Hierarchy of Power System Computing Cloud and Its Application on On-line Parallel Analysis of Power Network

KEYWORD: cloud computing, power system, on-line analysis, parallel computing, distributed com- munication ABSTRACT: In this paper, the online analysis framework based on cloud computing is presented, and the numerical calculation types of the power system is summarized. A collaborative computing model is presented on the basis of the analysis and comparison of parallel computing model and dis- tributed computing model. This model is a parallel numerical model which support distributed com- munication, intermediate data transmission and unified monitoring. It realized the loose integration of the data cloud and the model cloud, achieves the requirements of the integrated computing. Finally, we apply the computing cloud architecture to state estimation and static contingency analysis which have the typical parallel and distributed computing mode. The practical performance can meet the requirements of the future scheduling model for online analysis and calculation.
