Summary: | The embodiment of the invention discloses an electric energy quality optimization system and an island microgrid. According to the system, a control unit is connected with a standby power supply and an electric energy quality optimization device; the stand-by power supply is used for being connected with a wind generating set system and providing power for the wind generating set system in the debugging stage of the wind generating set system or when an island microgrid is formed by the stand-by power supply and the wind generating set system. The electric energy quality optimization device comprises energy storage equipment connected to the wind generating set system and a voltage, frequency and other stability control device, and the control unit is used for monitoring the frequency of the wind generating set system and controlling the energy storage equipment to discharge to the wind generating set system to improve the frequency when the frequency is smaller than a first frequencythreshold value; and when |
