Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a solar photovoltaic power generation system based on tea-light complementarity. Background Art

[0002] By building photovoltaic power generation equipment in the tea garden, photovoltaic power generation can be achieved without occupying additional land resources, and shade can be provided for the tea trees, forming a sustainable tea-light complementary photovoltaic power generation system.

[0003] Among them, in the process of photovoltaic power generation system application, by monitoring the photovoltaic power generation equipment inside it, it is possible to determine the photovoltaic power generation equipment with abnormal power generation. However, after monitoring the photovoltaic power generation equipment with abnormal power generation, due to the many factors affecting the power generation, it is impossible to directly determine the photovoltaic power generation equipment corresponding to the abnormal power generation as the photovoltaic power generation equipment with operation risks. Therefore, how to predict and determine the photovoltaic power generation equipment with greater operation risks in the tea garden through abnormal power generation for easy control is a problem that needs to be solved at present;

[0004] Secondly, how to use the above-mentioned status analysis of photovoltaic power generation equipment in the tea garden to predict photovoltaic power generation equipment that will continue to have abnormal power generation in the subsequent period of time is also a problem that needs to be solved at present. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a solar photovoltaic power generation system based on tea-light complementarity, which can effectively solve the problem in the prior art that photovoltaic power generation equipment with higher operating risks cannot be predicted by abnormal power generation, and the problem that photovoltaic power generation equipment will continue to have abnormal power generation in the subsequent period of time.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a solar photovoltaic power generation system based on tea-light complementation, which at least includes: a power generation status monitoring module, which is used to obtain the average power generation of historical photovoltaic equipment in a specified area The actual power generation of current photovoltaic equipment , determine the actual power generation Whether it is an abnormal state, also includes:

[0008] The state loss analysis module is used to mark the photovoltaic equipment corresponding to the abnormal state as the target photovoltaic equipment, and perform state loss analysis on the target photovoltaic equipment to obtain the loss risk value. , based on the loss risk value Obtaining the risk level of the target photovoltaic device, and determining the display state of the target photovoltaic device in the plane coordinate system according to the risk level;

[0009] And, the power generation status supervision module is used to assign a supervisor to the primary linear path when the display status constitutes a primary linear path. When the assigning party is unable to deal with it in time, the module continuously monitors the designated area to obtain whether the display status constitutes a secondary linear path. When it is constituted, the module uses the primary linear path and the secondary linear path to determine the linear risk area that will exist in the designated area in the future, and thereby predict the overall actual power generation in the designated area.

[0010] Furthermore, the average power generation is obtained and actual power generation When the average power generation and actual power generation The weather is the same, and the average power generation is obtained at the specified time .

[0011] Furthermore, the average power generation is obtained The actual power generation needs to be obtained Use time of photovoltaic equipment To obtain and use time Average power generation of the same historical photovoltaic equipment .

[0012] Furthermore, the loss risk value The calculation formula is:

[0013]

[0014] In the formula, is the loss risk value, is the operating time of the photovoltaic equipment, is the degradation value of the output power of the photovoltaic device, is the mean temperature fluctuation of the photovoltaic device, is the mean value of the light intensity fluctuation of the photovoltaic device, is the maintenance frequency of photovoltaic equipment, The degree of foreign matter accumulation in photovoltaic equipment. for as well as The sum of the characteristics of and are the corresponding influence weights, is a constant.

[0015] Furthermore, the method for determining the risk level of the target photovoltaic equipment is as follows:

[0016] Get the risk interval, when When , the risk level of the photovoltaic equipment is low;

[0017] Get the risk interval, when When , the risk level of the photovoltaic equipment is medium;

[0018] Get the risk interval, when When , the risk level of photovoltaic equipment is high;

