A review on the development of tidal current energy in China

Renewable and Sustainable Energy Reviews, 2011
Nowadays and in the coming years, increased attention is being given to the tidal current energy development all over the world. China is a country endowed with abundant tidal current energy resources. In this paper, the distribution of tidal current energy in China was presented. Policies and current status of usage and technology development of tidal

Limits to the predictability of tidal current energy

OCEANS 2010 MTS/IEEE SEATTLE, 2010
The predictability of tidal currents in the context of hydrokinetic power generation are assessed using current data from a series of surveys in Admiralty Inlet, Puget Sound, Washington, USA. Both current speed and kinetic power density are shown to be well-described by harmonic analysis. Three challenges to predictability are identified.

State of the art for tidal currents electric energy resources

2011 24th Canadian Conference on Electrical and Computer Engineering(CCECE), 2011
Renewable energy is an effective and clean source of supplying electrical loads especially in remote and rural areas. In this paper we discuss tidal in-stream energy as it relies on the same technologies developed from offshore wind turbines for generating electricity at offshore sites.

Tidal and current energy

2019
The book chapter deals with both tidal rise and fall energy and hydrokinetic energy from tides, ocean currents and rivers. (River energy is included because the proposed technologies share some characteristics with those proposed for tidal currents.) Out of the many devices proposed, some have been built, but most of these have disappeared as a result ...

Turbines for modular tidal current energy converters

Renewable Energy, 2019
Abstract The vast potential of ocean energies is of increasing interest. Harnessing marine currents driven by the tidal cycle have triggered the development of various power conversion systems. However, the comparably high levelized cost of electricity is still the main hindrance for a faster market penetration.

A Representation of Tidal Currents Based on Energy Flux

Marine Geodesy, 2001
This article shows that the current associated with a tidal constituent can be represented as the sum of two vectors, one in phase with the surface elevation, the other in quadrature with the elevation. The in-phase component, which accounts for all the mean energy flux, resembles a traveling wave, while the quadrature component has some properties in ...

Design context for tidal current energy: The Agulhas current stream

2010 IEEE International Energy Conference, 2010
This paper presents an overview of the design and operation of tidal energy conversion systems. The authors discuss tidal energy as a form of renewable energy in comparison to wind energy, especially the close resemblance between the design and operation of the turbine principles used for the two types of renewable energy.
