Power sharing for inverters based on virtual synchronous generator control

Abstract

Power sharing is the most important challenging today, especially for parallel operation inverters. Recently to fixed this problem the virtual synchronous generator control strategy has been used. This paper introduced the parallel operation of three-phase multilevel inverters with different capacities to share load power by used a newly strategy named VSG with droop method controller. The control strategy is used to make the inverters to emulate the transient and dynamic charateristics of conventional synchronous generator and to gives accurate load sharing among the inverters in proportional to their ratings. To verify the performance of the proposed technique MATLAB/Simulink package for simulation experiment is established.
