C2 System Operation and Control


To facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of system operation and control.  To add value to this information and knowledge by means of synthesising state of the art practices and developing recommendations.


The scope of the Study Committee covers the technical, human resource and institutional aspects and conditions needed for a secure and economic operation of existing power systems under security requirements against system disintegration, equipment damages and human in­juries.

The main areas of attention are:

  • Control and switching of objects, voltage control, frequency control by balancing generation vs demand, monitoring of loading limits and actions to avoid capacity violations (congestion management).  Reserves and emergency strategies, management of fault and restoration situations, interaction between the system and power plants.  Short term plan­ning and co-ordination of system capacity needs with maintenance of the physical assets.
  • Evaluation and benchmarking of the system performance in terms of fault frequency, interruptions, operational and maintenance efficiency, both from the technical and eco­nomical points of view.
  • Impact on system operation targets, methods and performance from new institutional structures of System Operators (TSO or ISO), regulators, market actors, trading mecha­nisms and contracted ancillary services.
  • Requirements, methods, tools (simulators) and performance indices for training of operators.
  • Development and use of power system analysis and security assessment functionalities within operational planning and the computer and telecommunication systems support­ing the control centres and the operators.


Each Study Committee oversees a number of Working Groups.
