[0088] A dynamic power allocation model for hydrogen-electric hybrid UAV network transmission is established to analyze the characteristic data of hydrogen-electric hybrid UAV status monitoring and determine the dynamic power allocation scheme for hydrogen-electric hybrid UAV network transmission;
[0089] In this embodiment, a dynamic power allocation model for hydrogen-electric hybrid UAV network transmission is established, including:
[0090] According to the network transmission dynamic power allocation requirements of hydrogen-electric hybrid drones, historical data of hydrogen-electric hybrid drones, including the historical distribution of network transmission dynamic power, is collected. The collected historical data of hydrogen-electric hybrid drones is divided to determine the training set and test set;
[0091] Based on machine learning technology, a training set is used to train the machine learning model, so that the machine learning model can autonomously learn the network transmission dynamic power allocation behavior of the hydrogen-electric hybrid UAV, and determine the network transmission dynamic power allocation model of the hydrogen-electric hybrid UAV based on machine learning;
[0092] Based on the cross-validation method, a test set was used to test the dynamic power allocation model for network transmission of hydrogen-electric hybrid UAVs based on machine learning. The model was evaluated to see whether it can effectively allocate the dynamic power of network transmission of hydrogen-electric hybrid UAVs, and the model test evaluation results were determined.
[0093] According to the model test evaluation results, the parameters of the hydrogen-electric hybrid UAV network transmission dynamic power allocation model based on machine learning are adjusted, and the machine learning-based hydrogen-electric hybrid UAV network transmission dynamic power allocation model after parameter adjustment is continuously optimized to determine the optimal hydrogen-electric hybrid UAV network transmission dynamic power allocation model.
[0094] In this embodiment, the analysis of the hydrogen-electric hybrid drone status monitoring characteristic data includes:
[0095] Obtain the optimal dynamic power allocation model for hydrogen-electric hybrid UAV network transmission, and deploy the optimal dynamic power allocation model in the actual hydrogen-electric hybrid UAV network transmission dynamic power allocation environment;
[0096] The state monitoring characteristic data of the hydrogen-electric hybrid UAV is input into the optimal hydrogen-electric hybrid UAV network transmission dynamic power allocation model. According to the optimal hydrogen-electric hybrid UAV network transmission dynamic power allocation model, the state monitoring characteristic data of the hydrogen-electric hybrid UAV is analyzed, and the network transmission dynamic power of the hydrogen-electric hybrid UAV is allocated to determine the hydrogen-electric hybrid UAV network transmission dynamic power allocation plan.
[0097] According to the dynamic power allocation scheme for network transmission of hydrogen-electric hybrid UAVs, the network transmission dynamic power of hydrogen-electric hybrid UAVs is adjusted and allocated to optimize energy utilization and communication performance.
[0098] In this embodiment, the network transmission dynamic power of the hydrogen-electric hybrid UAV is adjusted and allocated, including:
[0099] The output power of hydrogen fuel cells and lithium batteries, as well as the transmission power of network transmission and communication modules, are adjusted according to the dynamic power allocation scheme for hydrogen-electric hybrid UAV network transmission. Based on mission priority, power for critical tasks and communications is allocated first to optimize energy utilization and communication performance.
[0100] Among them, according to energy priority, when the lithium battery has sufficient power, it will be used first to supply power, reducing the load of the hydrogen fuel cell; when the lithium battery is insufficient, the output power of the hydrogen fuel cell will be increased, and the lithium battery will be charged at the same time;
[0101] Among them, according to the communication priority, when the network load is high or the signal strength is weak, the transmission power of the communication module is increased to ensure the communication quality; when the network load is low or the signal strength is strong, the transmission power of the communication module is reduced to save energy.
[0102] Specifically, by dynamically adjusting power distribution, energy utilization efficiency is maximized, the flight time of hydrogen-electric hybrid drones is extended, and the stable operation of the communication module is ensured in different network environments.
