Online dynamic security assessment based on grid computing architecture

On-line Dynamic Security Assessment (DSA) is a challenge computing problem. A key problem in DSA is the analysis of a large number of dynamic stability contingencies using on-line data. This paper presents a grid computing framework and application to DSA. Using advanced computing technology, we developed a real-time system dynamic security assessment tool that runs on the grid computing framework, which can enable power system operators to anticipate and prevent potential stability problems before they can lead to cascading outages. The paper also discuss how to make DSA CIM (Common Information Model) compliant that makes it easier to integrate DSA into any vendor's Energy Management System (EMS). (7 pages)
