[0045] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, the following will describe in detail exemplary embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described herein.

[0046] See also Figure 1 , a wind power control system, comprising:

[0047] The wind turbine unit 101 is used to collect the output power of the wind turbine and transmit the electricity generated by the wind turbine to the power grid;

[0048] The photovoltaic unit 102 is used to collect the output power of the photovoltaic generator and transmit the electricity generated by the photovoltaic generator to the power grid when the power boost strategy is executed to increase the output power of the wind farm to the power grid;

[0049] The energy storage unit 103 is connected to the wind turbine unit and the photovoltaic unit respectively, and is used to store the electric energy generated by the wind turbine and the photovoltaic generator, and absorb and store the electric energy to reduce the output power of the wind farm to the grid when the power reduction strategy is implemented;

[0050] The control unit 104 is connected to the wind turbine unit, the photovoltaic unit and the energy storage unit respectively, and is used to:

[0051] When it is monitored that the output power of the wind turbine unit reaches a first preset power, the energy storage unit is controlled to execute a power reduction strategy to reduce the output power of the wind farm to the grid to a second preset power;

[0052] When it is detected that the output power of the wind turbine unit is lower than the third preset power, the photovoltaic unit is controlled to execute a power boosting strategy to increase the output power of the wind farm to the grid to the second preset power;

[0053] The third preset power is smaller than the second preset power, and the second preset power is smaller than the first preset power.

[0054] In the wind power control system of the disclosed embodiment, when the control unit monitors that the output power of the wind turbine unit reaches a first preset power, the control unit controls the energy storage unit to execute a power reduction strategy, so that the power output from the wind farm to the power grid is reduced to a second preset power; when the output power of the wind turbine unit is lower than the third preset power, the control unit controls the photovoltaic unit to execute a power boosting strategy, so that the output power is increased to the second preset power, thereby stabilizing the power output from the wind farm to the power grid.

[0055] It is understandable that the first preset power and the second preset power are preset according to demand. The first preset power is the threshold corresponding to the power reduction strategy, and the second preset power is a value within the output power range of the wind turbine operating parameters. The second preset power can be set to the minimum value within the output power range of the wind turbine, and the value of the first preset power is positively correlated with the range (such as 80% to 90% of the rated value). For example, for a wind turbine with an output power of 500 kW to 1000 kW, the first preset power is 800 kW.

[0056] It is understood that the third preset power can be pre-set based on demand. The third preset value can be set according to the demanded power of the wind farm output grid, and is positively correlated with the demanded power. Optionally, the third preset power is set to 1 / n of the demanded power of the wind farm output grid, where n is greater than 1. For example, n can be set to 5. If the demanded power of the wind farm output grid is 1000 kilowatts, the third preset power is 200 kilowatts; if the demanded power of the wind farm output grid is 2000 kilowatts, the third preset power is 400 kilowatts; and if the demanded power of the wind farm output grid is 3000 kilowatts, the third preset power is 600 kilowatts.

[0057] When the wind speed is too low, the output power of the wind turbine generator set is less than the minimum rated power. In order to ensure that the wind farm outputs the required power to the grid, adjustment is required. The third preset power is positively correlated with the required power.

[0058] In one example, in an example of the present application, a wind turbine unit 101 is configured to collect the output power of a wind turbine and transmit the electricity generated by the wind turbine to a power grid. Specifically, this may be transmitting the electricity generated by the wind turbine to a wind farm output grid, such as a wind farm grid connection point. This wind turbine unit 101 may be a wind turbine model unit.

[0059] In one example of the present application, photovoltaic unit 102 is configured to collect the output power of a photovoltaic generator and, when executing a power boost strategy, transmit the generated power to the power grid to increase the wind farm's output power to the grid. Specifically, upon receiving a power boost strategy execution instruction from a control unit, photovoltaic unit 102 transmits the generated power to the power grid to increase the power output of the grid. This photovoltaic unit 102 may be a photovoltaic model unit.

