This paper proposes a new structure for grid
synchronization based on generalized integrators (GI) that lead
to fast detection of positive and negative components of the grid
voltage. The GI are used as a band pass ...

Unbalanced voltage sags strongly deteriorate the
performance of power converters and electrical machines
connected to the distribution network. In particular, a reduction
of the power quality is noticed in these equipments, ...

This paper presents a networked control scheme for
a photovoltaic-based industrial microgrid to adaptably operate in
both grid-connected and islanded modes, and even to transfer
smoothly between these two modes. The ...

A high density of grid-connected photovoltaic (PV)
power generation systems is expected to occur in urban areas.
The connection of distributed generation (DG) may cause serious
problems in the distribution system such ...
