Abstract

In order to solve the problem of output power pulsation of multiple hydraulic generators in hydraulic storage wave energy converter under autonomous control mode, a method of average power for transferring wave energy based on an active power compensation is proposed. According to the characteristics and working principle of the power generation system of the wave energy converter, an active power compensation device is attached to the AC side of the grid-connected inverter, which can simultaneously suppress the power pulsation of multiple hydraulic generator sets and transfer the average power to the grid. A simulation model for power pulsation suppression of grid-connected hydraulic generator sets is established to verify the effectiveness of this method. The simulation results show that the grid-connected power of the wave energy converter changes gently attached the power compensation, and the power pulsation caused during the starting or stopping of multiple hydraulic generator sets can be completely absorbed. The method of average power transferring can improve the adaptability of the high-power wave energy converter in the island micro-grid and other situations.
