ČEPS Control Centre

Real-time operation of the transmission system is controlled and managed from the ČEPS Control Centre which is equipped with automated control systems conforming to European reliability and quality standards concerning the support of real-time dispatch control. The main ČEPS Control Centre is situated in Prague with a backup Control Centre located in Ostrava.

Dispatch control system

The dispatch control system provides support for the dispatcher both in standard situations and when forced to cope with large system failures. The control system allows the remote control of all the substations within the transmission system. A further function of the control system involves the automatic balancing of electricity demand with generation whilst complying with the schedule of exports from and imports to the Czech Republic. The control system provides the dispatcher with support for the management of power flows and voltage within the transmission system. The dispatcher, prior to deciding on what action to take, for example the tripping of a power line, can execute simulation calculations which provide him with information on the impact of the intended action on other system elements. The control system even suggests solutions for problematic situations. When a certain power line is overloaded, the control system recommends the reconfiguration of the network or the redispatching of generating plants.

 

Dispatchers, their responsibilities and partners

Dispatchers are responsible for maintaining the balance between electricity supply and demand in real time, maintaining TS transmission capability both in normal and exceptional circumstances and for tackling emergency situations.

Dispatch control comprises the following:

  • Scheduled events in compliance with day-ahead operational planning;
  • Frequency control and power balance control;
  • Coordination of supply to nodal areas; 
  • Management of the activation of purchased ancillary services;
  • Utilisation of the electricity balancing market;
  • Purchase of regulation energy and the use of emergency assistance from abroad;
  • Voltage and reactive power control;
  • Monitoring the transmission system;
  • Tackling emergency situations within the TS;
  • Operational coordination with neighbouring transmission system operators (TSOs);
  • Detection of bottlenecks;
  • Remote control of TS facilities; 
  • Use of predictor models for TS operation;
  • Utilisation of the more sophisticated functions of the dispatch control system, such as network calculations, redispatching, reconfiguration, contingency analysis etc.;
  • Maintaining operational records and documentation on all events including failures;
  • Evaluation of events and failure records; 
  • Execution of network calculations;
  • Execution of tests and
  • Collection, processing and archiving of data from the transmission system.

 

Such action is taken via the dispatch control system, in cooperation with partners at directly controlled and/or cooperating facilities.

 

ČEPS dispatcher partners consist of the following:

  • Dispatchers in power generator control rooms or power plant personnel;
  • Distribution system dispatchers;
  • Dispatchers of neighbouring transmission system operators (TSOs);
  • Duty staff at locally controlled ČEPS substations and other ČEPS permanent duty personnel and
  • Trading partners providing regulation energy supply from/to other countries.

 

Highly professional and well-trained staff are of vital importance for the quality of dispatch control. They are expected to efficiently manage both the standard operation of the transmission system and unforeseen abnormal situations or system failures. All staff are required to undergo a specially designed training programme involving the use of both ČEPS’s own and foreign dispatcher training simulators.
