Control, forecasting and optimisation for wave energy conversion

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 ...

Wave Energy Resource Analysis for Use in Wave Energy Conversion

In order to correctly predict and evaluate the response of wave energy converters (WECs), an accurate representation of wave climate resource is crucial. This paper gives an overview of wave resource modeling techniques and applies a methodology to estimate the naturally available and technically recoverable resource in a given deployment site. The methodology was initially developed by the Ele...

Energy Consumption Forecasting and Optimisation for Tool Machines

Soaring energy prices, signs of a human-made climate change and legislative pressure have brought the energy consumption of machines to the attention of machine tool builders and their customers. To enable manufacturers and operators of machines to include energy consumption into their considerations in an objective way, we introduce an efficient method to model the energy consumption behaviour...

Forecasting Requirements in the Optimal Control of Wave Energy Converters

Fundamental formulae for wave-energy conversion

The time-average wave power that is absorbed from an incident wave by means of a wave-energy conversion (WEC) unit, or by an array of WEC units-i.e. oscillating immersed bodies and/or oscillating water columns (OWCs)-may be mathematically expressed in terms of the WEC units' complex oscillation amplitudes, or in terms of the generated outgoing (diffracted plus radiated) waves, or alternatively,...
