Abstract

Ocean energy heavily depends on environmental conditions, making extracting maximum power more complex and challenging. A novel adaptable reactive control is proposed for a linear wave generator. Based on the theory, the maximum output power is extracted when the excitation force and wave speed are in resonance. However, the phase between excitation force and velocity depends on the wave period, where it keeps changing. In this paper, the intrinsic impedance of the linear machine is analyzed at every wave period. Since the maximum power can be regulated at the electrical terminal using power electronic devices, the electrical impedance can counteract the phase difference between the excitation force and the velocity. The novel maximum power tracking algorithm is proposed based on the estimated phase difference between voltage and current. The benefit of the proposed method is that the additional configuration is not required, and more power can be extracted.
