Future large-scale implementation of wave energy converts (WECs) will introduce an anthropogenic activity in the ocean which may contribute to underwater noise. The Ocean houses several marine species with acoustic sensibility; consequently the potential impact of the underwater noise needs to be addressed. At present, there are no acoustic impact studies based on acquired data. The WEAM projec...

A self tuning PID control strategy using reinforcement learning is proposed in this paper to deal with the control of wind energy conversion systems (WECS). Actor-Critic learning is used to tune PID parameters in an adaptive way by taking advantage of the model-free and on-line learning properties of reinforcement learning effectively. In order to reduce the demand of storage space and to impro...

With the change in the wind profile, the speed of doubly fed induction generator (DFIG) of wind energy conversion system (WECS) changes from super synchronous to sub synchronous range and vice versa. DFIG is operated to generate quality power; hence, power at rotor side is controlled using matrix converter taking power from grid and feeding back power to the grid depending on the wind profile. ...

Abstract This paper provides a systematic analysis of the large scale PMSG (permanent magnet synchronous generator)-based WECS (wind energy conversion system) torsional vibration problem under MPPT (maximum power point tracking) control and constant control. is from perspective SSO (sub-synchronous oscillation), SSH harmonics) forced vibration. The cause negative total system damping, weakened ...

To achieve cost parity with other renewables, the wave energy sector requires significant reduction. Increasing wind turbine scale is one successful route to reduction in industry. This paper aims at investigating scalability of converters (WECs) and providing a thorough review analysis published data. Unlike turbines for which absorbed increases diameter, WECs complicated varies by WEC type. H...

This work presents a modular floating structure, which consists of five inner tension-leg platforms and two outermost wave energy converters (denoted as MTLPW).

This paper investigates a novel single stage AC–AC power conversion, as an alternative to multistage AC– DC–AC power conversion topology, for interfacing the wind energy conversion system (WECS) to a grid as a distributed load system. A comprehensive dynamic model of proposed AC–AC converter is developed to satisfy all the functions of the converter. A new time switching pattern and a control m...

Future nearshore wave energy converter (WEC) arrays will influence coastal and sediment dynamics, yet there are limited numerical methodologies to quantify their possible impacts. A novel coupled WEC-Wave method was developed these influences on the climate. The power performance of an Oscillating Surge Wave Energy Converter (OSWEC) array simulated dissipation due array. OSWEC’s effect local cl...

Biomimetics and creatures could contribute to novel design inspiration for wave energy converters, as we have seen numerous examples in applications of other branches engineering. However, the issue how obtain valuable biological entities, or bionic cases, that produce designs, may be challenging designers converters (WECs).
