[0029] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0030] As mentioned in the background technology, in the related technology, the design method for the inclination and orientation of photovoltaic modules is usually based on static environmental parameters, such as local latitude, annual average solar radiation, etc., which are simplified and approximated, resulting in low power generation returns of photovoltaic projects. In addition, the dynamic changes of parameters such as solar radiation intensity and ambient temperature in different time periods will also make it difficult for the design results to achieve the best economic benefits.

[0031] In view of this, the embodiments of the present disclosure provide a method, device, storage medium and electronic device for determining the installation angle of a photovoltaic module, which can effectively determine the optimal installation angle of the photovoltaic module, thereby improving the power generation and economic benefits of the photovoltaic system.

[0032] Figure 1 is a flow chart of a method for determining a photovoltaic assembly installation angle according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the method may include the following steps: Step S101, obtaining a plurality of installation angle combinations of photovoltaic modules, wherein each installation angle combination includes an azimuth angle and an inclination angle.

[0033] Step S102, determining a target installation angle combination according to the installation angle combination, a preset optimization function and a preset genetic algorithm, wherein the preset optimization function is a function that sums the product of the power generation in each target period and the time-of-use electricity price corresponding to the target period.

[0034] Among them, the time periods for time-of-use electricity prices include valley period, low period, parity period, peak period and peak period.

[0035] It should be understood that existing photovoltaic projects are generally designed to face south for maximum power generation. In order to maximize the economic benefits of photovoltaic power generation, distributed photovoltaic arrays need to deviate from a certain direction to achieve the best azimuth, while minimizing the energy loss. Therefore, to maximize the economic benefits of photovoltaic power generation, it is necessary to find the best azimuth and best inclination of photovoltaic modules.

[0036] It should also be understood that with the continuous development of smart grids and the power market, the time-of-use electricity price mechanism has become an important part of the power market. The time-of-use electricity price mechanism sets different electricity prices in different time periods to guide users to reasonably adjust their electricity demand and achieve optimal allocation of power resources. For distributed photovoltaic systems, incorporating the time-of-use electricity price mechanism into the design considerations can further optimize the inclination and orientation of photovoltaic modules, so that they can generate electricity efficiently in different time periods and increase the power generation revenue of photovoltaic power stations.

[0037] For example, the preset optimization function can be expressed as follows: (1) Among them, maxP t Indicates the maximum photovoltaic benefit in one day, Q n Indicates the power generation at a certain hour, K n Indicates the time-of-use electricity price for a certain hour, and n can represent the number of hours from 6 to 18.

[0038] For example, regarding Q nIt can be expressed by the following relationship (2): (2) in, Indicates the azimuth angle of the photovoltaic module, represents the inclination angle of the photovoltaic module, and f(*) represents the constraint equation of power generation. And, The range can be set to , The range can be set to .

[0039] For example, regarding K n The specific type of can be shown in the following relation (3): (3) Among them, K 深谷 Indicates the time-of-use electricity price during the valley period in the region (may not be set in some regions), K 低谷 represents the low time-of-use electricity price in the area, K 平价 represents the time-of-use electricity price in the region, K 高峰 represents the peak time-of-use electricity price in the region, K 尖峰 Indicates the peak time-of-use electricity price in the area.

[0040] Step S103, determining the installation angle of the photovoltaic module according to the target installation angle combination.

[0041] Through the above method, multiple installation angle combinations of photovoltaic modules are obtained, and the target installation angle combination is determined according to the installation angle combination, the preset optimization function and the preset genetic algorithm, and the installation angle of the photovoltaic module is determined according to the target installation angle combination. Among them, the installation angle combination of photovoltaic modules is determined by using the preset genetic algorithm and the preset optimization function, and taking into account the impact of the time-of-use electricity price mechanism on the power generation income of the photovoltaic system, the optimal photovoltaic module installation angle can be effectively determined, thereby improving the power generation and economic benefits of the photovoltaic system.

