Unexpected Consequences: Global Blackout Experiences and Preventive Solutions
Power system blackouts result in complete interruption of the electricity supply to all consumers in a large area. Systems need to be planned and engineered in a way that minimizes exposure to and prevents cascading blackouts. Blackouts are caused by a sequence of cascading outages caused by a combination of multiple low-probability events (e.g., a transmission line sagging into a tree, hidden failures in equipment protection, the loss of multiple generation units because of a weather event, and aging equipment failure) occurring in an unanticipated or unintended sequence. The likelihood for power system disturbances to escalate into a large-scale cascading outage increases when the grid is already under stress. This stress can be caused by lower operational margins, overloaded equipment, and other factors, which are discussed in detail in this article.
期刊介绍:
IEEE Power & Energy Magazine is dedicated to disseminating information on all matters of interest to electric power engineers and other professionals involved in the electric power industry with a focus on advanced concepts, technologies, and practices associated with all aspects of electric power from a technical perspective in synergy with nontechnical areas such as business, environmental, and social concerns. IEEE Power & Energy Magazine keeps its readers up-to-date on the latest technological advancements, industry news, business trends and strategies, products, and publications. Important newsworthy items concerning the worldwide activities and achievements of IEEE Power & Energy Society (PES), its organizational units, and its individual members are also included.
