[0042] 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] For renovation projects of old photovoltaic power station equipment, the greater the power generation attenuation of the power station, the higher the electricity price of the power station; the more problems the power station has, the greater the benefits of the renovation are actually, and the value of the renovation of such power stations is also higher.

[0044] After frequent use and wear, old equipment in photovoltaic power stations may malfunction or experience performance degradation. In addition, old equipment may have problems such as improper installation and aging electrical circuits, posing safety hazards such as electric shock, short circuit and fire. In addition, the efficiency of old equipment may be low, resulting in energy waste and increased operating costs, and the coordination and compatibility with other new equipment or normal equipment will deteriorate.

[0045] In this embodiment, a management device for old photovoltaic equipment is provided. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

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

[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 which the component parameters include the operating parameters of the photovoltaic equipment that have no interaction with other equipment; some parameters change with the change of the interaction parameters, and some parameters change with the working status and duration of the photovoltaic equipment, ensuring the operating efficiency and output of the current photovoltaic equipment, and can also display and characterize the status of the current photovoltaic equipment to ensure a certain working efficiency.

[0049] The interaction parameter updating 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, the interaction parameters are used to interact with external photovoltaic devices or are adjusted under the influence of external photovoltaic devices. They mainly participate in the overall or local system work to ensure the safe operation and efficiency of the photovoltaic power station.

[0051] The management module 103 is used to select a target photovoltaic device based on the updated interaction parameters of the device to be updated, and use the target photovoltaic device to perform replacement management on the old photovoltaic device.

[0052] The present embodiment provides a management device for old photovoltaic equipment, which achieves accurate acquisition of interaction parameters of external interactive equipment and precise calculation of interaction parameters of updated equipment to be updated by analyzing component parameters of the current photovoltaic power station and interaction parameters of equipment to be updated. Furthermore, target photovoltaic equipment is selected based on the interaction parameters of the equipment to be updated after the update, and replacement management of old photovoltaic equipment is performed using the target photovoltaic equipment, thereby achieving timely replacement of old photovoltaic equipment. Furthermore, the operating relationship between each photovoltaic equipment is taken into consideration, thereby ensuring coordination and compatibility between new equipment and other equipment, thereby improving the overall operating efficiency of the power system and saving 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, and if at least one key operating parameter is greater than the first preset parameter range, the current device corresponding to the component parameters is used as the device to be updated.

[0055] Specifically, key operating parameters are main indicators of normal or efficient operation of energy storage equipment, and 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 device power storage capacity, and the rated power is lower than 60% of the original rated power, or the device power storage capacity (efficiency) is lower than the prescribed 70%, these situations will have a significant impact on the normal operation of the current photovoltaic equipment or the overall system. Therefore, the photovoltaic equipment corresponding to the component parameters will be treated as the equipment to be updated.

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

[0058] Specifically, conventional operating parameters are parameters that are usually detected when the energy storage device is running, such as temperature, voltage, etc. The importance of conventional operating parameters is lower than that of key operating parameters.

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

[0060] The present embodiment provides a management device for old photovoltaic equipment, which achieves accurate identification of equipment to be updated by comparing key operating parameters in component parameters with a first preset parameter range, or comparing conventional operating parameters with a second preset parameter range, thereby laying a foundation for timely replacement of old photovoltaic equipment.

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

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

[0063] Specifically, the external devices corresponding to each interaction parameter of the device to be updated are analyzed, that is, there are one or more external devices. According to the interaction parameter 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 corresponding to the interaction parameter required by the updated device (new device), that is, an interaction parameter of a device to be updated may correspond to the parameter of one external device, or may correspond to the parameters of multiple external devices at the same time.

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

[0065] The updating unit 1023 is configured 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] The present embodiment provides a management device for old photovoltaic equipment, which analyzes the interaction parameters of external interactive devices to obtain the value range corresponding to the interaction parameters of the equipment to be updated, fully considers the operating relationship between each photovoltaic device, ensures the coordination and compatibility between the updated photovoltaic equipment and other equipment, and improves the overall operating efficiency of the power system.

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

[0068] The first judging subunit 10221 is configured to obtain a value range corresponding to the interaction parameter of the device to be updated if the number corresponding to the interaction parameter 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 attribute is that the interaction parameters of the external interaction device represent the same indicator, such as SOC, voltage, etc.

[0070] For example, if the interaction parameter of the new device (ie the device to be updated) is a, and it only corresponds to the interaction parameter a of the external interaction device A, then the value range of the interaction parameter a is 1-5, and the corresponding 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 corresponding to the interaction parameter of the device to be updated based on the interaction parameter of the external interaction device using a preset conversion coefficient if the number corresponding to the interaction parameter of the external interaction device is one and the attributes of the interaction parameters of the external interaction 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 interaction device A, the value range of the interaction parameter b is 1-5, and 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; the same letter represents the same attribute.