[0019] Therefore, according to The risk interval in which the target photovoltaic equipment is located is used to determine the risk level of the target photovoltaic equipment, and the average power generation of the corresponding photovoltaic equipment under the corresponding risk level of the target photovoltaic equipment is obtained. , and the average power generation in the clear state The actual power generation of the target photovoltaic equipment is required Corresponding to weather and usage time As a matching condition, determine the target photovoltaic device When determining the risk level, The corresponding photovoltaic equipment at the same risk level, thus the average power generation of the state The actual power generation Compare and generate judgment results, where:

[0020] when The actual power generation of the target PV equipment under the current risk level is is normal;

[0021] when When , the target photovoltaic equipment is in good power generation status;

[0022] when When , the power generation status of the target photovoltaic equipment is poor;

[0023] Furthermore, when When the target photovoltaic device is located in the specified area, the coordinate information is obtained, and the coordinate information of all photovoltaic devices in the specified area is input into the plane coordinate system by constructing a plane coordinate system to clarify the display status of the target photovoltaic device in the plane coordinate system, so as to perform risk control on the target photovoltaic device.

[0024] Furthermore, the method for determining the primary linear path is:

[0025] When the display state is a linear path, the corresponding coordinate information under the linear path is obtained, and a linear path is generated, and the point quantity of the coordinate information under this linear path is recorded.

[0026] Furthermore, when the primary linear path is clear, a supervisor is assigned to the primary linear path, and the target photovoltaic equipment under the primary linear path is controlled to be interrupted. When the interruption is not possible due to a shortage of maintenance resources, weather and environmental influences, or urgent needs of the power supply system, the following steps are performed:

[0027] Continuously monitor the designated area and continuously obtain the display status of the designated area to determine whether it is a linear path. If it is a linear path, mark it as a secondary linear path to determine whether it is the same as the primary linear path. When the primary linear path and the secondary linear path have the same coordinate information:

[0028] Obtain the same coordinate information on the primary linear path and the secondary linear path, and mark the same coordinate information as fixed coordinate points;

[0029] The fixed coordinate point is linearly extended under the specified area, specifically:

[0030] The fixed coordinate point remains unchanged, and the last coordinate information or the next coordinate information of the fixed coordinate point that changes on the primary linear path or the secondary linear path is used as the switching point to extend and construct a linear risk path, where:

[0031] When constructing a linear risk path, it is also necessary to determine whether the number of points in the coordinate information covered by the primary linear path and the secondary linear path is the same. If they are the same:

[0032] It is also necessary to construct a linear risk path using point quantities with coordinate information in a primary linear path or a secondary linear path, and to construct a linear risk path by extending in multiple directions using fixed coordinate points.

[0033] Furthermore, fixed coordinate points are reserved to avoid other coordinate information on the primary linear path or the secondary linear path to construct and generate multiple linear risk paths.

[0034] Furthermore, by marking the photovoltaic equipment with coordinate information under the linear risk path as the target photovoltaic equipment, if the primary linear path and the secondary linear path continue to exist during the continuous monitoring process:

[0035] Get whether the target PV equipment on the primary linear path and the secondary linear path has the same power generation XFD. If yes:

[0036] The linear risk path with the greatest impact is determined among multiple linear risk paths, and the linear risk path is combined with the primary linear path or the secondary linear path to predict the minimum overall actual power generation in the future in the specified area.

[0037] Furthermore, the method for determining the most affected linear risk path is:

[0038] Based on the same power generation XFD, the power generation FDL of the corresponding photovoltaic equipment as a whole on the linear risk path is obtained;

[0039] Obtaining the overall power generation LSD when the photovoltaic equipment on the linear risk path is not determined as the target photovoltaic equipment;

[0040] Obtain the linear risk path with the largest difference between LSD and FDL, and mark it as the most affected linear risk path. Combine the future FDL of this linear risk path with the XFD of the primary and secondary linear paths to obtain the overall power generation ZTD of the target PV equipment after the specified area is affected.

[0041] Avoid the most affected linear risk path, primary linear path and secondary linear path in the specified area to determine the remaining photovoltaic equipment under continuous monitoring time. , thereby determining the overall actual power generation in the specified area at subsequent times.

