Journal ArticleDOI
A Decentralized Dynamic Power Sharing Strategy for Hybrid Energy Storage System in Autonomous DC Microgrid
TL;DR: An extended droop control (EDC) strategy to achieve dynamic current sharing autonomously during sudden load change and resource variations for hybrid energy storage system is proposed.
Journal ArticleDOI
A Novel Composite Nonlinear Controller for Stabilization of Constant Power Load in DC Microgrid
TL;DR: A composite nonlinear controller is proposed for stabilizing dc/dc boost converter feeding CPLs by integrating a nonlinear disturbance observer (NDO)-based feedforward compensation with backstepping design algorithm with strictly guaranteed large signal stability.
Journal ArticleDOI
Review on Advanced Control Technologies for Bidirectional DC/DC Converters in DC Microgrids
TL;DR: An overview of advanced control technologies for bidirectional dc/dc converters in dc microgrids and applications in other high-gain nonisolated and isolated converters for high-power applications is presented.
Journal ArticleDOI
Distributed Secondary Control for Power Allocation and Voltage Restoration in Islanded DC Microgrids
TL;DR: This paper presents a distributed secondary control scheme for accurate power allocation and voltage restoration in islanded dc microgrids and employs the idea of pinning control, which can be further simplified by only sending the dc bus voltage to one DG.
Journal ArticleDOI
A Decentralized Power Management Strategy for Hybrid Energy Storage System With Autonomous Bus Voltage Restoration and State-of-Charge Recovery
TL;DR: A high-pass filter-based droop controller is proposed to regulate the battery converter, and a virtual capacitance droop (VCD) controller is implemented for a supercapacitor (SC) converter to solve the problem in a decentralized manner.
