Abstract
With the deepening of the interdependent of power and communication network components in smart grid, the critical links of smart grid increase. It is one of crux tasks for the smart grid operators how to accurately and quickly identify the critical links of smart grid under interdependent. Aiming at the traditional method of identifying critical links without considering the electrical interdependent characteristics of network nodes, this paper proposed a power network model which combines electrical interdependent and physical topology connection. Then based on this, a new algorithm of N-K critical links identification strategy based on tabu search is proposed. Simulation results show that the algorithm has high accuracy and fast identification speed, so it is more suitable for the identification of high-order critical links in large smart grid.
