【Abstract】 In order to satisfy the requirement of high efficiency description for power system model and data exchange, the model description language E is developed, It adopts object-oriented technology, is compatible with relation-oriented technology, and inherits the advantages from XML. For 100 nodes CIM model description, the efficiency of E language is 13. 6 times higher than that of XML. The E language has been successfully applied in electric power system of China.更多还原
