Weak Grid Characteristic Analysis and Operating Mode Selection for Voltage Support Enhancement of Wind Farms Connected to MMC-HVDC During Asymmetric Faults

IEEE transactions on power electronics
The voltage support functions have been mandated in grid codes to help wind turbines (WTs) ride through ac faults. In a modular multilevel converter-based high voltage dc (MMC-HVDC) system for wind farm integration, particularly in scenarios where there ...

Analysis of frequency inverter supportability to voltage sags

2018 Simposio Brasileiro de Sistemas Eletricos (SBSE), 2018
This work presents a study about the tolerance of a frequency inverter when submitted to voltage sags, which are events directly related to the electric power quality. The frequency inverters are devices widely used in the industry applications in variable speed drives. According to the magnitude and duration of the voltage sag, the frequency inverters

Evaluation of the Voltage Support Strategies for the Low Voltage Grid Connected PV

2010
Admissible range of grid voltage is one of the strictest constraints for the penetration of distributed photovoltaic (PV) generators especially connection to low voltage (LV) public networks. Voltage limits are usually fulfilled either by network reinforcements or limiting of power injections from PVs. In order to increase PV penetration level further,
