Online grid-adaptive control and active-filter functionality of PWM-converters to mitigate voltage-unbalances and voltage-harmonics - a control concept based on grid-impedance measurement
2011
2011 IEEE Energy Conversion Congress and Exposition
This work presents a control concept for a PWMconverter switching with medium-low frequencies (2.5 kHz) based on grid-impedance measurement to adapt the converters control online to variable grid-conditions and to improve the voltage-quality at the converters connection point. Thus, this work contributes to the actual problem of connecting distributed renewable energy sources to the grid. To improve the voltage-quality, additional active-filter functionality is implemented to mitigate
