Transparent Access Architecture for Intelligent Dispatching and Control System

With the employment of the necessary information and communication technologies (ICTs) infrastructures, the smart grid evolves into a complex and large-scale cyberphysical system (CPS). Massive interacting components challenge the traditional data exchange mode. In order to meet the interaction requirements between intelligent substations and control center, the data service architecture for wide-area transparent access is proposed based on the general service protocol for electric power system. Then the key issue related to location transparency is discussed in terms of cross-domain service discovery as well as the service status analysis for ensuring the capabilities of wide-area services. Finally, the prototype of transparent access is implemented.