[0042] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0043] The target photovoltaic equipment is pre-judged through the actual power generation of the photovoltaic equipment, so as to perform state loss analysis on the target photovoltaic equipment, thereby determining the risk level of the target photovoltaic equipment, and determining whether to perform risk control according to the risk level of the target photovoltaic equipment, thereby forming a timely emergency response;

[0044] Based on the display area formed by the risk level, a primary linear path, a secondary linear path and a linear risk area are delineated in the specified area to determine the target photovoltaic equipment in the area, so as to form a forecast of the lowest overall actual power generation in the future area, so that the photovoltaic management and control integration center can make advance decisions and plans on the power consumption of the use area in a timely manner.

[0047] Figure 2 It is a schematic diagram of the method for determining the actual power generation of the present invention. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The present invention will be further described below in conjunction with the embodiments.

[0050] Example 1 (see Figure 1-Figure 2 ): A solar photovoltaic power generation system based on tea-light complementation, including at least:

[0051] The power generation status monitoring module is used to obtain the average power generation of photovoltaic equipment under different (multiple same) weather conditions in history , and obtain the actual power generation of photovoltaic equipment under the current weather conditions , the actual power generation Average power generation Compare to determine the actual power generation Whether it is an abnormal state;

[0052] In the above, it should be noted that it refers to the average power generation of photovoltaic equipment under the same historical weather conditions at a specified time. The specified time can be monthly, quarterly, etc., so as to calculate the power generation of photovoltaic equipment on the same day under the same weather conditions in history. , and calculate the average power generation based on the number of same weather conditions (The power generation of photovoltaic equipment on the same day under the same weather conditions The ratio between the sum of the same weather conditions) and the average power generation Construct an average power generation database DA (the average power generation constructed by different weather conditions) ), and then, by obtaining the actual power generation under the current weather , this can be input into the current weather average power generation database DA to determine the average power generation under the corresponding weather. Therefore, when the actual power generation Less than average power generation When the actual power generation of the photovoltaic system is The photovoltaic device is abnormal, so that the status can be adjusted later.

[0053] Among them, the actual power generation under the current weather conditions is determined in the average power generation database DA The corresponding average power generation The actual power generation needs to be obtained The use time of its photovoltaic equipment To obtain and use time Average power generation of photovoltaic equipment under different weather conditions in the same history Therefore, by limiting the use time , can determine the usage time of the same input The losses caused by this can be used to more accurately determine the losses that do not meet the average power generation. Actual power generation .

[0054] Also includes:

[0055] State loss analysis module, which is used to pre-identify the non-average power generation Actual power generation Extract and convert the actual power generation The corresponding photovoltaic device is marked as the target photovoltaic device, and thus, the state loss analysis is performed on the target photovoltaic device, wherein the calculation formula of the state loss analysis is as follows:

[0056]

[0057] In the formula, is the loss risk value, is the operating time of the photovoltaic equipment, is the degradation value of the output power of the photovoltaic device (the difference between the initial power and the current power of the photovoltaic device is determined in advance, and the ratio between the difference and the initial power is the degradation value), is the average temperature fluctuation of the photovoltaic equipment (the ratio of the sum of the difference between the maximum temperature and the minimum temperature of each day under multiple days to multiple days, where the multiple days are weekly or monthly, and the sharp fluctuation of temperature may increase the loss risk of photovoltaic equipment, that is, increase the risk of abnormal loss), is the average light intensity fluctuation of the photovoltaic equipment (the sum of the difference between the highest light intensity and the lowest light intensity of each day under multiple days and the ratio between multiple days. The sharp fluctuation of light intensity may increase the loss risk of photovoltaic equipment, thereby increasing the demand for maintenance. For example, frequent cloud cover may cause rapid changes in the temperature of photovoltaic panels, which may accelerate the aging of materials). is the maintenance frequency of the PV equipment (the ratio between the number of historical maintenance times and the operating time), is the degree of foreign matter accumulation on the photovoltaic equipment (determined by the product of the sum of the areas where most foreign matter accumulates and the sum of the types of accumulated foreign matter. The types of foreign matter include sand, gravel, leaves, bird droppings, etc. It should be noted that the area of ​​foreign matter accumulation on the photovoltaic equipment is calculated by collecting image data from monitoring equipment). for as well as The sum of the characteristics of and are the corresponding influence weights, is a constant.

