By analyzing the component parameters of the current PV power station and the interaction parameters of the equipment to be updated, it achieves accurate acquisition of the interaction parameters of external interactive devices and precise calculation of the interaction parameters of the updated equipment. Furthermore, based on the interaction parameters of the updated equipment, it selects target PV equipment and uses the target PV equipment to manage the replacement of aging PV equipment, enabling timely replacement of aging PV equipment. Considering the operational relationships between various PV devices, it ensures the coordination and compatibility between the new equipment and other equipment, improves the overall operating efficiency of the power system, and saves energy.

[0010] In one optional implementation, the component parameter analysis module includes:

[0011] The first judgment unit is used to compare the key operating parameters in the component parameters with the first preset parameter range. If at least one key operating parameter is greater than the first preset parameter range, the current device corresponding to the component parameters is taken as the device to be updated.

[0012] The second judgment unit is used to compare the regular operating parameters in the component parameters with the second preset parameter range. If at least two regular operating parameters are greater than the preset parameter range, the current device corresponding to the component parameters is taken as the device to be updated.

[0013] This embodiment provides a management device for old photovoltaic equipment. By comparing key operating parameters in the component parameters with a first preset parameter range, or comparing regular operating parameters with a second preset parameter range, it achieves accurate identification of equipment to be replaced, laying the foundation for timely replacement of old photovoltaic equipment.

[0014] In one optional implementation, the interactive parameter update module includes:

[0015] The acquisition unit is used to determine the external interactive device based on the interaction parameters of the device to be updated, and to acquire the interaction parameters of the external interactive device.

[0016] The analysis unit is used to analyze the interaction parameters of external interactive devices to obtain the value range of the interaction parameters of the device to be updated.

[0017] The update unit is used to determine the updated interaction parameters of the device to be updated based on the value range corresponding to the interaction parameters of the device to be updated.

[0024] This embodiment provides a management device for old photovoltaic equipment. By analyzing and judging the quantity and attributes of the interaction parameters of external interactive devices, it realizes the accurate calculation of the value range of the interaction parameters of the device to be updated, so that the interaction parameters of the updated photovoltaic equipment are within a reasonable value range, ensuring the coordination and compatibility between the updated photovoltaic equipment and other devices.

[0025] In one alternative implementation, the management module includes:

[0026] The determination unit is used to determine the component parameters of the device to be updated by using a lookup table method based on the value range of the interaction parameters of the updated device to be updated.

[0027] The selection unit is used to select the target photovoltaic equipment based on the component parameters of the equipment to be updated, and to replace the old photovoltaic equipment with the target photovoltaic equipment.

[0028] This embodiment provides a management device for old photovoltaic equipment. Based on the value range of the interaction parameters of the equipment to be updated, the device uses a lookup table method to obtain the component parameters of the equipment to be updated, thereby achieving fast and accurate acquisition of component parameters and enabling the selected target photovoltaic equipment to operate normally in the power system.

[0029] In one optional implementation, the selection unit is further configured to obtain the operating requirements of the target photovoltaic device, obtain the value range of the component parameters of the device to be updated based on the operating requirements of the target photovoltaic device, and select the target photovoltaic device based on the value range of the component parameters of the device to be updated.

[0030] This embodiment provides a management device for old photovoltaic equipment. By obtaining the value range of the component parameters of the equipment to be updated based on the operating requirements of the target photovoltaic equipment, the component parameters of the updated equipment are more in line with the operating requirements of the equipment, thus ensuring the normal operation of the target photovoltaic equipment in the power system.

[0041] Figure 3 This is a schematic diagram of the hardware structure of a computer device according to an embodiment of the present invention. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] For the renovation projects of old photovoltaic power station equipment, the greater the decline in the power generation of the power station, the higher the electricity price of the power station; the more problems the power station has, the greater the actual benefits of renovation, and the higher the value of such power station renovation.

[0044] After frequent use and wear, old equipment in photovoltaic power plants may malfunction or experience performance degradation. Furthermore, old equipment may have problems such as improper installation and aging electrical wiring, posing safety hazards such as electric shock, short circuits, and fires. In addition, old equipment may have lower efficiency, leading to energy waste and increased operating costs, and its compatibility and coordination with other new or existing equipment may deteriorate.

