Voltage Control and Load Sharing in a DC Islanded Microgrid Based on Disturbance Observer
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 کاملNew Power Sharing Control for Inverter-Dominated Microgrid Based on Impedance Match Concept
Power flow control is one of the most important issues for operating the inverter-dominated autonomous microgrid. A technical challenge is how to achieve the accurate active/reactive power sharing of inverters. P-F and Q-V droop control schemes have been widely used for power sharing in the past decades. But they suffer from the poor power sharing in the presence of unequal line impedance. In o...
متن کاملControl of a DC Microgrid
A microgrid is a part of a distribution network embedding multiple distributed generation systems (mostly nonconventional renewable energy sources like photovoltaic panels, small wind turbines etc.) and storage systems with local loads, which can be disconnected from the upstream network under emergency conditions or as planned. The microgrid concept naturally arose to cope with the penetration...
متن کاملNonlinear control applied to a dc-dc power converter and the load sharing problem in a dc microgrid ?
The purpose of this paper is to apply the Immersion & Invariance and Passivitybased Control to a dc-dc power converter driving a nonlinear load. Experimental results are shown in order to evaluate the performance of the proposed control techniques. Another goal is to find a model for a dc microgrid (load sharing problem) and to show some stability issues.
