This paper presents a comprehensive study on the state-of-the-art and emerging wind
energy technologies from the electrical engineering perspective. In an attempt to decrease …

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

Wind power now represents a major and growing source of renewable energy. Large wind
turbines (with capacities of up to 6–8 MW) are widely installed in power distribution …

Multilevel converters have been under research and development for more than three
decades and have found successful industrial application. However, this is still a technology …

Power quality and voltage control are among the most important aspects of the grid-
connected power converter operation under faults. Nonsinusoidal current may be injected …

Cascaded multilevel inverters synthesize a medium-voltage output based on a series
connection of power cells which use standard low-voltage component configurations. This …

Multimegawatt wind-turbine systems, often organized in a wind park, are the backbone of
the power generation based on renewable-energy systems. This paper reviews the most …

This paper presents a new multiresonant frequency-adaptive synchronization method for
grid-connected power converters that allows estimating not only the positive-and negative …

Intentional islanding describes the condition in which a microgrid or a portion of the power
grid, which consists of a load and a distributed generation (DG) system, is isolated from the …

In grid-connected applications, the synchronous reference frame phase-locked loop (SRF-
PLL) is a commonly used synchronization technique due to the advantages it offers such as …
