Abstract
In order to solve the problems that grid connected inverters cannot share power accurately in different line impedance. A new control method for grid connected inverters is presented in this paper. The new control method combines adaptive droop coefficient droop control with fuzzy PID control. The system consists of two sets of three-phase inverters which are controlled by current voltage dual-loop, an improved droop loop and fuzzy PID controller. The adaptive droop coefficient droop control can overcome the system cannot share power accurately in different line impedance, and the fuzzy PID controller can improve the system response speed and reduce system.waveform distortion. Simulation results show the good performance of the scheme.
