[0059] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and that these embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0060] This embodiment first provides a design method for electrical equipment of a photovoltaic power generation system, which is used to solve the problems of poor adaptability and low efficiency in traditional photovoltaic electrical design, improve design efficiency, and provide basic conditions for the subsequent photovoltaic power generation system to operate efficiently, safely, and stably.

[0061] Figure 1 FIG2 is a schematic diagram of a design method for electrical equipment of a photovoltaic power generation system according to an embodiment of the present invention. The design method for electrical equipment of the photovoltaic power generation system may generally include:

[0062] Step S101 : collecting terrain feature information and meteorological feature information of a location where a photovoltaic power generation system is to be constructed.

[0063] The terrain characteristics of the construction site may include: topography, slope and aspect, and altitude. The topography will affect the installation and layout of photovoltaic modules. For example, complex mountainous areas, hills, or areas with a large number of obstacles will increase the difficulty and cost of construction and may also affect the photovoltaic modules' ability to receive sunlight. The aspect will affect the angle of incidence of sunlight, and the slope will affect the installation method and difficulty of photovoltaic modules. Altitude will affect the intensity of solar radiation and the impact of clouds. While it is generally believed that higher solar radiation intensity is conducive to improving photovoltaic power generation efficiency, high altitudes may also result in strong winds, low temperatures, and other factors that are not conducive to the construction and operation of photovoltaic power generation systems.

[0064] Meteorological characteristic information for the construction site may include: solar radiation data (including annual / monthly / daily total solar radiation, the ratio of direct radiation to diffuse radiation, and the effective sunshine duration throughout the year), temperature data (including average temperature, extreme temperatures, and the temperature difference between day and night), wind speed and direction (including average wind speed, maximum wind speed, and wind direction distribution), precipitation and humidity (including annual precipitation, seasonal distribution of precipitation, and air humidity), cloud cover distribution, extreme weather events, and snow and ice accumulation. Solar radiation data directly affects power generation efficiency, PV panel type selection, and power generation potential; temperature data affects the structural durability of brackets and PV modules, as well as PV power generation efficiency; wind speed and direction affect the wind resistance requirements of brackets and PV modules; precipitation and humidity affect the cleanliness and corrosion of PV modules; cloud cover distribution affects the volatility of PV power generation; and extreme weather events and snow and ice accumulation directly affect the operational safety of PV power generation systems.

[0065] Step S102 generates photovoltaic construction targets based on terrain and meteorological information. These targets may include power generation, operation and maintenance costs, environmental benefits, and auxiliary power coordination indicators (including grid capacity, energy storage capacity, etc.). These targets are automatically generated using terrain and meteorological information and are tailored to the specific construction location. These targets are tailored to the specific location, enabling dynamic target generation and providing high design flexibility.

[0066] Step S103: Obtain photovoltaic construction constraints for the photovoltaic power generation system. These constraints include installation constraints, grid access constraints, and compliance constraints. Installation constraints limit the installation methods and specifications that the installation base (foundation, wall, roof) can withstand. Grid access constraints limit the grid's absorption capacity, the permissible degree of reverse absorption, and grid compliance with fluctuations. Compliance constraints are used to match various technical specifications and policy and regulatory requirements.

[0067] Step S104, select alternative electrical equipment and its parameters from the preset electrical equipment selection library based on the expected goals and constraints of photovoltaic construction. Electrical equipment may include: photovoltaic modules, cables, inverters, energy storage batteries, mounting brackets, etc. The electrical equipment selection library can collect information in advance on various types of equipment that meet the selection requirements and have been inspected. Each type of electrical equipment is configured with necessary parameters in the electrical equipment selection library. For example, photovoltaic modules may include: photovoltaic panel type (monocrystalline silicon, polycrystalline silicon, etc.), peak power, temperature coefficient, size, weight, installation method, etc.; inverters may include: maximum DC input voltage, MPPT voltage range, number of MPPT paths, rated AC power, power factor range, number of AC phases, operating temperature range, etc.

[0068] Alternative electrical equipment is selected from a preset electrical equipment selection library based on the expected goals and constraints of photovoltaic construction. It can quickly match the expected goals of photovoltaic construction and adapt to specific construction scenarios in a targeted manner, thereby improving the scientific nature of equipment selection and avoiding selection errors.

[0069] In some embodiments, step S104 of selecting alternative electrical equipment and its parameters from a preset electrical equipment selection library based on the expected goals of photovoltaic construction and photovoltaic construction constraints may include: generating electrical demand parameters based on the expected goals of photovoltaic construction and photovoltaic construction constraints; querying the electrical equipment selection library for electrical equipment that is compatible with the electrical demand parameters, thereby obtaining alternative electrical equipment and its parameters.