[0042] In a possible implementation, determining a target installation angle combination according to the installation angle combination, a preset optimization function, and a preset genetic algorithm may include: Obtaining chromosomes in a preset genetic algorithm corresponding to each installation angle combination; Determine the initial population based on chromosomes; According to the preset optimization function, determine the fitness value corresponding to each chromosome in the initial population; When the preset termination condition is met, the maximum value of the fitness value corresponding to each chromosome is determined as the target fitness value, and the target installation angle combination is determined according to the chromosome corresponding to the target fitness value.

[0043] It should be understood that the actual installation angle value is converted into a chromosome code that can be processed by the genetic algorithm, usually using binary encoding. Each angle can be converted into a binary string of fixed length. When encoding, it is necessary to consider the range and accuracy requirements of the angle value and reasonably set the number of binary bits.

[0044] For example, the preset termination condition may be set to when the maximum number of iterations is reached or the fitness value is no longer significantly improved.

[0045] For example, the size and number of the initial population can be set according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0046] In a possible implementation, the method may further include: When the preset termination condition is not met, a selection operation is performed according to the fitness value, and the target chromosomes within the preset fitness threshold range are retained; According to the target chromosome, a new population is generated through a crossover operation and a mutation operation, wherein the crossover operation includes exchanging some genes of the chromosome according to a preset crossover probability, and the mutation operation includes randomly changing the genes in the chromosome according to a preset mutation probability; The new population is determined as the initial population for a new round of iterations, and the step of determining the fitness value corresponding to each chromosome in the initial population according to the preset optimization function is returned to be executed until the preset termination condition is met.

[0047] It should be understood that the optimization problem of the inclination and azimuth of photovoltaic modules in distributed photovoltaic systems is actually a multi-variable, multi-constrained nonlinear optimization problem. The complexity of this problem is mainly reflected in the following aspects: 1) Multivariability: The variables that need to be considered during the optimization process include not only the inclination and azimuth of the photovoltaic modules, but may also involve multiple dimensions such as time-of-use electricity prices and photovoltaic irradiance.

[0048] 2) Nonlinear relationship: There is a complex nonlinear relationship between the power generation efficiency of the photovoltaic system and the solar radiation intensity, ambient temperature, component inclination and azimuth, which is difficult to accurately describe with a simple mathematical formula.

[0049] 3) Multiple constraints: In actual design, the installation of photovoltaic systems must meet multiple constraints such as building structural safety, lighting conditions, and roof utilization.

[0050] 4) Impact of time-of-use electricity prices: The introduction of the time-of-use electricity price mechanism has further complicated the problem, because the power generation income in different time periods is different, and it is necessary to comprehensively consider economic benefits and power generation efficiency.

[0051] Therefore, given the complexity of the above problems, traditional optimization methods often find it difficult to obtain the global optimal solution. As a random search algorithm that simulates the biological evolution process, genetic algorithms are suitable for solving such multi-polar nonlinear optimization problems, and have the following advantages: 1) Strong versatility: Genetic algorithms do not rely on specific domain knowledge of the problem and only need to use fitness functions to evaluate the quality of the solution. Therefore, they can be widely used in various optimization problems.

[0052] 2) Good robustness: Genetic algorithms search through group evolution, which can effectively avoid falling into local optimal solutions and improve the globality of the solution.

[0053] 3) Good parallelism: The genetic algorithm operates on a set of solutions, namely the population, which can be evaluated and evolved simultaneously, making it easy to implement parallel computing and improve solution efficiency.

[0054] 4) Adaptability: Operations such as crossover and mutation in genetic algorithms are random and can adaptively adjust the search direction and step size to increase the diversity of solutions.

[0055] For example, applying genetic algorithms to the optimization of the inclination and azimuth of distributed photovoltaic modules can design Figure 2 Steps shown: Step S201 : encoding the inclination angle and azimuth angle of the photovoltaic module into chromosomes in a genetic algorithm.

[0056] It should be understood that the inclination and azimuth of the photovoltaic module can be encoded as chromosomes in the genetic algorithm, and each chromosome corresponds to a set of specific inclination and azimuth, that is, each chromosome represents a possible solution.

[0057] Step S202, randomly generate a certain number of chromosomes as an initial population.

