Abstract

This paper addresses the integration of a point absorber type wave energy converter into power grids, a process complicated by wave energy's intermittent and unpredictable nature. It proposes a sliding mode control strategy with an exponential reaching law in a voltage-oriented control architecture for the grid-side converter of the point absorber. The control objective is to maximize the transfer of generated power to the electrical grid, while concurrently stabilizing the DC bus voltage at a predetermined value and achieving a unity power factor. Results from simulations conducted within a MATLAB framework underscore the efficacy of the sliding mode control approach in sustaining specified DC bus voltage values, and in regulating the direct and quadrature currents by minimizing their respective tracking errors.
