Technical Field
[0001] The present invention relates to the technical field of power generation project construction assessment, and in particular to a method for assessing the construction of a photovoltaic power generation project based on the power supply side of a shared energy storage power station. Background Art
[0002] As photovoltaic power generation technology continues to mature and its costs fall, the combination of shared energy storage power stations and photovoltaic power generation projects will become an important trend in the development of new energy. In order to promote the application of photovoltaic power generation projects in shared energy storage power stations and improve the efficiency and reliability of energy storage systems, it is necessary to evaluate and consider the construction of photovoltaic power generation projects, and achieve efficient storage and release of electrical energy by utilizing solar energy resources, smooth out power generation fluctuations, and ultimately improve power generation efficiency.
[0003] For example, the invention patent with announcement number CN117114315B announces a high-efficiency power generation installation method for solar photovoltaic power stations, which belongs to the field of photovoltaic power generation technology. It includes the following steps: site selection evaluation: regional condition evaluation according to the address required for photovoltaic power station construction; installed capacity calculation: using genetic algorithm to obtain the optimal solution for installed capacity; constructing steel structure composition: according to the obtained optimal installed capacity, calculate the actual photovoltaic panel area and use RTK to obtain high-precision positioning; calculate the optimal inclination angle: calculate the optimal inclination angle according to the obtained high-precision positioning information; construction: construction according to the obtained steel structure composition and optimal inclination angle; monitoring and optimization: modify the weight coefficient of the fitness function based on actual monitoring data. Through the three aspects of site selection evaluation, capacity planning and optimal inclination angle calculation, the utilization of resources and the return on investment are optimized to the greatest extent, thereby achieving high-efficiency construction and power generation of photovoltaic power stations.
[0004] For example, the invention patent with announcement number CN106021934B announces a method for evaluating regional available solar energy resources. It includes collecting basic data of the area to be evaluated; quantitatively calculating the amount of solar energy radiation available in the area every day; and quantitatively calculating the optimal photovoltaic configuration in the area. The provided method for evaluating regional available solar energy resources calculates the amount of solar energy radiation available in the area every day based on regional geographic meteorological information such as longitude and latitude, sunshine intensity, etc. Then, based on the amount of solar energy radiation available every day, the land use conditions for photovoltaic construction in the area are considered, and the optimal photovoltaic installed capacity is determined with economy as the goal. The application of this calculation and evaluation method and analysis and evaluation system can ensure that the photovoltaic installed in the region can fully utilize the solar energy radiation in the region every day to generate electricity to the maximum extent, and avoid the waste of investment caused by the idleness of photovoltaic capacity due to inability to generate electricity after excessive construction. At the same time, it can provide planning suggestions for the construction of regional power grids and power sources.
[0005] Combined with the above technical solutions, it is found that in the current process of evaluating photovoltaic power generation construction, only a single-dimensional quantitative analysis of the construction area will result in a large data analysis error between the final estimated photovoltaic power generation and the actual photovoltaic power generation. As a result, the estimated power generation cannot meet the power supply demand, making it impossible to achieve efficient storage of photovoltaic power generation, ultimately affecting the power generation efficiency. Summary of the invention
[0006] In view of the deficiencies in the prior art, the present invention provides a method for evaluating the construction of a photovoltaic power generation project on the power supply side of a shared energy storage power station, which can effectively solve the problems involved in the above-mentioned background technology.
[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for evaluating the construction of a photovoltaic power generation project on the power supply side of a shared energy storage power station, comprising: S1. Synchronously collecting power resource information of the area to which the photovoltaic power generation project belongs and environmental resource utilization information of the area to which the photovoltaic power generation project belongs, so as to integrate and evaluate the power storage index required by the photovoltaic power generation project, and match the estimated design parameter set of the photovoltaic power generation project; S2. Through the estimated design parameter set of the photovoltaic power generation project, predict the simulated construction process to which the estimated design parameter set of the photovoltaic power generation project belongs, and at the same time predict the construction environment of the area to which the photovoltaic power generation project belongs, and comprehensively evaluate the simulated construction benefit index of the photovoltaic power generation project; S3. Compare the simulated construction benefit index of the photovoltaic power generation project with the preset simulated construction benefit threshold, and finally issue an early warning prompt for the construction of the photovoltaic power generation project on the power supply side of the shared energy storage power station.
