Power Smoothing Control in a Grid-Connected Marine Current Turbine System for Compensating Swell Effect [PDF]

open access: yes, 2013
Variations of marine current speed may lead to strong fluctuations in the power extracted by a marine current turbine (MCT). During short-time period, swell effect is the main cause for the current speed variations.
