Накратко на български

Системите за вълнова енергия се анализират, за да се разбере как параметричният резонанс при люлеенето им може да увеличи производството на ток. Това помага за намаляване на разходите по електроенергията и улеснява прехода към въглеродно неутрално общество.

Control parametric resonance of wave energy conversion systems

This Marie Skłodowska Curie Action (MSCA) project, entitled “Control parametric resonance of wave energy conversion systems (CONPARA)”, looks at how parametric resonance occurs in pitch and roll modes of wave energy converters (WECs), and how WECs make use of parametric resonance to improve its performance. The research questions are: (1) how to model parametric resonance in an accurate and efficient manner, (2) how to qualify the energy transfer form one degree of freedom (DoF) to another, and (3) how to set on or set off the occurrence of parametric resonance. Those topics are important because parametric resonance has been frequently observed in WECs as an unexpected nonlinear phenomenon. Not only is there widespread lack of understanding the nonlinear dynamics and energy transfer mechanism caused by parametric resonance, but open questions also have been identified in modelling, detecting, predicting and control of parametric resonance. Among various renewable energy resources, wave energy has a great potential in providing a low-carbon energy society, (1) to fulfil the Sustainable Development Goal (SDG) of affordable and clean energy defined by the United Nations (UN), and (2) to achieve the EU 2030 Climate & Energy Framework objectives. Currently, WEC technology has not been commercially applied, mainly due to its high levelised cost of energy (LCoE). However, the LCoE can be reduced significantly by the novel control system developed in this project, via designs of (1) WECs to exploit parametric resonance, and (2) multi-DoF control and power take-off (PTO) systems. With a significantly reduction in LCoE, commercial operation of WEC farms can directly contribute to UN’s Carbon Neutral goal in 2050. The project objectives are dedicated to: (1) identifying a high-fidelity and computation-efficient model to represent WEC parametric resonance, (2) developing novel power take-off mechanism and corresponding control methods to improve WEC efficiency by utilising parametric resonance, (c) prototyping a scaled down WEC rig for tank testing. A parallel goal of this MSCA project is to foster the career development of the individual fellow from an early year researcher to an independent investigator.

Цел на проекта

To date, no marine system, let alone wave energy device, has attempted to exploit parametric resonance as an assistive phenomenon. A number of wave energy researchers have observed the phenomenon and sought to dampen it, but the concept of harnessing the power transferred from (typically) heave to (typically) pitch/roll has not been considered. This fellowship aims to control the parametric resonance of WEC dynamics to improve energy conversion efficiency, based on a 1/20 scale prototype. The research objectives (ROs) are: RO1: Identify a high-fidelity and computation-effective model to represent the WEC parametric resonance with CFD verification in OpenFOAM (open source) and parametric analysis in MATLAB. RO2: Develop advanced nonlinear control strategies and corresponding PTO mechanism for actuation, to improve WEC efficiency making use of its multi-DoF motion and parametric resonance. RO3: Conduct tank testing to verify the modelling of parametric resonance (RO1), and model-based control design and implementation (RO2), based on a self-assembled 1/20 scale prototype. Successful achievement of this fellowship will lead to timely and useful contribution to the wave energy and relevant communities, including: (i) an hydrodynamic model describing WEC parametric resonance with real time computation capacity, (ii) advancing the understanding in WEC parametric resonance, (iii) a 1/20 scale WEC prototype, and (iv) implementable control and PTO systems for multi-DoF WEC systems. In the long term, the successful achievement of this project will improve the technology readiness level (TRL) of wave energy from 5 to 7 for commercial application.
