Volt-VAr-Watt Optimization in Four-Wire Low-Voltage Networks: Exact Nonlinear Models and Smooth Approximations - Extended Version
Sleiman Mhanna, Frederik Geth, Lucas Quiertant +1
The proliferation of distributed energy resources is increasing the prevalence of both overvoltages and undervoltages in low-voltage (LV) distribution networks. Smart inverter func…
Dynamic Network Prices for Prosumer-aware Hosting Capacity Management
Jiawei Zhang, Gregor Verbic, Frederik Geth +3
The fast uptake of distributed energy resources (DERs) presents increasing challenges for managing hosting capacity in distribution networks. Existing solutions include direct load…
Stochastic Security Constrained AC Optimal Power Flow Using General Polynomial Chaos Expansion
Ghulam Mohy-ud-din, Yunqi Wang, Rahmat Heidari +1
Addressing the uncertainty introduced by increasing renewable integration is crucial for secure power system operation, yet capturing it while preserving the full nonlinear physics…
Distribution System State and Impedance Estimation Augmented with Carson's Equations
Marta Vanin, Frederik Geth, Rahmat Heidari +1
The impedances of cables and lines used in (multi-conductor) distribution networks are usually unknown or approximated, and may lead to problematic results for any physics-based po…
