Description

Technical Field

[0001] This invention relates to the field of distributed power generation in power system distribution networks, and in particular to a dual-source combined power supply operation control method applicable to hydrogen-powered emergency power supply vehicles. Background Technology

[0002] In the field of emergency power supply in power systems, the demand for emergency power supply in scenarios such as major natural disasters, temporary power line failures or equipment maintenance, as well as power supply for special scenarios such as important meetings and community livelihood needs, is becoming increasingly stringent. Traditional emergency power supply mainly relies on diesel generators, but they have significant drawbacks such as carbon emissions, exhaust pollution, and high noise levels, making them unsuitable for power supply scenarios with high environmental standards. The environmental friendliness and sustainability of emergency power supply urgently need to be improved.

[0003] Hydrogen energy, as a clean and pollution-free new energy source, has become an important development direction in the field of emergency power supply. Hydrogen fuel cell-based emergency power supply vehicles are gradually replacing traditional diesel generator vehicles in application. Although existing hydrogen emergency power supply vehicles have achieved zero-carbon emission power supply requirements, they generally adopt a single-source power supply mode with on-board hydrogen power. The hydrogen power system in the vehicle chassis is only used for driving and is independent of the on-board power supply system without a coordinated control mechanism. This results in low efficiency of hydrogen energy resource utilization, and the power generation capacity of the chassis hydrogen system is not effectively utilized. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dual-source combined supply operation control method suitable for hydrogen energy emergency power supply vehicles, which can improve the efficiency of hydrogen energy resource utilization while enhancing the power and duration of emergency power supply.

[0005] The technical solution adopted by this invention to solve its technical problem is: to provide a dual-source combined power supply operation control method suitable for hydrogen energy emergency power supply vehicles, including:

[0006] The load-side power is detected, and it is determined whether the load-side power exceeds the rated power of the on-board hydrogen energy power system.

[0007] When the load-side power exceeds the rated power of the on-board hydrogen energy power system, the system enters the first operating condition.

[0008] When the load-side power does not exceed the rated power of the on-board hydrogen energy power system, the system enters the second operating condition.

[0009] In the first operating condition, the on-board hydrogen power supply system and the hydrogen power system are started to jointly supply power to the load side. The on-board hydrogen power supply system continuously supplies power according to the rated power, and the hydrogen power system outputs power through DC / DC control.

[0010] In the second operating condition, the on-board hydrogen power system is activated to provide separate power to the load side.

[0011] In the first operating condition, the load-side power is acquired in real time, and it is determined whether the load-side power is less than the rated power of the vehicle-mounted hydrogen energy power system. When the load-side power is less than the rated power of the vehicle-mounted hydrogen energy power system, the system enters the second operating condition.

When the load-side power is greater than the rated power of the vehicle-mounted hydrogen energy power system, the system enters the first operating condition.

[0014] In the second operating condition, it is determined whether the state of charge of the vehicle-mounted hydrogen power system is less than a threshold. When the state of charge of the vehicle-mounted hydrogen power system is less than the threshold, the hydrogen power system is started to supplement the power supply, and the ratio of the output power of the vehicle-mounted hydrogen power system to the output power of the hydrogen power system is 3:1.

[0015] In the first or second operating condition, it is determined whether the state of charge of the on-board hydrogen power supply system is less than the lower limit and whether the state of charge of the hydrogen power system is less than the threshold. When the state of charge of the on-board hydrogen power supply system is less than the lower limit or the state of charge of the hydrogen power system is less than the threshold, both the on-board hydrogen power supply system and the hydrogen power system stop supplying power.

[0016] The technical solution adopted by this invention to solve its technical problem is: to provide a dual-source combined power supply operation control device suitable for hydrogen energy emergency power supply vehicles, comprising:

[0019] The second execution module is used to execute the second operating condition when the load-side power does not exceed the rated power of the on-board hydrogen energy power system.

[0020] In the first operating condition, the on-board hydrogen power supply system and the hydrogen power system are started to jointly supply power to the load side. The on-board hydrogen power supply system continuously supplies power according to the rated power, and the hydrogen power system outputs power through DC / DC control.

[0021] In the second operating condition, the on-board hydrogen power system is activated to provide separate power to the load side.

[0022] The aforementioned dual-source combined operation control device for hydrogen energy emergency power supply vehicles further includes: a first real-time judgment entry module, used to acquire the load-side power of the load side in real time during the first operating condition, determine whether the load-side power is less than the rated power of the vehicle-mounted hydrogen energy power system, and enter the second operating condition when the load-side power is less than the rated power of the vehicle-mounted hydrogen energy power system.

[0023] In the first operating condition, the output power of the hydrogen power system is the difference between the load-side power and the rated power of the on-board hydrogen power supply system.

