[0029] Step S102, obtaining working status information of the photovoltaic station.

[0030] The working status information includes different types of operating status parameters of photovoltaic stations.

[0031] The above-mentioned photovoltaic stations may refer to facilities that can utilize solar energy to generate electricity, by installing solar photovoltaic panels to convert solar energy into electrical energy. Photovoltaic stations can be divided into distributed photovoltaic stations and centralized photovoltaic stations. Distributed photovoltaic stations can be built on roofs, fields and other places, while centralized photovoltaic stations can be built in open areas and transmit the generated electricity to cities or industrial areas through transmission lines. The specific type of photovoltaic station can be determined according to actual needs and is not limited here.

[0032] The above-mentioned edge cluster platform may refer to a cluster management platform based on edge computing technology, which is used to manage and deploy applications and services distributed on edge devices. Edge computing may be a technology that stores computing resources and data close to end users or data sources, which can respond to user requests faster and reduce data transmission delays. The edge cluster platform may include the following main components: edge nodes, cluster managers, application managers, and data managers. Among them, edge nodes may refer to physical or virtual nodes deployed on edge devices for running applications and services. The cluster manager may be responsible for managing the cluster management system of edge nodes, including resource scheduling, fault tolerance management, monitoring, and automated deployment. The application manager may be used to manage and deploy applications and services to edge nodes, including application lifecycle management, version control, configuration management, and other functions. The data manager may be used to manage data storage and data processing on edge nodes, including data backup, data synchronization, data distribution, and other functions. The use of an edge cluster platform can improve the system's response speed and performance, reduce data transmission costs, and enhance data security and privacy protection.

[0033] The above-mentioned working status information may refer to various operating states and performance data of the photovoltaic station, which may include but is not limited to parameter information such as output current, output power, output frequency, power generation, power generation efficiency, etc. of the photovoltaic station. The working status information can be determined according to actual needs and is not limited here.

[0034] In an optional embodiment, by monitoring and collecting the working status information of the photovoltaic station, the working status of the photovoltaic system can be understood in real time, helping the operation and maintenance personnel to discover problems in time and take measures to adjust and optimize. Specifically, monitoring equipment such as data collectors, sensors, etc. can be installed in the photovoltaic station for real-time monitoring and collection of operating status parameters of the photovoltaic system, including power generation power, voltage, current, temperature, etc. The monitored data can be displayed on the monitoring platform in the form of charts, curves, etc. to achieve data visualization, which is convenient for the operation and maintenance personnel to intuitively understand the operating status of the photovoltaic station. Through the above steps, the working status information of the photovoltaic station can be obtained, which helps the operation and maintenance personnel to discover and solve problems in time, and provide a data basis for the subsequent output power control of the photovoltaic station.

[0035] Step S104: determining the operating status level of the photovoltaic station based on the limit parameters in the working status information.

[0036] The limit value parameters are used to indicate that the corresponding parameter values ​​during the operation of the photovoltaic station need to be within the preset value range.

[0037] The above preset value range can be determined according to the specific type of the limit parameter and is not limited here.

[0038] The above-mentioned limit parameters may refer to part of the parameter information in the working status information that can be used to determine the operating status of the photovoltaic station. For example, the limit parameters may refer to parameter information such as the output current and output voltage of the photovoltaic station. The specific type of the limit parameters can be determined according to actual needs and is not limited here.

[0039] The above-mentioned operating status level can represent different operating conditions of the photovoltaic station based on different status levels. The higher the operating status level, the better the operating condition of the photovoltaic station; when the operating status level is low, it can be indicated that the photovoltaic station is in a fault state, etc. The setting of the operating status level can be determined according to actual needs and is not limited here.

[0040] In an optional embodiment, when determining the operating status level of a photovoltaic station, the present application may first determine a limit parameter that can be used to determine the operating status of the photovoltaic station, and may determine a preset value range for the specifically determined limit parameter, which may include an allowable maximum value and minimum value, as well as a threshold value of a normal range. The value of the limit parameter during the operation of the photovoltaic station may be monitored in real time by sensors and other equipment to obtain real-time data, and the value of the limit parameter obtained in real time may be compared with the preset value range to determine whether the parameter is within the normal range. The operating status level of the photovoltaic station may be determined based on the state of the limit parameter, such as high efficiency, good, normal, warning or fault level, so as to facilitate taking corresponding measures for adjustment and control based on the determined operating status level to ensure the normal operation and power generation efficiency of the photovoltaic station. Through the above steps, the operating status level of the photovoltaic station may be determined based on the limit parameters in the working status information, to provide support for subsequent output power control of the photovoltaic station.

[0041] Step S106, when the operating status level is less than or equal to the preset operating status level, the power generation of the photovoltaic station is controlled based on the first adjustment setting value, and abnormal operation prompt information is generated and transmitted to the remote data processing center.

[0042] The above-mentioned preset operating status level can be used to measure the operating status level of the photovoltaic station. For example, when the operating status level is less than or equal to the preset operating status level, it can be determined that the photovoltaic station is in a warning or fault state; when the operating status level is greater than the preset operating status level, it can be determined that the photovoltaic station is in a normal state or above. The specific setting of the preset operating status level can also be determined according to actual needs and is not limited here.

[0043] The above-mentioned first adjustment set value may refer to a power generation set value pre-set on the edge cluster platform. The first adjustment set value may be set to zero, or a value close to zero, etc., and may be used to control the photovoltaic station to stop operating, or to operate at a lower output power. The first adjustment set value may be determined according to actual needs and is not limited here.