[0070] Step S105: Generate a device selection interface based on the parameters of the candidate electrical devices. The device selection interface can be generated based on the characteristics of the output device, such as a computer display, tablet screen, or smartphone screen, and the interface layout and human-computer interaction interface can be adjusted based on the interaction method.

[0071] Step S106 : determining electrical equipment of the photovoltaic power generation system in response to the operation acquired on the equipment selection interface.

[0072] The equipment selection interface is generated based on the parameters of the alternative electrical equipment, and responds to the obtained operations to determine the electrical equipment of the photovoltaic power generation system, using a friendly visual interactive method to assist designers in making quick decisions.

[0073] The method of the above embodiment solves the problems of poor adaptability and low efficiency existing in traditional photovoltaic electrical design, and provides basic conditions for the efficient, safe and stable operation of subsequent photovoltaic power generation systems.

[0074] Figure 2 The following is a flow chart of collecting terrain feature information in a method for designing electrical equipment for a photovoltaic power generation system according to an embodiment of the present invention. The steps of collecting terrain feature information at a location where the photovoltaic power generation system is to be constructed may include:

[0075] Step S201: obtaining a digital elevation model of the location to be constructed, wherein the digital elevation model is established using pre-collected terrain data.

[0076] Step S202: using a digital elevation model to identify the topography of the location to be constructed, and calculating the slope and direction.

[0077] Step S203: organizing the topography, landform, slope and aspect into terrain feature information in a preset data format.

[0078] A Digital Elevation Model (DEM) is a mathematical model that describes surface elevation in the form of a discrete numerical array. It expresses the topographical characteristics through a three-dimensional data structure consisting of plane coordinates (X, Y) and elevation values ​​(Z). By analyzing elevation model data, contour lines representing the topography can be extracted. For example, sparse contour lines indicate flat terrain, while dense contour lines indicate high terrain volume. The shape and spacing of the contour lines can be used to determine the type of landform. Using spatial analysis tools within geographic information system (GIS) software, slope and aspect can be calculated based on elevation model data. Slope values ​​can be expressed in degrees, while aspect can be expressed in degrees.

[0079] The elevation model can be obtained by requesting a professional surveying and mapping platform, or it can be obtained by modeling using data collected through satellite remote sensing, aerial surveying, ground surveying, etc.

[0080] The data format of topography, slope and aspect is required to have a unified coordinate system and elevation benchmark, and the unit and accuracy of each type of data are uniformly set according to construction requirements.

[0081] Figure 3 The figure is a flow chart of collecting meteorological characteristic information in a method for designing electrical equipment of a photovoltaic power generation system according to an embodiment of the present invention. The steps of collecting meteorological characteristic information of a location where the photovoltaic power generation system is to be constructed include:

[0082] Step S301: Collect historical meteorological data for the location to be constructed. This historical meteorological data can be obtained from historical measurements of meteorological monitoring equipment deployed at the location to be constructed, or from historical meteorological data published by meteorological authorities. This historical meteorological data may include daily, monthly, and annual temperature, humidity, wind speed, precipitation, solar radiation intensity, and extreme weather records.

[0083] Step S302: Calculate historical meteorological data using a pre-established climate model to obtain meteorological characteristic information.

[0084] Figure 4 The flowchart of generating the expected photovoltaic construction target in the design method of electrical equipment of a photovoltaic power generation system according to one embodiment of the present invention is shown in FIG. The steps of generating the expected photovoltaic construction target based on terrain feature information and meteorological feature information may include:

[0085] Step S401: Determine the area of ​​a photovoltaic installation area at a location to be constructed based on terrain feature information. The area of ​​the photovoltaic installation area is the area of ​​an area that meets the conditions for installing photovoltaic panels and is not blocked by sunlight.

[0086] Step S402: Evaluate the irradiation data of the photovoltaic installation area based on the meteorological characteristics information; the irradiation data of the photovoltaic installation area may include the daily average irradiation and the annual average irradiation. The daily average irradiation refers to the solar radiation energy received per unit area per day, usually expressed in MJ / m 2 The average daily radiation dose is expressed in megajoules per square meter per day. This value is affected by factors such as geographic location, season, weather conditions, and the surrounding environment. The annual average radiation dose can be calculated using the daily average radiation dose.

[0087] Step S403: Generate an expected photovoltaic construction target according to the area of ​​the photovoltaic installation area and the radiation data.

[0088] Figure 5 The following is a flow chart of obtaining photovoltaic construction constraints in a method for designing electrical equipment for a photovoltaic power generation system according to an embodiment of the present invention. The steps of obtaining photovoltaic construction constraints for a photovoltaic power generation system may include:

[0089] Step S501: Determine installation constraints within the photovoltaic construction constraints based on terrain feature information. Installation constraints can narrow down the range of possible installation options, such as the allowable bracket height, allowable bracket weight, allowable mounting method, allowable bracket tracking method, and so on.

