[0022] Among the related technologies, due to the long photovoltaic industry chain, rapid technological iteration, and different construction cycles of each link, the demand for photovoltaic power generation and energy storage is increasing rapidly. At a certain stage, the performance and production capacity of photovoltaic power station equipment may not meet the requirements.

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.

[0025] In this embodiment, a photovoltaic power station equipment upgrade management method is provided, which can be used for the above-mentioned server. Figure 1 is a flow chart of a photovoltaic power station equipment upgrade management method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0026] Step S101, obtaining equipment parameters of each device in the photovoltaic power station and upgrade information corresponding to different types of equipment, wherein the equipment parameters include equipment type, equipment performance parameters before upgrade, equipment performance parameter attenuation rate and service life.

[0027] Exemplarily, a photovoltaic power station may be a photovoltaic power station that performs equipment upgrade management. The photovoltaic power station includes multiple types of equipment. In the embodiment of the present application, each type of equipment generally includes equipment with different functions of the photovoltaic power station, such as photovoltaic components, energy storage equipment, detection equipment, conversion equipment, etc. Each type of equipment corresponds to different upgrade information. The upgrade information is determined according to the actual new needs of the photovoltaic power station, mainly the adjustment information of the equipment parameters.

[0028] Step S102, based on the device category, device performance parameter decay rate and service life of each device, at least one target device that can be upgraded is determined from multiple devices.

[0029] Exemplarily, in an embodiment of the present application, thresholds for the attenuation rate and the service life are determined. When the threshold range is exceeded, it is considered that the device cannot be upgraded and needs to be updated (replaced). If the device does not exceed the thresholds for the attenuation rate and the service life, the corresponding device is determined as a target device that can be upgraded.

[0030] Step S103: determining the target device performance parameters after the target device is upgraded based on the device performance parameters corresponding to the target device before the upgrade and the upgrade information corresponding to the target device.

[0031] Exemplarily, in an embodiment of the present application, based on the device type of the target device, the upgrade information corresponding to the target device is determined, and based on the upgrade information, the performance parameters of the target device after the target device is upgraded are determined.

[0032] Step S104: performing upgrade management on the target device based on the upgraded performance parameters of the target device.

[0033] Exemplarily, in the embodiment of the present application, the target device is upgraded and managed using the upgraded performance parameters of the target device so that the performance of the target device meets the requirements.

[0034] The photovoltaic power station equipment upgrade management method provided in the present embodiment determines the target equipment that can be upgraded in the photovoltaic power station based on the equipment category, equipment performance parameter attenuation rate and service life of each equipment in the photovoltaic power station, and determines the target equipment performance parameters after the target equipment is upgraded based on the upgrade information corresponding to the different categories of equipment and the equipment performance parameters of the target equipment before the upgrade, and manages the target equipment based on the upgraded target equipment performance parameters, thereby realizing timely upgrade of the equipment parameters of the equipment that can be upgraded in the photovoltaic power station and ensuring that the equipment performance and production capacity of the photovoltaic power station meet the current technical requirements.

[0035] In this embodiment, a photovoltaic power station equipment upgrade management method is provided, which can be used for the above-mentioned server. Figure 2 is a flow chart of a photovoltaic power station equipment upgrade management method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0036] Step S201, obtaining the equipment parameters of each device in the photovoltaic power station and the upgrade information corresponding to different types of equipment, the equipment parameters include equipment type, equipment performance parameters before upgrade, equipment performance parameter attenuation rate and service life. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0037] Step S202: determining at least one target device that can be upgraded from a plurality of devices based on the device category, device performance parameter decay rate, and service life of each device.

[0038] Specifically, the above step S202 includes:

[0039] Step S2021, obtaining upgrade constraint information corresponding to different types of equipment, wherein the upgrade constraint information includes device performance parameter attenuation rate thresholds and service life thresholds corresponding to different types of equipment.

[0040] Exemplarily, in an embodiment of the present application, before the equipment is upgraded, the equipment type and the corresponding equipment performance parameter attenuation rate and service life are determined through equipment parameters, and the thresholds of the attenuation rate and service life are determined based on the requirements of the type of photovoltaic field to which the current equipment belongs.

