Today, conventional power systems are evolving to smart grids, which encompass clusters
of AC/DC microgrids, interfaced through power electronics converters. In such systems …

With the exponential penetration of Photovoltaic (PV) plants into the power grid, protection
has gained exceptional importance in recent years for ensuring stability, reliability, security …

Ancillary services for distributed generation (DG) systems become a challenging issue to
smartly integrate renewable-energy sources into the grid. Voltage control is one of these …

In the last few years, restrictive grid codes have arisen to ensure the performance and
stability of electrical networks, which experience a massive integration of renewable energy …

This paper presents a new control strategy for a doubly fed induction generator (DFIG) under
unbalanced network voltage conditions. Coordinated control of the grid-and rotor-side …

This paper proposes an improved vector space decomposition current control scheme for
dual three-phase permanent magnet (PM) synchronous motors having two sets of three …

This paper proposes an algorithm for coordinated control of the distributed generators
integrated to a dc microgrid (DCMG), in islanded and grid connected modes of operation …

Although HVDC transmission systems have been available since mid-1950s, almost all
installations worldwide are point-to-point systems. In the past, the lower reliability and higher …

Currently classical thyristor-based high voltage direct current (HVDC) systems hold the
market in bulk power transmission. However, recent advances in semiconductor technology …

In this paper, the behavior of a doubly fed induction generator (DFIG) is studied under
unbalanced grid voltage conditions. It is shown that if no special control efforts are …