[0008] As a further method, the estimated design parameter set of the photovoltaic power generation project is matched, and the specific matching process is:
[0009] The power demand and energy storage index of the photovoltaic power generation project are matched with the estimated design parameter sets corresponding to the power demand and energy storage index intervals preset in the photovoltaic power generation construction library to match the estimated design parameter set of the photovoltaic power generation project.
[0010] As a further method, the estimated design parameter set of the photovoltaic power generation project specifically includes the purchase quantity of each type of photovoltaic components, the installation angle of each type of photovoltaic components, the installation spacing of each type of photovoltaic components, the purchase quantity of each electrical equipment, and the purchase quantity of each auxiliary equipment.
[0011] As a further method, the simulated construction benefit index of the photovoltaic power generation project is evaluated by comprehensively processing the estimated construction information of the photovoltaic power generation project and the environmental pollution information of the area to which the photovoltaic power generation project belongs, thereby evaluating the simulated construction benefit index of the photovoltaic power generation project.
[0012] As a further method, the above-mentioned early warning prompt is given to the construction of the photovoltaic power generation project on the power supply side of the shared energy storage power station. The specific early warning prompt process is:
[0013] The simulated construction benefit index of the photovoltaic power generation project is compared with the preset simulated construction benefit threshold. If the simulated construction benefit index of the photovoltaic power generation project is lower than the preset simulated construction benefit threshold, an early warning will be issued for the construction of the photovoltaic power generation project on the power supply side of the shared energy storage power station. If the simulated construction benefit index of the photovoltaic power generation project is higher than or equal to the preset simulated construction benefit threshold, there is no need to issue an early warning for the construction of the photovoltaic power generation project on the power supply side of the shared energy storage power station.

[0019] Figure 1 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION
[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] Reference Figure 1 As shown, the present invention provides a method for evaluating the construction of a photovoltaic power generation project on the power supply side of a shared energy storage power station, including: S1. Synchronously collecting power resource information of the area to which the photovoltaic power generation project belongs and environmental resource utilization information of the area to which the photovoltaic power generation project belongs, so as to integrate and evaluate the power storage index required for the photovoltaic power generation project, and match the estimated design parameter set of the photovoltaic power generation project.
[0022] Specifically, the estimated design parameter set of the photovoltaic power generation project is matched, and the specific matching process is:
[0023] The power storage index required by the photovoltaic power generation project is matched with the estimated design parameter set corresponding to each power storage index interval preset in the photovoltaic power generation construction library to match the estimated design parameter set of the photovoltaic power generation project. The specific matching process is as follows:
[0024] Each required power storage index interval corresponds to an estimated design parameter set. The required power storage index interval to which the required power storage index of the photovoltaic power generation project belongs is queried in the photovoltaic power generation construction database. The estimated design parameter set corresponding to the required power storage index interval is the estimated design parameter set of the photovoltaic power generation project. It should be noted that the estimated design parameter set corresponding to each required power storage index interval is formulated by photovoltaic power generation construction specialists based on the experience of historical power generation construction projects with numerical values and corresponding rules.
[0025] Furthermore, the power resource information of the region to which the photovoltaic power generation project belongs specifically includes the average daily growth rate of power load in the region to which the photovoltaic power generation project belongs and the total power consumption of the region to which the photovoltaic power generation project belongs on each resource utilization day.
