Description

Technical Field

[0001] This disclosure relates to the field of energy storage technology, and more specifically, to a power regulation method, device, medium, and electronic equipment. Background Technology

[0002] Currently, hydrogen energy plays a crucial role in energy development. However, hydrogen is difficult to store or transport on a large scale, typically requiring compression or liquefaction, which affects the efficiency of hydrogen energy utilization. Ammonia has a higher energy density than compressed or liquefied hydrogen, so converting hydrogen into ammonia can reduce storage and transportation costs and facilitate hydrogen utilization.

[0003] However, the intermittent, random, and volatile nature of green electricity production currently contradicts the goals of traditional chemical engineering, such as safety, stability, long cycle, full load, and optimized operating costs. Furthermore, the synergy between green electricity hydrogen production systems and green hydrogen ammonia production systems is low, resulting in low production efficiency for green hydrogen ammonia production and persistent difficulties in hydrogen consumption.

[0049] In related technologies, hydrogen is difficult to store or transport on a large scale, usually requiring compression or liquefaction, which affects the efficiency of hydrogen energy utilization. Ammonia has a higher energy density than compressed or liquefied hydrogen, so converting hydrogen into ammonia can reduce storage and transportation costs and facilitate hydrogen utilization. However, current green electricity production, due to its intermittent, random, and volatile characteristics, contradicts the goals of safety, stability, long cycle time, full load, and optimized operating costs required by traditional chemical industries. Furthermore, the synergy between green electricity-to-hydrogen and green hydrogen-to-ammonia systems is low, resulting in low production efficiency for green hydrogen-to-ammonia production, and the problem of hydrogen utilization remains.

This method can obtain the output power of the generator set, the state of charge of the energy storage device, and the hydrogen storage capacity of the hydrogen storage device in a green electricity-to-hydrogen-to-ammonia synthesis system. Based on the output power, state of charge, and hydrogen storage capacity, it determines the system's power regulation strategy to adjust the operating power of each device in the system. This improves the coordination between devices in the green electricity-to-hydrogen-to-ammonia synthesis system, reduces the intermittency, randomness, and volatility of green electricity production, achieves safe, stable, and optimized system operation, and improves the production efficiency of green hydrogen-to-ammonia synthesis, thereby realizing hydrogen utilization.

[0051] The present disclosure will now be described in conjunction with specific embodiments.

[0052] Figure 1 This is a flowchart illustrating a power regulation method according to an exemplary embodiment, such as... Figure 1 As shown, this power regulation method can be applied to a green electricity-to-hydrogen ammonia synthesis system, which may include: a generator set, energy storage equipment, and a hydrogen storage device.

[0054] In step S12, the state of charge of the energy storage device is obtained.

[0055] The energy storage device may include an electrochemical energy storage device, which may include a battery body and a PCS (Power Conversion System). The energy storage device can use its own state of charge to control the converter to charge and discharge based on a control strategy, so as to obtain the power fluctuations of the power generation equipment and the power load in the system in real time.

[0056] In step S13, the hydrogen storage capacity of the hydrogen storage device is obtained.

[0057] The hydrogen storage module may include a compressor, a hydrogen storage tank and corresponding pipelines. The hydrogen storage capacity may include the storage capacity of hydrogen gas or liquid hydrogen, and this disclosure does not limit it.

[0058] In step S14, the power regulation strategy of the green electricity hydrogen production and ammonia synthesis system is determined based on the state of charge, the output power, and the hydrogen storage capacity.

[0059] The power regulation strategy is used to adjust the operating power of each device in the green electricity hydrogen production and ammonia synthesis system.

[0060] Using the above method, it is possible to obtain the output power of the generator set, the state of charge of the energy storage device, and the hydrogen storage capacity of the hydrogen storage unit in the green electricity-to-hydrogen-to-ammonia synthesis system. Based on the output power, state of charge, and hydrogen storage capacity, a power regulation strategy can be determined to adjust the operating power of each device in the system. This improves the coordination between devices in the green electricity-to-hydrogen-to-ammonia synthesis system, reduces the intermittency, randomness, and volatility of green electricity production, achieves safe, stable, and optimized system operation, and increases the production efficiency of green hydrogen-to-ammonia synthesis, thereby realizing hydrogen utilization.

[0061] In some embodiments, the green electricity hydrogen production and ammonia synthesis system may further include: a hydrogen production unit and an ammonia production unit; the power regulation strategy may include a power regulation strategy for the generator set, the energy storage device, the hydrogen storage device, the hydrogen production unit, and the ammonia production unit.

