Dispatch Control

Dispatch control is carried out by the ČEPS Control Centre aimed, at all times, at meeting the Company’s basic mission, i.e. to ensure the secure and reliable operation of the Czech power system.

 The dispatch control of the transmission system comprises:

  • operational planning;
  • real-time control and
  • operational evaluation.

 

Obligations and rights relating to dispatch control

TSO obligations, responsibilities and rights are set out in EU Directives and Regulations as well as binding rules associated in particular with ENTSO-E membership. According to the Multi-lateral Agreement signed on 1 June 2005 by UCTE (now ENTSO-E) members, the Operation Handbook is considered a key document and is legally binding for all member TSOs. The rules contained in the Operation Handbook have been incorporated into the Czech Energy Act (Act 458/2000) and other Czech energy legislation including Regulations and the Grid Code which is updated annually and subsequently approved by the Energy Regulatory Office (ERÚ). The Grid Code specifies conditions for the provision of transmission and system services, rules for operational planning and real-time control, the preparation of emergency plans and certification methodology.

  

Key responsibilities relating to dispatch control

  • The dispatch control of the transmission system (TS) which comprises relevant action to be taken with regard to the TS, cooperation with electricity generators and the control centres of individual distribution systems (DSs), cooperation with neighbouring transmission system operators (TSOs) which manage the Continental European interconnected network, and the execution of contracts for electricity transfer;
  • Maintaining the balance between electricity supply and demand at all times within the Czech power system whilst respecting electricity exchange schedules agreed with neighbouring transmission system operators;
  • Ensuring reliable electricity transmission whilst maintaining electricity quality parameters at the transmission system level in real time;
  • Preventing and tackling failure and emergency situations in the TS and the analysis of such situations.

 

Real-time dispatch control tools

  • Dispatch instructions – operational and real-time instructions provided by the dispatcher;
  • Technical tools – namely the dispatch control system, telecommunications links with all directly controlled and cooperating facilities, substation control systems, protection systems including those protecting TS facilities, i.e. substations and extra-high-voltage power lines;
  • Commercial procedures – namely the activation of contracted ancillary services (AnS), the purchase of regulation energy in the balancing market or from abroad, the redispatching of generating plants etc.

 

Such tools and procedures allow both system and transmission services of the required quality to be provided at the Czech TS level.
