Anti-Disaster Power Security Risk Assessment Framework and Its Application

As a kind of basic energy, electric power energy security problem is very crucial. To raise the power system stability, assess and supervise the whole power system and its inner potential risks as well as establishing the power security risk assessment system to cope with catastrophe is of great theoretical and practical importance. The paper first analyses the defects of existing power system risk assessment system. It proposes that the power security risk assessment work should adopt the mode of government and electric power enterprises collaboration. Then from the practical point of view, it establishes the new practical power system risk assessment framework that should be cooperated by both government and electric power enterprises to cope with catastrophe and prevent large area blackout in power system. The new risk assessment framework is consist of traditional stability analysis, newly developed probabilistic reliability analysis as well as the risk analysis on power system structure, technology, equipment and management aspects. At present the newly developed risk assessment framework has been applied in Guangdong province and therefore proves that the assessment system framework is scientific and practical.
