The low voltage ride-through (LVRT) requirements demand large-scale photovoltaic (PV) power generation system remain connected to the grid during faults. It results in considerable impact on characteristics of fault current. This paper combines charge-discharge energy storage (ES) with PV enhance LVRT capability. Based inverter control strategy and specific requirements, current PV-ES is discus...

Brushless double fed induction generator (BDFIG) based machines have gained popularity in wind turbine applications because of their easily accessible design. Low voltage ride through (LVRT) is critical for the reliable integration renewable energy with power grid. The refore, LVRT capability brushless DFIGs makes them an attractive choice maintaining stability existing works on BDFIG control s...

Due to the growing concerns regarding environmental and economic issues in power systems, nowadays application of renewable energy sources (RES), especially wind has been increased. However, increasing penetration plants (WPPs) into grid raised numerous challenges including output fluctuations as well significant role these play low-voltage ride-through (LVRT) case short circuit fault condition...

In this paper performance analysis of Doubly Fed Induction Generator under abnormal condition is analysed. In recent years, this series compensated transmission system will produce unwanted effect of sub synchronous resonance. Super Conducting Magnetic Energy Storage (SMES) provides an efficient damping for sub synchronous resonance that will enhance power system stability in addition to real a...

The paper presents a current controlled High Frequency AC (HFAC) link based on Matrix Converter (MC) to interface a photovoltaic (PV) system with the grid. The proposed switching scheme for the MC is based on the hysteresis current control and the sign of the input voltage waveform. A strategy for controlling the HFAC link converter to extract the maximum power by regulating the terminal voltag...

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...

The integration of wind generation to the grid is growing rapidly across world. As a result, operators have introduced so-called codes (GC), which nowadays include range technical conditions and requirements, generators must fulfill. Among these, low-voltage ride through (LVRT) requirement for turbines stay connected continue operate during disturbance. In this study, control structure, combini...