[0045] This embodiment provides a management device for legacy photovoltaic equipment. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0046] This embodiment provides a management device for old photovoltaic equipment, such as... Figure 1 As shown, it includes:

[0047] The component parameter analysis module 101 is used to obtain the component parameters of the current photovoltaic power station, analyze the component parameters, and determine the equipment to be updated.

[0048] Specifically, the component parameters of the current photovoltaic power station are the internal operating parameters of the photovoltaic equipment. Among them, the component parameters include the operating parameters of the photovoltaic equipment that do not interact with other equipment; some parameters change with the changes of the interaction parameters, and some parameters change with the working status and duration of the photovoltaic equipment, so as to ensure the operating efficiency and output of the current photovoltaic equipment, and also to display and characterize the current status of the photovoltaic equipment, and ensure a certain working efficiency.

[0049] The interaction parameter update module 102 is used to obtain the interaction parameters of the device to be updated, determine the external interaction device based on the interaction parameters of the device to be updated, obtain the interaction parameters of the external interaction device, update the interaction parameters of the device to be updated based on the interaction parameters of the external interaction device, and obtain the updated interaction parameters of the device to be updated.

[0050] Specifically, interaction parameters are parameters used to interact with or be adjusted by external photovoltaic equipment. They mainly participate in the overall or partial system operation to ensure the safe and efficient operation of the photovoltaic power station.

[0051] The management module 103 is used to select target photovoltaic equipment based on the interactive parameters of the updated equipment to be updated, and to manage the replacement of old photovoltaic equipment using the target photovoltaic equipment.

[0052] This embodiment provides a management device for aging photovoltaic (PV) equipment. By analyzing the component parameters of the current PV power station and the interaction parameters of the equipment to be updated, it achieves accurate acquisition of the interaction parameters of external interactive devices and precise calculation of the interaction parameters of the updated equipment. Furthermore, based on the interaction parameters of the updated equipment, it selects target PV equipment and uses the target PV equipment to manage the replacement of aging PV equipment, enabling timely replacement of aging PV equipment. Considering the operational relationships between various PV devices, it ensures the coordination and compatibility between the new equipment and other equipment, improves the overall operating efficiency of the power system, and saves energy.

[0053] In some optional implementations, the component parameter analysis module 101 includes:

[0054] The first judgment unit 1011 is used to compare the key operating parameters in the component parameters with the first preset parameter range. If at least one key operating parameter is greater than the first preset parameter range, the current device corresponding to the component parameters is taken as the device to be updated.

[0055] Specifically, key operating parameters are the main indicators of normal or efficient operation of energy storage equipment. Key operating parameters may include rated power, SOC (State of Charge), etc.

[0056] For example, if the component parameters are selected as rated power or equipment energy storage, and the rated power is less than 60% of the original rated power, or the equipment energy storage (efficiency) is less than 70% of the specified value, these situations have a significant impact on the normal operation of the current photovoltaic equipment or the overall system. Therefore, the photovoltaic equipment corresponding to these component parameters is considered as the equipment to be replaced.

[0057] The second judgment unit 1012 is used to compare the regular operating parameters in the component parameters with the second preset parameter range. If at least two regular operating parameters are greater than the preset parameter range, the current device corresponding to the component parameters is taken as the device to be updated.

[0058] Specifically, routine operating parameters are those that are typically monitored during the operation of energy storage devices, such as temperature and voltage. The importance of routine operating parameters is lower than that of critical operating parameters.

[0059] For example, if two or more of the normal operating parameters of voltage, temperature, or other equipment are below 70% or above 20%, it is considered that the change in the normal operating parameters exceeds the range specified for efficient or safe operation, which will affect the operation of the overall power system. Therefore, the current equipment corresponding to the component parameters is regarded as the equipment to be updated.

[0060] This embodiment provides a management device for old photovoltaic equipment. By comparing key operating parameters in the component parameters with a first preset parameter range, or comparing regular operating parameters with a second preset parameter range, it achieves accurate identification of equipment to be replaced, laying the foundation for timely replacement of old photovoltaic equipment.

