Control strategies for oscillating water column wave energy converters
The oscillating water column wave energy converter (OWCWEC) is an established device which produces electricity by causing an ocean wave to drive air through a turbine. A system to control the operation can improve the device’s performance. In varying sea conditions, different objectives for control may be appropriate. For example, in some seas the controller might shut off the plant because th...
متن کاملMaximizing Output Power in Oscillating Water Column Wave Power Plants: An Optimization Based MPPT Algorithm
Abstract: This paper proposes an optimization based maximum power point tracking (MPPT) algorithm for selection of appropriate external rotor resistances of wound rotor induction generator (WRIG). The generator coupled with a Wells turbine is used in oscillating water column (OWC) wave power plants. The Wells turbine suffers with stalling behaviour that reduces the average output power signific...
متن کاملControl of Oscillating Water Column (owc) Wave Energy Plants
Wave energy composes a direct and easy way of harnessing power from the Ocean. Among the different techniques used, OWC devices stand as one of the most promising ones. NEREIDA MOWC demonstration project is a breakwater wave plant located in the Basque location of Mutriku, using Wells turbines and Doubly Fed Induction Generators (DFIGs). Since one of the main objectives when dealing with renewa...
متن کاملPeak-power control of a grid-integrated oscillating water column wave energy converter
A critical characteristic of most WECs (wave energy converters) is the large peak-to-average power ratio. This poses many challenges to the design of high-efficient PTO (power take-off) systems and, even more importantly, to integrate this form of renewable energy into power grids. The OWC (oscillating water column) WECs are devices whose PTO uses an air turbine as the primary energy converter....
متن کاملPneumatic Performance of a Non-axisymmetric Floating Oscillating Water Column Wave Energy Conversion Device in Random Waves
A stochastic approach is used to gain a sophisticated understanding of a nonaxisymmetric floating oscillating water column’s response to random waves. A linear, frequencydomain performance model that links the oscillating structure to air-pressure fluctuations with a Wells Turbine in 3-dimensions is used to study the device performance at a northern California deployment location. Both short-te...
