Abstract
Standardization is the development tendency of information exchange among control centers.Based on the standard in IEC 61970,an information exchange model suitable for coordinated automatic voltage control(CAVC) among multi control centers is proposed.Firstly,the contents of information flow of CAVC is analyzed and the definition of coordinated control model for information exchange is given;then the common information model is extended and a standardized information model for CAVC is designed;and then based on component interface specification,a standardized information exchange interface for CAVC is designed and its architecture for information exchange as well as its information exchange procedure are given.The presented information exchange model possesses wide application prospect in the implementation of information exchange among multi CAVC control centers for future smart grids.