[0103] Specifically, when the lithium battery is low on power, the output power of the hydrogen fuel cell is increased, including:
[0104] When the lithium battery is low on power, the remaining power ratio SOC of the lithium battery corresponding to the moment when the lithium battery is low on power is retrieved, with a range of 0-1;
[0105] Retrieve the adjustment amplitude ratio of the transmission power of the network transmission communication module;
[0106] Wherein, when the adjustment amplitude ratio of the transmission power of the network transmission communication module is positive, it indicates that the transmission power of the network transmission communication module increases; when the adjustment amplitude ratio of the transmission power of the network transmission communication module is negative, it indicates that the transmission power of the network transmission communication module decreases;
[0107] Get the average value of the percentage gradient of power consumption when using lithium battery power supply;
[0108] Obtaining a power regulation coefficient using the adjustment amplitude ratio of the transmission power of the network transmission communication module and the gradient average value of the power consumption percentage;
[0109] Get the current total load power;
[0110] The output power of the hydrogen fuel cell is increased by combining the current total load power with the power regulation coefficient.
[0111] The technical effect of the above-mentioned technical solution is that when the lithium battery charge is low, it can dynamically adjust the output power of the hydrogen fuel cell to ensure a continuous and stable supply of system energy. This avoids system downtime or performance degradation caused by lithium battery depletion. By accessing the lithium battery's remaining charge (SOC), the solution accurately understands the current state of the lithium battery and makes appropriate adjustments accordingly. This precise control helps extend the battery life while optimizing overall energy efficiency. The above-mentioned technical solution dynamically adjusts the power of the network transmission communication module based on the transmission power adjustment amplitude ratio. This helps minimize energy consumption while meeting communication needs, especially when the lithium battery charge is low. The gradient average of the power consumption percentage when powered by the lithium battery is used as a factor in determining the power adjustment coefficient. This reflects the system's energy usage over time and helps more intelligently adjust the hydrogen fuel cell output power to suit different workloads and requirements. The above-mentioned technical solution can access the current total load power and combine it with the power adjustment coefficient to increase the hydrogen fuel cell output power. This ensures that the system can flexibly adjust energy supply based on actual load conditions, thereby maintaining optimal performance and efficiency. By comprehensively considering the lithium battery status, network transmission power requirements, power consumption percentage, and system load, this solution achieves efficient energy utilization. This helps reduce energy waste and improve overall system energy efficiency. By dynamically adjusting the hydrogen fuel cell's output power when the lithium battery is low, this solution enhances system stability and ensures normal operation under various operating conditions.
[0112] Specifically, the output power of the hydrogen fuel cell is increased by combining the current total load power with the power regulation coefficient, including:
[0113] Retrieve the power regulation coefficient;
[0114] The power adjustment coefficient is obtained by the following formula:
[0115]
[0116] Where R represents the power regulation coefficient; P fIndicates the adjustment ratio of the transmission power of the network transmission communication module; E p Indicates the average value of the percentage gradient of power consumption when powered by lithium batteries;
[0117] Comparing the power adjustment coefficient with a preset coefficient threshold;
[0118] When the power regulation coefficient is lower than a preset coefficient threshold, the output power of the hydrogen fuel cell is increased in proportion to (1-SOC)*α; wherein SOC represents the remaining power ratio of the lithium battery; α represents the power regulation coefficient;
[0119] When the power adjustment coefficient is not lower than a preset coefficient threshold, a preset nonlinear corresponding coefficient is retrieved from a database;
[0120] The nonlinear response coefficient is used to adjust the sensitivity of the output power to insufficient power, and the value range of the nonlinear response coefficient is 1.13-1.25;
[0121] The power adjustment coefficient and the current total load power are combined with a nonlinear corresponding coefficient to set the increase ratio of the output power of the hydrogen fuel cell.
[0122] The increase ratio of the output power of the hydrogen fuel cell is obtained by the following formula:
[0123]
[0124] Wherein, B represents the increase ratio of the output power of the hydrogen fuel cell; P c Indicates the output power of the hydrogen fuel cell in the current non-increased state; P z Indicates the current total load power; R indicates the power regulation coefficient; SOC indicates the remaining power ratio of the lithium battery; v indicates the nonlinear response coefficient.
