Frequency regulation of multiple asynchronous grids using adaptive droop in high-voltage direct current system [PDF]

, 2020
Frequency stability control in multiple asynchronous grids is a challenging and complex issue. An adaptive droop control strategy to improve the frequency regulation of asynchronous AC areas connected by a multi-terminal DC grid is proposed here.
