Multi-Frequency Proportional-Resonant Control for Wave Power Generation System

Article Preview

Abstract:

A grid voltage vector oriented proportional resonant (PR) control strategy is applied to the grid current control of the float-type wave power generation system. Compared with the conventional double closed-loop proportional integral (PI) control method, the proposed multi-frequency PR control method can realize zero steady-state error in AC input signal in the stationary frame, without complex coordinate rotation transformation and decoupling control. The overall wave power generation system model is built with Matlab/Simulink to evaluate the performance of the PR control method. Simulation results have shown that the PR control can well improve the robustness and the power quality of the float-type wave energy conversion control system.
