In today’s world, the DG should not be disconnected in event of a power outage but instead remain linked to grid and supported by reactive power. This can accomplished implementing low voltage ride through (LVRT) with proportional integral (PI) controller. As result, profile enhanced. The PI controller, on other hand, has drawbacks that setting gain takes long time results an overshoot current ...

Brushless doubly-fed induction generators have higher reliability, making them an attractive choice for not only offshore applications but also remote locations. These machines are composed of two back-to-back voltage source converters: the grid side converter and rotor converter. The is typically used reactive current control power winding using current. A low ride through (LVRT) fault detecte...

Permanent-magnet synchronous generator (PMSG) are used widely in wind turbine applications. The performance analysis of PMSG can be enhanced by adopting a number control mechanisms with the benefit advanced optimization techniques. Renewable energy is harnessed from continuously replenishing natural processes. Some commonly known sunlight, water, wind, tides, geothermal heat and various forms b...

Wind turbine generators (WTGs) are highly sensitive to the disturbances of grid and tend disconnect quickly during a voltage dip (when value is less than 80% nominal voltage) or when frequency greatly changed. As an increasing number permanent magnet synchronous (PMSGs) incorporated into modern power grid, system operators expect PMSG-WT play active role in low-voltage ride-through (LVRT) prima...

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...

Recently, the penetration of renewable energy sources (RESs) into electrical power systems is witnessing a large attention due to their inexhaustibility, environmental benefits, storage capabilities, lower maintenance and stronger economy, etc. Among these RESs, offshore wind plants (OWPP) are ones most widespread that have emerged with regard being competitive other technologies. However, appl...
