Smart Grid Standards Based Application Integration And Security Technologies Research

With the developping of power enterprise informatization construction, a necessary technical means to ensure the forward compatibility and software reusability is integration of application systems which can meet the requirements integrations in department level and bussiness level. In the internal network of electric power enterprise current, there is composed of products provided by a number of hardware manufacturers and software vendors, in generally. These all designed at different times for various business requirement. Because of the diversification of user categories and user needs, the application system of electric power enterprises is no more expansion in a distributed environment, also it can not afford different data resources to be shared in degrees. A further increase in complexity of business may cause immeasurable and unsustainable for information sharing between different services for electric power system. The International Electric Committee established a series of standards to standardize the application integration and information exchange between systems.This topic mainly puts forward a new enterprise service bus technology to solve the application integration and information sharing, and puts forward a new access control model which ensure resources sharing security. The enterprise service bus is an integrated platform using event driven architecture and service oriented architecture solutions.This platform can make it easer that real-time data exchange in electric power enterprise with characteristics of distributed heterogeneous. This paper also proposed a new access control model which is workflow-based on service-oriented to ensure the power system resource accessed orderly and legitimately. This paper will give a solution to the integration of power system control center under the IEC standards, and it use Mule ESB to design application integration management system under workflow model with ESB access control.With the developping of enterprise service bus, this technology in power system also will be maturer, and it will provide more flexible and more efficient solutions.