[0058] Step S203, calculating the fitness value of each chromosome.

[0059] For example, the fitness value of each chromosome can be calculated and its advantages and disadvantages can be evaluated based on factors such as the power generation of the photovoltaic system, the time-of-use electricity price mechanism, and the operating cost.

[0060] Step S204, determine whether the stop criterion is met, if so, execute step S205, otherwise execute step S206.

[0061] Step S205, output the result.

[0062] It should be understood that outputting the optimal chromosome in the final population can determine the optimal inclination and azimuth of the photovoltaic module.

[0063] Step S206, selecting some chromosomes to enter the next generation population according to the fitness value.

[0064] It should be understood that selecting some excellent chromosomes to enter the next generation population based on fitness values ​​can ensure the inheritance of excellent genes and improve accuracy.

[0065] Step S207, performing crossover and mutation operations on the chromosomes in the next generation population, and returning to step S203.

[0066] It should be understood that by exchanging some genes of two chromosomes through the crossover operation, a new chromosome can be generated; by randomly modifying some genes in the chromosome through the mutation operation, the diversity of the population can be increased. The fitness evaluation, selection, crossover and mutation operations can be repeated until the stopping criteria are met.

[0067] Through the above method, the effective operation of the genetic algorithm can be ensured and better optimization results can be obtained.

[0068] In a possible implementation, determining the fitness value corresponding to each chromosome in the initial population according to a preset optimization function may include: Input the installation angle combination represented by each chromosome in the initial population into a preset photovoltaic simulation model to determine the target power generation data corresponding to each installation angle combination; The maximum benefit value is calculated according to the target power generation data and the preset optimization function, and the maximum benefit value is determined as the fitness value corresponding to each chromosome in the initial population.

[0069] Through the above method, the performance of different installation angle combinations can be accurately evaluated, providing a reliable fitness evaluation basis for the genetic algorithm.

[0070] For example, PVsyst software can be used for the preset photovoltaic simulation model. PVsyst is a software used to design and simulate photovoltaic systems. It can be used to evaluate the performance and economy of photovoltaic systems. Users can use PVsyst to design photovoltaic systems, including selecting photovoltaic modules, inverters, batteries and other equipment, and setting the layout and parameters of the system.

[0071] Specifically, a typical day can be selected in each month, the azimuth angle range is set to -90°~90°, the inclination angle range is set to 0°~90°, and there are 181×91=16471 combinations of inclination angle and azimuth angle. The Python programming software provides a function for calculating the number of combinations, and the combination is generated through Python's itertools.combinations, while math.comb can directly calculate the number of combinations.

[0072] Specifically, we can first calculate the lengths of the two intervals, and then multiply the two lengths to get the number of possible combinations of number pairs. That is, there are a total of 16,471 different combinations of any number in the integer range from -90 to 90 (including -90 and 90) and any number in the integer range from 0 to 90 (including 0 and 90).

[0073] For example, Figure 3 is a schematic diagram of the distribution of time-of-use electricity prices in Shandong Province according to an exemplary embodiment of the present disclosure. Figure 3 As shown, the time-of-use electricity prices in Shandong Province from January to February and December can be specifically as follows: 6:00 to 9:00 and 15:00 are flat-section electricity prices, 10:00 and 14:00 are low-valley electricity prices, 11:00 to 13:00 is deep-valley electricity prices, and 16:00 to 18:00 is peak electricity prices; the time-of-use electricity prices from March to May can be specifically as follows: 6:00 to 9:00, 15:00 and 16:00 are flat-section electricity prices, 10:00 and 14:00 are low-valley electricity prices, and 11:00 to 13:00 is deep-valley electricity prices. The peak electricity price is from 17:00 to 18:00; the specific time-of-use electricity price from June to August can be: 6:00 to 15:00 is the flat electricity price, 16:00 is the peak electricity price, and 17:00 to 18:00 is the peak electricity price; the specific time-of-use electricity price from September to November can be: 6:00 to 9:00 and 15:00 is the flat electricity price, 10:00 and 14:00 is the low-valley electricity price, 11:00 to 13:00 is the deep-valley electricity price, 16:00 is the peak electricity price, and 17:00 to 18:00 is the peak electricity price. It can be seen that the peak and peak of the electricity price are distributed in the afternoon, so the azimuth can be considered to be set in the west direction, and the power generation will be higher in the afternoon.

