Description

Technical Field

[0001] The present invention relates to the technical field of operation and maintenance of an offshore water hydrogen production platform, and in particular to an electric power control system for an offshore water electrolysis hydrogen production platform. Background Art

[0002] The technology of hydrogen production by water electrolysis is based on the future carbon neutrality or even negative carbon. The technology is relatively mature and has high hopes from all walks of life. The equipment for water electrolysis, the electrolyzer, is very suitable for the centralized production of hydrogen due to its modular characteristics. At the same time, PEM hydrogen production is particularly suitable for use in conjunction with renewable energy such as photovoltaics and wind power. As the cost of renewable energy, especially solar and wind power, decreases, the international community is paying more and more attention to the production of hydrogen by water electrolysis using renewable energy.

[0003] The equipment power and energy consumption control of the water hydrogen production platform is one of the key technologies. The water hydrogen production platform usually adopts water electrolysis hydrogen production technology, and its equipment power and energy consumption directly affect the efficiency and cost of hydrogen production. Efficient water hydrogen production equipment should have high dynamic response, high safety and reliability, and reduce energy consumption by optimizing control strategies.

[0004] Specifically, the power and energy consumption control of water hydrogen production equipment involves the following aspects: Dynamic response capability: The dynamic response capability of the equipment refers to the ability of the equipment to quickly adjust its output to ensure the stability of process parameters under input fluctuations and load start and stop conditions. A high dynamic response rate helps to improve the stability and efficiency of the hydrogen production system. Wide load adjustment and adaptability to frequent start and stop: Water hydrogen production equipment needs to be adjusted within a wide load range and be able to adapt to frequent start and stop operations. This capability ensures the stable operation of the equipment under different working conditions. Hot standby and hot start functions: The hot standby and hot start functions of the equipment reduce startup time and energy consumption, thereby improving the overall efficiency of the equipment.

[0005] The energy consumption of the water electrolysis process is very large, generally accounting for a large proportion of the total energy consumption of the unit, and is also the biggest obstacle to the cost of green hydrogen. Therefore, it is of great significance to find ways to reduce the energy consumption of water electrolysis to produce hydrogen. Summary of the invention

[0023] The environmental information collection and storage device is connected to the power control device, collects and stores current wind force and humidity information, and then sends the current wind force and humidity information and the stored historical wind force and humidity information to the power control device.

[0024] The wind power generation equipment is connected to the power control equipment, and automatically controls power according to current weather and forecast weather, as well as the needs of water electrolysis to produce hydrogen and energy storage, so as to achieve a balance between power supply and demand and improve power generation efficiency.

[0025] Operating power of wind turbines The power demand level, average wind speed and drive energy consumption should be comprehensively considered to ensure that the system can operate efficiently under different operating conditions.

[0026] ;in, Indicates the maximum output power of wind power generation equipment. Indicates the level of power demand, Represents a constant related to the characteristics of a wind turbine, usually provided by the manufacturer. Indicates ratio A small constant used to limit the maximum output power under medium-level demand. Indicates ratio A smaller constant further limits the maximum output power under low-level requirements.

[0027] In addition to the output power, the driving energy consumption of the wind power generation equipment also needs to be considered. It can be calculated by the following formula: ; represents the coefficient related to the efficiency of wind power generation equipment, Fixed base energy consumption.

[0028] Introduce the weather forecast model and use the following formula to calculate the average wind speed during the forecast period , and adjust the output power of wind power generation equipment accordingly : ; ; in, It is Hourly forecast wind speed, is the number of hours in the forecast period, is the electrical energy demand during the forecast period.

[0029] The water electrolysis hydrogen production equipment is connected to the power control equipment and the communication equipment, obtains the hydrogen transportation demand through the communication equipment, controls the equipment power according to the demand, and then sends the corresponding power demand to the power control equipment according to the equipment power.

[0030] The water electrolysis hydrogen production equipment can predict the hydrogen demand in the future through intelligent algorithms , and adjust its working status in advance accordingly. The formula is as follows: ; in, is the current hydrogen demand, is the predicted future hydrogen demand, is a weighting factor between 0 and 1 that is used to balance current and future hydrogen demand.

[0031] The energy storage charging device is connected to the power control device and the communication unit, and includes an energy storage unit and a charging unit. Each energy storage unit in multiple water electrolysis hydrogen production platforms in a certain area sends its current stored power to the power control device in each other water electrolysis hydrogen production platform through the communication device. In addition, the energy storage unit stores the electric energy sent from the wind power generation equipment after adjustment according to the actual power.

