摘要
This paper presents theoretical issues about CIM （common information model） and CGMES （common grid model exchange standard）, which will allow the exchange of data bases for power flow, short circuit and dynamics at ENTSO-E （European network for transport system operators for electricity） level. Grid model exchange is a complex process covering a variety of use cases, which include the exchange of equipment information, topology information, information on power system state variables, steady state hypothesis information. CGMES is an ENTSO-E standard that follows the CIM guidelines of IEC （International Electrotechnical Commission） TC57/WG13 in order to comply with the requirements of the European network codes. There are mentioned in the paper the challenges of implementing CIM and CGMES in Transelectrica for the planning cases.
