“…First of all, the SEM‐REV test site presents a relatively mild wave climate compared to other sites in the world. Its annual average power is indeed equal to 12 kW/m only while the Portuguese pilot zone reaches 32 kW/m, and Belmullet in Ireland shows an average wave power of nearly 70 kW/m [24, 25]. However, in the absence of data from these other sites, the SEM‐REV was retained as a worst‐case scenario from a wave climate perspective.…”

Dynamic rating is an approach which implies to operate an electrical network closer to its thermal limits. This approach may be very beneficial for wave farms, as they are expected to present a highly fluctuating electrical current profile while benefiting from the large thermal inertia of the soil where their export cable will be buried. However, as the implementation of this approach is still in its infancy for offshore wind farms, it may be expected that the first wave farms, under the form of small-scale test sites, will be sized with respect to electrical current limits at a first stage. This sizing may be upgraded at a second stage when design methods will have included dynamic rating. However, this raises the question of the economic feasibility of this two-step approach, which is studied in this paper. Also, performing such a techno-economic analysis requires developing an electrothermal model of the export cable able to represent its transient response in a sufficiently precise manner while requiring also a reasonable computing time. In this perspective, a comparative analysis between several electrothermal modelling methods is also described in this paper.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

The lack of technological innovation in the utilization of ocean wave energy as a renewable energy source is caused by a lack of public knowledge about this matter. Therefore, it needs to be introduced early, especially to pre-service teachers through innovative and fun learning. The aim of this study was to identify the responses of pre-service physics teachers about the learning program to introduce the concept of utilizing ocean wave energy. The research subjects were 31 sixth semester students who are taking environmental physics lectures in the physics education study program at one of the teachers' university in West Nusa Tenggara Province for the 2019/2020 academic year. The sample was taken by using purposive sampling technique. Data collection was carried out by means of observation, interview, and questionnaire techniques. All data collected were then analyzed simultaneously descriptively. The findings of this study showed that almost 90% pre-service physics teacher students agreed that the learning program had a positive impact on increasing interest, motivation, critical thinking skills, and creative thinking skills, and made them easier to solve problems and grow solid cooperation. Therefore, it can be concluded that pre-service physics teacher students agree to the use of semi-assisted project-based learning programs with contextual problems.

“…It is also interesting to note that the SEM-REV test site presents mild energy levels, compared to other locations where the average wave power is three to five times more important [2]. The SEM-REV test site presents indeed an annual average power of 12kW/m while the Portuguese pilot zone reaches 32 kW/m [2], and Belmullet in Ireland shows an average wave power of nearly 70 kW/m [22]. This increased level of available energy may render the proposed approach economically viable, even with small-scale farms.…”

Due to the ever-increasing electricity demand, along with the need to reduce the dependence on fossil or nuclear resources, a growing amount of renewable energy is integrated in the energy mix of many countries. However, the cost-effective integration of wave energy remains difficult as its cost is still not competitive compared with other energy sources. This paper deals with the energy production management of a simulated wave energy converter farm based on point absorbers that could be installed in the vicinity of the SEM-REV site. The approach considers the electrothermal behaviour of the export cable in combination with techno-economic aspects. The method can be used to extend the power export capability of a test site at no cost, which could be very interesting to install more marine renewable energy (MRE) converters and/or of greater rated power. Our study shows that exploiting the thermal inertia of a wave farm submarine export cable, while also considering techno-economic aspects, may lead to an increase of 18% in the annual energy production without modifying this cable.