[0026] It should be explained that the average daily growth rate of the electricity load in the area where the above-mentioned photovoltaic power generation project is located can be calculated by querying the previous daily electricity load data of the area through the resource utilization cloud platform. For example, the electricity load of the day and the electricity load of yesterday are obtained, and the electricity load of the day is subtracted from the electricity load of yesterday. The value obtained is divided by the electricity load of yesterday, which is the electricity load growth rate of the day; the total electricity consumption of the area to which the photovoltaic power generation project belongs on each resource utilization day can be obtained by querying the daily electricity load of the area during this query process through the resource utilization cloud platform, so as to obtain the total electricity consumption on each resource utilization day. The resource utilization cloud platform is a system that stores various resource utilization information in the area to which the photovoltaic power generation project belongs, and its information includes but is not limited to the power resource information and environmental resource utilization information in this example; wherein, each resource utilization day is obtained by dividing the duration of the current acquisition of the value by days, indicating multiple days for data acquisition and analysis before the construction of the photovoltaic power generation project; in this example, the area to which the photovoltaic power generation project belongs refers to the industrial park, that is, the concentration of industrial production, which has a large electricity demand and needs to be powered by a combination of photovoltaic power generation and power supply-side energy storage to ensure stable electricity consumption in the industrial park.
[0027] Specifically, the environmental resource utilization information of the area to which the photovoltaic power generation project belongs includes the annual average sunshine hours in the area to which the photovoltaic power generation project belongs, the annual average solar radiation in the area to which the photovoltaic power generation project belongs, and the annual average population growth density in the area to which the photovoltaic power generation project belongs.
[0028] It should be explained that the above average annual sunshine hours and average annual solar radiation can be obtained by querying the total number of sunshine hours and total solar radiation in the region in a year through the resource utilization cloud platform, and dividing them by the total number of days in a year, and finally obtaining the average annual sunshine hours and average annual solar radiation. For example, in a year, i.e. 365 days in this region, the total number of sunshine hours is 100 hours, then the average annual sunshine hours is equal to The annual average population growth density of the region where the photovoltaic power generation project is located can be calculated by obtaining the population growth in the region within one year through Internet data and dividing it by the geographical area of the region.
[0029] Furthermore, the power storage index required by the photovoltaic power generation project is specifically expressed as follows:

[0032]
[0033] In the formula, is the power storage index required for photovoltaic power generation projects. In this example, if we want to build a photovoltaic power generation area with low cost and high power generation efficiency, we need to accurately evaluate the power consumption in the photovoltaic power generation project area, that is, we need to consider the use of its power resources. If the average daily growth rate of the power load in the area is large, it means that the power load in the area fluctuates greatly, reflecting that the total power consumption in the area on multiple utilization days is relatively deviated from the average value, which will cause the area to need more electricity to support its operation, thus greatly affecting the power storage index required for this expression. At the same time, if we want to improve the utilization rate of photovoltaic power generation, we need to analyze the environmental factors affecting photovoltaic power generation in the area, that is, if the number of sunshine hours and solar radiation are small, it means that the availability of photovoltaic power generation in the area is not high, and more photovoltaic modules are needed to support its power consumption. If the population growth density in the area is large, it means that the power consumption in the area is large, which further explains the increase in the power storage index required for this expression. In summary, multi-dimensional data considerations are needed to obtain a more accurate regional power situation and accurately improve the rational application of subsequent photovoltaic modules.

[0049] S2. Through the estimated design parameter set of the photovoltaic power generation project, the simulated construction process to which the estimated design parameter set of the photovoltaic power generation project belongs is predicted, and at the same time, the construction environment of the area to which the photovoltaic power generation project belongs is predicted, and the simulated construction benefit indicators of the photovoltaic power generation project are comprehensively evaluated.
[0050] In a specific embodiment, the present invention synchronously collects power resource information and environmental resource utilization information of the area to which the photovoltaic power generation project belongs, thereby integrating and evaluating the power storage indicators required by the photovoltaic power generation project, and matching the estimated design parameter set of the photovoltaic power generation project. It can accurately consider the construction information corresponding to the photovoltaic power generation project to meet the electricity demand, and by combining with the energy storage power station, it can smooth the power generation fluctuations and ultimately improve the power generation efficiency.
