Wave energy is a significant untapped renewable energy source which can be harnessed
by wave energy converters (WECs). The oscillating water column (OWC) is one of the most …

As theincrease of wind power penetration, the fluctuations of wind power results in serious
power system frequency turbulences. This article proposes a low-pass virtual filter (VF) for …

In this paper, an advanced pitch angle control strategy based on the fuzzy logic is proposed
for the variable-speed wind turbine systems, in which the generator output power and speed …

This paper presents a small signal modeling of a direct-driven permanent magnet
synchronous generator (PMSG) based on wind turbine which is connected to the grid via …

This paper deals with power extraction maximization of a doubly fed induction generator
(DFIG)-based wind turbine. These variable speed systems have several advantages over …

Renewable energy technique is gaining more interest due to increasing demand and threat
