Renewable energy sources are one key enabler to decrease greenhouse gas emissions
and to cope with the anthropogenic climate change. Their intermittent behavior and limited …

In recent years, voltage sags are one of the most critical research issues in the field of power
quality. With the all-embracing study of voltage sag mitigation measures and equipment, the …

Solid-state transformer (SST) and hybrid transformer (HT) are promising alternatives to the
line-frequency transformer (LFT) in smart grids. The SST features medium-frequency …

This paper deals with improving the voltage quality of sensitive loads from voltage sags
using a dynamic voltage restorer (DVR). The higher active power requirement associated …

This paper presents an optimized sliding mode control (SMC) strategy to maximize
existence region for single-phase dynamic voltage restorers. It is shown analytically that …

Dynamic voltage restorer (DVR) is a definitive solution toward compensation of voltage sag
with phase jump. Conventional DVR topologies, however, have dc links and two-stage …

This paper presents a new system configuration for integrating a grid-connected
photovoltaic (PV) system together with a self-supported dynamic voltage restorer (DVR). The …

Distribution systems are under constant stress due to their highly variable operating
conditions, which jeopardize distribution transformers and lines, degrading the end-user …

Hybrid distribution transformer (HDT) is a promising device for constructing the future active
distribution network. To overcome the limitations of the existing HDT control schemes, a …

This article proposes a new architecture for the hybrid distribution transformer (HDT) with a
partially rated power converter connected in series with the existing distribution transformer …
