Abstract

Large electrical transmission networks are susceptible to undergo very large blackouts due to cascading failures. In this work we show how segmenting a power system using high-voltage direct-current lines can reduce the risk of blackouts. The method consists in controlling the power flowing through certain lines during cascading failures in order to minimize the load shed of each blackout. Such control can be implemented, for instance, using HVDC lines. As a result, the segmented grids have a substantially lower risk of blackouts than the original network. The control method is shown to work efficiently if the network is segmented in zones of similar size.

Keywords: grid resilience, power transmission grid, HVDC lines, grid fragmentation, blackout risk control
