Smooth Switching Strategy Between Grid-Connected and Islanded Microgrid Using Improved Phase Control Method
Translated Abstract
Amicrogrid mode control system including power control, amplitude control and phase controlwas designed for smoothswitchbetween grid-connected and islanded microgridmodeswith master-slave control.Aload transfer strategy on active isolatingwas introduced to reduce impact on mastercontrol. Anovelphase control method without PLLwas proposed.Compared to conventional method, the proposed method with simple structure not only achieved pre-synchronizationcontrol of islanded microgrid to main grid, butalso ensuredfrequency stabilityand phase continuity duringcontrol mode transition. A simulation platform of a microgrid was established, andtransients of passive isolating, active isolating and transition from islanded to grid-connected mode were analyzed.Itverified validityand superiority of the proposed control strategy.
