Challenges and Opportunities in Emergency Management of Electric Power System Blackout

With the development of industrialization and informatization, modern society is highly dependent on energy. Electric power system is fundamental for social production and daily life. Especially in urban areas, electric power network has been a key infrastructure of the lifeline, and its failure will probably paralyze the whole city. On the other hand, as population growth and urbanization, the demand for electricity is overwhelmingly increasing. Electric power network is getting larger and more complex. Meanwhile, modern electric power network is unprecedented vulnerable and modern society is faced with higher blackout risk. In order to effectively prevent blackout risk and rapidly response the blackout accident, emergency management of electric power system are responsible for preparedness, mitigation, response, and recovery of its failure. Blackout is one of the most severe accidents in electric power system failure, and is paid great attention all the time. In recent decades, many techniques have been developed for effective prevention and control of blackout. This paper analyzes the core requirements and major challenges of prevention and response of blackout. And then, some potential advanced techniques on planning, monitoring and early-warning, emergency response, etc. are introduced in view of latest research progress.
