Analysis, Design, and Performance Evaluation of Droop Current-Sharing Method

چکیده
The droop current sharing method is analyzed, and a general design procedure is proposed. It is shown that the current-sharing accuracy of N+1 power supplies is a function of the output-voltage set-point accuracy, the slope of the outputvoltage droop, and gains of the control loop. It was found that to achieve a current sharing accuracy of 10% the output voltage of the paralleled power supplies needs to be set within 0.35%. The accuracy of the design procedure was compared against measured results of three power supplies operating in parallel.

Increasing DC loads along with DC nature of distributed energy resources (DERs) raises interest to DC microgrids. Conventional droop/non-droop power-sharing in microgrids suffers from load dependent voltage deviation, slow transient response, and requires the parameters of the loads, system and DERs connection status. In this paper, a new nonlinear decentralized back-stepping control strategy f...

متن کاملImprove the Reactive Power Sharing by Uses to Modify Droop Characteristics in Autonomous Microgrids
Usually, the conventional droop methods is utilized for control of autonomous micro-grids. In islanded micro-grids (MG), due to the effects of mismatch in line impedance, the reactive power can't share by using the conventional droop method. In this paper, a method is proposed to improve reactive power sharing. In this method, the micro-sources are acted with P-w & Q-E droop characteristics, an...
