Cooperation of TSO and DSOs
 In case of (n-1)- security violations in the
EHV-grid due to a trip of sevral lines or the
outage of a power plant TSO and DSO
collaborate to manage the incident. TSO and
DSOs operate measures according to internal
procedures.

Responsibilities of TSO & DSOs in the
interconnected grid
• SO monitoring the overall system
• GRTE Responsibility for Security
of supply
• Generators on TSO-Level
• Support of industrial
customers through
decreasing / increasing
load
• End user can be
disconnected (load
shedding)
