The invention discloses a double-layer optimization method and device for a one-base multi-body type wave energy power generation device, and the method comprises the steps of setting the environmental parameters of a sea according to the sea condition of a target region, and calculating the time sequence of an incident wave according to the environmental parameters of the sea and a wave energy spectrum corresponding to the target region; according to the time sequence and the geometrical parameters of the floater in each wave energy absorber in the target area, obtaining the hydrodynamic coefficient of the floater in each wave energy absorber through calculation by means of the potential flow theory and the wave theory; obtaining the maximum value of the time average value of the total generated power of all the wave energy absorbers in the target area through calculation by means of the hydrodynamic coefficient and the motion equation; and optimizing the geometric parameters of the floaters by adopting an optimization algorithm and taking the maximum value of the time average value of the total power generation power as an evaluation index to obtain the optimal geometric parameter of each floater when the time average value of the total power generation power is globally maximum. The embodiment of the invention can effectively improve the total capacity of the wave power generation device.
Description
technical field [0001] The invention relates to the technical field of wave power generation, in particular to a double-layer optimization method and device for a multi-body wave power generation device. Background technique [0002] Ocean wave energy is a clean, renewable energy source that has a higher energy density than solar and wind energy. In addition, the system efficiency of wave energy generating devices can reach more than 50%, which is much higher than that of wind energy and solar energy devices. The efficiency and reliability of the oscillating buoy wave energy generation technology have been confirmed by pool experiments and real sea experiments. Its working principle is: the buoy of the primary capture system moves under the action of waves, thereby converting wave energy into kinetic energy and potential energy of the buoy , the energy conversion system (also known as the power intake system) converts mechanical energy into electrical energy. This type of ...
