Multi-level bus voltage compensation of droop control with enhanced load-sharing capability for DC microgrid

The Journal of Engineering, 2019
In DC microgrid, droop control is an essential part of local primary level in hierarchical control to perform load-sharing and plug-and-play function. The main problem with droop control is that better load sharing is achieved at the cost of higher bus ...

Data‐Driven Printability Modeling of Hydrogels for Precise Direct Ink Writing Based on Rheological Properties

Advanced Science, EarlyView.
A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

New Perspectives on Droop Control in AC Microgrid [PDF]

IEEE Transactions on Industrial Electronics, 2017
Virtual impedance, angle droop and frequency droop control play important roles in maintaining system stability, and load sharing among distributed generators (DGs) in microgrid. These approaches have been developed into three totally independent concepts, but present strong relevance.

Engineered GM1 Intersects Between Mitochondrial and Synaptic Pathways to Ameliorate ALS Pathology

Advanced Science, EarlyView.
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease driven by genetic and molecular disruptions affecting energy balance, protein homeostasis, and stress responses in nerve cells. Studies using human and rodent models identified convergent defects in mitochondria and synaptic function.

Structural Resemblance Between Droop Controllers and Phase-Locked Loops

IEEE Access, 2016
It is well known that droop control is fundamental to the operation of power systems and now the parallel operation of inverters, while phase-locked loops (PLLs) are widely adopted in modern electrical engineering.

Distributed Adaptive Droop Control for DC Distribution Systems [PDF]

IEEE Transactions on Energy Conversion, 2014
Summary form only given: A distributed-adaptive droop mechanism is proposed for secondary/primary control of dc microgrids. The conventional secondary control that adjusts the voltage set point for the local droop mechanism is replaced by a voltage regulator.

Current-Limiting Droop Control of Grid-Connected Inverters [PDF]

IEEE Transactions on Industrial Electronics, 2017
A current-limiting droop controller is proposed\ud for single-phase grid-connected inverters with an\ud LCL filter that can operate under both normal and faulty\ud grid conditions. The controller introduces bounded nonlinear\ud dynamics and, by using nonlinear input-to-state stability\ud theory, the current-limiting property of the inverter is ...