[0032] Energy storage charging equipment can automatically adjust the charging and discharging strategy according to the power supply and demand relationship between platforms to minimize power transmission losses. , the formula is as follows: ; in, and Represent the electrical energy sent and received respectively, is a constant representing the loss rate per unit of electrical energy transmitted.

[0033] The charging unit is arranged on the inner side of the rectangular docking area at the edge of the platform, corresponding to the charging interface at the bow or stern of the operation and maintenance ship, and is coordinated to automatically start charging when the operation and maintenance ship is connected to the charging interface. In addition, the charging unit simultaneously receives the power parameters of the operation and maintenance ship and sends them to the remote monitoring platform through the communication unit for the staff to understand the information and monitor in real time.

[0034] The fixing equipment is arranged in the middle position on both sides of the rectangular docking area, and fixes the corresponding connection unit in the middle of the hull, so that the operation and maintenance ship is in a stable state after docking, ensuring the safety of charging, transporting hydrogen or boarding.

[0035] The communication device is connected to the power control device and the energy storage charging device, receives the hydrogen transportation or charging information of the remote monitoring platform or the operation and maintenance ship through the remote network, and sends the hydrogen transportation information to the power control device of this platform. In addition, the power information of the energy storage unit in this platform is sent to the communication devices of other platforms in the area, and the power information of multiple energy storage units sent by the communication devices of other platforms is received at the same time, so as to complete the interaction between the offshore water hydrogen production platform, the operation and maintenance ship and the remote monitoring platform.

[0036] The power control device is connected to all other devices in the current water hydrogen production platform.

[0037] Its main configuration is: (1) Control the operating power of the water electrolysis hydrogen production equipment on this platform according to the demand for hydrogen transportation, while meeting the demand for hydrogen transportation volume, ensuring the efficient operation of the water hydrogen production equipment and reducing unnecessary waste.

[0038] (2) By analyzing the overall energy storage status of the energy storage units in this area, based on the adaptive energy storage threshold, the energy demand of the energy storage units in this platform is adjusted in a targeted manner to ensure the balance between energy storage and charging and reduce energy loss.

[0039] (3) Based on the power demand corresponding to the operating power of the water electrolysis hydrogen production equipment and the storage power demand of the energy storage unit, combined with the current and future predicted weather changes, the operating power of the wind power generation equipment is controlled to ensure that the power demand is met while reducing equipment and energy consumption and increasing the life of the platform equipment.

[0040] For the above three functions of the power control equipment, the specific control methods are as follows: (1) According to the demand for hydrogen transportation, the operating power of the water electrolysis hydrogen production equipment on this platform is controlled, specifically: The power control device receives the hydrogen transportation information sent by the remote monitoring platform through the communication unit of the platform, extracts the hydrogen transportation amount, and compares it with the hydrogen amount in the current hydrogen storage device. The comparison results are divided into three cases: If the current amount of stored hydrogen is greater than or equal to the amount of hydrogen transported, that is, the transportation requirements are met, the water electrolysis hydrogen production equipment does not need to work and has no electricity demand, waiting for the completion of transportation before hydrogen production and storage.

[0041] If the current amount of stored hydrogen is less than the amount of hydrogen transported, but exceeds 50%, that is, it does not meet the transportation requirements, and the water electrolysis hydrogen production equipment works normally, the required electricity corresponds to the normal range.

[0042] If the current amount of stored hydrogen is less than the amount of hydrogen transported, but less than 50%, it does not meet the transportation requirements, and the water electrolysis hydrogen production equipment needs to work at high power, and the required electrical energy corresponds to a higher range.

[0043] (2) By analyzing the overall energy storage status of the energy storage units in the region, based on the adaptive charging energy storage threshold, the energy demand of the energy storage units in the platform is adjusted in a targeted manner, specifically: The communication unit receives the current charging storage energy of the energy storage units in all water electrolysis hydrogen production platforms in the area (including this platform), and at the same time, receives the number of operation and maintenance ships in the current area.

[0044] First, the energy storage threshold is adaptively adjusted based on the charging demand. That is, if the charging demand is relatively large (the number of operation and maintenance ships exceeds 70% of the number of platforms), the energy storage threshold is adjusted to 80% of the current maximum charging value of the platform; if the charging demand is within the normal range (the number of operation and maintenance ships does not exceed 70% of the number of platforms), the energy storage threshold is adjusted to 50% of the maximum charging value.