[0073] The third judgment subunit 10223 is used to obtain a first intersection range of at least two interaction parameters if the interaction parameters of the external interaction device have at least two interaction parameters and the attributes of at least two interaction parameters are the same, and use the first intersection 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 parameter a of the external interaction device A and the interaction parameter a of the external interaction device B are obtained, the value range of the interaction parameter a of the external interaction device A is 1-5, and the value range of the interaction parameter a of the external interaction device B is 3-7. Therefore, the corresponding 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 using a preset conversion coefficient if the interaction parameters of the external interaction device have at least two interaction parameters and the attributes of at least two interaction parameters are different, and obtain the second intersection range of the first value range and the second value range, and use the second intersection range as the value range corresponding to the interaction parameters of the device to be updated.

[0076] For example, for the interaction parameter a of the new device, which corresponds to the interaction parameter a and interaction parameter b of the external interaction device A, and the interaction parameter a and interaction parameter c of the external interaction device B, the value range of the interaction parameter a of the external interaction device A is 1-5, the value range of the interaction parameter a of the external interaction device B is 2-7, the value range of the interaction parameter b of the external interaction device A is 0-1, and the value range of the interaction parameter c of the external interaction device B is 3-10; therefore, for the interaction parameter b, the value range of the interaction parameter a is obtained by the preset conversion coefficient k (0-1) to obtain 0-3; for the interaction parameter c, the value range of the interaction parameter a is obtained by the preset conversion coefficient m (3-10) to obtain 1-6; for the interaction parameter a, the reasonable value range of the interaction parameter a is 2-5; combining the above three value ranges, the reasonable value range of the interaction parameter a is 2-3, that is, the value range corresponding to the interaction parameter of the device to be updated is 2-3.

[0077] The present embodiment provides a management device for old photovoltaic equipment, which realizes accurate calculation of the value range corresponding to the interaction parameters of the equipment to be updated by analyzing and judging the quantity and attributes corresponding to the interaction parameters of the external interaction equipment, so that the interaction parameters corresponding to the updated photovoltaic equipment are guaranteed to be within a reasonable value range, thereby ensuring the coordination and compatibility between the updated photovoltaic equipment and other equipment.

[0078] In some optional 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 table lookup method based on the value range corresponding to the interaction parameter of the device to be updated after the update.

[0080] Specifically, according to the value range corresponding to the interaction parameters of the device to be updated after the update, each component parameter of the corresponding new device (i.e., the device to be updated) is obtained, that is, the value of each component parameter is obtained through relevant standards or table lookup, and the component parameter value range is determined according to the preset new device operation requirements.

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

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

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

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

[0085] The present embodiment provides a management device for old photovoltaic equipment. Based on the value range corresponding to the interactive parameters of the updated equipment, a table lookup method is used to determine the component parameters of the equipment to be updated, thereby achieving rapid and accurate acquisition of the component parameters, so that the selected target photovoltaic equipment can operate normally in the power system.

[0086] In some optional embodiments, the selection unit 1032 is also used to obtain the operating requirements of the target photovoltaic device, obtain the value range corresponding to 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 corresponding to the component parameters of the device to be updated.

[0087] Specifically, according to the photovoltaic field's need for standardization or safety management of photovoltaic equipment, based on the multiple interaction parameters of the new equipment (i.e., the equipment to be updated), the component parameters of each new equipment are obtained by table lookup, and the operating requirements of the current new equipment are obtained to obtain the reasonable value ranges of each component parameter required for the updated equipment (new equipment).

[0088] Furthermore, the operation requirement of the target photovoltaic device is usually the fluctuation range of the photovoltaic device operation parameters, such as the (-10%, +10%) range of the current value, or the (90%-100%) range of the standard value.

[0089] This embodiment provides a management device for old photovoltaic equipment, which obtains the value range corresponding to the component parameters of the equipment to be updated through the operating requirements of the target photovoltaic equipment, so that the component parameters corresponding to the updated equipment are more in line with the equipment operating requirements, thereby ensuring the normal operation of the target photovoltaic equipment in the power system.

[0090] According to an embodiment of the present invention, an embodiment of a management method for old photovoltaic equipment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0091] In this embodiment, a method for managing old photovoltaic equipment is provided, which can be used in the above-mentioned management device for old photovoltaic equipment. Figure 2 is a flow chart of a method for managing old photovoltaic equipment according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0092] Step S201, obtaining component parameters of the current photovoltaic power station through a component parameter analysis module, analyzing the component parameters, and determining the equipment to be updated.

[0093] Step S202, obtaining the interaction parameters of the device to be updated through the interaction parameter updating module, determining the external interaction device based on the interaction parameters of the device to be updated, and obtaining the interaction parameters of the external interaction device, updating the interaction parameters of the device to be updated based on the interaction parameters of the external interaction device, and obtaining the updated interaction parameters of the device to be updated.

[0094] Step S203 : selecting a target photovoltaic device based on the updated interaction parameters of the device to be updated through the management module, and using the target photovoltaic device to perform replacement management on the old photovoltaic device.
