Modelling TSO-DSO coordination: The value of distributed flexible resources to the power system

Challenge and objective

  • TSO-DSO interaction is mainly based on a uni-directional flow of information (from TSO to DSO).
  • The resources in the distribution systems are not utilized fully in overall power system operations.
  • Limited information in existing literature how the coordination of the TSO-DSO can and should be optimized.
  • Limited insights to the potential value coordination may bring to the overall power system operations.

Work performed

  • Optimization of the power system operation through modelling TSO-DSO coordination, where flexibility is provided by distributed energy resources located in the distribution systems.
  • The optimization problem is modelled as deterministic mixed integer linear programs with unit commitment and economic dispatch.
  • Case studies: 1) Top-down, 2) Coordinated TSO-DSO problem.

Significant results

  • The total costs of power system operations are reduced when distributed flexible resources are incorporated under a joint coordination framework

Impact for distribution system innovation

  • Reduced costs when including flexible resources in the operation of the power system (case result).
