Modelling and analysis of cascading failure in complex power networks

This thesis is dedicated to extensive studies on cascading failure modelling and analysis of complex power systems. A novel Power System Dynamic (PSD)-based Cascading Failure Simulation Platform (CFSP) is proposed, which takes into consideration PSD, load models, relay models, and automatic load shedding mechanisms. Moreover, a novel stochastic cascading failure model considering the interdependency between the cyber network and power network has been introduced. The multi-agent system and complex protection relay models are incorporated into the proposed model. Several different analytical approaches have been proposed to better understand the complex mechanisms during the cascading failure using the proposed models.
