Abstract

In this paper, a grid security index considering cascade tripping is proposed, and an algorithm is proposed for this index combination with the operating behavior of relay protection so as to solve the cascading tripping problem of the power system. Firstly, according to the current behavior of branch cascading tripping and the action of line current-mode backup protection, the critical state of grid cascading trip is analyzed, and it is proved that the input power of grid nodes can be used to describe the security of grid. Then, based on the relationship between the input power of nodes and the security level of power grid, a model is presented to represent the security level of power system without cascading failures under the impact of initial faults, and the model is solved by particle swarm optimization. An example proves the validity of the algorithm.
