“…In Brazil, the supply chain would consist of companies already operating in the offshore oil and gas sector. This is a very robust sector, which will be able to meet the demands of the ocean [192].…”

“…There are three radial sluice gates with widths of approximately 12.5 m. In the case of a fully open gate, a water height level of 4.5 m is registered for each radial gate. This value is about 3 m for the stop-log gates, which are flat and operate vertically, with widths of 2.85 m. [192].…”

“…As Figure 23a illustrates, the Bacanga basin is 10,219 ha in size, which includes the estuarine body of water and the Bacanga lake. The reservoir capacity is about 40 million cubic meters at an elevation of +4.5 m, corresponding to the spring tide level [192]. As shown in Figure 23b, the dam includes an 800 m embankment rock which is filled with clay material.…”

“…This value is about 3 m for the stop-log gates, which are flat and operate vertically, with widths of 2.85 m. The largest tidal ranges in Brazil are located on the North coast including the coastal areas of Maranhão, Pará, and Amapá. For instance, a tidal energy potential of 22 TWh/year has been estimated for Maranhão state [192]. Some studies have addressed the exploitation of such energy in Brazil [193,194].…”

“…Considering some restrictions, including a reservoir water level limit of +2.5 m, Neto et al [192] proposed a new model for the tidal power plant in which the three radial sluice gates were replaced by the modern and appropriate version for automatic operation, which excluded the necessity of using stop-log type gates to control the reservoir maximum limit. Considering the Kaplan turbine with double regulation provided by ANDRITZ HYDRO [195], they estimated an annual energy production of slightly larger than 14 GWh/yr for the power plant.…”

This study, firstly, provides an up-to-date global review of the potential, technologies, prototypes, installed capacities, and projects related to ocean renewable energy including wave, tidal, and thermal, and salinity gradient sources. Secondly, as a case study, we present a preliminary assessment of the wave, ocean current, and thermal gradient sources along the Brazilian coastline. The global status of the technological maturity of the projects, their different stages of development, and the current global installed capacity for different sources indicate the most promising technologies considering the trend of global interest. In Brazil, despite the extensive coastline and the fact that almost 82% of the Brazilian electricity matrix is renewable, ocean renewable energy resources are still unexplored. The results, using oceanographic fields produced by numerical models, show the significant potential of ocean thermal and wave energy sources in the northern and southern regions of the Brazilian coast, which could contribute as complementary supply sources in the national electricity matrix.

Summary Increase in the penetration level of renewable resources results in the development of new approaches to assess the impacts of these variable resources on the power network. Large‐scale barrage‐type tidal generation units can integrate to the power network for reliability improvement. For reliability analysis of a power system containing these plants, a reliability model is developed. This model is considered the components' failure and also the output power variation arisen from the change of the tidal height should be developed. For this purpose, a multi‐state reliability model considering variation of tidal height that affects components failure rate and also the value of generated power is developed. The failure rate of components including transformer, turbine, cable, generator and electrical converter is dependent on the tidal height and turbine velocity. The paper is focused on the developing a thermal model for each component. Based on the temperature rise of the components, the associated variable failure rate is calculated from the Arrhenius law. The multi‐state reliability model of barrage‐type tidal energy conversion system considering variable failure rate of components is utilized to study the generation power systems adequacy based on the analytical and Monte Carlo approaches. This model is also utilized for reliability assessment of composite power system containing barrage‐type tidal power plants. Considering variable failure rate of components results in a more accurate reliability model for tidal power plant. Based on this model, the effects of different tidal patterns on the reliability indices can accurately be studied.
