Grid Resilience by Power Electronics: Use Subtransmission HVDC Interties for Novel Emergency Power Control of Split Networks [Expert View]

Grid resilience by power electronics use subtransmission HVDC interties for novel emergency power control of split networks Modern society is becoming increasingly dependent on reliable electric grids. For years, many critical functions have used backup systems to maintain normal or basic functionality during disturbances. However, it is not possible to back up the entire grid, much less all individual grid assets. In recent years, several devastating natural disasters have struck with great force, causing blackouts on a large scale and putting people and civil functions at risk. Therefore, new methods of improving grid resilience, limiting the spread of blackouts, and providing provisions for the rapid recovery of power grids are needed.
