Background technique

With the increasing shortage of conventional energy in the world and a series of environmental problems caused by the use of fossil energy, countries around the world have increased their attention and investment in the use of renewable energy. Governments have included the development of new renewable energy on the agenda. And it is equipped with relevant policy support, including solar power generation, wind power generation, wave power generation, biomass power generation, etc.

Among them, the wave energy is proportional to the wave period, the square of the wave height, and the width of the wave-facing surface. In the ocean energy, the wave energy is the most unstable one, and it has random variability on the time scale.