[0024] The dual-source combined operation control device for hydrogen energy emergency power supply vehicles further includes: a second real-time judgment entry module, used to acquire the load-side power of the load side in real time during the second operating condition, determine whether the load-side power is greater than the rated power of the vehicle-mounted hydrogen energy power system, and enter the first operating condition when the load-side power is greater than the rated power of the vehicle-mounted hydrogen energy power system.

[0025] The dual-source combined operation control device for hydrogen energy emergency power supply vehicles further includes: a state of charge judgment and replenishment module, used to determine whether the state of charge of the on-board hydrogen energy power system is less than a threshold in the second working condition, and to start the hydrogen energy power system to replenish power supply when the state of charge of the on-board hydrogen energy power system is less than the threshold, and the ratio of the output power of the on-board hydrogen energy power system to the output power of the hydrogen energy power system is 3:1.

[0026] The dual-source combined operation control device for hydrogen energy emergency power supply vehicles further includes: a charge state judgment and shutdown module, used to determine whether the charge state of the on-board hydrogen energy power system is less than a lower limit value and whether the charge state of the hydrogen energy power system is less than a threshold value in the first working condition or the second working condition, and to control both the on-board hydrogen energy power system and the hydrogen energy power system to stop supplying power when the charge state of the on-board hydrogen energy power system is less than the lower limit value or the charge state of the hydrogen energy power system is less than the threshold value.

[0027] The technical solution adopted by the present invention to solve its technical problem is: to provide an electronic device, including a memory, a processor, and a computer program stored in the memory and capable of running on the processor, wherein when the processor executes the computer program, it implements the steps of the above-mentioned dual-source combined power supply operation control method applicable to hydrogen energy emergency power supply vehicles.

[0029] Beneficial effects

[0030] By adopting the above-mentioned technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0031] This invention effectively improves the power supply capacity and hydrogen energy utilization efficiency of the emergency power supply vehicle by coordinating the onboard hydrogen power system and the hydrogen power system under different operating conditions. In the first operating condition, the dual-source power supply breaks through the power limit of a single source in the onboard hydrogen power system, meeting the emergency power supply needs of high-power loads. In the second operating condition, single-source power supply is used, and the hydrogen power system can be flexibly dispatched to supplement power according to actual needs, rationally allocating the output ratio of the two sources and effectively extending the power supply duration.

[0032] This invention breaks down the barrier of two independent hydrogen energy systems, integrating the hydrogen energy power system for driving into the power supply system, realizing the full utilization of hydrogen energy resources in driving and power supply, avoiding energy waste, and the system can automatically switch operating conditions and dynamically adjust output according to load power, greatly improving the adaptability of the power supply vehicle to different emergency power supply scenarios, and taking into account the efficiency and flexibility of power supply.

[0033] Figure 1 This is a system topology diagram of the hydrogen-powered emergency power supply vehicle according to the first embodiment of the present invention;

[0034] Figure 2 This is a flowchart of the first embodiment of the present invention, applicable to the dual-source combined power supply operation control method for hydrogen energy emergency power supply vehicles. Detailed Implementation

[0035] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0036] The first embodiment of the present invention relates to a dual-source combined power supply operation control method suitable for hydrogen-powered emergency power supply vehicles, wherein the hydrogen-powered emergency power supply vehicle is as follows: Figure 1 As shown, the system includes a 300kW onboard hydrogen power supply system (i.e., the superstructure system) and a 100kW vehicle-mounted hydrogen power system (i.e., the chassis system). Both hydrogen power supply systems consist of hydrogen tanks, fuel cells, and lithium battery packs. The onboard hydrogen power supply system converts DC power to AC power output via an inverter, which can be used directly to power loads or connected to a 380V low-voltage power grid. The DC bus of the superstructure system and the DC bus of the chassis system are connected by a 100kW bidirectional DC / DC converter, which is used to manage the output of the chassis system when the two systems are supplying power together.

[0037] like Figure 2 As shown, the dual-source combined power supply operation control method applicable to hydrogen-powered emergency power supply vehicles in this embodiment includes the following steps:

[0038] Step 1: Detect the load-side power and determine whether the load-side power exceeds the rated power of the on-board hydrogen energy power system;

[0039] Step 2: When the load-side power exceeds the rated power of the on-board hydrogen power supply system, i.e., when the load-side power exceeds 300kW, the system enters the first operating condition. In the first operating condition, the on-board hydrogen power supply system and the hydrogen power system are started to jointly supply power to the load side. The on-board hydrogen power supply system continuously supplies power at its rated power of 300kW, while the hydrogen power system outputs power through DC / DC control, and its output power is the difference between the load-side power and the rated power of the on-board hydrogen power supply system.

