Standalone operation of wind turbine-based variable speed generators with maximum power extraction capability

Journal Article


Abstract


  • The application of variable speed wind generators in

    hybrid remote area power supply (RAPS) systems provides opportunities

    for improved voltage and frequency control together

    with maximum power point tracking (MPPT), where limited research

    outcomes exist. The study presented in this paper covers

    two such hybrid systems: 1) permanent magnet synchronous generator

    (PMSG) and 2) doubly fed induction generator (DFIG) as

    wind turbine technologies together with a battery storage and a

    dump load. The battery storage system and dump load are able to

    assist in maintaining the active power balance during over and under

    generation conditions as well as sudden load changes. Through

    simulation studies, it has been demonstrated that both RAPS systems

    are able to regulate the load side voltage and frequency within

    the acceptable limits while extracting the maximum power from

    wind, which is an inherent capability of variable speed generators.

    The two RAPS systems and their associated control strategies

    have been developed and their performance is investigated using

    SimPowerSystems blocksets in MATLAB.
