Control of Wave Energy Converters for Maximum Power Absorption with Time Domain Analysis

Tuning of fuzzy logic controller using an improved black hole algorithm for maximizing power capture of ocean wave energy converters

Seas and oceans are the most important sources of renewable energy in the world. The main purpose of this paper is to use an appropriate control strategy to improve the performance of point absorbers. In this scheme, considering the high uncertainty in the parameters of the power take-off system in different atmospheric conditions, a new improved black hole algorithm is introduced to tune fuzzy...

Mathematical Framework for Hydromechanical Time- Domain Simulation 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 ...

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...

Balancing Power Output and Structural Fatigue of Wave Energy Converters by Means of Control Strategies

In order to reduce the cost of electricity produced by wave energy converters (WECs), the benefit of selling electricity as well as the investment costs of the structure has to be considered. This paper presents a methodology for assessing the control strategy for a WEC with respect to both energy output and structural fatigue loads. Different active and passive control strategies are implement...
