Increasingly throughout the world, interconnected power systems are collapsing following severe disturbances that have produced system voltage instability. This paper reports that in tackling this problem, simulations on a 92 bus network have studied the consequences of losing five lines simultaneously. With no countermeasures, the disturbance caused system voltage instability which culminated in its collapse. Following the same disturbance, a series of specific countermeasures was simulated. This arrangement of measures was able to restore the grid to a secure operating state, even with the five lines still out of service.
