This embodiment can be applied to the situation of collecting and converting energy from the marine environment taking into account multiple energy sources such as wave energy, solar energy and wind energy, and can be applied to the integrated ocean energy power generation system.

Figure 1 As shown, the control method specifically includes the following steps:

[0043] S11. Obtain current environmental parameters in real time.

[0044] S12. According to the current environmental parameters, with the goal of maximizing the comprehensive power generation efficiency of the wave power generation module, the solar power generation module and the wind power generation module, the angle between the spine and the wave direction is adjusted.

[0045] Specifically, the integrated ocean energy power generation system can be improved based on the existing Waveline Magnet power generation device. In the wave energy power generation module, the floating plate can float on the sea surface due to buoyancy and can move up and down with the waves. One end of the lever arm is connected to the floating plate and can move under the drive of the floating plate. The other end can be connected to the spine. The spine can specifically include a piston pump and a turbine generator. The lever arm can drive the piston pump to reciprocate to form an internal high pressure. The pressure can drive the turbine generator to rotate and generate electricity, thereby realizing the efficient conversion of wave energy. Multiple floating plates can be arranged on both sides of the spine. Under the influence of waves, the extension direction of the spine is horizontal or nearly horizontal. When working, the spine and the wave direction can be at a certain angle. The angle between the spine and the wave direction can affect the wave energy capture efficiency. Among them, the floating plate can be made of lightweight and high-strength materials to reduce underwater resistance and increase response speed. The lever arm can be connected to the spine through precision bearings to ensure the stability and durability of movement. For the solar power generation module, a photovoltaic panel can be set on the surface above each floating plate to receive sunlight. Among them, the photovoltaic panel can be a high-efficiency solar cell. For the wind power generation module, a wind turbine generator can be installed on the spine body to generate electricity using the wind on the sea surface. The wind turbine generator can adopt a low wind speed start design to adapt to the variable wind speed conditions on the sea surface, and the wind turbine generator can be installed at an appropriate position on the spine body to maximize the wind capture efficiency.

[0046] Based on the above-mentioned ocean energy integrated power generation system, an intelligent algorithm can be developed to adjust the power generation strategy and energy distribution according to real-time data, so as to optimize the system performance and improve the energy conversion efficiency. Specifically, the current environmental parameters can be obtained in real time, which may include various environmental parameters that will affect the power generation efficiency of the power generation system, such as meteorological parameters, wave parameters, etc. Correspondingly, detection equipment, such as various sensors, can be installed in the power generation system to monitor various environmental parameters in real time. Every time the current environmental parameters are obtained, the angle between the spine and the wave direction can be adjusted in real time according to the current environmental parameters and with the goal of maximizing the comprehensive power generation efficiency of the wave power generation module, the solar power generation module and the wind power generation module. Specifically, a power generation efficiency management and optimization algorithm model can be established based on the comprehensive power generation efficiency, and the current environmental parameters can be substituted into it, and then the angle between the spine and the wave direction that needs to be adjusted can be determined according to the power generation efficiency optimization target, so as to realize the maximum utilization of energy and the optimization of power generation efficiency through the model combined with environmental factors, so as to realize the intelligent management and control of the power generation system.

[0047] Wherein, optionally, the comprehensive power generation efficiency is:

[0048] E total =α·E wind +β·E wave +γ·E solar ;

[0049] Among them, E wind Indicates wind power generation efficiency, E wave Indicates the wave energy generation efficiency, E solar represents the solar power generation efficiency, α represents the wind power generation weight, β represents the wave power generation weight, and γ represents the solar power generation weight. That is, the algorithm model of comprehensive power generation efficiency can be the weighted sum of wind power generation efficiency, wave power generation efficiency, and solar power generation efficiency. Each weight can be experimentally calibrated and adjusted according to the specific system and environment.

[0050] Further optionally, the current environmental parameters include: wind speed, wave height, wave period and light intensity; the wind power generation efficiency, the wave power generation efficiency and the solar power generation efficiency are respectively:

Specifically, the algorithm model of the above comprehensive power generation efficiency can be further refined, where the wind power generation efficiency is proportional to the cube of the wind speed, the wave power generation efficiency is proportional to the square of the wave height, the wave period, and the cosine value of the angle between the spine and the wave direction, and the solar power generation efficiency is proportional to the light intensity and the photovoltaic panel area. Each of the power generation coefficients can also be experimentally calibrated and adjusted according to the specific system and environment.

[0055] Further optionally, the current environmental parameters also include ambient temperature; before adjusting the angle between the spine and the wave direction based on the current environmental parameters with the goal of maximizing the comprehensive power generation efficiency of the wave power generation module, the solar power generation module and the wind power generation module, it also includes: obtaining current weather forecast data; determining an environmental adaptability adjustment coefficient based on the current environmental parameters, the current weather forecast data and historical environmental parameters; adjusting the comprehensive power generation efficiency based on the environmental adaptability adjustment coefficient; the adjusted comprehensive power generation efficiency is:

[0056] E final =E total ·A env ;

