Research on the Security Technologies of Power Grid EMS Based on SOA

This article analyzes the accidents of power grid in some domestic region to discuss the security problems existing in the power grid Energy Management Systems (EMS). Combined with the security requirements of EMS, the method of improving EMS security based on SOA is proposed and the involving key technologies are studied as follows: the loosely coupled EMS based on SOA, the graded and modularity security configuration, the management of security configuration based on Concurrent Version System (CVS) and the mirror of Real-Time Databases (RTD) based on cloud computing. All the above technologies proposed in this paper greatly improve the security of EMS.
