The Grid Connection of Linear Machine-Based Wave Power Generators

Chapter


Abstract


  • The ocean is a gigantic source of renewable and predictable green

    energy. The ocean alone can provide around 10 TW of energy to the total world

    energy demand. The ocean energy, in general, and the wave energy, in particular,

    has gained the attention of researchers because of its huge potential in the past few

    decades. In most cases, the output power of a single wave energy conversion

    (WEC) device is low, and these devices need to be connected in a wave farm (WF),

    like the wind farms, to supply the local load or to interface with the utility grid. This

    chapter gives a detailed insight into the grid integration of the wave farms. The

    output power characteristics of a single machine are first analyzed for the later

    analysis of the combination of multiple machines in a WF. The layout of the WFs is

    described in this chapter. The WF output may be integrated with the utility grids of

    varying strengths in terms of its short circuit ratios and impedance angles. Various

    transmission topologies for connection of the WFs with the offshore utility grids are

    also discussed. The challenges resulting from the grid intergration, such as the

    flicker level, the voltage fluctuations, the low voltage ride through capability and

    the voltage and current harmonic distortions are discussed along with the possible

    solutions to overcome these difficulties. The recent development in the wave energy

    sector of Australia is also presented at the end of the chapter.