[0041] Step S2022, based on the device performance parameter decay rate, service life of each device and the device performance parameter decay rate threshold and service life threshold of the corresponding device, at least one target device that can be upgraded is determined from multiple devices.

[0042] Exemplarily, in the embodiment of the present application, when the device performance parameter attenuation rate and service life of the device do not exceed the threshold range, it is considered that the device can be upgraded.

[0043] Step S203: Determine the target device performance parameters after the target device is upgraded based on the device performance parameters before the upgrade corresponding to the target device and the upgrade information corresponding to the target device. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0044] Specifically, the above step S203 includes:

[0045] Step S2031, obtaining a predicted value of a performance parameter degradation of a target device.

[0046] Exemplarily, in an embodiment of the present application, the predicted value of the performance parameter degradation of the target device can be determined by historical information on changes in the device performance parameters.

[0047] Step S2032: determining a value range of the device performance parameter of the target device based on the predicted value of the performance parameter degradation of the target device and the device performance parameter before the upgrade.

[0048] Exemplarily, in the embodiment of the present application, based on the predicted value of the performance parameter degradation of the target device and the device performance parameter before the upgrade, the value range of the device performance parameter can be determined, including the maximum value and the minimum value (min, max).

[0049] Step S2033: determining the target device performance parameters after the target device is upgraded based on the device performance parameter value range of the target device and the upgrade information.

[0050] In some optional implementations, the above step S2033 includes:

[0051] Step a1: determining a target device performance parameter value range after the target device is upgraded based on the device performance parameter value range of the target device and the upgrade information.

[0052] Exemplarily, in the embodiment of the present application, the required parameter value range after the upgrade is calculated based on the upgrade information (increase and decrease of fixed values ​​or percentages).

[0053] Step a2: if there is an overlap between the device performance parameter value range of the target device and the target device performance parameter value range, determine the target device performance parameters after the target device is upgraded based on the device performance parameter value range and the target device performance parameter value range.

[0054] Exemplarily, in an embodiment of the present application, the target device may include multiple performance parameters that need to be adjusted. If there is an overlapping range between the value ranges of the device performance parameters of the multiple parameters that need to be adjusted of the target device and the value range of the target device performance parameters, it is considered that the target device can be upgraded, and the parameters are adjusted based on the value range of the target device performance parameters to determine the target device performance parameters after the upgrade.

[0055] In some optional embodiments, the method further comprises:

[0056] Step b1, based on the device category, device performance parameter decay rate and service life of each device, determine the devices that cannot be upgraded among the multiple devices as devices to be updated. Exemplarily, in an embodiment of the present application, when the device performance parameter decay rate and / or service life of the device exceeds the threshold range, it is considered that the device cannot be upgraded and needs to be updated (replaced). For example, the current device is an energy storage device, which is a core device. If the parameter decay rate exceeds 20% and the service life exceeds 5 years, it is considered that the energy storage device cannot be upgraded and needs to be updated.

[0057] Step b2, if there is no overlap between the device performance parameter value range of the target device and the target device performance parameter value range, determine whether the target device is a device to be updated, and obtain a judgment result. Exemplarily, in an embodiment of the present application, if there is no overlap between the device performance parameter value range of one or more parameters and the target device performance parameter value range, the adjustment range of the target device performance parameter value range of the parameter is determined according to the current device level, and the new target device performance parameter value range is calculated according to the adjustment range. Subsequently, a value range judgment is performed based on the new target device performance parameter value range and the device performance parameter value range. If the required value range of the new parameter partially overlaps with the actual maximum value range, the parameter adjustment and device upgrade work are continued. If there is still no overlap, the current device upgrade work is stopped and marked as a device that needs to be updated (replaced). In order to ensure the overall operating efficiency and safety of the power station, the target device performance parameter value range of the core equipment of the photovoltaic power station cannot be adjusted. If there is no overlap between the device performance parameter value range of one or more parameters and the target device performance parameter value range, and the level of the target device is greater than the preset level, and the target device meets the preset conditions, the target device will be treated as a device to be updated. The preset level can be determined based on demand.