[0058] Based on the above, the execution risk assessment is as follows:

[0059] Get the risk interval, when When , the risk level of the photovoltaic equipment is low;

[0060] Get the risk interval, when When , the risk level of the photovoltaic equipment is medium;

[0061] Get the risk interval, when When , the risk level of photovoltaic equipment is high;

[0062] Therefore, according to The risk interval in which the target photovoltaic equipment is located is used to determine the risk level of the target photovoltaic equipment, and the average power generation of the corresponding photovoltaic equipment under the corresponding risk level of the target photovoltaic equipment is obtained. , and the average power generation in the clear state The actual power generation of the target photovoltaic equipment is required Corresponding to weather and usage time The matching condition is determined so that the average power generation is determined. It can reflect the average power generation level of the photovoltaic equipment in this situation, and then determine the target photovoltaic equipment based on the above When the risk level is The corresponding photovoltaic equipment with the same risk level will have the average power generation of the state The actual power generation Compare and generate judgment results (it should be noted that the actual power generation Combined with the safety margin, the safety margin is used to consider uncertain factors, such as the actual power generation caused by normal power generation losses. When small fluctuations occur, the actual power generation during this process It is normal, as usually set to the actual power generation in this field , the specific limit is not given, so the actual power generation after considering the safety margin can be Execute comparison and judgment), where:

[0063] when When the target photovoltaic equipment is at the current risk level, the actual power generation It is normal, that is, no control is required. When the power generation needs to be increased, it can be based on The impact characteristics can be improved by performing corresponding improvements on the target photovoltaic equipment;

[0064] when When the target photovoltaic equipment generates Exceeds the average power generation of the previously assessed state , then it can reflect that the power generation performance of the target photovoltaic equipment is in good condition;

[0065] when When the target photovoltaic equipment generates Less than the average power generation of the originally assessed state , then it can be reflected that the power generation performance of the target photovoltaic equipment is poor;

[0066] Therefore, in order to determine the actual power generation of the target photovoltaic device Analysis of the affected situations:

[0067] when , then the coordinate information of the target photovoltaic device is obtained in the designated area (because this solution is applied to the photovoltaic power generation system of tea-light complementation, the designated area is the tea garden where the target photovoltaic device is currently located). It should be noted that for the photovoltaic device built in the designated area, multiple solar photovoltaic panels will be set up, and each photovoltaic device will form a photovoltaic device in combination with the power transmission part. Therefore, there will be multiple photovoltaic devices, and then, the target photovoltaic device is determined by the above-mentioned power generation status monitoring module and the status loss analysis module, thereby determining the The target photovoltaic equipment and its corresponding coordinate information are obtained by constructing a plane coordinate system, and the coordinate information of all photovoltaic equipment in the specified area is input into the plane coordinate system to clarify the display state of the current target photovoltaic equipment in the plane coordinate system. Therefore, in order to perform risk control on the target photovoltaic equipment, this solution also includes:

[0068] The power generation status monitoring module is used to obtain the display status of the coordinate information of multiple target photovoltaic devices in the plane coordinate system, where:

[0069] When the display status is a linear path (line), the corresponding coordinate information under the linear path is obtained, and a linear path is generated. At the same time, the point quantity of the coordinate information under this linear path is recorded. Among them, when the linear path is clear, the supervisor can be assigned to the linear path according to the principle of shortest distance (the supervisor is used to repair the photovoltaic equipment faults, and is assigned through the photovoltaic control integration center), and the target photovoltaic equipment under the linear path is controlled to interrupt power generation to ensure safe operation. However, it should be noted that when it is impossible to interrupt maintenance due to shortage of maintenance resources, adverse weather conditions or emergency of the power supply system, the following steps need to be performed:

