Monetarization of the Feasible Operation Region of Active Distribution Grids Based on a Cost-Optimal Flexibility Disaggregation

Hierarchical grid control strategies are an appropriate design concept for the coordination of future transmission system operator (TSO) and distribution (DSO) interactions. approaches based on aggregation decentralized ancillary service potentials, represented by converter-coupled, communicable active reactive power flexibility providing units (FPU, e.g. wind turbines) at vertical TSO/DSO interfaces. The resulting PQ-polygon made available DSO a potential request flexibilities TSO is called feasible operation region (FOR). A monetarization FOR necessary implementation as operational degree freedom within control. In context local global market, this article presents approach cost structure using metadata from population methods. At market free bids FPUs stakeholders assumed. Within method multiple FPU polygons single bus aggregated reduction search space dimensions. Thereby, main contribution proposed cost-optimal disaggregation demand to mixed integer linear program. can be simply adapted DSO/DSO-interactions regarding hierarchical multi-level strategies.
