A new solution architecture for online power system analysis

The current DSA system used in the dispatching control centers in China is a near real-time analysis system with response speed in the order of minutes. Based on a review of the state-of-the-art in online analysis and discussion of distributed data processing and computation architecture patterns, a new online analysis architecture is proposed. The primary goal of the new architecture is to increase the online analysis response speed to the order of seconds. A reference implementation of the proposed online analysis architecture to validate the feasibility of implementing the architecture and some performance testing results are presented.
