[0041] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0042] The control method, apparatus, electronic device, and storage medium of the photovoltaic power generation system according to embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0043] Figure 1 is a schematic flowchart of a control method for a photovoltaic power generation system provided in an embodiment of this disclosure.

[0044] As shown in Figure 1, the method includes the following steps:

[0045] Step 101: Obtain external access requests; wherein, an external access request contains at least one access target.

[0046] In some embodiments, an external access request is a request from a user, device, or system outside the network (i.e., outside the internal network or a trusted area) to access specific resources, services, or information. In some embodiments, these requests may be from pre-determined devices or users, or originate from any location on the Internet. Specifically, this application does not limit this.

[0047] An access target refers to the specific object or resource that an external access request expects to access. This can be a file, database entry, web page, API endpoint, etc. on a server, or the operating status of a specific device, control system, etc. Each access target has its specific permissions and security requirements to ensure that only authorized requests can successfully access the data, thereby protecting data security.

[0048] Step 102: Authenticate the external access request, and after successful authentication, forward the external access request to the access target corresponding to the external access request.

[0049] In some embodiments, upon receiving an external access request, it is necessary to verify the legitimacy of the user or device initiating the request. This may involve checking the username and password, digital certificate, token, or other forms of authentication. Only requests that have been successfully authenticated will be allowed to proceed further.

[0050] The verification process succeeds when the identity information provided in an external access request matches the information stored in the system. This signifies that the requester is trustworthy and authorized to access the requested resource. After the external access request is authenticated, the system redirects it to the appropriate access target.

[0051] The control method for a photovoltaic power generation system disclosed herein mainly includes: acquiring an external access request; wherein, at least one access target exists in an external access request; authenticating the external access request, and forwarding the external access request to the access target corresponding to the external access request after successful authentication. Compared with related technologies, the embodiments of this application ensure that only authenticated requests are processed and forwarded to the corresponding target by remotely monitoring and verifying external access requests. This remote control capability not only improves system security but also enhances flexibility and response speed. Administrators can update security policies in real time and quickly respond to new threats or abnormal behaviors without physical contact with the server. In addition, remote management reduces the need for on-site maintenance, lowers operation and maintenance costs, and allows for more efficient troubleshooting and problem solving.

[0052] In some embodiments, the following steps are included before obtaining an external access request:

[0053] Acquire data information uploaded by photovoltaic power stations and / or booster stations, and display the data information on a preset display panel.

[0054] In some embodiments, the data information includes various operating parameters and performance indicators of the photovoltaic power station and the booster station, such as power generation, efficiency, temperature, and irradiance, which are crucial for monitoring and managing the operation of the photovoltaic system.

[0055] In some embodiments, a preset display panel is used to graphically display specific data or information. The display panel shows real-time data, historical trends, performance analysis, and other information of the photovoltaic power station and booster station. Users can understand the operating status of the photovoltaic system and manage its operation from the preset display panel.

[0056] In some embodiments, data may be displayed in various forms, including charts, graphs, numerical indicators, etc., so that users can quickly obtain key information and make decisions.

[0057] In some embodiments, after obtaining data information from the photovoltaic power station and the booster station, the efficiency of the photovoltaic power station and the operating status of the booster station can be evaluated based on the data information. Combined with microgrid demand analysis, the power consumption trend can be predicted, and resources can be rationally allocated to generate control commands for the photovoltaic power station and the booster station, such as adjusting the tilt angle of the photovoltaic panels to adjust the power generation, or adjusting the output of the inverter to match the grid demand, etc. Specifically, this application embodiment does not limit this.

[0058] In some embodiments, the access request includes multiple types, such as accessing the real-time operating status of a specific device, controlling the device, or accessing data. When the external access request is for data access, the step of authenticating the external access request and, upon successful authentication, forwarding the external access request to the corresponding access target includes the following steps:

[0059] After the external access request is successfully authenticated, the access target data of the external access request is sent to the sending end of the external access request.

[0060] In some embodiments, upon successful authentication, the system processes the external access request and retrieves the required data from the appropriate access target (such as a database, file, API, etc.). This data may be static, such as web page content or files, or dynamic, such as database query results. The access target data is sent back to the source so that the requester can receive the information or service they requested.

[0061] In some embodiments, data transmission can be achieved through HTTP response, WebSocket connection or other communication protocols, or it can be transmitted using the TCP / IP network protocol. Specifically, the embodiments of this application do not limit this.

[0062] In some embodiments, the sender of the external access request may be a display panel or user interface. In this case, the target data will be sent to this display panel so that the user can view and interact with it directly on their device. The display panel may present the data in the form of charts, lists, or other formats, providing an intuitive way to understand and analyze information. Specifically, this application embodiment does not limit this.

[0063] In some embodiments, the preset display panel can not only display data information, but also allow maintenance personnel to issue control commands from the preset display panel to control the photovoltaic power station and / or booster station, specifically including the following steps:

[0064] The control command is obtained from the preset display panel and pushed to the control target according to the preset communication channel; wherein, the control target includes a photovoltaic power station and / or a booster station.

[0065] The control command is obtained from the preset display panel and pushed to the control target according to the preset communication channel; wherein, the control target includes a photovoltaic power station and / or a booster station.

[0066] In some embodiments, operators can input specific commands via a display panel to adjust the photovoltaic system's operating mode, optimize performance, or respond to changes in external conditions. For example, control commands may include starting / stopping power generation, adjusting power output, and switching operating modes.

[0067] In some embodiments, communication paths may be pre-configured to ensure secure transmission of control commands. These channels may be based on wired (e.g., Ethernet) or wireless (e.g., Wi-Fi, cellular networks) technologies and employ encryption measures to protect the security of data transmission.

[0068] In some embodiments, the above method further includes the following steps:

[0069] The data information uploaded by the photovoltaic power station and / or booster station, the control commands, and the external access requests are stored.

[0070] In some embodiments, the data information may include various operating parameters and performance indicators collected from the photovoltaic power plant and / or booster station, such as power generation, efficiency, temperature, and irradiance. Control commands may include starting / stopping power generation, adjusting power output, and switching operating modes. These data information, control commands, and external access requests are stored in a database or file system to facilitate subsequent analysis, auditing, and retrospective analysis, and to ensure that this information can be quickly retrieved and processed when needed.
