Short-Term Wave Forecasting for Real-Time Control of Wave Energy Converters

Forecasting for Control and Environmental Impacts of Wave Energy Converters

This work is divided in to two distinct parts. In the first part a model is developed to assess the redistribution of wave energy about an offshore array of overtopping type wave energy converters. The model is based on a classical analytical solution for diffraction about a breakwater which is modified to consider an array of dissipating, reflecting and transmitting breakwater segments, which ...

Forecasting Requirements in the Optimal Control of Wave Energy Converters

Real time wave forecasting using neural networks

Forecasting of ocean wave heights, with warning time of a few hours or days, is necessary in planning many operation-related activities in the ocean. Such information is currently derived by numerically solving the differential equation representing wave energy balance. The solution procedure involved is extremely complex and calls for very large amounts of meteorological and oceanographic data...

Real-time wave forecasting using genetic programming

The forecasting of ocean waves on real-time or online basis is necessary while carrying out any operational activity in the ocean. In order to obtain forecasts that are station-specific a time-seriesbased approach like stochastic modeling or artificial neural network was attempted by some investigators in the past. This paper presents an application of a relatively new soft computing tool calle...

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...
