The increase in penetration of wind farms operating with doubly fed induction generators (DFIG) results stability issues such as voltage dips and high short circuit currents the case faults. To overcome these issues, to achieve reliable sustainable power from an uncertain source, fault current limiters (FCL) are incorporated. This work focuses on limiting level fulfilling reactive compensation ...

This paper proposes a control technique for large-scale grid-connected photovoltaic (PV) plant that maintains the connection of an inverter to grid voltage under different types faults, while injecting reactive power accommodate required connection. strategy is suggested improve low-voltage ride-through (LVRT) capability PV generation plants. A 20 MW solar modeled and simulated using Matlab/Sim...

In a high proportion of new energy grids or 100% source power grid, the dynamic performance PMSG under fault conditions is very important. However, current small signal model lacks detailed and deep analysis permanent-magnet synchronous generator (PMSG)-based wind generation LVRT control. Here, pre-fault, after failure recovery stages are established. This paper employs linear analyses to chara...

In this paper, the authors investigated a Direct Drive Permanent Magnet Synchronous Generator Wind Turbine (PMSG-WT). This study deals with control of the PWM back-to-back converter (AC/AC) of the wind turbine, since the average size of WTG installations has increased due to the advent of larger capacity machines, especially variable speed technology, this raise of integration rate of wind ener...
