Demonstration of sustained and useful converter responses during balanced and unbalanced faults in microgrids [PDF]
, 2012 In large power grids where converter penetration is presently low and the network impedance is predominantly reactive, the required response from converters during faults is presently specified by phrases such as “maximum reactive output”.
