Voltage Stabilization and Decoupling Droop Control Method for Microgrid Based on RGA
摘要
Abstract
Flexible operation of a microgrid depends on advanced control methods. The characteristics of lines parameters in microgrid cause the power coupling problem in microgrid control system, affecting the accurate independent control of microgrid. Decoupling theory was applied to solve the problem. The coupling condition of microgrid power transmission model was quantified by the relative gain array method to match and restructure the input and output variables of microgrid power transmission model, and the control system coupling process of two different matching schemes were analyzed. To eliminate the coupling channel, virtual resistance unit was introduced into the micro source power interface control system, and the influence of virtual resistance and control parameters on the stability of control system and power interface output impedance was analyzed. The voltage difference feedback loop was applied to realize the voltage stabilization control, and the voltage drop caused by the virtual resistance was eliminated. The simulation results verified the correctness and validity of the proposed method.关键词
