Fast Parallel Newton-Raphson Power Flow Solver for Large Number of System Calculations with CPU and GPU
Zhenqi Wang, Sebastian Wende-von Berg, Martin Braun
To analyze large sets of grid states, e.g. when evaluating the impact from the uncertainties of the renewable generation with probabilistic Monte Carlo simulation or in stationary…
Evaluating Machine Learning Models for the Fast Identification of Contingency Cases
Florian Schaefer, Jan-Hendrik Menke, Martin Braun
Fast approximations of power flow results are beneficial in power system planning and live operation. In planning, millions of power flow calculations are necessary if multiple yea…
Review of Steady-State Electric Power Distribution System Datasets
Steffen Meinecke, Leon Thurner, Martin Braun
Publicly available grid datasets with electric steady-state equivalent circuit models are crucial for the development and comparison of a variety of power system simulation tools a…
Comparison of Meta-Heuristics for the Planning of Meshed Power Systems
Florian Schäfer, Jan-Hendrik Menke, Martin Braun
The power system planning task is a combinatorial optimization problem. The objective function minimizes the economic costs subject to a set of technical and operational constraint…
An efficient open-source implementation to compute the Jacobian matrix for the Newton-Raphson power flow algorithm
Florian Schäfer, Martin Braun
Power flow calculations for systems with a large number of buses, e.g. grids with multiple voltage levels, or time series based calculations result in a high computational effort.…
Vectorized Calculation of Short Circuit Currents Considering Distributed Generation - An Open Source Implementation of IEC 60909
Leon Thurner, Martin Braun
An important task in grid planning is to ensure that faults in the grid are detected and cut off without damage in any grid element. Calculating short circuit currents is therefore…
