An ANN-based protection technique for MTDC systems with multiple configurations
Alexandria Engineering Journal, 2023 A unified protection technique for different configurations of Multi-Terminal high voltage Direct Current (MTDC) systems is presented in this paper. The technique is based on using positive and negative poles’ currents of one end for each line.

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”.