[0074] For example, in actual applications, the photovoltaic simulation model can be preset, that is, the combination of different azimuth angles and inclination angles can be simulated by PVsyst software to complete the project setting and obtain the radiation situation. The specific parameter page diagram can be shown as follows: Figures 4 to 9 As shown. Among them, Figure 4 This is a schematic diagram of the parameter page when the photovoltaic module inclination angle is 30° and the azimuth angle is 0°; Figure 5 This is a schematic diagram of the parameter page when the photovoltaic module has an inclination angle of 30° and an azimuth angle of 25°; Figure 6 This is a schematic diagram of the parameter page when the photovoltaic module has an inclination angle of 30° and an azimuth angle of 45°; Figure 7 This is a schematic diagram of the parameter page when the photovoltaic module has an inclination angle of 30° and an azimuth angle of 75°; Figure 8 This is a schematic diagram of the parameter page when the photovoltaic module has an inclination angle of 30° and an azimuth angle of 90°; Fig. 9 It is a page diagram of simulation configuration parameters.

[0075] For example, a typical day can be selected according to actual conditions, and the inclination angle of the photovoltaic module can be selected to be 30° toward the south, and different azimuth angles can be selected: 0°, 25° south-west, 45° southwest, 75° west-southwest, 90° due west, etc. The embodiments of the present disclosure are not limited to this.

[0076] For example, when the photovoltaic module has a tilt angle of 30°, the hourly power generation in different time periods is derived according to different azimuth angles and radiation conditions, and the corresponding electricity prices and electricity revenues in each time period can be shown in Tables 1 and 2 below.

[0077] Table 1

[0078] Among them, it can be obtained from Table 1 that when the inclination angle of the photovoltaic module is fixed at 30° and the azimuth angles are 0°, 25° and 45° respectively, the hourly power generation, electricity price and electricity fee income corresponding to the time period.

[0079] Table 2

[0080] Among them, it can be obtained from Table 2 that when the inclination angle of the photovoltaic module is fixed at 30° and the azimuth angles are 75° and 90° respectively, the hourly power generation, electricity price and electricity fee income corresponding to the time period.

[0081] Fig.10 The figure is a graph showing the relationship between power generation and time at different azimuth angles when the inclination angle of a photovoltaic module is 30° according to an exemplary embodiment of the present disclosure.

[0082] By combining Table 1 and Fig.10 It can be seen from the content that the total power generation will decrease when the azimuth is biased to the west, but the total investment return is the largest at the azimuth of 25°. Therefore, the 25° azimuth can be selected as the benchmark to consider narrowing the azimuth range, and the hourly power generation corresponding to the time periods of multiple angle combinations can be derived through simulation again to find the maximum return value. At the same time, the conditions of different seasons and different inclinations should also be considered. Finally, the optimal inclination and azimuth of the photovoltaic module can be obtained to maximize the economic benefits and power generation efficiency of the photovoltaic system.

[0083] In a possible implementation, obtaining multiple installation angle combinations of photovoltaic components may include: According to the preset inclination angle range and the preset azimuth angle range of the photovoltaic module, a plurality of installation angle combinations of the photovoltaic module are obtained.

[0084] It should be understood that by presetting the inclination angle range and the azimuth angle range, multiple installation angle combinations can be generated, and these combinations will be used as candidate solutions for the input of the genetic algorithm, thereby improving the optimization efficiency and meeting engineering requirements.

[0085] It should also be understood that the solution in this embodiment comprehensively considers multiple factors such as the time-of-use electricity price mechanism, solar radiation intensity, ambient temperature, etc., and can maximize the economic benefits and power generation efficiency of the photovoltaic system by accurately calculating the optimal inclination and orientation of the photovoltaic components. It can also provide new ideas and methods for the optimal design of distributed photovoltaic systems and promote the further development of the photovoltaic industry.
