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.
Ocean wave energy has de potential to satisfy 15% of EU energy demand, cutting 136 MT/MWh off the CO2 emissions by 2050, as stated by the EU Energy Road Map. Analogously, the Spanish Renewable Energies Plan specifical...

Ocean wave energy has de potential to satisfy 15% of EU energy demand, cutting 136 MT/MWh off the CO2 emissions by 2050, as stated by the EU Energy Road Map. Analogously, the Spanish Renewable Energies Plan specifically highlighted the Spanish marine energy potential with special emphasis in wave energy. In this context, Oscillating Water Column (OWC) converters are maybe nowadays the most promising wave energy converters, with the potential capability of sea energy harnessing from diverse on-shore and floating structures. This paper presents an analytic modeling of the wave capture chamber for a fixed on-shore OWC wave power plant. The model is particularized and parameterized for the case of the Mutriku MOWC wave power plant, located in the Spanish Basque Country coast, and then validated using both measured real wave entry data and experimental generated output power from the plant
Fusion power may be seen as the energy of the future in the sense that it composes a potentially clean, cheap and unlimited power source that would reduce the worldwide dependency on non-renewable energies. Neverthele...

The European Energy Road Map 2050 and the Spanish Renewable Energies Plan for 2011-2020 are promoting the use of renewable energies as a necessary path to achieve the greenhouse gas reduction target necessary to avoid the rising global warming, and in particular, the use of Ocean Energy. Within the different types of on-shore wave-based energy devices, Oscillating Water Column (OWC) converters are one of the more widely used ones. An OWC plant is basically composed by a capture chamber coupled to a turbo-generator module. This paper deals with the model implementation of on-shore OWC wave energy power devices. The model is parameterised and validated for the particular case of Nereida MOWC wave power system using ad-hoc real data from Mutriku's power plant.

Climate change is challenging the current worldwide model of power generation. In this sense, European Union is promoting a deep transition collected in the 20-20-20 targets and the 2050 Energy Roadmap. These adjectives must be achieved by developing the use of clean, carbon-free energies, as it is the case of the renewableenergies and in particular of the ocean energy. The main problem with these kinds of energies is to reach a commercially mature stage so they can compete with conventional power sources. Therefore, it is crucial to reduce generation costs and increase the efficiency of the existing devices. With this regard, thework presents the modelling and experimental validation of the capture chamber of an Oscillating Water Column (OWC)-based powerplant. Although the study of the turbine and the generator may be considered a quite well-known matter, the control-oriented modelling of the capture chamber still deserves a further study to improve the power generation. In this work, a model obtained analytically of the OWC chamber is developed and numerically implemented. The model proposed is also validated and affords excellent results.

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.

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.
