Improvement of Frequency Stability in the Power System Considering Wind Turbine and Time Delay

Farhad Amiri; Mohammad Hassan Moradi

Volume 10, Issue 1 , January 2023, , Pages 9-18

  In the power system, frequency stability is critical. The wind turbine oscillates (depending on the wind speed) and is of low inertia. Thus, wind turbines face the issue of power system frequency stability. Since the power system's resources are interconnected via communication networks, the presence ...  Read More

Nemat Keramat Siavasha; Gholamhasan Najafi; Teymour Tavakoli; Barat Ghobadian; Esmail Mahmoodi

Volume 4, Issue 4 , December 2017, , Pages 49-56

  Ducted wind turbines are a kind of small wind turbine having a diffuser or any other shape around the rotor which increases the air flow through the blades and absorbs more power. In the present study, a small wind turbine was ducted with a relatively simple ring and its performance was investigated ...  Read More

The Ranking of Southern Ports and Islands of Iran for Seawater Desalination Plants Using ELECTRE III Method

Ali Mostafaeipour; Mohammad Saidi-Mehrabad; Mostafa Rezaei; Mojtaba Qolipour

Volume 4, Issue 2 and 3 , September 2017, , Pages 10-22

    The energy insecurity, environmental pollution, climate change and even reduced rainfall in some countries are prime examples of consequences of the world’s excessive reliance on fossil fuels. This study suggests that in some southern islands and coastal areas of Iran, two such problems, ...  Read More

Sliding-Mode-based Improved Direct Active and Reactive Power Control of Doubly Fed Induction Generator under Unbalanced Grid Voltage Condition

Gholam Reza Arab Markadeh; Nasrin Banimehdi

Volume 3, Issue 2 , May 2016, , Pages 24-34

  This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control ...  Read More