[0045] Secondly, the average value of the current energy storage capacity of all energy storage units is calculated and compared with the energy storage threshold. If it is greater than or equal to the energy storage threshold, the energy storage unit of the current platform does not need to continue storing energy; if it is less than, it is determined whether the current energy storage capacity of the energy storage unit of the platform is less than the energy storage threshold. If it is less than, conventional energy input is performed.

[0046] (3) According to the power demand corresponding to the operating power of the water electrolysis hydrogen production equipment and the storage power demand of the energy storage unit, combined with the current and future predicted weather changes, the operating power of the wind power generation equipment is controlled, specifically: First, the electric energy demand is calculated or judged, and the results are divided into three levels: high, medium and low. The high level means that the water electrolysis hydrogen production equipment is in a high power state and the energy storage unit has an energy storage demand; the medium level means that the water electrolysis hydrogen production equipment is in a normal power state and the energy storage unit has an energy storage demand, or the water electrolysis hydrogen production equipment is in a high power state and the energy storage unit has no energy storage demand; the low level means one of the four situations: the water electrolysis hydrogen production equipment is in a normal power state, is not working, or the energy storage unit has or has no energy storage demand.

[0047] Secondly, compare and analyze the current wind speed and humidity with historical data to obtain the average wind speed for a period of time in the future.

[0048] Subsequently, the power demand level is analyzed in combination with the weather conditions to obtain the degree of drive control of the wind power generation equipment.

[0049] For example, if the power demand level is high and the average wind force is high, the wind turbine generator system is controlled by normal driving energy consumption, whereas if the wind force is low, the wind turbine generator system is controlled by higher driving energy consumption.

[0050] If the power demand level is low and the average wind speed is high, the wind turbines are controlled with lower drive energy consumption or no wind turbine control is required.

[0051] The specific working process of the power control system of the present invention is exemplified as follows: Example 1: (1) After the power control device in the current platform receives the hydrogen transportation demand through the communication equipment, it monitors that the current hydrogen reserves are greater than the transportation demand, and the water hydrogen production equipment does not need to work, that is, there is no operating power and required electricity.

[0052] (2) In the area where the current platform is located, the power control device receives a large number of operation and maintenance ships and transport ships that are transporting hydrogen through the communication equipment. For example, if the number exceeds 10, which is greater than 70% of the number of platforms in the area, the energy storage threshold is adaptively adjusted to 80% of the maximum charging value of the platform. At the same time, if the average value of the electric energy storage capacity of all platforms is less than the energy storage threshold, the power control equipment of each platform monitors its current electric energy storage capacity.

[0053] The power control device of the platform whose current electric energy storage capacity is less than the energy storage threshold controls the energy storage unit to perform conventional energy storage work, that is, the operating power and required electric energy are carried out according to the preset values.

[0054] (3) Since only the energy storage unit is performing conventional energy storage work, the current electricity demand is judged to be at a low level. At the same time, if it is monitored that there will be strong wind force at present and in the future, wind power generation is controlled based on lower driving energy consumption, and the subsequent increase in wind force can drive the wind power generation equipment solely by wind force.

[0055] Example 2: (1) After the power control equipment in the current platform receives the hydrogen transportation demand through the communication equipment, it monitors that the current hydrogen reserves are far less than the transportation demand. The water hydrogen production equipment needs to work at high power, that is, the operating power and required electrical energy are large.

[0056] (2) In the area where the current platform is located, if the number of all operation and maintenance ships and transport ships that are transporting hydrogen received by the power control device through the communication device is less than 70% of the number of platforms in the area, the energy storage threshold is adaptively adjusted to 50% of the maximum value of the platform charge. However, if the average value of the energy storage capacity of all platforms is less than the energy storage threshold, the power control device of each platform monitors its current energy storage capacity.

[0057] The power control device of the platform whose current electric energy storage capacity is less than the energy storage threshold controls the energy storage unit to perform conventional energy storage work, that is, the operating power and required electric energy are carried out according to the preset values.

[0058] (3) The water hydrogen production equipment is in a high-power state and the energy storage unit is operating at normal power, which requires a large amount of electricity. Therefore, the current electricity demand is judged to be at a high level. At the same time, wind power generation is directly controlled based on the high driving energy consumption, and the subsequent increase in wind power can appropriately reduce the driving energy consumption to control the wind power generation equipment.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
