An Anti-Islanding Protection for VSM Inverters in Distributed Generation
Amin, Mohammad; Zhong, Qing-Chang; Lyu, Zijun (Peer reviewed; Journal article, 2020)Virtual synchronous machine (VSM) technology is an attractive control method for an inverter-based distributed generation (DG) due to having the voltage, and frequency support functionality. Embedding an anti-islanding ... -
Go Real: Power Electronics From Simulations to Experiments in Hours: Versatile Experimental Tool for Next Generation Engineers
Zhong, Qing-Chang; Wang, Yeqing; Dong, Yiting; Ren, Beibei; Amin, Mohammad (Peer reviewed; Journal article, 2020)The only constant is change-power systems worldwide are going through a paradigm change from centralized generation to distributed generation; transportation systems are being electrified; and billions of lives in third-world ... -
Impedance Modeling and Stability Analysis of Grid-tied Universal Droop Control Inverter
Amin, Mohammad; Zhong, Qing-Chang (Chapter; Peer reviewed, 2019)This paper presents an impedance modeling and small-signal stability analysis of the grid-tied Universal Droop Control (UDC) inverter. The -impedance model of the UDC inverter is derived analytically and, which is verified ... -
Re-synchronization of Universal Droop Control Distributed Generation Inverter to the Grid
Amin, Mohammad; Zhong, Qing-Chang (Chapter, 2019)The distributed generation (DG) inverters can operate in an islanded mode and a grid-connected mode. Under grid fault conditions, the inverter is disconnected from the main grid and operates in the islanded mode. When DG ... -
Resynchronization of Distributed Generation based on the Universal Droop Controller for Seamless Transfer Between Operation Modes
Amin, Mohammad; Zhong, Qing-Chang (Journal article; Peer reviewed, 2019)Distributed generation (DG) inverters can operate in the islanded mode and the grid-connected mode. When these DG inverters operate in the islanded mode, they often form a microgrid. The magnitude and phase of the main ... -
Smart Grid Research and Educational Kit to Enable the Control of Power Electronic-based Systems from Simulations to Experiments in Hours
Zhong, Qing-Chang; Wang, Yeqing; Amin, Mohammad; Dong, Yiting; Ren, Beibei (Peer reviewed; Journal article, 2021)Control and power electronics are two major enablers for the paradigm shift of power systems from centralized generation to distributed generation, the electrification of transportation, and the transformation of billions ...