[0125] The technical solution described above achieves the following: By calculating a power regulation coefficient based on factors such as the transmission power adjustment ratio of the network transmission communication module and the average gradient of the percentage of power consumption when powered by the lithium battery, the hydrogen fuel cell output power is dynamically adjusted. This system can rationally allocate power based on different system states (such as the lithium battery charge level and the power demand of the communication module), improving energy efficiency and avoiding energy waste. When the lithium battery charge is low, different strategies are used to adjust the hydrogen fuel cell output power based on the comparison between the power regulation coefficient and a preset threshold. This hierarchical control approach ensures stable system operation under different operating conditions, avoids system failures caused by sudden power changes, and improves the stability and reliability of the entire energy supply system. By using a nonlinear response coefficient to adjust the output power sensitivity to power shortages, the hydrogen fuel cell can quickly and accurately respond to changes in power demand when the lithium battery charge is low, promptly increasing output power to meet load requirements and improving system responsiveness.
[0126] At the same time, in the above technical solution The power regulation coefficient combines the transmission power adjustment ratio of the network transmission communication module and the average power consumption percentage gradient when powered by lithium batteries. The transmission power adjustment ratio of the network transmission communication module reflects changes in the power demand of the communication module. An increase in the power demand of the communication module may indicate a change in the overall system load, requiring adjustment of the hydrogen fuel cell output power. The average power consumption percentage gradient when powered by lithium batteries reflects the changing trend of power consumption when powered by lithium batteries. A large power consumption gradient indicates rapid lithium battery power depletion, requiring advance planning of hydrogen fuel cell power output. The combined calculation of these two factors is used to measure the degree to which the current system state requires hydrogen fuel cell power regulation.
[0127] This formula comprehensively considers the hydrogen fuel cell output power in its unused state, the current total load power, the power regulation coefficient, the remaining charge percentage of the lithium battery, and the nonlinear response coefficient. By combining these parameters, an appropriate increase ratio for the hydrogen fuel cell output power is calculated to meet the system power demand. When the lithium battery charge is low, the increase ratio calculated using this formula can precisely increase the hydrogen fuel cell output power based on factors such as the actual system load, the current hydrogen fuel cell power, the power regulation coefficient, and the nonlinear response coefficient to meet the load demand and avoid power under- or over-supply. Properly controlling the hydrogen fuel cell output power can reduce excessive discharge of the lithium battery when the charge is low. Excessive discharge accelerates lithium battery aging. By appropriately increasing the hydrogen fuel cell power, the depth of discharge (DOD) of the lithium battery can be reduced, extending its service life and reducing battery replacement costs. Effectively increasing the hydrogen fuel cell output power when the lithium battery charge is low ensures continuous and stable system operation, improves the overall energy system's endurance, and meets the needs of long-term equipment operation. This is particularly suitable for applications with high endurance requirements, such as mobile power banks and electric vehicles.
[0128] Furthermore, the solution dynamically adjusts the output power of the hydrogen fuel cell based on the current total load power and the power regulation coefficient. This dynamic response mechanism ensures that the system can rapidly adjust energy supply in response to varying load demands, thereby maintaining system stability and performance. By introducing the power regulation coefficient, the solution enables more precise control of the hydrogen fuel cell's output power. This precise regulation helps reduce energy waste and improve energy efficiency. Furthermore, power adjustment based on the remaining charge (SOC) of the lithium battery further ensures the rational allocation and use of energy. When the power regulation coefficient is at least a preset threshold, the solution uses a nonlinear response coefficient to adjust the sensitivity of the output power to battery power shortages. This nonlinear regulation mechanism enables more flexible adjustment of the hydrogen fuel cell's output power in response to low lithium battery power, thereby maintaining system stability and performance. Furthermore, the range of the nonlinear response coefficient (1.13-1.25) ensures appropriate and rational regulation. By using parameters such as the preset coefficient threshold and the nonlinear response coefficient, the solution achieves intelligent and automated power regulation. This intelligent regulation mechanism reduces the need for manual intervention and improves system reliability and stability. Parameters in this solution, such as the power regulation coefficient and nonlinear response coefficient, can be adjusted and optimized based on actual needs. This scalability and flexibility enable the solution to adapt to diverse application scenarios and load requirements. By comprehensively considering factors such as the current total load power, the power regulation coefficient, the remaining charge percentage of the lithium battery, and the nonlinear response coefficient, the solution optimizes the output power of the hydrogen fuel cell, thereby improving the overall performance and energy efficiency of the system.