[0051] Specifically, the simulated construction benefit index of the photovoltaic power generation project is evaluated by performing comprehensive data processing on the estimated construction information of the photovoltaic power generation project and the environmental pollution information of the area to which the photovoltaic power generation project belongs, thereby evaluating the simulated construction benefit index of the photovoltaic power generation project. The evaluation expression is as follows:
[0052]
[0053] in,
[0054]
[0055] In the formula, is the simulated construction benefit indicator of photovoltaic power generation projects. In this example, when simulating the construction of photovoltaic power generation projects, it is necessary to consider the influencing factors in the construction process and whether the electricity demand of the area can be met after construction. Therefore, through comprehensive analysis of its construction information, that is, whether the estimated construction time is within a reasonable numerical range, the estimated impact of construction power consumption, and whether the estimated power generation is lower than the minimum power generation demand, the impact degree of construction association can be obtained; at the same time, there will be certain environmental pollution after construction. If its total carbon emissions and total wastewater emissions are higher than the standards that can handle pollution, the simulated construction of the photovoltaic power generation project needs to be further adjusted in order to meet the power supply demand and environmental treatment needs, and ultimately improve the accuracy of subsequent comprehensive power release and power storage with energy storage power stations.
[0056] The weight factors corresponding to the estimated construction benefit values preset for the photovoltaic power generation construction library are a mapping set of estimated construction benefit values and their corresponding weight factors constructed based on the relationship between historical estimated construction benefit values and simulated construction benefit indicators, and the real-time estimated construction benefit values are input into the mapping set to obtain the weight factors corresponding to the estimated construction benefit values.

[0059] It is the environmental pollution impact value of the area where the photovoltaic power generation project is located. It is a numerical value of the environmental pollution impact status obtained through comprehensive analysis of the predicted total carbon emissions and the predicted total wastewater emissions.
[0060] The estimated construction duration of a photovoltaic power generation project refers to the duration required to construct this photovoltaic power generation project based on the estimated design parameter set.
[0061] The construction reference duration preset for the photovoltaic power generation construction library indicates the total time period most suitable for the construction of a photovoltaic power generation project.
[0062] The estimated construction power consumption of a photovoltaic power generation project refers to the power consumption required during the construction process of this photovoltaic power generation project based on the estimated design parameter set.
[0063] The influencing factors of the unit values of the estimated construction power consumption preset for the photovoltaic power generation construction library are constructed by constructing a mapping set of the estimated construction power consumption and its corresponding influencing factors based on the relationship between the historical estimated construction power consumption and the estimated construction benefit value, and the real-time estimated construction power consumption is input into the mapping set to obtain the influencing factors of the unit values of the estimated construction power consumption.

[0071] Furthermore, the estimated design parameter set of the photovoltaic power generation project specifically includes the purchase quantity of each type of photovoltaic components, the installation angle of each type of photovoltaic components, the installation spacing of each type of photovoltaic components, the purchase quantity of each electrical equipment, and the purchase quantity of each auxiliary equipment.
[0072] In this example, the estimated design parameter set of the photovoltaic power generation project, the design parameters therein are closely related to the parameters corresponding to the power storage index of the photovoltaic power generation project. For example, in an example embodiment, if the average daily growth rate of power load is 1%, the average annual power consumption is 10 million kWh, and the average annual sunshine hours are 1200 hours, then the area requires 1%*10 million kWh*1200 hours=1.2 million kWh of power generation. If the type of photovoltaic module is only one type of monocrystalline silicon photovoltaic module, and the power of a single photovoltaic module is 300 watts, and the power generation efficiency is 15%, then the power generation of a single photovoltaic module is 45 watts. According to the required power generation of 1.2 million kWh, the number of photovoltaic modules to be equipped is approximately 2667, which is the purchase quantity of this type of monocrystalline silicon photovoltaic modules.
[0073] It should be noted that the installation angle and installation spacing of the above-mentioned photovoltaic modules are related to the geographical location, climatic conditions and other influencing factors of the construction area. Therefore, it is necessary to comprehensively consider the geographical location, climatic conditions and other influencing factors of the photovoltaic power generation project area to determine the optimal installation angle and installation spacing.
[0074] It needs to be explained that the above-mentioned photovoltaic module types include but are not limited to monocrystalline silicon photovoltaic modules and polycrystalline silicon photovoltaic modules; electrical equipment types include but are not limited to photovoltaic inverters, combiner boxes, distribution cabinets, and transformers; auxiliary equipment types include but are not limited to photovoltaic brackets, photovoltaic tracking systems, photovoltaic cleaning equipment, and photovoltaic maintenance equipment; their quantities are all related to the required power generation of the photovoltaic power generation project, environmental factors, etc.