[0040] In the first operating condition, the load-side power is acquired in real time, and it is determined whether the load-side power is less than the rated power of the on-board hydrogen power supply system. If the load-side power is less than the rated power of the on-board hydrogen power supply system, the system enters the second operating condition. Simultaneously, in the first operating condition, the state of charge (SOC) of both the on-board hydrogen power supply system and the hydrogen power system is also detected. It is determined whether the SOC of the on-board hydrogen power supply system is less than a lower limit, and whether the SOC of the hydrogen power system is less than a threshold. If the SOC of the on-board hydrogen power supply system is less than the lower limit or the SOC of the hydrogen power system is less than the threshold, both the on-board hydrogen power supply system and the hydrogen power system stop supplying power.

[0041] Step 3: When the load-side power does not exceed the rated power of the on-board hydrogen power supply system, the system enters the second operating condition. In the second operating condition, the on-board hydrogen power supply system is activated to provide separate power to the load side.

[0042] In the second operating condition, the load-side power is acquired in real time, and it is determined whether the load-side power is greater than the rated power of the on-board hydrogen power supply system. If the load-side power is greater than the rated power of the on-board hydrogen power supply system, the system enters the first operating condition. Simultaneously, in the second operating condition, the state of charge (SOC) of both the on-board hydrogen power supply system and the hydrogen power system is also monitored. When the SOC of the on-board hydrogen power supply system is less than a threshold, the hydrogen power system is activated to supplement power supply, ensuring that the ratio of the output power of the on-board hydrogen power supply system to the output power of the hydrogen power system is 3:1. When the SOC of the on-board hydrogen power supply system is less than a lower limit or the SOC of the hydrogen power system is less than a threshold, both the on-board hydrogen power supply system and the hydrogen power system cease supplying power.

[0043] The present invention will be further illustrated by a specific embodiment below.

[0044] This embodiment takes a dual-source combined power system consisting of a 300kW vehicle-mounted hydrogen power system and a 100kW hydrogen power system as an example. The threshold for the state of charge is set to 30%, and the lower limit for the state of charge is set to 5%. The specific execution is as follows:

[0045] The system detects the load-side power. When the detected load-side power is 350kW, it enters the first operating condition. At this time, the on-board hydrogen power supply system and the hydrogen power system are started simultaneously. The on-board hydrogen power supply system supplies power at a rated power of 300kW, and the hydrogen power system outputs 50kW power through a bidirectional DC / DC converter to jointly meet the 350kW load demand. When the load-side power drops to 280kW, it automatically switches to the second operating condition, shutting off the power supply of the hydrogen power system. The on-board hydrogen power supply system supplies power independently. At the same time, the state of charge of the on-board hydrogen power supply system and the hydrogen power system is detected. When the state of charge of the on-board hydrogen power supply system drops to 28%, the hydrogen power system is started to supplement the output. At this time, the output of the hydrogen power system is 70kW, and the output of the on-board hydrogen power supply system is 210kW, which are supplied together in a 1:3 ratio. If the load-side power rises to 320kW, it immediately switches back to the first operating condition.

[0046] Under any operating condition, if the state of charge of the on-board hydrogen power system is less than 5% or the state of charge of the hydrogen power system is less than 30%, the power supply of the on-board hydrogen power system and the hydrogen power system will be stopped immediately, while hydrogen resources will be reserved to ensure the vehicle can travel back.

[0047] It is easy to see that the method of this implementation breaks the independent operation mode of the hydrogen power system and the vehicle-mounted hydrogen power supply system, incorporating the hydrogen power system used for vehicle driving into the emergency power supply system, and realizing the joint operation of the two hydrogen energy systems. The output of the two hydrogen energy systems can be flexibly dispatched according to the load conditions, so that the hydrogen power system can not only meet the driving power demand, but also supplement the emergency power supply. This ensures that hydrogen energy resources are fully utilized throughout the driving and power supply process, greatly improving the overall utilization efficiency of hydrogen energy and avoiding the energy waste caused by the operation of a single system. This implementation divides different operating conditions according to the load power. For high-power load scenarios, the two sources start simultaneously for joint power supply, breaking through the power limit of single source power supply and achieving a doubling of power supply capacity to meet the emergency power supply needs of high-load scenarios. For medium and small power load scenarios with low state of charge, the chassis hydrogen energy system is started as a supplementary output, and the output ratio of the two sources is reasonably allocated, effectively extending the emergency power supply duration. The dynamic dispatch of the two sources allows the power supply capacity to be automatically adjusted according to the load size, greatly improving the power supply adaptability of the hydrogen energy supply vehicle.
