New Approach for Modeling of Robust Droop Control for Equal Load Sharing between Parallel Operated Inverters

Abstract

This paper proposes a new approach for robust droop control with the objective of equivalent power sharing between parallel inverters  in islanded microgrid as well as stability, using close loop voltage and current controller. The past droop controller uses conventional (PI) close loop voltage and current controller. The approach for proposed controller is it uses PR controller for close loop voltage and current control in modeling of robust droop control. The simulated results shows improve stability of frequency reference by limiting the frequency error, improved voltage quality and also exhibit equal power sharing between two parallel inverter considering different output impedence.
