A Comparative Analytical Study on Low-Voltage Ride-Through Reference-Current-Generation (LVRT-RCG) Strategies in Converter-Interfaced DER Units
DownloadSpring 2015
Mohammadalizadeh Shabestary, Masoud
Recently, riding through grid faults and supporting the grid voltage under faults have become major requirements in distributed energy resource (DER) units. There have been also extensive efforts in academia and industry to develop and implement control strategies to ride through voltage...

Effective Utilization of Distributed and Renewable Energy Resources to Stabilize and Enhance Smart Power Grids Performance
DownloadFall 2017
Fakhari Moghaddam Arani, Mohammadreza
Clean and renewable energy resources such as wind power and photovoltaics, along with advanced environmentally-friendly loads like electric vehicles, will be significant components of future grids. These resources are rapidly increasing, but they have an inherent tendency to degrade system...

Electromechanical Performance Comparison of Low-voltage Ride-through Methods for Variable Speed Wind Turbines
DownloadSpring 2021
The increasing penetration of the renewable wind energy systems and the decommissioning of the traditional fuel systems has resulted in an increasingly strict grid codes to circumvent issues with the grid’s stability and reliability. The low-voltage ride-through (LVRT) requirement is one of the...

Modeling, Analysis and Control of Single and Multiple Micro-grid-Based Active Distribution Grids
DownloadFall 2014
Derived by economic, technical and environmental reasons, the energy sector is moving towards a new era of “Smart Active Distribution Systems” where clusters of converter-based distributed generation (DG) units, local loads and other filtering devices form micro-grids (MG), which can be regarded...

Spring 2019
The direct current (dc) technology has gained significant momentum and widespread acceptance in modern distribution systems due to the high penetration levels of dc loads and dc-based distributed generators (DGs). This thesis presents a detailed analysis, performance comparison, and design...
