Controlling of Zero-sequence Circulating Current in Parallel Microgrid Energy Storage Converters
摘要
Abstract
According to the actual behavior exhibited in microgrid(MG)system,an improved master-slave control strategy was proposed,feedforward value to the current inner loop was increased and initial value to the inner integrator was given and initial value to the phase angle was given,based on conventional PQ/Vf transfer. DC-link double parallel three-phase voltage converters were implied,to improve the reliability of the controller and expansion. Effective circulation current controller was designed,and the circulating current brought by paralleled module was restrained by regulating the zero sequence components of duty cycle of three-phase bridge. Finally,the validity of the proposed control method is verified in Matlab/Simlink,achieving seamless transfer and restraining the zero-sequence circulating current between paralleled inverters.关键词