[0057] Among them, A env Represents the environmental adaptability adjustment coefficient. Specifically, the current weather forecast data is the weather forecast data for the future relative to the current moment, such as wind speed, precipitation probability, etc. The historical environmental parameters are the current environmental parameters obtained at each moment in history, and specifically, the average value of parameters such as wind speed and wave height within a certain period of history can be used for backup. The current weather forecast data and historical environmental parameters can be used for trend analysis and prediction, so as to further adjust the power generation strategy. The algorithm model of the environmental adaptability adjustment coefficient can be specifically A env =f(T a ,W f ,H d ), where T a Represents the ambient temperature, which may affect the performance of photovoltaic panels and wind turbine generators, W fIndicates the current weather forecast data, H d represents the historical environmental parameters, which can be the data after the above average processing, that is, the environmental adaptability adjustment coefficient can be determined according to the function composed of the current environmental parameters, the current weather forecast data and the historical environmental parameters. The specific function form can be optimized according to the historical data to ensure accuracy. Further, the algorithm model of the above comprehensive power generation efficiency can be adjusted according to the environmental adaptability adjustment coefficient to obtain the comprehensive power generation efficiency after considering the environmental adaptability, that is, E total ·A env Based on the adjusted algorithm model of comprehensive power generation efficiency, the model can be used to predict and optimize power generation efficiency according to current environmental parameters, such as wind, waves, light and other conditions, as well as current weather forecast data and historical environmental parameters, so as to achieve optimal energy output. Among them, the real-time data monitoring and the response speed of the system are the key to realizing the optimization potential of the model.

[0058] On the basis of the above technical solution, optionally, the lever arm is a telescopic rod, and the current environmental parameter includes the wave height; the control method further comprises: adjusting the length of the lever arm in real time according to the current environmental parameter. Specifically, the lever arm can realize the telescopic function through a linear motor or a hydraulic rod, and the wave energy conversion efficiency can be optimized by adjusting the length of the lever arm. Specifically, the length of the lever arm can be dynamically adjusted according to the wave height data obtained by real-time monitoring to achieve the best energy conversion efficiency and reduce energy loss under different wave conditions. At the same time, the telescopic rod can provide more design flexibility, allowing the system to adapt to different marine environments.

Specifically, the length of the lever arm can also be adjusted according to the average wave height data in a preset historical period, thereby reducing the real-time requirements and ensuring that energy can be effectively converted in most cases. Exemplarily, the maximum length of the lever arm can be set to 1.5 times the average wave height.

[0060] On the basis of the above technical solution, optionally, the control method further comprises: dynamically adjusting the angle of the photovoltaic panel in real time by following the waves through a stabilizing module to keep the photovoltaic panel horizontal. The stabilizing module may be a hydraulic device, a pneumatic device or a pan / tilt device, etc. By keeping the photovoltaic panel horizontal, it can be ensured that the photovoltaic panel can better receive sunlight.

[0061] On the basis of the above technical solution, optionally, the control method further includes: centrally managing the electric energy generated by the wave power generation module, the solar power generation module and the wind power generation module, and using it for seawater electrolysis and storing it in the form of hydrogen energy. Specifically, since the storage of electric energy itself is relatively difficult, the electric energy generated by the three methods can be uniformly managed and dispatched, and used for seawater electrolysis to convert seawater into hydrogen, and the obtained hydrogen can be stored in a special hydrogen storage tank, thereby forming a hydrogen energy reserve, realizing efficient conversion and storage of energy, and further improving energy utilization efficiency.

[0062] Further optionally, the control method also includes: obtaining the property parameters of the seawater to be electrolyzed; according to the property parameters, adjusting the electrolysis temperature and / or the electrolysis voltage with the goal of maximizing the hydrogen energy conversion efficiency of seawater electrolysis. Specifically, corresponding detection equipment, such as various sensors, can be installed to monitor the property parameters of the seawater to be electrolyzed in real time, wherein the seawater to be electrolyzed can be obtained from the ocean at any time and placed in the electrolyzer. Then, a corresponding algorithm model can be constructed based on the hydrogen energy conversion efficiency of seawater electrolysis (between 0-1, 1 represents the highest efficiency), and the property parameters of the seawater to be electrolyzed are substituted, and then the electrolysis temperature and / or electrolysis voltage to be adjusted are determined according to the conversion efficiency optimization target, so that the model is combined with the chemical and physical properties of seawater and the electrolysis operating conditions to optimize the efficiency and output of the electrolysis process to achieve efficient conversion and storage of hydrogen energy.

[0063] Further optionally, the attribute parameters include: purity, corrosivity and salinity; the seawater electrolysis hydrogen energy conversion efficiency is:

[0064]

[0065] Among them, k elec Represents the electrolysis efficiency coefficient, S p Indicates the purity, C r Indicates the corrosiveness, S a represents the salinity, T seawater represents the electrolysis temperature, V elecRepresents the electrolysis voltage. Specifically, purity (between 0-1, 1 represents the purest), corrosivity (between 0-1, 1 represents the most corrosive) and salinity (unit ppt, parts per thousand) jointly affect the electrolysis efficiency. High purity, low corrosivity and appropriate salinity are conducive to improving the electrolysis efficiency. The electrolysis temperature is the temperature of the seawater to be electrolyzed (unit Celsius), which is converted to Kelvin temperature by adding 273.15 to consider the effect of temperature on the electrolysis reaction rate. Usually, an increase in electrolysis temperature can increase the reaction rate, but it may also bring the risk of increased corrosivity. Optionally, the electrolysis temperature can be adjusted by electric heating. The electrolysis voltage is the voltage applied during the electrolysis process (unit volt), which can directly affect the energy input during the electrolysis process. The higher the electrolysis voltage, the greater the energy input, but it may also cause more energy loss and side reactions. The electrolysis efficiency coefficient can be experimentally calibrated and adjusted according to the specific electrolysis operating conditions and seawater properties.
