Operational coordination between TSO and DSO for control of reactive power needs to be improved to handle more distributed energy resources in the distribution grid.
The appropriate information exchange methods using Common Information Model (CIM) and Inter-Control Centre Protocol (ICCP) should be identified.
Work performed
The smartgrid lab was used to evaluate the performance impact of different levels of information exchange between TSO and DSO.
Significant results
It was found that (a subset of) the CGMES CIM profile was sufficient also for the TSO-DSO information exchange for the voltage control use case.
Nomenclature: - Common grid model exchange standard (CGMES) - Common information model (CIM)
Impact for distribution system innovation
The CGMES profile is a good starting point for the TSO-DSO information exchange.
For other use cases it may be needed to add some distribution system specific information to the profile
