Voltage-sensitive distribution factors for contingency analysis and topology optimization
Maurizio Titz, Dirk Witthaut, Joost van Dijk +2
Topology optimization is a promising approach for mitigating congestion and managing changing grid conditions, but it is computationally challenging and requires approximations. Co…
Accelerated DC loadflow solver for topology optimization
Nico Westerbeck, Joost van Dijk, Jan Viebahn +2
We present a massively parallel solver that accelerates DC loadflow computations for power grid topology optimization tasks. Our approach leverages low-rank updates of the Power Tr…
Towards Efficient Multi-Objective Optimisation for Real-World Power Grid Topology Control
Yassine El Manyari, Anton R. Fuxjager, Stefan Zahlner +5
Power grid operators face increasing difficulties in the control room as the increase in energy demand and the shift to renewable energy introduce new complexities in managing cong…
Unified algebraic deviation of distribution factors in linear power flow
Joost van Dijk, Nico Westerbeck, Lars Schewe +2
Distribution factors are indispensable tools in the design and analysis of power transmission grids. Recently, they received a renewed interest in the field of topology optimizatio…
