WG C4.603 Analytical Techniques and Tools for Power Balancing Assessments

Background :

There are increasing challenges related to balancing control and management of fast reserves in power systems around the world. This is especially true in power systems and control areas that have a large penetration of wind generation. In addition, the opening to competition of new power markets has created larger variations and uncertainties in power flows that need to be managed. It is also a fact that presently there are few tools and analytical techniques readily available for the analysis of power balancing issues, ranging from secondary and tertiary generation control to the organisation of markets for balancing and reserves management.

Scope :

The main scope of this WG will be the critical assessment of existing modeling methods and tools for analyzing power balancing issues in order to provide recommendations for future developments. The main activities will include:

  • Overview of balancing control practices and balancing markets. This activity will serve as an introduction and a background for identifying the need for new analytical tools. It is expected that previous and ongoing work under study committees C1, C2, C5 and C6 can provide valuable input to this overview.
  • Review existing analytical techniques and tools for the assessment and analysis of balancing control problems.
  • Collection and description of relevant application examples.
  • Identify and describe the need for new models and tools based on existing knowledge.
  • Recommend areas for further research and development to gain new knowledge.

In this context the problem of power balancing includes all power system control and operational aspects ranging from secondary power control up to management of reserves and intra-hour power (balancing) markets. Relevant application areas for the analytical techniques and tools in question include the analysis of:

  • Secondary and tertiary control (Technical issues, LFC/AGC, utilization of HVDC-links, etc.)
  • Reserves management (how to assess power imbalances and the need for reserves)
  • Benefits and challenges with larger control areas and multi-national balancing markets.

The WG will seek to closely coordinate its activities with related ongoing work performed under study committees C1, C2, C5 and C6.
