Wave and Tidal Power Generation

Abstract: Renewable energy is natural energy which does not have a limited supply. Renewable energy can be used again and again, and will never run out. Now- a -days, the energy which is used in the universe divided into two parts. One is the non-renewable or conventional other is renewable or non-conventional energy, classification of energy is shown below by a checker board. Tidal Power is the generation of electrical power through the harnessing of the ebb and flow of the tides or Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into electricity or other useful forms of power. Only a few such plants exist. The largest is the Range Tidal Power Station, on the Rance River, in France, which has been operating since 1966, and generates 240MW. Smaller plants include one on the Bay of Fundy, and another across a tiny inlet in Kislaya Guba, Russia).

A review of hydrodynamic investigations into arrays of ocean wave energy converters

Abstract: Theoretical, numerical and experimental studies on arrays of ocean wave energy converter are reviewed. The importance of extracting wave power via an array as opposed to individual wave-power machines has long been established. There is ongoing interest in implementing key technologies at commercial scale owing to the recent acceleration in demand for renewable energy. To date, several reviews have been published on the science and technology of harnessing ocean-wave power. However, there have been few reviews of the extensive literature on ocean wave-power arrays. Research into the hydrodynamic modelling of ocean wave-power arrays is analysed. Where ever possible, comparisons are drawn with physical scaled experiments. Some critical knowledge gaps have been found. Specific emphasis has been paid on understanding how the modelling and scaled experiments are likely to be complementary to each other.

Wave period group statistics for real sea waves and wave energy extraction

Abstract: The paper describes the analyses of wave data recorded at various locations and water depths around northern Europe to determine the temporal characteristics of individual wave periods and other wave period statistics. These analyses show that, just as there are group characteristics for wave heights, there are similar, but less pronounced, characteristics for wave periods. This is observed in three separate sets of data from different locations in water depths of 18, 50, and 130 m. It is also found in time series simulated using random linear wave theory from a Jonswap spectrum. A simple, new statistic, R, is introduced that measures the rate of change in the wave period from one wave to the next. This is relevant to wave energy devices that may try to tune themselves to obtain optimum power output from each individual wave. The characteristics of this statistic and its variation with significant wave height, mean energy period, and spectral bandwidth have been examined for the three datasets and are dis...
