Blackouts are among the main threats to the security of electric power systems. Cascading failures are known as the most important agent for creating blackouts. Transmission lines are the basic equipment of power networks whose outage can make subsequent cascading outages. In this paper, based on the application of decision tree, a new approach is proposed for an online identification of critical lines with the potential for triggering cascading failure. A trained decision tree is able to estimate the brittleness of network and, based on that, the operator will be able to change operating conditions. To this end, at first, required data for decision tree are prepared through the introduction of appropriate indicators and based on the associated blackout in a wide range of conditions including load level, load-generation patterns and network structures. Next, with a training decision tree, an algorithm for identification of critical lines and of network brittleness in blackout is proposed. To implement the proposed approach, The New England 39-bus test system has been employed.
