To date, one of the main challenges in wave energy field is to achieve energy-maximizing control order reduce levelized cost (LCOE). This paper presents a model predictive velocity tracking method based on hierarchical structure for Wavestar-like deivce WEC-SIM benchmark. The first part system aims estimate excitation moment (WEM) by using Kalman filter. Then, an extended filter (EKF) chosen ob...

We elucidate the effect of non-extracting reflectors on performance wave energy converter (WEC) arrays. consider an infinitely periodic row converters parallel to discrete axisymmetric (C-R arrays), and we study how spatial configuration affects extraction. Using a multiple-scattering algorithm for linear wave-array interactions, conduct series simulations C-R arrays range parameters, wavenumbe...

In this research article we have proposed a new hybrid bridge resonant DC-DC converter with analog MPPT controller for the photo voltaic system in stand-alone load. The output of the photo voltaic panel is unregulated DC supply due to the change in weather conditions. The maximum power is tracked with respect to the temperature and irradiance level by using DC-DC converter. The logic truth tabl...

The Galway Bay wave energy test site promises to be a vital resource for wave energy researchers and developers. As part of the development of this site, a floating power system is being developed to provide power and data acquisition capabilities, including its function as a local grid connection, allowing for the connection of up to three wave energy converter devices. This work shows results...

This paper addresses the Archimedes Wave Swing (an offshore wave energy converter, which produces electricity from sea waves). It compares the performances of latching control (a discrete, highly non-linear, intrinsically sub-optimum control strategy), of reactive control, of phase and amplitude control (two optimum control strategies that involve non-causal transfer functions, which have to be...

This paper describes the behaviour of a flap-type oscillating wave energy converter near a straight coast. The mathematical formulation is based on a linear potential flow model. Application of Green’s theorem to a semi-infinite fluid domain yields a hypersingular integral equation for the velocity potential which is solved using a series expansion of Chebyshev polynomials. Extremes in the hydr...

In this paper a wave-to-wire approach to model the exploitation of ocean energy by point absorbers in heave is presented. Attention is focused on the impact that the control strategy of the Wave Energy Converter (WEC) has both on the power performance of the single device and on the grid power quality at the connection point, when point absorbers are arranged in wave farms. Two different contro...
