Architecture of Data Access Based on Power Dispatch Control Cloud

The data synchronization between all the regional dispatching system under the dispatch control center and power dispatch control cloud has been realized. The data information from each region such as real-time data, manipulate data, model data and graph data firstly is sent to the communication server for this region. Besides, the communication server sends this data to the dispatch control cloud center after some processing. In order to obtain the resource from cloud center, the workstations in each region have to access cloud center remotely. However, most process in man-machine remote access adopts client/server architecture, which affects the security of data access. To solve this problem and provide data proxy service in cloud center, a new architecture of data access based on power dispatch control cloud is proposed in this paper. The architecture of data access is a client-proxy-proxy-server architecture, which can not only ensure remote workstation accessing its own resource from the cloud center, but also ensure it obtaining resource of other regions from the cloud center with not switching the platform environment of smart grid dispatching and control system.
