Distribution Power Loss Mitigation of Parallel-Connected Distributed Energy Resources in Low-Voltage DC Microgrids Using a Lagrange Multiplier-Based Adaptive Droop Control

Yajie Jiang et al.

Summary: This article presents a Lagrange multiplier-based adaptive droop control to mitigate distribution power loss of parallel-connected distributed energy resource (DER) systems in dc microgrids. The proposed control strategy reduces distribution power loss in 48 V dc microgrids with parallel-connected DER systems compared to conventional control strategies by optimizing the output current references.

Adaptive Droop-Based Control for Active Power Sharing in Autonomous Microgrid for Improved Transient Performance

Surya Prakash et al.

Summary: This article introduces a decentralized adaptive droop-based control for active power sharing between parallel inverters in autonomous microgrids, focusing on improving the transient performance of the system through proposing a robust controller. The proposed method does not require load current measurement and considers dynamics due to resistances across the LC filter configuration. Controller gain conditions are analyzed using a detailed Lyapunov analysis for practical application.