[0058] Step b3: determining a value range of a device performance parameter of the updated device based on the device type of the device to be updated.

[0059] For example, in the embodiment of the present application, for the device to be updated, the type of the device is determined, and the new parameter value range of the upgraded device of the type is obtained as the recommended parameter value range after the current device is updated. If there is no upgraded device of the type to which the device belongs, the parameter value range is selected based on historical data or pre-defined standard data.

[0060] The photovoltaic power station equipment upgrade management method provided by the present invention is described below through a specific embodiment.

[0061] Example:

[0062] Device A is a device to be upgraded, and belongs to the energy storage device type. According to the system parameters of device A, the attenuation rate of the parameters is 2%, and the service life is 1 year, which meets the standard that the attenuation rate of the device to be upgraded does not exceed 10%, and the service life does not exceed 5 years. It is an upgradeable device. The parameters to be upgraded of device A are parameter a, parameter b, and parameter c. The current actual value ranges are (10-15), (30-50), and (100-150) respectively. The maximum value ranges (min-max) of parameter a, parameter b, and parameter c in device A are (30-50), (35-60), and (115-170) respectively.

[0063] Case 1: The upgrade information is that for energy storage type equipment, the value range of parameters a and b increases by 20, and the value range of parameter c expands by 10% (that is, the minimum value decreases by 10%, and the maximum value increases by 10%);

[0064] Based on the upgrade information, the required parameter value ranges of the upgraded parameter a (+10), parameter b (+10), and parameter c (-10%, +10%) are calculated, which are (20-25), (40-60), and (90-165), respectively;

[0065] After comparing the required parameter value range with the maximum value range, it is determined that the value ranges of the three parameters are completely or partially overlapped, and all of them are upgradeable parameters, that is, the device is an upgrade device.

[0066] Get the value ranges of the upgrade parameters: parameter a (20-25), parameter b (40-60), and parameter c (115-165).

[0067] Case 2: The upgrade information is that for energy storage type equipment, the value range of parameters a and b increases by 35, and the value range of parameter c expands by 20% (that is, the minimum value decreases by 20%, and the maximum value increases by 20%);

[0068] Based on the upgrade information, the required parameter value ranges of the upgraded parameter a (+35), parameter b (+35), and parameter c (-20%, +20%) are calculated, which are (45-50), (65-85), and (80-180), respectively;

[0069] After comparing the required parameter value range with the maximum value range, it is determined that the value ranges of parameter a and parameter c overlap in whole or in part, and are parameters that can be upgraded;

[0070] However, the value range of parameter b does not overlap, and device A is a core device of the photovoltaic power station with a high level of importance. Therefore, in order to ensure the overall operating efficiency and safety of the power station, the parameter value range of the high-level equipment cannot be changed, that is, the device is a non-upgradeable device, that is, a device to be updated (replaced) (device A is an energy storage device).

[0071] If device A is a detection device, that is, it is in the important level of the photovoltaic power station, so on the basis of the normal operation of the high-level core equipment, the value range of the medium-level equipment can be adjusted by 10%. That is: the required parameter value range (65-85) of the upgraded parameter b calculated based on the upgrade information is adjusted to the required parameter value range (58-76) and the maximum value range (35-60), which partially overlaps and meets the upgrade parameter requirements, that is, the device belongs to the upgraded device (device A is a detection device).

[0072] Therefore, the value ranges of the upgrade parameters are obtained as parameter a (45-50), parameter b (58-60), and parameter c (115-170).

[0073] Device update step: After analyzing the devices to be updated based on the system parameters of the devices and calculating the parameter value ranges based on the upgrade information, device parameter recommendations are made for the above-mentioned updated devices as the basis for parameter selection for subsequent device updates (replacements). Specifically:

[0074] For the device to be updated, determine the type of the device, and obtain the new parameter value range of the upgraded device of the type as the recommended parameter value range of the current device after the update. If there is no upgraded device of the type to which the device belongs, select the parameter value range based on historical data or pre-defined standard data.
