Towards grid-aware multi-period flexibility aggregation - A constrained zonotope approach
Maurice Raetsch, MaÃsa Beraldo Bandeira, Christian Rehtanz +2
Aggregation schemes provide a means to reduce the computational complexity of power system operation by reducing the number of devices that are considered individually. This can be…
Flexibility aggregation via set projection for distribution grids with multiple interconnections
MaÃsa Beraldo Bandeira, Alexander Engelmann, Timm Faulwasser
With the increasing number of flexible energy devices in distribution grids, coordination between Transmission System Operators (TSOs) and Distribution System Operators (DSOs) beco…
Decentralized Real-Time Iterations for Distributed NMPC
Gösta Stomberg, Alexander Engelmann, Moritz Diehl +1
This article presents a Real-Time Iteration (RTI) scheme for distributed Nonlinear Model Predictive Control (NMPC). The scheme transfers the well-known RTI approach, a key enabler…
Decentralized non-convex optimization via bi-level SQP and ADMM
Gösta Stomberg, Alexander Engelmann, Timm Faulwasser
Decentralized non-convex optimization is important in many problems of practical relevance. Existing decentralized methods, however, typically either lack convergence guarantees fo…
Complexity Reduction for TSO-DSO Coordination: Flexibility Aggregation vs. Distributed Optimization
MaÃsa Beraldo Bandeira, Alexander Engelmann, Timm Faulwasser
The increasing number of flexible devices and distributed energy resources in power grids renders the coordination of transmission and distribution systems increasingly complex. In…
Large problems are not necessarily hard: A case study on distributed NMPC paying off
Gösta Stomberg, Maurice Raetsch, Alexander Engelmann +1
A key motivation in the development of Distributed Model Predictive Control (DMPC) is to accelerate centralized Model Predictive Control (MPC) for large-scale systems. DMPC has the…
