[0002] Offshore wind power technology uses wind turbines to convert offshore wind energy into electrical energy, which is transmitted to the land through high-voltage transmission lines and incorporated into the power grid or consumed locally through a series of power system equipment. It has the characteristics of sufficient offshore wind energy and being far from the land, with broad development prospects. However, with the expansion of the power generation scale, the volatility of renewable energy has an increasingly significant impact on offshore wind power grid connection, resulting in poor power quality and power supply stability, and causing an impact on the power grid when wind power is connected to the grid.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 , Figure 1 It is a schematic flowchart of a method provided by an embodiment of the present invention. The method of the embodiment of the present invention can be applied to a computer device, and the computer device includes but is not limited to devices such as smart phones, laptop computers, tablet computers, desktop computers, physical servers, and cloud servers. As Figure 1 shown, the method of this embodiment includes steps S101 to S103, which are described in detail as follows:

[0038] Step S101: Obtain the system parameters of the wind power grid-connected hydrogen production system. The system parameters include wind turbine parameters, generator parameters, grid parameters, and electrolyzer parameters. The wind power grid-connected hydrogen production system includes a wind power generation module and a hydrogen production module.

[0039] In this step, as Figure 2 shown, the wind power generation module includes a wind turbine and a permanent magnet synchronous generator, and the hydrogen production module includes an electrolyzer, a heater, and a cooler. The wind power grid-connected hydrogen production system also includes a grid, transmission lines, transformers, and a rectifier and filter module.

[0040] Optionally, in this embodiment, it is considered that the grid side has sufficient capacity to provide the required reactive power compensation. The main function of this module is to determine the grid side voltage level and the rated voltage of each section of the transmission line, and then determine the converter station and transformer parameters on the transmission line. In this model, the grid side voltage level can be taken as 110 KV. The transmission line is transformed to 35 KV through Transformer No. 1 and then to 600 V through Transformer No. 2. This point is taken as the grid connection point of the rectifier module and the generator connection point. At this point, Transformers No. 3 and No. 4 can be used to transform the voltage on the power generation side and the rectification side respectively. For example, Transformer No. 4 is used to step down the voltage to 220 V.

[0041] Optionally, this module converts the alternating current from offshore wind power generation into direct current and supplies it to the electrolyzer. Its main structure consists of a rectifier and a filter. The rectifier mainly adopts a thyristor rectifier circuit controlled by 6-pulse PWM. The input end is connected to the grid connection point of the rectifier module, and the output end is connected to the filter module. The filter mainly adopts an LC filter circuit, and the parameters here can be set to 2 mH and 50 mF.

[0042] Step S102: Use a preset electro-thermal coupling mechanism to generate a hydrogen production control strategy for the wind power grid-connected hydrogen production system according to the system parameters. The hydrogen production control strategy includes a target wind speed condition and a target temperature condition.

[0043] In this step, the use of a preset electro-thermal coupling mechanism to generate a hydrogen production control strategy for the wind power grid-connected hydrogen production system according to the system parameters includes:

[0044] Use a preset electro-thermal coupling mechanism to generate a target temperature condition corresponding to the electrolyzer module according to the electrolyzer parameters;

[0045] Use a preset wind power conversion mechanism to generate the target wind speed condition of the wind power generation module according to the wind turbine parameters, the generator parameters, and the grid parameters;

[0046] Generate a hydrogen production control strategy for the wind power grid-connected hydrogen production system according to the target temperature condition and the target wind speed condition.

[0047] In this embodiment, the electrothermal coupling mechanism includes an electrothermal coupling relationship, and the wind power conversion mechanism includes a conversion relationship between wind energy and electrical energy.

[0048] Optionally, using the preset electrothermal coupling mechanism to generate the target temperature condition corresponding to the electrolyzer module according to the electrolyzer parameters includes:

[0049] Using the electrothermal coupling relationship of the electrolyzer module, based on the electrolyzer parameters, calculate the target temperature condition corresponding to the electrolyzer module when reaching the preset optimal electrolysis performance.

[0050] In this embodiment, the electrolyzer is the core module of the entire model and is the place where electrical energy is converted into hydrogen energy. The main function of the electrolyzer is to absorb excess wind power, reduce the impact of wind power grid connection under wind speed fluctuations, and improve stability. The main parameters of the electrolyzer are voltage, current, and temperature, and the coupling relationship is as follows:

[0051] U cell =E rev +η act.a +η act.c +η ohm ;

[0052]

[0053] E rev.0 | T＝298 . 15K =1.23V;

[0054]

[0055]

[0056] j 0c =1.7A / m 2 ;