[0090] Step S502: Obtain the grid environment at the proposed construction location and determine the grid access constraints within the photovoltaic construction constraints based on the grid environment. Grid operators will set requirements for photovoltaic installed capacity, power generation rates, and electrical safety based on factors such as distribution transformer capacity and line carrying capacity, power dispatch capabilities to mitigate photovoltaic power generation fluctuations, and the functionality of power metering equipment. Grid access constraints are used to standardize these requirements.

[0091] Step S503 obtains information about surrounding facilities at the proposed construction site and identifies compliance constraints within the PV construction constraints based on this information. Administrative approval authorities may impose restrictions on PV construction based on land use, ecological conditions, and transportation infrastructure. For example, they may prohibit PV installation along designated areas along transportation routes and require that PV construction comply with national land space planning and urban and rural planning requirements. These compliance constraints standardize the restrictions imposed by the aforementioned laws and administrative orders.

[0092] Figure 6 The present invention is a flowchart of generating and utilizing an equipment selection interface in a method for designing electrical equipment for a photovoltaic power generation system according to an embodiment of the present invention. Figure 7 Schematic diagram of a selection interface generated by a design method for electrical equipment of a photovoltaic power generation system according to an embodiment of the present invention. The step of generating the equipment selection interface based on the parameters of the candidate electrical equipment may include:

[0093] Step S601: Group the candidate electrical equipment according to the equipment type, and use each group of candidate electrical equipment as a form item in the dynamic form. The equipment type is grouped according to the function of the equipment. In addition to the name and model of the candidate electrical equipment, the form item of each group of equipment type can also include a brief description. For example, after the designer selects a certain alternative electrical equipment, the core parameters of the equipment and the corresponding description are displayed in the corresponding area of ​​the selection interface. For example, for the inverter, the information about the number of AC phases, maximum DC input voltage, MPPT voltage range, number of MPPT paths, rated AC power, etc. can be output. In each form item, the equipment that is most compatible with the expected goals of photovoltaic construction is prioritized at the front to increase the chance of being selected by the designer.

[0094] Step S602 establishes associations between different types of candidate electrical equipment and adjusts the order of the candidate elements in the form item based on these associations. Different types of candidate electrical equipment have interoperability relationships. For example, there are close associations between photovoltaic modules and inverters, and between photovoltaic modules and racks. This means that each photovoltaic module can be used with one or more compatible inverters and one or more compatible racks, resulting in optimal performance of the photovoltaic modules, inverters, and racks. Therefore, the dynamic form adjusts the order of the candidate elements (candidate electrical equipment) based on these associations in the background.

[0095] Step S603, sort the form items according to the preset sorting strategy to obtain the layout of the dynamic form. The sorting can be performed according to the function of the electrical equipment in the photovoltaic power generation system and the number of alternative electrical equipment in the group, for example, the core equipment of the photovoltaic power generation system is sorted higher, and the form items with a smaller number of alternative electrical equipment are sorted higher. In some embodiments, the photovoltaic power generation system puts the form items of core components such as photovoltaic modules, inverters, and energy storage at the front, and then further puts the form items with a smaller number of options in these core component form items at the front. In this way, on the one hand, the core functions of the photovoltaic power generation system can be matched more accurately; on the other hand, the form items with a smaller number of options can be preferred, and the selection range of subsequent form items can be narrowed through the association relationship, thereby improving the design efficiency.

[0096] Step S604: Generate a device selection interface corresponding to the dynamic form. After the above steps, the device selection interface is more convenient for designers to use, thereby improving interaction efficiency.

[0097] Step S605: Obtain a selection operation on the device selection interface. The selection operation can be configured according to the type of the device selection interface, such as providing an operation interface to the designer by selecting a multiple-selection box, a drop-down menu, a keyword prompt, etc.

[0098] In step S606, after a candidate electrical device is selected in one form item, the candidate elements and / or order in other form items are updated based on the associated relationships. For example, if a designer selects a photovoltaic module, the inverter and bracket form items will have the candidate elements compatible with the selected module ranked first. Alternatively, candidate elements that are incompatible with the selected module can be deleted. This dynamic form adjustment further improves design efficiency and accuracy.

[0099] Figure 7 The equipment selection interface is only for example. The order of photovoltaic modules, inverters, brackets and energy storage can be adjusted according to the above method. Figure 7Only some schematic diagrams of electrical equipment are provided. Those skilled in the art can configure the equipment selection interface according to the requirements of the photovoltaic power generation system and the method of the above embodiment.

[0100] The device selection interface can be configured in a personal computer, a smart phone, a tablet computer, or other dedicated electronic client devices, and outputted using the display screens of these devices.
