Most of the new technological changes in power systems are expected to take place in distribution grids. The enormous potential for distribution flexibility could meet the transmission system's needs, changing the paradigm of generator-centric energy and ancillary services provided to a demand-centric one, by placing more importance on smaller resources, such as flexible demands and electric vehicles. For unlocking such capabilities, it is essential to understand the aggregated flexibility that… Expand

Characterizing Power Support from Distribution Networks via Flexibility Area Segmentation
TLDR
A framework for characterizing and managing active distribution networks (ADNs) via flexibility area segmentation relies on combinatorial optimization models and classifies the ADN flexibility area’s segments by the number of flexible units activated and probabilities associated with units activation.

Estimating the Active and Reactive Power Flexibility Area at the TSO-DSO Interface
TLDR
This paper presents a methodology based on the solution of a set of optimization problems that estimate the flexibility ranges at the distribution and transmission system operators (TSO- DSO) boundary nodes and suggests that a higher accuracy in the TSO-DSO information exchange process can be achieved through this approach.

The challenges of estimating the impact of distributed energy resources flexibility on the TSO/DSO boundary node operating points
TLDR
The effectiveness of the proposed model has been evaluated on two test networks and the results suggest a step forward in the TSO/DSO coordination field, although further investigations to study the effect of assets with discrete control nature on the occurrence of disjoint flexibility areas should be carried.
