In this paper the effect of presence of wind farms on relay coordination at fault condition and transient response at reclosing condition is studied. Wind farms as one of the important distribution generations (DGs) are so effective on overcurrent relay coordination in power systems. As well as Wind farms cause to severe oscillations on voltage, power and frequency in power system after reclosi...

This paper presents an improved control strategy for both the rotor side converter (RSC) and grid side converter (GSC) of a doubly fed induction generator (DFIG)-based wind turbine (WT) system to enhance the low voltage ride through (LVRT) capability. Within the proposed control strategy, the RSC control introduces transient feed-forward compensation terms to mitigate the high frequency harmoni...

This paper proposes an isolated buck-boost topology and control strategy for the photovoltaic (PV) medium-voltage DC (MVDC) converter with low-voltage ride through (LVRT) capability. The proposed operates on either boost or buck mode by only controlling active semiconductors side. Based this topology, (MV) dc–dc module is able to be developed reduce number of modules increase power density in c...

With the increasing penetration of wind power, large-scale integrated turbine brings stability and security risks to power grid. For aggregated modeling large farms, it is crucial consider low voltage ride-through (LVRT) characteristics. However, in aggregation methods, approximate neglect behavior essential, which leads inevitable errors process. Moreover, lack parameters practice new challeng...

A fault current limiter (FCL) may be applied to assist the low-voltage ride-through (LVRT) of a doubly fed induction generator (DFIG). FCLs with fixed impedance, lack flexibility adjust their impedance adapt different LVRT scenarios. The direct switch-in and -out fixed-impedance FCL yields transient electromagnetic oscillations in DFIG, which need addressed. In this paper, variable-impedance is...

Distributed power generation plays a critical role in the stability and reliability of modern systems. Due to rapid growth renewable energy generation, requirements transmission distribution system operators are becoming more stringent. Among these requirements, one most important is Low-Voltage Ride-Through (LVRT) capability, which demands that inverters remain connected grid provide support d...

This paper presents a new multi-objective control strategy for inverter-interfaced distributed generation (IIDG) to ensure its safe and continuous operation under unbalanced voltage sags. The proposed can effectively improve the low ride through (LVRT) capability, reduce active power oscillations, limit overcurrent simultaneously, which are marked as most important objectives of IIDG during adv...