[0057] η ohm =IR electrolyzer 。

[0058] In the formula, U cell is the voltage across the electrolyzer, with the unit of V; E rev is the reversible voltage. The electrolytic water hydrogen production reaction is an endothermic reaction and cannot occur spontaneously. An external voltage is required to make it happen, and the minimum voltage required to make it happen is called the reversible voltage; η act.a and η act.c are the anodic and cathodic polarization overvoltages respectively, which represent the energy provided for the electrode reaction charge transfer. The numerical value thereof has a great relationship with the catalyst on the electrode surface; η ohmis the ohmic overvoltage, which characterizes the voltage drop caused by various factors (i.e., the equivalent resistance of the electrolytic cell) that impede the flow of electrons in the electrolytic cell, and its value is proportional to the electrode current; T is the temperature of the electrolytic cell; is the reversible voltage temperature coefficient, which can be taken as 0.24516 mV / K; I is the total current of the electrolytic cell; A is the plate area of the electrolytic cell, with the unit of m 2 ; j 0a and j 0c are the exchange current densities of the anode and cathode respectively; α is the electrode exchange coefficient, which is unified as 0.5 for both the anode and cathode; F is the Faraday constant; R is the molar gas constant; a 0a and b 0a are the electrode exchange current density coefficients, which are 866.4 A / m2 and 375 K respectively; R electrolyzer is the equivalent resistance of the electrolytic cell, which is determined by the properties of the electrolytic cell itself.

[0059] Here, the concentration overvoltage, which characterizes the voltage drop caused by product concentration and mass convection-diffusion, is ignored. In an alkaline electrolytic cell, compared with the polarization overvoltage and the ohmic overvoltage, the value of the concentration overvoltage is relatively small and can be ignored.

[0060] In addition, in order to maintain the temperature of the electrolytic cell module, a cooler and a heater are provided. The electrolytic water hydrogen production reaction is an endothermic reaction, but when the voltage is high, the ohmic overvoltage is large and a large amount of heat will be generated. Therefore, a cooler and a heater are needed, and the power of both can be adjusted according to the temperature.

[0061] Optionally, the generating of the target wind speed condition of the wind power generation module according to the preset wind power conversion mechanism, the fan parameters, the generator parameters, and the grid parameters includes:

[0062] Using the conversion relationship between wind energy and electric energy, calculating the target wind speed condition corresponding to the wind power generation module when reaching the grid rated power according to the fan parameters and the generator parameters.

[0063] In this embodiment, the wind power conversion mechanism includes the conversion of wind energy into mechanical energy by a wind turbine and the conversion of mechanical energy into electric energy by a generator.

[0064] The wind turbine converts wind energy into mechanical energy and transmits it to the generator, and its absorbed power is as follows:

[0065]

[0066] P WT = C p P Air = T m ω w ;

[0067] Where PAir is the wind power output after the sea breeze blows towards the swept area of the wind turbine blade, with the unit of W; P WT is the input power of the wind turbine, that is, the power that absorbs wind energy and converts it into mechanical energy, with the unit of W; ρ is the air density, taking ρ = 1.293 kg / m 3 ; R is the radius of the wind turbine, with the unit of m; v is the current wind speed, with the unit of m / s; T m is the mechanical torque output by the wind turbine, with the unit of N·m; ω w is the radius of the wind turbine; C p is the reduction multiple, that is, the power coefficient, and its maximum value is defined by the Betz limit and cannot exceed 59.3%. The value of C p is related to the pitch angle and the tip speed ratio:

[0068]

[0069]

[0070]

[0071] where λ is the tip speed ratio; β is the pitch angle of the wind turbine, with the unit of radian; each coefficient is determined by the characteristics of the wind turbine itself. Here, c1 = 0.5176, c2 = 116, c3 = -0.4, c4 = -5, c5 = -21, c6 = 0.0068 can be taken.

[0072] This model adopts a direct-drive wind turbine, so there is no gearbox module, and only the drive shaft problem needs to be considered. The drive shaft system model mainly reflects the process of mechanical energy transfer. It is assumed that the wind turbine and the permanent magnet synchronous generator can be equivalent to a mass block, and the blade torsion and the drive shaft torsion are not considered. Therefore, the wind turbine and the generator have the same rotational speed, that is:

[0073] ω w = ω g ;

[0074] where ω g is the rotational speed of the generator. Therefore, the motion equation of the equivalent mass block is shown as follows:

[0075]

[0076] where T e is the electromagnetic torque of the generator, with the unit of N·m; C g is the damping coefficient, which can be simplified to 0 here; J0 is the moment of inertia of the mass block, with the unit of k g ·m 2 .

[0077] The generator converts the mechanical energy transmitted by the wind turbine into electrical energy. The generator can be a permanent magnet synchronous generator:

[0078] ω e = pω g ;

[0079]

[0080]

[0081] T e = 1.5p[(L d - L q )i d i q + i q λ0];

[0082] P e = Txω e = 1.5p 2 [(L d - L q )i d i q + i q λ0]ω g ;

[0083] where ω e is the electrical angular frequency, p is the number of rotor pole pairs of the permanent magnet synchronous generator, L d and L q are the stator d-axis and q-axis inductances of the permanent magnet synchronous generator respectively, i d and i q are the d-axis and q-axis currents of the permanent magnet synchronous generator respectively, u d and u q are the d-axis component and q-axis component of the output voltage of the permanent magnet synchronous generator respectively, R is the stator resistance of the permanent magnet synchronous generator, λ0 is the stator permanent magnet flux linkage. Here it is assumed that the d-axis and q-axis inductances are equal, i.e., L d = L q = L. After simplification, the following formula can be obtained:

[0084]

[0085]

[0086] T e = 1.5pi q λ0;

[0087] P e = T e ω e = 1.5p 2 i q λ0ω g .

