Optimal Experiment Design for AC Power Systems Admittance Estimation
Xu Du, Alexander Engelmann, Yuning Jiang +2
The integration of renewables into electrical grids calls for the development of tailored control schemes which in turn require reliable grid models. In many cases, the grid topolo…
Feasibility vs. Optimality in Distributed AC OPF - A Case Study Considering ADMM and ALADIN
Alexander Engelmann, Timm Faulwasser
This paper investigates the role of feasible initial guesses and large consensus-violation penalization in distributed optimization for Optimal Power Flow (OPF) problems. Specifica…
Decomposition of non-convex optimization via bi-level distributed ALADIN
Alexander Engelmann, Yuning Jiang, Boris Houska +1
Decentralized optimization algorithms are important in different contexts, such as distributed optimal power flow or distributed model predictive control, as they avoid central coo…
Distributed State Estimation for AC Power Systems using Gauss-Newton ALADIN
Xu Du, Alexander Engelmann, Yuning Jiang +2
This paper proposes a structure exploiting algorithm for solving non-convex power system state estimation problems in distributed fashion. Because the power flow equations in large…
