P2P Computing Mode and Its Application in Flow Computation

The P2P computing mode which may effectively overcome some shortages of the present sequential and parallel computing mode is applied to the large-scale power flow computation in this paper. The advantages of the P2P mode are analyzed and presented. The mathematic model and computing method is put forward and analyzed based on current-influx model. Based on current-influx method, power network is easily partitioned, and the relation among subtasks becomes weak. The mutual dispatch management in P2P are researched for the flow computation. The static and dynamic dispatch methods are adopted, which may flexibly adjust the topological structure of computing network. The dispatch arithmetic of the load-balance is studied, which may transfer high load to near computing node according to the total present computing instance. And the computing efficiency is enhanced totally. The proposed computing model and methods are implemented in IEEE 118-buses system. The computing results have approved the validity of this computing model.
