voltage can be output to the load or storage module, thereby improving the working stability of the circuit. Specifically, when the inverter module performs voltage conversion, there will be a certain loss in the voltage. Therefore, the present embodiment can determine the corresponding loss coefficient according to the type of the inverter module, and calculate the actual output based on the loss coefficient, so that the calculation result can be more in line with the actual situation.

[0037] It can be understood that the first electric energy involved in this embodiment can be the direct output electric energy of the photovoltaic panel or each photovoltaic module; the second electric energy can be the output electric energy of the photovoltaic panel or photovoltaic module after passing through the inverter module, that is, the electric energy after conversion by the inverter. Specifically, after the photovoltaic panel converts sunlight into electric energy, the electric energy can be directly output to the load, or it can be stored through the storage module. Therefore, this embodiment calculates the total electric energy consumption of the corresponding photovoltaic module according to the electric energy consumed by the first load and the stored electric energy, and then determines the power supply status of each photovoltaic module according to the second output electric energy and the total electric energy consumption. Among them, the power supply status includes but is not limited to the normal power supply status, the warning power supply status, the stable power supply status or the overload power supply status.

[0038] It can be understood that in some embodiments, when the second output power is greater than or equal to the total power consumption, it is determined that the power supply state of the corresponding photovoltaic module is in a normal power supply state; when the second output power is less than the total power consumption, it is determined that the power supply state of the corresponding photovoltaic module is in a warning power supply state. Specifically, when the second output power is greater than or equal to the total power consumption, it can be determined that all photovoltaic panels in the corresponding photovoltaic module are in a normal working state, and there is no faulty photovoltaic panel. Therefore, there is no need to adjust the photovoltaic module in this area. When the second output power is less than the total power consumption, it can be determined that there is an abnormally working photovoltaic panel in the photovoltaic module at this time, thereby reducing the total output power of the photovoltaic module. Therefore, fault warning information can be generated to determine the presence of abnormally working photovoltaic panels through the fault warning information. Exemplarily, when it is determined that there is an abnormally working photovoltaic panel in photovoltaic module A, the real-time output power of each photovoltaic panel in photovoltaic module A can be further collected, and then the working state of the corresponding photovoltaic panel can be analyzed through the real-time output power of each photovoltaic panel, and then the photovoltaic installation plan of the preset photovoltaic installation area can be corrected after the specific photovoltaic panel with fault is determined.

[0039] It can be understood that in other embodiments, when the second output electric energy is greater than or equal to the total electric energy consumption, the power supply state of the corresponding photovoltaic module is determined to be a stable power supply state; when the second output electric energy is less than the total electric energy consumption, the power supply state of the corresponding photovoltaic module is determined to be an overload power supply state. Specifically, when the second output electric energy is greater than or equal to the total electric energy consumption, it can be determined that the electric energy converted by the current photovoltaic module can maintain the normal working process of all current loads. When the second output electric energy is less than the total electric energy consumption, although the current photovoltaic module can provide electric energy for all current loads, the electric energy converted by the current photovoltaic module cannot maintain the normal working state of all loads, that is, the current photovoltaic module needs to overload electric energy conversion for a long time to provide electric energy for all loads. Based on this, in order to maintain the stable operation of all loads and delay the normal working process of the photovoltaic module, this embodiment can adjust the number of photovoltaic modules in the photovoltaic installation scheme or the number of photovoltaic panels in the photovoltaic module so that the staff can adjust the installation state of the corresponding photovoltaic according to the adjusted photovoltaic installation scheme, so that the adjusted photovoltaic can convert more electric energy to maintain the stable operation state of all loads.