[0075] Furthermore, the simulated construction process of the estimated design parameter set of the photovoltaic power generation project is predicted to predict the estimated construction information of the photovoltaic power generation project, specifically including the estimated construction time of the photovoltaic power generation project, the estimated construction power consumption of the photovoltaic power generation project and the estimated power generation of the photovoltaic power generation project.
[0076] It should be noted that the estimated design parameter set of the above-mentioned photovoltaic power generation project belongs to the simulated construction process, which specifically refers to the process of installing photovoltaic modules, corresponding electrical equipment and auxiliary equipment.
[0077] In this example, the above-mentioned estimated construction time is the construction time obtained by querying the installation time of a single photovoltaic module, a single electrical equipment and a single auxiliary equipment through the equipment management cloud platform; the estimated construction power consumption is obtained by querying the power consumption of certain equipment or construction steps in the construction process and summing them up. For example, in the trial operation step, the power consumption of electrical equipment such as photovoltaic inverters, junction boxes, and distribution cabinets can be queried through the equipment management cloud platform to operate; the project estimated power generation is obtained by querying the power generation of a single photovoltaic module through the equipment management cloud platform and summing them up; the equipment management cloud platform is a system that stores various specification parameters of various equipment (such as photovoltaic modules, electrical equipment, and auxiliary equipment in this example).
[0078] Specifically, the construction environment of the area where the photovoltaic power generation project is located is predicted to obtain environmental pollution information of the area where the photovoltaic power generation project is located, including the predicted total carbon emissions in the area where the photovoltaic power generation project is located and the predicted total wastewater emissions in the area where the photovoltaic power generation project is located.
[0079] In this example, the predicted total carbon emissions can be queried through the equipment management cloud platform to obtain the total carbon emissions generated by the equipment operation during the trial operation of the project; the predicted total wastewater emissions can be queried through the management cloud platform to obtain the total amount of wastewater containing harmful substances generated during the cutting and processing of photovoltaic modules.
[0080] In a specific embodiment, the present invention accurately predicts the simulated construction process of the photovoltaic power generation project and the construction environment of the area to which the photovoltaic power generation project belongs, comprehensively evaluates the simulated construction benefit indicators of the photovoltaic power generation project, and compares them with the preset simulated construction benefit threshold. It can provide accurate data evaluation basis for early warning prompts for the construction of photovoltaic power generation projects on the power supply side of the subsequent shared energy storage power station, and ultimately improve the energy storage efficiency and release efficiency of the power station.
[0081] S3. Compare the simulated construction benefit index of the photovoltaic power generation project with the preset simulated construction benefit threshold, and finally issue an early warning for the construction of the photovoltaic power generation project on the power supply side of the shared energy storage power station.
[0082] Specifically, the early warning reminder for the construction of the photovoltaic power generation project on the power supply side of the shared energy storage power station is as follows:
[0083] The simulated construction benefit index of the photovoltaic power generation project is compared with the preset simulated construction benefit threshold, which represents the minimum value of the simulated construction benefit index within a reasonable range. The previous simulated construction benefit indexes in the photovoltaic power generation construction library can be queried and averaged to obtain the index.
[0084] If the simulated construction benefit index of the photovoltaic power generation project is lower than the preset simulated construction benefit threshold, it means that the simulated construction benefit of the photovoltaic power generation project is not good and has not reached the expected benefit level; it is necessary to issue an early warning for the construction of the photovoltaic power generation project on the power supply side of the shared energy storage power station. The specific early warning process is as follows:
[0085] The project construction early warning mechanism in the project construction management system sends out early warning prompts (in the form of red alarm lights, expedited documents, etc.) that indicate the need for adjustment of project construction to the management and control interface of the project construction management and control personnel through the wireless network, so that the project construction management and control personnel can receive the early warning that the project construction needs to be adjusted in a timely manner, and then make further adjustments to the project construction.
[0086] If the simulated construction benefit index of a photovoltaic power generation project is higher than or equal to the preset simulated construction benefit threshold, it means that the simulated construction benefit of the photovoltaic power generation project is good and can achieve the expected benefit level.
