Spatial Characterization of the Dynamic Response of Frequencies Utilizing Structural Partition Procedure for Large-Scale Power System.

The aim of this paper is to present an algorithm for analysing the actual spatial characterization of the dynamic responses of frequencies for large-scale power system. Based on the distribution feature of disturbance power, the measure of interaction (MI) is employed to analyse and quantify the strength of connection among the busses and generation units. The MI takes into account the interconnection constraints among network structure and parameters. In particular, only the network parameters are used in the proposed structural partition procedure. Case Studies carried out on the IEEE 68-bus system are presented to demonstrate the application and effectiveness of the technique developed. Investigations show that the spatial characterization of the dynamic responses of frequencies can be accurately obtained with the procedure, independent of fault location and the size of disturbance, since the proposed technique is based on the structural feature of the system.
