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,...
Development for a static voltage security assessment software package entitled power system voltage stability region (PSVSR) is presented in this paper. A novel power system stability analysis method named "security region" is utilized to develop this comprehensive software package. PSVSR has been implemented in standard C++ on Windows environment. It is constructed with three layers: user...
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...
This paper proposes to display the boundary of static voltage stability region (SVSR) in cut-set complex power space for large electrical power systems. Active and reactive power flows on the branches in the critical cut-set are utilized to construct cut-set complex power space. We discovered that the boundary of SVSR can be approximated by hyper-planes in cutset complex power space. The paper summarizes...
