Research on Application of SDN in Dispatching System of Power Grid

With rapid development of power grid, the accurate and centralized analysis are characteristic of the future dispatching trend in power grid, all information of dispatching system at all level need to be shared. The demand for optimization operation of dispatching data network is more and more urgent. SDN is a new flexible frame for dispatching data network that can be more flexible in controlling network flow. This paper analysis feasibility of application about SDN applied in dispatching data network, and prompt typical application scenarios. Based on SDN the new architecture of the dispatching data network is proposed for network optimization and flexible control. The service flow can be classified by more fine-grained controlling level than before. Qos of end-to-end technology and network monitoring technology is elaborated in this paper, Above all, SDN can bring broad a widely prospect of application in dispatching data network in power grid.
