The strategic vision outlined in the EU Energy Road Map suggests that, by the year 2050, the use of ocean wave energy could fulfill up to 15% of the European Union's energy demands, while allowing a substantial reduction in carbon dioxide emissions, estimated at 136 million metric tons per megawatt-hour. The Spanish Renewable Energies Plan echoes this vision, placing a particular emphasis on the role of wave energy within Spain's energy portfolio. In this milieu, Oscillating Water Column (OWC) converters are emerging as a leading technology for the conversion of wave energy, able to operate from both terrestrial and marine platforms. This study introduces a detailed analytical model for the wave capture chamber of a static OWC wave energy generator, which has been specifically developed and parameterized for the Mutriku Marine Offshore Wave Power Plant (Mutriku's MOWC), located on the coastline of the Basque Country in Spain. The validation of the proposed model is conducted through the utilization of in-situ measured wave input data, alongside the experimental power output data procured from the operational plant. This dual-faceted validation approach ensures the robustness and applicability of the model in real-world scenarios.

This article covers research into cost reduction pathways for wave energy. The primary focus is the development and test of reliable and controllable power take-off (PTO) technology for oscillating water column converters (OWC). This is highly relevant to the ocean energy challenge. Extensive testing via data of the NEREIDA MOWC demonstration project, a breakwater wave plant located in the Basque location of Mutriku, using Wells turbines and Doubly Fed Induction (DFIG) generators is proposed to advance wave energy converter (WEC) devices. The control tests involve the integration of the PTO technology within a new variable controller for OWC wave power generation plants. Due to the nature of the control law, it allows monitoring faults caused by parametrical errors or system disturbances. The reliability tests by means of analysing the electrical signals have been conceived as conditioning monitoring, detection of mechanical faults and hardware damaging also fulfil a secondary aim for the reduction of maintenance cost and unscheduled downtime during operation of OWC plants.

The Spanish Renewable Energies Plan (SREP) for 2011-2020 and the European Energy Road Map are promoting the use of renewable sources as the best way to avoid the undesired global warming, and in particular, the use of Ocean Energy. Within the different types of on-shore wave-based ocean energy devices, Oscillating Water Column (OWC) converters are one of the widely used ones. An OWC device is basically composed by a capture chamber with a turbo-generator module attached to it. This paper presents the modeling and simulation of OWC on-shore wave power plants. The results are particularised for the case of the Mutriku's power plant and then validated by means of experimental data.

This paper deals with the state-space modelling of the Ultra-Low Iota Super Elongated Stellarator of the UPV/EHU, using a physical lumped parameter equivalent circuit approach. The model obtained is validated by means of experimental output data showing an excellent matching with the real system. In order to test the proposed model, a MPC scheme is been successfully implemented both in simulation and experimentally using a real-time control platform, providing also a benchmarking with traditionally used PID controllers.

control of the plasma inductance is an essential tool for the successful operation of Tokamaks in order to overcome stability issues as well as the new challenges specific to advanced scenarios operation. Thus, tokamak operation may benefit from model predictive control techniques to extend the pulse duration by reducing instabilities while guaranteeing tokamak integrity. The numerical results seem to indicate that internal inductance and current profiles can be adequately controlled which will influence the L-H transition timing, the density peaking and pedestal pressure. In this regard, the need for optimal, robust control emerges as a key factor in the development of a nuclear fusion reactor.
