Feature- and Structure-Preserving Network Reduction for Large-Scale Transmission Grids
Julia Sistermanns, Matthias Hotz, Dominic Hewes +2
Many countries are currently challenged with the extensive integration of renewable energy sources, which necessitates vast capacity expansion measures. These measures in turn requ…
Network-Constrained Robust Unit Commitment for Hybrid AC/DC Transmission Grids
L. P. M. I. Sampath, M. Hotz, H. B. Gooi +1
The day-ahead energy and reserve management with transmission restrictions and voltage security limits is a challenging task for large-scale power systems in the presence of real-t…
hynet: An Optimal Power Flow Framework for Hybrid AC/DC Power Systems
Matthias Hotz, Wolfgang Utschick
High-voltage direct current (HVDC) systems are increasingly incorporated into today's AC power grids, necessitating optimal power flow (OPF) tools for the analysis, planning, and o…
The Hybrid Transmission Grid Architecture: Benefits in Nodal Pricing
Matthias Hotz, Wolfgang Utschick
Recently, we proposed a capacity expansion approach for transmission grids that combines the upgrade of transmission capacity with a transition in system structure to improve grid…
Reducing the Need for New Lines in Germany's Energy Transition: The Hybrid Transmission Grid Architecture
Matthias Hotz, Irina Boiarchuk, Dominic Hewes +2
The energy transition will lead to an imbalance in electric power generation and demand along the north-south axis of Germany. To manage this imbalance, the transmission system ope…
A Hybrid Transmission Grid Architecture Enabling Efficient Optimal Power Flow
Matthias Hotz, Wolfgang Utschick
The recent rise of electricity generation based on renewable energy sources increases the demand for transmission capacity. Capacity expansion via the upgrade of transmission line…
Linearization of Time-Varying Nonlinear Systems Using A Modified Linear Iterative Method
Matthias Hotz, Christian Vogel
The linearization of nonlinear systems is an important digital enhancement technique. In this paper, a real-time capable post- and pre-linearization method for the widely applicabl…
