  • Publication number: 20180128165
    Abstract: Abrupt output fluctuation of renewable energy is smoothed by output control of a prime mover driven generator and curtailment of renewable energy. The generator is a doubly-fed induction generator and a rotor creates a rotating magnetic field by being energized with AC through a power converter and makes a frequency of the AC variable so as to change speed of the rotor and receive and output inertial energy that the rotor has. In a case where an output of renewable energy is abruptly increased and curtailment of the prime mover is not made in time, output fluctuation is smoothed by suppressing the output of renewable energy at the same time while increasing the speed of the rotor to be absorbed as inertial energy.