[0088] Step S103, based on the hydrogen production control strategy, when the current wind speed meets the target wind speed condition, control the wind power generation module to supply power to the hydrogen production module until the temperature of the electrolyzer in the hydrogen production module meets the target temperature condition, and then start the electrolyzer to produce hydrogen.

[0089] In this step, the initial state of the model is that the offshore wind power is stably connected to the grid under a steady wind speed, and at this time the electrolyzer module is in a shutdown state. When the wind speed is detected to increase, the electrolyzer module is started. During the startup process of the electrolyzer, one of the most important factors is temperature. The efficiency and productivity of the electrolysis process are closely related to temperature. Within the temperature range that the equipment can withstand, temperature is positively correlated with electrolysis efficiency and productivity. And the heating time required for the temperature to rise from room temperature to a working temperature with higher efficiency is relatively long. Therefore, the strategy during the startup process is to preferentially allocate power to the heater to enable the electrolyzer to reach a higher working temperature as soon as possible.

[0090] In some embodiments, the step of based on the hydrogen production control strategy, when the current wind speed meets the target wind speed condition, control the wind power generation module to supply power to the hydrogen production module until the temperature of the electrolyzer in the hydrogen production module meets the target temperature condition, and then start the electrolyzer to produce hydrogen, includes:

[0091] When the current wind speed is greater than the upper threshold of the target wind speed or the current wind speed is less than the lower threshold of the target wind speed, if the temperature of the electrolyzer does not meet the target temperature condition, control the wind power generation module to supply power to the heater in the hydrogen production module to enable the heater to heat the electrolyzer;

[0092] When the temperature of the electrolyzer reaches the target temperature condition, stop supplying power to the heater, start the electrolyzer, and supply power to the electrolyzer to enable the electrolyzer to perform electrolytic hydrogen production.

[0093] Optionally, after the step of when the temperature of the electrolyzer reaches the target temperature condition, stop supplying power to the heater, start the electrolyzer, and supply power to the electrolyzer to enable the electrolyzer to perform electrolytic hydrogen production, further includes:

[0094] Supply power to the cooler in the hydrogen production module to maintain the temperature of the electrolyzer to meet the target temperature condition.

[0095] In this embodiment, when the wind speed is higher than the rated wind speed, the wind power generation exceeds the rated grid-connected power, and the electrolyzer plays a role in absorbing the excess power, using the excess power for the electrolyzer module. At this time, according to the electrolyzer temperature, it is divided into the following two cases: If the electrolyzer temperature is below the set working temperature, no electrolysis voltage is applied, that is, the electrolysis process is not started, and all the power is supplied to the heater to rapidly increase the temperature. If the electrolyzer temperature is above the set working temperature, heating is stopped, and the excess wind power is mainly used for two parts: the electrolysis process and the cooler. The power of the cooler is determined by the heat generated during the electrolysis process, and it can be simply considered to be positively correlated with the square of the current. Its function is to prevent the temperature from exceeding the limit that the equipment can withstand. And the amount of power allocated to the electrolysis process determines the input voltage of the electrolyzer. Through the I-V curve of the electrolyzer, the voltage and current at the current temperature and input power can be calculated, and this voltage is used as a reference value to input the 6-pulse PWM pulse generator of the rectifier to control the output voltage of the rectifier, thereby adjusting the power of the electrolysis process.

[0096] When the wind power is small, the wind power generation is correspondingly small at this time. The wind power non-grid-connected mode can be adopted, and all the wind power is used for the electrolyzer. At this time, the electrolysis process in the electrolyzer device is stopped, and the heater is started, and all the power is used for heating. In this way, the temperature of the electrolyzer can be increased during the period of small wind power, preparing for the subsequent stage and improving the electrolysis efficiency and output of the electrolyzer in the next stage. This process will last for a long time due to the thermal inertia of the device. In case of extreme situations, such as the temperature reaching the set working temperature of the equipment, the heater is turned off, the cooler is turned on, and the electrolysis process is started to electrolyze water to produce hydrogen. The voltage regulation process is the same as in operating state 1.

[0097] In some embodiments, the method further includes:

[0098] Based on the hydrogen production control strategy, if the current wind speed is between the lower threshold and the upper threshold of the target wind speed, control the wind power generation module to output power to the wind power grid connection.

[0099] In this embodiment, when the wind speed is slightly lower than the rated wind speed, the wind power generation is slightly less than the rated grid-connected power at this time. At this time, the cooler, heater, and electrolysis process of the electrolyzer are not started, and the natural heat dissipation state is maintained.