[0060] In one example of the present application, the energy storage unit 103 is connected to the wind turbine unit and the photovoltaic unit, respectively, and is used to store the electric energy generated by the wind turbine and the photovoltaic generator, and absorb and store electric energy to reduce the output power of the wind farm output grid when the power reduction strategy is executed. A number of batteries can be set in the energy storage unit 103. When the energy storage unit 103 receives an instruction from the control unit to execute the power reduction strategy, it can absorb the energy generated by the wind turbine delivered by the wind turbine unit. Similarly, in actual applications, the energy storage power supply can also absorb the energy generated by the photovoltaic generator. The energy storage unit 103 can be an energy storage model unit.

[0061] In one example of the present application, the control unit 104 is connected to the wind turbine unit, the photovoltaic unit and the energy storage unit, respectively. The control unit is also used to: construct a three-dimensional operation model (or a three-dimensional summary model) based on the wind turbine operating parameters of the wind turbine, the photovoltaic operating parameters of the photovoltaic generator and the storage status of the energy storage unit (its battery), and perform system testing based on the three-dimensional operation model. The test may include a strategy test or a model test. During the test, devices with abnormal output power can be marked as alarm devices. It can be understood that the control unit can be called a three-dimensional engine control unit.

[0062] Accordingly, the control unit is used to mark devices with abnormal output power as alarm devices when performing system testing based on the three-dimensional operation model. The system includes a device maintenance unit connected to the control unit 104 for repairing alarm devices.

[0063] The 3D operational model features digital panoramic roaming, which allows users to teleport and navigate within the model, viewing equipment operating parameters and video surveillance footage. A fully charged state indicates when the battery is fully charged. Model testing includes digital panoramic roaming, virtual maintenance training, graphical model navigation, and test management. This invention utilizes a 3D engine control unit to model wind turbines, enabling more intuitive monitoring of the operational status of each unit. By enabling digital panoramic roaming, virtual maintenance training, graphical model navigation, and test management within the 3D model, the accuracy and practicality of the wind farm simulation test platform are effectively improved.

[0064] The control unit builds a model for each device to perform data fusion, forming a three-dimensional cockpit for monitoring the equipment status, and pushes the collected data to the three-dimensional cockpit to determine whether there is any abnormality in the equipment. The three-dimensional cockpit can combine abnormal data and historical data to push equipment maintenance plans to the equipment maintenance unit.

[0065] In an example of the present application, the control unit includes a wind turbine monitor, which is connected to the wind turbine unit and is used to monitor the output power of the wind turbine unit.

[0066] The control unit includes an energy storage monitor connected to the energy storage unit and used for monitoring the power storage state of the energy storage unit.

[0067] The control unit includes a three-dimensional modeler, which is connected to the wind turbine monitor, the photovoltaic generator monitor and the battery monitor respectively, and is used to establish a three-dimensional operation model of the wind farm according to the monitored data.

[0068] Specifically, by monitoring the output power of different units, the output power of each unit can be effectively adjusted, and the battery's storage capacity can be used to recover the output of wind and photovoltaic power generation, further improving the accuracy and practicality of the control system. It can be seen that when the control unit has the ability to build a three-dimensional operating model and has testing functions, the control system can also be called a wind farm simulation test system.

[0069] In one example, the system includes a power reduction unit, connected to the wind turbine unit and the control unit, for controlling the wind turbine to reduce its output power when executing a power reduction strategy. The control unit is configured to, upon detecting that the energy storage unit is fully charged, control the power reduction unit to execute the power reduction strategy and reduce the wind turbine's output power. The system monitors the energy storage unit's status in real time through the control unit. When the control unit detects that the energy storage unit is fully charged, it triggers the power reduction unit to execute the power reduction strategy and control the wind turbine to reduce its output power, thereby avoiding energy storage overload or grid fluctuations caused by excess electricity and improving the safety and stability of system operation.

[0070] Specifically, the energy reduction unit may include a blade adjuster connected to the wind turbine to increase the pitch angle of the wind turbine blades, and a brake connected to the wind turbine to increase the resistance on the wind turbine blades. When the energy storage unit is full, the wind turbine's power generation capacity is effectively reduced, preventing excess energy from being fed into the grid or damaging the energy storage system, ensuring safe system operation and improving power regulation accuracy.

