Control of Self-Adaptive Droop Coefficient for Inverter in Low Voltage Microgrid
摘要
Abstract
Due to the amplitude and frequency of output voltage of inverter was unstable with conventional droop control in microgrid,an improved adaptive droop control was proposed,which added error feedback of voltage and frequency.So it could reduce the deviation of output voltage amplitude and frequency when loads suddenly changed.At the same time the traditional three-phase inverter control based on the dq rotating coordinate system,the assault of power to grid was very large,but control based on αβ stationary coordinate system could effectively reduce the assault of power to grid,and it improved the stability of the system.Through the MATLAB simulation,verified the feasibility of the system which used the method proposed.关键词
