Preventing large-scale blackouts in power systems under uncertainty

In modern electricity grids uncertainties only multiply. The ongoing deregulation and the expansion of renewable energy in power system worldwide require more complex control and decision making. As a result, large-scale blackouts still continue to happen. The authors deal with a topical issue: how to take the effective preventive actions given randomly changing circumstances in order to avoid power system cascading emergencies. In this paper, an intelligent viable approach is proposed to minimize the threat of large-scale blackouts under uncertainty. The proposed system can both serve the profit motive and prevent large-scale emergencies that arise from voltage instability. The developed system was tested on the modified IEEE One Area RTS-96 power system.