[0061] In some optional implementations, the interaction parameter update module 102 includes:

[0062] The acquisition unit 1021 is used to determine the external interactive device based on the interaction parameters of the device to be updated, and to acquire the interaction parameters of the external interactive device.

[0063] Specifically, the external devices corresponding to each interaction parameter of the device to be updated are analyzed. That is, there may be one or more external devices. Based on the interaction parameters of each external device, the range of the same interaction parameter corresponding to the parameters of one or more external devices is analyzed to obtain the reasonable value range of the interaction parameters required by the updated device (new device). That is, the interaction parameter of a device to be updated may correspond to the parameter of one external device or may correspond to the parameter of multiple external devices at the same time.

[0064] The analysis unit 1022 is used to analyze the interaction parameters of the external interactive device to obtain the value range of the interaction parameters of the device to be updated.

[0065] The update unit 1023 is used to determine the updated interaction parameters of the device to be updated based on the value range corresponding to the interaction parameters of the device to be updated.

[0066] This embodiment provides a management device for old photovoltaic equipment. By analyzing the interaction parameters of external interactive devices, the value range of the interaction parameters of the device to be updated is obtained. This fully considers the operating relationship between various photovoltaic devices, ensures the coordination and compatibility between the updated photovoltaic equipment and other devices, and improves the overall operating efficiency of the power system.

[0067] In some optional implementations, the analysis unit 1022 includes:

[0068] The first judgment subunit 10221 is used to obtain the value range of the interaction parameters of the device to be updated if the number of interaction parameters of the external interaction device is one and the attributes of the interaction parameters of the external interaction devices are the same.

[0069] Specifically, the same attributes refer to the interaction parameters of external interactive devices that represent the same index, such as SOC, voltage, etc.

[0070] For example, if the interaction parameter 'a' of the new device (i.e. the device to be updated) corresponds only to the interaction parameter 'a' of the external interactive device A, then the value range of the interaction parameter 'a' is 1-5, and the value range of the interaction parameter 'a' of the device to be updated is 1-5.

[0071] The second judgment subunit 10222 is used to calculate the value range of the interaction parameters of the device to be updated based on the interaction parameters of the external interactive device and using a preset conversion coefficient if the number of interaction parameters of the external interactive device is one and the attributes of the interaction parameters of the external interactive device are different.

[0072] For example, if the interaction parameter of the new device is 'a', and it only corresponds to the interaction parameter b of the external interactive device A, then the value range of the interaction parameter b is 1-5. Therefore, the reasonable value range of the interaction parameter a of the new device is k(1-5), where k() represents the conversion formula or coefficient for calculating the interaction parameter b to the interaction parameter a; where the same letter represents the same attribute.

[0073] The third judgment subunit 10223 is used to obtain the first cross range of the at least two interaction parameters if the interaction parameters of the external interaction device have at least two interaction parameters and the attributes of the at least two interaction parameters are the same, and to use the first cross range as the value range corresponding to the interaction parameters of the device to be updated.

[0074] For example, if the interaction parameter of the new device is 'a', and the corresponding interaction parameters of external interactive device A and external interactive device B are also 'a', then the value range of the interaction parameter 'a' of external interactive device A is 1-5, and the value range of the interaction parameter 'a' of external interactive device B is 3-7. Therefore, the value range of the interaction parameter of the device to be updated is 3-5.

[0075] The fourth judgment subunit 10224 is used to determine the first value range and the second value range based on the at least two interaction parameters and the attributes of the at least two interaction parameters are different, and to obtain the second intersection range of the first value range and the second value range, and to use the second intersection range as the value range corresponding to the interaction parameter of the device to be updated if the interaction parameter of the external interaction device has at least two interaction parameters and the attributes of the at least two interaction parameters are different.

[0076] For example, given the interaction parameter 'a' for a new device, and corresponding interaction parameters 'a' and 'b' for external device A, and 'a' and 'c' for external device B, the value range for interaction parameter 'a' of external device A is 1-5, the value range for interaction parameter 'a' of external device B is 2-7, the value range for interaction parameter 'b' of external device A is 0-1, and the value range for interaction parameter 'c' of external device B is 3-10. Therefore, for interaction parameter 'b', the value range for interaction parameter 'a' is 0-3 using a preset conversion coefficient k (0-1); for interaction parameter 'c', the value range for interaction parameter 'a' is 1-6 using a preset conversion coefficient m (3-10); and for interaction parameter 'a', a reasonable value range is 2-5. Combining these three value ranges, a reasonable value range for interaction parameter 'a' is 2-3, meaning the value range corresponding to the interaction parameter of the device to be updated is 2-3.

