Dispatching and control cloud (DCC) is an important part of the “three clouds” planning of State Grid Corporation of China. Aiming at the characteristics of hierarchical deployment design, which combines unification and distribution of dispatching and control cloud, basic architecture of infrastructure as a service (IaaS) layer for dispatching and control cloud is designed, which is combined with the bi-level deployment system framework of leading nodes for national dispatching and control center-regional power grid dispatching and control center and provincial collaborative nodes, based on the concept of cloud computing, and oriented to power grid regulation business. The virtualization (sharing and dynamic deployment) of hardware resources, standardization of data and service-oriented application of dispatching and control cloud platform are realized. On the other hand, the technologies such as resource virtualization of servers and storages, domain name system, load balance, read-write separation etc. are introduced into IaaS layer architecture, which provides basic support for dispatching and control cloud nodes to adopt dual-site mode, and it realizes that each node of the cloud can provide external services and remote active-active application at the business level at the same time.
