Multilevel cooperative on-line computing architecture under dispatching cloud

Dispatching cloud based on the concept of cloud computing provides an efficient and feasible technology solution, which in order to ensure security, stability, economic and environmental operation in the future integrated bulk grid. This paper analyzed application services mode in detail for on-line analysis in dispatching cloud, designed a multi-level cooperative on-line computing architecture, and studied the encapsulation of computing service modules. The main topic focuses on the key technologies to realize multi-level cooperative on-line computation, which include computing tasks allocation mapping mechanism, decomposition-coordination computing service bus, computing service driven engine and data interaction service mechanism, etc. Finally, the computing service diagram is developed to achieve on-line analysis service and state estimation service instance is applied to respond user's calculation request. It is a useful exploration and provides reference with a scene of carrying out collaborative operation between data cloud, model cloud and computing cloud in an efficient way.
