微电网的电压质量控制方法
Voltage Quality Control Method for Microgrid
摘要
Abstract
To solve the voltage quality problems caused by unbalanced load access and improve the voltage quality at thepoint of common coupling for microgrid,a secondary control method for voltage quality is proposed in this paper. Based on an αβ coordinate system,the voltage,frequency,and power of microgrid are compensated and corrected us?ing a hierarchical control strategy.The basic parameters of microgrid are tracked and controlled by the primary control, and the stable operation of microgrid is maintained by adjusting those parameters.The secondary controlis used for cor?recting the voltage amplitude,frequency,and reactive power deviation of microgrid,respectively,as well as for the com?pensation and sharing of unbalanced voltage and power.Finally,the verification of the simulation model proves that the proposed control method can improve the voltage quality effectively.关键词