[0071] See also Figure 2 A wind power control method is applied to any wind power control system of the embodiments of the present disclosure, the method comprising:

[0072] S201, monitoring the output power of the fan unit;

[0073] S202, when it is monitored that the output power of the wind turbine unit reaches a first preset power, controlling the energy storage unit to execute a power reduction strategy to reduce the output power of the wind farm to the grid to a second preset power;

[0074] S203, when it is monitored that the output power of the wind turbine unit is lower than the third preset power, controlling the photovoltaic unit to execute a power boosting strategy to increase the output power of the wind farm to the grid to a second preset power;

[0075] The third preset power is smaller than the second preset power, and the second preset power is smaller than the first preset power.

[0076] In one example, the method further includes:

[0077] Monitor the storage status of the energy storage unit;

[0078] When it is detected that the energy storage unit is in a fully charged state, the power trigger strategy is triggered to control the energy reduction unit to reduce the output power of the wind turbine.

[0079] In one example, the method further includes:

[0080] A three-dimensional operating model is constructed based on the wind turbine operating parameters of the wind turbine, the photovoltaic operating parameters of the photovoltaic generator, and the energy storage unit's power state. System testing is then performed based on this three-dimensional operating model. During this system testing, devices with abnormal power output can be identified.

[0081] System testing using a three-dimensional operating model can include digital panoramic roaming, virtual maintenance training, graphic model navigation, and test management.

[0082] It's understandable that digital panoramic roaming uses 3D modeling technology to recreate a realistic site work scene at a 1:1 scale. It allows users to teleport and roam within wind farms and wind turbines, view equipment descriptions, real-time operating data, and video surveillance footage, and assist frontline workers in control rooms and offices with a first-person perspective to efficiently, quickly, and accurately grasp the true state of on-site equipment and the environment. It also allows users to enter the interior of wind turbines, roam around the tower base and within the nacelle, switch between multiple perspectives, and hide the nacelle cover, making it easier to understand the structure of wind turbines and the process flow and principles of wind turbine operation under normal operating conditions.

[0083] It is understandable that virtual maintenance training is visual maintenance training for important equipment, and relies on three-dimensional modeling technology and virtual reality technology to carry out structured modeling of important equipment, and conduct visual training from the basic information of the equipment, component structure, working principle, etc.

[0084] It can be understood that the image-model navigation is to realize the linkage between 2D drawings and 3D models, and can call and view 2D drawings and other equipment documents in the 3D scene. It realizes compatibility and online preview of information from multiple information sources and formats.

[0085] It can be understood that examination management includes user group management, personnel management, user screening, user export, user modification, test question classification, test question import, test question management, examination list, examination creation, examination results viewing, and examination record functional modules to realize the function of personnel answering examination questions online.

[0086] In one example, by building models for each device and performing data fusion, a three-dimensional cockpit for monitoring the device status is formed;

[0087] Push the collected data to the 3D cockpit to determine whether there is any abnormality in the equipment;

[0088] The three-dimensional cockpit combines abnormal data and historical data to push equipment maintenance plans.

[0089] In one example, the method further includes:

[0090] Mark the device with abnormal output power as an alarm device and repair the alarm device.

[0091] The exemplary embodiments of the present disclosure further provide an electronic device including: at least one processor; and a memory communicatively connected to the at least one processor. The memory stores a computer program executable by the at least one processor, which, when executed by the at least one processor, causes the electronic device to perform a method according to an exemplary embodiment of the present disclosure.

[0092] In the disclosed embodiment, by monitoring the output power of different units, the output power of different units is effectively adjusted, and the production capacity of wind power and photovoltaic power generation is recovered through the storage capacity of the storage unit, further improving the accuracy and practicality of the control system.

[0093] By setting up a control unit to model the wind turbines, the operating status of each unit can be monitored more intuitively. By performing digital panoramic roaming, virtual maintenance training, graphic model navigation and examination management in the three-dimensional operation model, the accuracy and practicality of the wind farm simulation test platform are effectively improved.

[0094] By comprehensively monitoring and simulating wind farm equipment, environments, and operating parameters through digital twin technology, early warning of wind turbine maintenance and repairs can be achieved, accurately predicting the occurrence and repair time of wind turbine equipment failures. This can reduce losses caused by equipment failures in wind farms and lower equipment maintenance costs, further improving the accuracy and practicality of the wind farm simulation test platform.
