Cost- benefit analysis of two dissimilar warm standby system subject to failure due to tides and g ravitational

However, many recent technological developm both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher than previously assumed, and that economic and environmental costs may be brought down to competitive levels.

Temporal Evolution Assessment of Dynamic Tidal Power Including Turbine Effects

Abstract: Dai, P.; Zhang, J., and Xiao, L., 2020. Temporal evolution assessment of dynamic tidal power including turbine effects. Journal of Coastal Research, 36(5), 1050–1058. Coconut Creek (Florida), ISSN 0749-0208.The dynamic tidal power system adopts a coast perpendicular dike in capturing tidal potential energy and is basin free as opposed to the conventional tidal barrage system. Since it is important for the developers to have detailed information of the power output characteristics prior to implementation, the temporal evolution of the power output has been studied to improve the understanding of the dynamic tidal power resource using a two-dimensional hydrodynamic model. The model accurately simulates the tidal motion characteristic of Chinese marginal seas. As an essential input for the temporal power estimation, the turbine operation is taken into account for this study, while the watertight dike has often been considered in previous feasibility studies. The results show that the monthly average power output increases, reaches a maximum, and then decreases with an increase in the number of turbines. The temporal evolution of power is featured by strong semidiurnal intermittency due to the semidiurnal tide. The peak power is recorded as 2.81 GW during spring tide, when 8% of the dike is opened for turbines. The magnitude reduces in both the middle and neap tide stages. Four peaks in the monthly average hourly power variation histogram were picked up, with much more homogeneity as compared with the power series during any specific tidal stage. Structurally, the T-branch added to the seaward tip of the I-shaped system is called the T end and forms the T-shaped system. It is proposed that this T-shaped system leads to an increase in production. The T end harvests substantially greater M2 energy than K1 energy near the seaward end of the system. The concentration of M2 energy contributes to the improvement in power production.

A Case Study of Energy Harvesting by Dynamic Tidal Power in the Persian Gulf

Abstract: Dynamic Tidal Power (DTP) is one of the most recent methods of exploiting the energy of tides Although most of the studies regarding this revolutionary method aim at the Yellow and Bohai seas in China, the evaluation of this method in other potential locations in the world is of considerable importance This study provides preliminary insights and assessments about the use of this method in Faror strait in the Persian Gulf By using a 3D numerical model of a full-scale domain, the maximum water level difference between the two sides of the DTP dam is found to be about 12 meters at the maximum water speed in the strait with a total available power of 760 MW Furthermore, among the existing technologies for electric generators, a direct-drive permanent magnet synchronous generator has proved to be the best choice for the electric power generation system Moreover, it has been concluded that power electronic converters are required to make the generated voltage compatible with the grid voltage
