This paper proposes a new method for transient stability analysis in terms of measuring critical clearing time using grid-computing technology. Grid computing is a highly developed system for jointly solving collaborative complex problems; those are required to solve in limited time and therefore they need high performance computing. Probabilistic transient stability analysis is one such application,...
Dynamic security region (DSR) gives system engineers systematic and global information about the feasible operation region in power injection space. This paper is a result of an investigation into the use of DSR concept and its effective application in power systems. It particularly concerns with developing a software-based tool for the dynamic security assessment in the online operation environment...
In our previous studies, it has been demonstrated that the boundary of transient stability can be approximated by hyper planes (HPs) in power injection space over quite large range. In this paper, an effective method to compute such HP of large scale power systems is proposed. Based on coherence identification of generators for a given fault, the proposed method first reduces the original system to...