[0077] This embodiment provides a management device for old photovoltaic equipment. By analyzing and judging the quantity and attributes of the interaction parameters of external interactive devices, it realizes the accurate calculation of the value range of the interaction parameters of the device to be updated, so that the interaction parameters of the updated photovoltaic equipment are within a reasonable value range, ensuring the coordination and compatibility between the updated photovoltaic equipment and other devices.

[0078] In some alternative implementations, the management module 103 includes:

[0079] The determining unit 1031 is used to determine the component parameters of the device to be updated by using a lookup table method based on the value range of the interaction parameters of the updated device.

[0080] Specifically, based on the value range of the interaction parameters of the device to be updated, the parameters of each component of the new device (i.e., the device to be updated) are obtained. That is, the value of each component parameter is obtained through relevant standards or table lookup, and the value range of the component parameters is determined according to the preset operating requirements of the new device.

[0081] Furthermore, the standardized information and query tables are usually the specifications or historical parameter value ranges that meet the requirements for efficient and safe operation of photovoltaic equipment.

[0082] For example, for photovoltaic energy storage device X, the ranges of interaction parameters a, b, and c are (1-3), (0-1), and (5-10), respectively; for interaction parameter a, the ranges of the corresponding component parameters v and n are (2-6), (3-9), and (4-12), respectively, based on standardized information and table lookup; for interaction parameter b, the ranges of the corresponding component parameters o and p are (0-2), (1-4), and (5-8), respectively, based on standardized information and table lookup; for interaction parameter c, the ranges of the corresponding component parameters q and r are (3-5), (5-10), and (10-20), respectively, based on standardized information and table lookup.

[0083] The selection unit 1032 is used to select the target photovoltaic equipment based on the component parameters of the equipment to be updated, and replace the old photovoltaic equipment with the target photovoltaic equipment.

[0084] Specifically, the component parameters of the aforementioned equipment to be updated are used as recommended parameters for selecting the target photovoltaic equipment, and then the equipment to be updated (i.e., the old photovoltaic equipment) is replaced with the target photovoltaic equipment.

[0085] This embodiment provides a management device for old photovoltaic equipment. Based on the value range of the interaction parameters of the equipment to be updated, the device uses a lookup table method to obtain the component parameters of the equipment to be updated, thereby achieving fast and accurate acquisition of component parameters and enabling the selected target photovoltaic equipment to operate normally in the power system.

[0086] In some optional embodiments, the selection unit 1032 is further configured to obtain the operating requirements of the target photovoltaic equipment, obtain the value range of the component parameters of the device to be updated based on the operating requirements of the target photovoltaic equipment, and select the target photovoltaic equipment based on the value range of the component parameters of the device to be updated.

[0087] Specifically, based on the standardization or safety management needs of photovoltaic equipment in a photovoltaic power plant, and using multiple interaction parameters of the new equipment (i.e., the equipment to be updated), the component parameters of each new equipment are obtained by looking up a table, and the current operating requirements of the new equipment are obtained, thus determining the reasonable range of values ​​for each component parameter required by the updated equipment (new equipment).

[0088] Furthermore, the operating requirements of the target photovoltaic equipment are usually the fluctuation range of the photovoltaic equipment operating parameters, such as the range of the current value (-10%, +10%), or the range of the standard value (90%-100%).

[0089] This embodiment provides a management device for old photovoltaic equipment. By obtaining the value range of the component parameters of the equipment to be updated based on the operating requirements of the target photovoltaic equipment, the component parameters of the updated equipment are more in line with the operating requirements of the equipment, thus ensuring the normal operation of the target photovoltaic equipment in the power system.

It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0094] Step S203: The management module selects the target photovoltaic equipment based on the interaction parameters of the updated equipment to be updated, and uses the target photovoltaic equipment to manage the replacement of old photovoltaic equipment.