[0070] Continuously monitor the designated area (the continuous monitoring method can be statistically performed once a day or at intervals of a certain number of hours, etc., which is not limited here), and continuously obtain the display status of the current designated area to determine whether it is a linear path. If it continues to be a linear path, it will be marked as a secondary linear path to determine whether it is the same as the primary linear path, where:

[0071] When the primary linear path and the secondary linear path have the same coordinate information, obtain the same coordinate information on the primary linear path and the secondary linear path, mark the same coordinate information as a fixed coordinate point, and linearly extend the fixed coordinate point under the specified area. Specifically, the fixed coordinate point remains unchanged, and the last coordinate information or the next coordinate information of the fixed coordinate point that changes on the primary linear path or the secondary linear path is used as a switching point to extend and construct a linear risk path. When constructing the linear risk path, it is also determined whether the number of points of the coordinate information covered in the primary linear path and the secondary linear path is the same. If they are the same:

[0072] It is also necessary to construct a linear risk path with the point quantity of coordinate information in the primary linear path or the secondary linear path. At the same time, because the primary linear path or the secondary linear path only has the same fixed coordinate points and the others are different, the linear risk path is constructed based on the fixed coordinate points in multiple directions mentioned above, and the fixed coordinate points are retained to avoid the construction of other coordinate information on the primary linear path or the secondary linear path. This will generate multiple linear risk paths. The corresponding photovoltaic equipment under this multi-path linear risk path has a greater operating risk in the subsequent time.

[0073] Therefore, the photovoltaic equipment with coordinate information under the linear risk path is marked as the target photovoltaic equipment. If the primary linear path and the secondary linear path continue to exist during the continuous monitoring process, obtain whether the target photovoltaic equipment on the primary linear path and the secondary linear path has the same power generation XFD (it means that the sum of the power generation XFD of all target photovoltaic equipment on both the primary linear path and the secondary linear path is the same). If so:

[0074] Determine the most affected linear risk path among multiple linear risk paths, and combine the linear risk path with the primary linear path or the secondary linear path to predict the lowest overall actual power generation in the future in the specified area, where:

[0075] The method for determining the most (largest) affected linear risk path is:

[0076] Based on the same power generation XFD, the power generation FDL of the corresponding photovoltaic equipment as a whole on the linear risk path is obtained;

[0077] Obtain the overall power generation LSD (the total power generation of multiple photovoltaic devices) when the photovoltaic device on the linear risk path is not determined as the target photovoltaic device (no linear risk path is formed) sum);

[0078] Obtain the linear risk path with the largest difference between LSD and FDL, and mark it as the most affected linear risk path. Combine (add) the FDL formed by this linear risk path in the future with the XFD of the primary linear path and the secondary linear path to obtain the overall power generation ZTD of the target PV equipment after the specified area is affected;

[0079] Avoid the most affected linear risk path, primary linear path and secondary linear path in the specified area to determine the remaining PV equipment under the continuous monitoring time (such as on the same day or at a certain interval) in the specified area. , thereby determining the overall actual power generation in the specified area at a later time (the remaining photovoltaic equipment and ZTD);

[0080] This will form a forecast of the future minimum overall actual power generation in the specified area. Based on the power consumption of the use area (such as residential or industrial areas), it will be easy to judge whether the overall actual power generation has an impact on the power supply to the use area, so that the photovoltaic management and control integration center (referring to the online management and control platform for photovoltaic equipment in a specified area) can make advance decisions and plans for the power consumption of the use area.

[0081] It is worth noting that according to the display status and display conditions of the primary linear path, the secondary linear path and the linear risk path, when only one other linear risk path is added to the original primary linear path, the secondary linear path and the linear risk path under continuous monitoring each time, the above-mentioned prediction of the overall actual power generation is used to deduce the lowest overall actual power generation of the designated area under each subsequent continuous monitoring, so that the photovoltaic management and control integration center can form advance decisions and plans.

[0082] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
