Analysis, Design and Control of Asymmetrically Modulated Dual Active Bridge Converters for Energy Storage Systems
DownloadSpring 2021
Energy storage units are widely used in power systems to increase grid reliability to compensate the risks imposed due to massive integration of intermittent sources, as well as serve as spinning reserves. High efficiency dc-dc converters are required as an interface between the storage units and...

Decentralized Schemes for Grid-Forming Inverter System Efficiency Improvement and Online-Inverter Detection
DownloadSpring 2022
Parallel grid-forming (GFM) inverters are used in many modern power system applications. Therefore, improving their system efficiency is of paramount importance for energy savings. The droop control method has been conventionally used to share the power among inverters proportional to their power...

Spring 2020
As the key components of ac distributed generation (DG) units, inverters significantly affect the reliability, efficiency, and power quality of the system. DG inverters are required to i) operate in both grid-connected (GC) and standalone (SA) and seamlessly transfer between these modes, ii)...

New Fast and Accurate Steady-State Analysis Approach for Design, Optimization, and Simulation of General Power Converter Systems
DownloadSpring 2023
Accurate steady-state analysis of power converters are essential for converter design and optimization. Steady-state responses are also useful for component selection, loss calculation, identification of soft switching operation, and small signal modeling of power converters. Normally, a...

Weighted Dynamic Aggregation Approach for Modular Large-scale Power Systems Modeling and Analysis
DownloadFall 2023
Regardless of the power level, many recent power systems are designed with modular and distributed units forming complex systems. Such large-scale systems normally consist of several units with similar hardware and control configurations, which can be connected to the rest of the system at a...
