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).
