Negative sequence droop method based hierarchical control for low voltage ride-through in grid-interactive microgrids
Xin Zhao,Mehdi Savaghebi,Josep M. Guerrero,Juan C. Vasquez,Kai Sun,Xiaohua Wu,Guoliang Chen,Libing Sun +7 more
TL;DR: In this article, a voltage support strategy based on negative sequence droop control, which regulates the positive/negative sequence active and reactive power flow by means of sending proper voltage reference to the inner control loop, is proposed for the grid connected MGs to ride through voltage sags under complex line impedance conditions.

A decentralized scalable approach to voltage control of DC islanded microgrids
TL;DR: A new decentralized control scheme for DC Islanded microGrids composed of several Distributed Generation Units (DGUs) with a general interconnection topology that guarantees the total scalability of control synthesis as the ImG size grows or DGUs get replaced.
Proceedings ArticleDOI
Modeling and control of flexible HEV charging station upgraded with flywheel energy storage
TL;DR: A power balancing strategy based on a local energy storage system (ESS) is proposed in this paper and real time simulation results, that prove the validity of proposed approach, have been presented.
Journal ArticleDOI
An Accurate Physical Model for PV Modules With Improved Approximations of Series-Shunt Resistances
Jose Maurilio Raya-Armenta,Pablo Ortega,Najmeh Bazmohammadi,Sergiu Spataru,Juan C. Vasquez,Josep M. Guerrero +5 more
TL;DR: In this article, two new physical equations are introduced to represent the series and shunt resistances, while the other parameters are represented by well established physical expressions, which can be easily applied to other kind of studies where a physical meaning of the PV parameters is of great importance.
Proceedings ArticleDOI
Stability constrained efficiency optimization for droop controlled DC-DC conversion system
TL;DR: A hierarchical control in a droop-controlled dc-dc conversion system with special focus on improving system efficiency which is dealt within the tertiary regulation is implemented.
