Power System Simulation and Preliminary Modeling Based on the Smart Grid Core Standards

With the development of computer technology and the rapid prevalence of the Internet Power started to use computer to realize the unification and standardization. So IEC puts forward IEC 61970 specification series, which makes EMS normalize and interconnects different EMS. CIM has been defined by IEC61970 which commented by UML. Meanwhile, in order to further the support of information exchange on electricity, power industry has developed CIM / XML, which is method used XML to represent the CIM. This article briefly describes the CIM, XML and UML, the exploration of XML document in detail for expression framework is showed in the CIM class diagrams, and complete the parse of XML documents.