[0044] The above-mentioned abnormal prompt information may refer to the warning information automatically issued by the system when the operating status level of the photovoltaic station is less than or equal to the preset operating status level. The abnormal prompt information may indicate different types of operating conditions of the photovoltaic station, including but not limited to electrical failures, communication failures, temperature abnormalities, etc. of the photovoltaic station. The abnormal prompt information may be determined according to the specifically determined limit parameters, which are not limited here. When the operating status level of the photovoltaic station is less than or equal to the preset operating status level, the system may automatically issue corresponding prompt information according to the specific situation to help the operation and maintenance personnel quickly locate the problem and take corresponding measures to repair it, thereby ensuring the normal operation of the photovoltaic station.

[0045] The above-mentioned remote data processing center may refer to a centralized data processing facility set up corresponding to the edge cluster platform, which can provide data storage, processing, analysis and management services. The remote data processing center may have more powerful computing power and storage resources than the edge cluster platform, and may support large-scale data processing and analysis. It may also provide higher security and reliability. The remote data processing center may cooperate with the edge cluster platform to realize data transmission and sharing through network connection, so as to achieve more efficient data processing and management.

[0046] In an optional embodiment, a preset operating status level can be set to guide the power generation control of the photovoltaic station. When the operating status level of the photovoltaic station is less than or equal to the preset operating status level, the operating status data of the photovoltaic station can be obtained in real time through the monitoring equipment and system, and the real-time obtained operating status data can be compared with the preset operating status level. When the operating status level of the photovoltaic station is less than or equal to the preset operating status level, the power generation of the photovoltaic station can be adjusted according to the first adjustment setting value. For example, the first adjustment setting value can be set to zero, or a value close to zero, etc., which can be used to control the photovoltaic station to stop operating or operate at a lower output power; at the same time, the system can generate abnormal operation prompt information, including the current operating status, power generation adjustment status, abnormal reasons, etc., and transmit this information to the remote data processing center. After receiving the abnormal prompt information, the remote data processing center will analyze and process it, including adjusting the control parameters of the photovoltaic station, issuing an alarm notification, formulating further processing plans, etc., to ensure the safe and stable operation of the photovoltaic station.

[0047] Step S108, when the operating status level is greater than the preset operating status level, the working status information is transmitted to the remote data processing center, and the power generation power of the photovoltaic station is adjusted based on the second adjustment setting value transmitted from the remote data processing center.

[0048] The second adjustment setting value is generated by the remote data processing center based on the working status information, and the second adjustment setting value is greater than the first adjustment setting value.

[0049] The above-mentioned second adjustment setting value can be dynamically determined by the remote data processing center according to the working status information of the photovoltaic station. Since the process of dynamically determining the second adjustment setting value based on the working status information requires more computing resources, the working status information can be transmitted to the remote data processing center with greater computing power and storage resources for processing. The remote data processing center can send the determined second adjustment setting value directly to the edge cluster platform, and the edge cluster platform can directly control the power generation power of the photovoltaic station based on the second adjustment setting value.

[0050] In an optional embodiment, when the monitoring system detects that the operating status level of the photovoltaic station is greater than the preset operating status level, the system can automatically transmit the working status information to the remote data processing center. After receiving the working status information, the remote data processing center can analyze the actual situation of the photovoltaic station and determine the second adjustment setting value according to the set algorithm. The second adjustment setting value is determined according to the actual situation and operating requirements of the station, and may include adjusting the tilt angle of the photovoltaic module, adjusting the working mode or power output of the inverter, etc. The remote data processing center sends the second adjustment setting value to the edge cluster platform, and the edge cluster platform can adjust the power generation power of the photovoltaic station according to the received second adjustment setting value. Through the above process, the photovoltaic station can realize timely adjustment when the actual operating status exceeds the preset operating status level, ensure the safe and stable operation of the equipment and improve the power generation efficiency. The participation of the remote data processing center can also provide more accurate adjustment strategies and optimization solutions to maximize the power generation potential of the photovoltaic station.

The method comprises: obtaining working status information of the photovoltaic station, wherein the working status information comprises different types of operating status parameters of the photovoltaic station; determining the operating status level of the photovoltaic station based on limit parameters in the working status information, wherein the limit parameters are used to indicate that the corresponding parameter values ​​need to be within a preset numerical range during the operation of the photovoltaic station; when the operating status level is less than or equal to the preset operating status level, controlling the power generation of the photovoltaic station based on a first adjustment setting value, and generating abnormal operation prompt information to be transmitted to a remote data processing center; when the operating status level is greater than the preset operating status level, transmitting the working status information to the remote data processing center, and adjusting the power generation of the photovoltaic station based on a second adjustment setting value transmitted from the remote data processing center, wherein the second adjustment setting value is generated by the remote data processing center based on the working status information, and the second adjustment setting value is greater than the first adjustment setting value.

In particular, the present application collects the working information of power generation of each photovoltaic station through the edge cluster platform, and makes abnormal judgments on each photovoltaic power generation on the spot, thereby reducing the work of information transmission and effectively improving working reliability; the working status information of the photovoltaic stations with normal working status and above is then transmitted to the remote data processing center. The remote data processing center can dynamically determine the corresponding second adjustment set value according to the actual working status of the photovoltaic station power generation, and adjust the power of the photovoltaic station to ensure that the photovoltaic power station can automatically respond to the needs of the power grid and output high-quality electric energy. Through the above steps, the efficiency and accuracy of controlling the power generation of the photovoltaic station can be effectively improved, and the intelligent management and optimization adjustment of the photovoltaic station can be realized, thereby solving the technical problem of low efficiency and accuracy in controlling the power generation of the photovoltaic station in the related technology.
