Problems solved by technology

However, these methods are all carried out for ideal sea areas, and cannot be directly applied to the layout planning of tidal current power plants considering unfeasible areas.
The disadvantage of this method is that it ignores the influence of the unfeasible area on the tidal flow rate, and it is difficult to fully exploit the potential of tidal current energy power generation and improve the capital utilization rate of tidal current energy power plants.
