Linear Optimization Based Distribution Grid Flexibility Aggregation Augmented With OLTC Operational Flexibilities

Majumdar, Neelotpal; Sarstedt, Marcel; Klub, Leonard; Hofmann, Lutz (New York, NY : IEEE, 2022)

Ancillary services e.g., voltage control, congestion management and frequency control, require to be compensated increasingly from the Distributed Energy Resources (DERs). DERs are predominantly wind and photo-voltaic power ...
Monetarization of the Feasible Operation Region of Active Distribution Grids Based on a Cost-Optimal Flexibility Disaggregation

Sarstedt, Marcel; Hofmann, Lutz (New York, NY : IEEE, 2022)

Hierarchical grid control strategies are an appropriate design concept for the coordination of future transmission system operator (TSO) and distribution system operator (DSO) interactions. Hierarchical approaches are based ...
Survey and Comparison of Optimization-Based Aggregation Methods for the Determination of the Flexibility Potentials at Vertical System Interconnections

Sarstedt, Marcel; Kluß, Leonard; Gerster, Johannes; Meldau, Tobias; Hofmann, Lutz (Basel : MDPI, 2021)

The aggregation of operational active and reactive power flexibilities as the feasible operation region (FOR) is a main component of a hierarchical multi-voltage-level grid control as well as the cooperation of transmission ...