[0062] The hydrogen production unit may include an alkaline water electrolysis hydrogen production unit or a proton exchange membrane water electrolysis hydrogen production unit; this disclosure does not limit the specific type. The ammonia production unit may include a synthesis tower, a compressor, and a catalyst loading device. The power regulation strategy may include a power regulation strategy for the generator set, the energy storage device, the hydrogen storage device, the hydrogen production unit, and the ammonia production unit.

[0063] In some embodiments, step S14 above may include: S141. Based on the state of charge, determine the target operating conditions of the green electricity hydrogen production and ammonia synthesis system.

[0064] In one possible implementation, the first operating condition can be used as the target operating condition if the state of charge is greater than or equal to a first preset state of charge threshold; or, if the state of charge is less than the first preset state of charge threshold but greater than a second preset state of charge threshold, the second operating condition can be used as the target operating condition; or, if the state of charge is less than or equal to the second preset state of charge threshold but greater than a third preset state of charge threshold, the third operating condition can be used as the target operating condition; or, if the state of charge is less than or equal to the third preset state of charge threshold but greater than a fourth preset state of charge threshold, the fourth operating condition can be used as the target operating condition; or, if the state of charge is less than or equal to the fourth preset state of charge threshold, the fifth operating condition can be used as the target operating condition.

[0065] The first operating condition is used to characterize that the energy storage device is in standby mode, and the hydrogen production unit, the ammonia production unit, and the hydrogen storage unit are in operation mode; the second operating condition is used to characterize that the energy storage device is in charge / discharge mode, and the hydrogen production unit, the ammonia production unit, and the hydrogen storage unit are in operation mode; the third operating condition is used to characterize that the energy storage device is in charge / discharge mode, the hydrogen production unit and the ammonia production unit are in operation mode, and the hydrogen storage unit is in hot standby mode; the fourth operating condition is used to characterize that the energy storage device is in charge / discharge mode, the hydrogen storage unit and the hydrogen production unit are in operation mode, and the ammonia production unit is in hot standby mode; the fifth operating condition is used to characterize that the energy storage device is in charging mode, and the hydrogen storage unit, the hydrogen production unit, and the ammonia production unit are in hot standby mode.

[0066] For example, the first preset state of charge threshold SoC1 is the switching threshold between the standby state and the operating state of the energy storage device. It can be obtained through experimental measurement. For example, SoC1 = 0.8. When the state of charge SoC is greater than or equal to SoC1, the target operating condition is determined as the first operating condition. In this condition, the energy storage device is in standby state, and the hydrogen production unit, ammonia production unit, and hydrogen storage unit operate at their rated power. At the same time, the generator set limits its output power. The second preset state of charge threshold SoC2 is the switching threshold between the hot standby state and the operating state of the hydrogen storage device. It can be obtained through experimental measurement. For example, SoC2 = 0.6. When the state of charge SoC is less than SoC1 and greater than SoC2, the target operating condition is determined as the second operating condition. In this condition, the energy storage device is in a charging and discharging state, and the hydrogen production unit, ammonia production unit, and hydrogen storage unit operate at reduced power. At the same time, the output power of the generator set is controlled by the MPPT (Maximum Power Point Tracking) control system. The third preset state of charge threshold, SoC3, is the switching threshold between the hot standby state and the operating state of the ammonia production unit. It can be obtained through experimental measurement. For example, SoC3 = 0.4, meaning that in this state of charge, SoC can be less than or equal to SoC2. If the SoC value is greater than SoC3, the target operating condition is determined as the third operating condition. In this condition, the energy storage device is in a charging / discharging state, the hydrogen production and ammonia production units operate at reduced power, the hydrogen storage device is in hot standby mode, and the generator output power is controlled by the MPPT control system. The fourth preset state-of-charge threshold SoC4 is the switching threshold between the hot standby and operating states of the hydrogen production and ammonia production units. It can be obtained through experimental determination. For example, if SoC4 = 0.2, the target operating condition can be determined as the fourth operating condition if the SoC value is less than or equal to SoC3 and greater than SoC4. In this condition, the energy storage device is in a charging / discharging state, the hydrogen production and storage units operate at reduced power, the ammonia production unit is in hot standby mode, and the generator output power is controlled by the MPPT control system. If the SoC value is less than or equal to SoC4, the target operating condition can be determined as the fifth operating condition. In this condition, the energy storage device is in a charging state, the hydrogen production, storage, and ammonia production units are all in hot standby mode, and the generator output power is controlled by the MPPT control system. In this way, the operating conditions of the green electricity hydrogen production and ammonia synthesis system can be determined based on the state of charge of the energy storage equipment, so as to determine the power regulation strategy of the system according to the operating conditions, improve the coordination between the equipment in the system, and achieve safe, stable and optimized operation of the system.

[0067] S142. Determine the power regulation strategy based on the target operating conditions, the output power, and the hydrogen storage capacity.
