Wave energy power generation and flywheel energy storage integration system and method thereof

A wave energy generation and flywheel energy storage integration system, comprising:

• a wave energy generation device, which is configured to convert wave energy into electrical energy in a power generation cycle, and supply the electrical energy to a grid;
• a flywheel energy storage device, which is configured to store rotational kinetic energy of a flywheel;
• a flywheel state-of-charge calculation module, which is configured to calculate the rotational kinetic energy of the flywheel to obtain a calculation result;
• and
• an energy management module, which is configured to determine whether the flywheel energy storage device is in a fully charged state and in an energizable state according to the calculation result, when the wave energy generation device is in the power generation cycle, power of the electrical energy does not satisfy grid specification power of the grid and the flywheel energy storage device is in the energizable state, control the flywheel energy storage device to release the rotational kinetic energy of the flywheel for compensating and outputting power, so as to stably supply power to the grid, and when the flywheel energy storage device is not in the energizable state, calculate a loss of power supply probability of the wave energy generation and flywheel energy storage integration system.
