Bridging Continuous-time LQR and Reinforcement Learning via Gradient Flow of the Bellman Error
Armin Gießler, Albertus Johannes Malan, Sören Hohmann
In this paper, we present a novel method for computing the optimal feedback gain of the infinite-horizon Linear Quadratic Regulator (LQR) problem via an ordinary differential equat…
Passivation of Clustered DC Microgrids with Non-Monotone Loads
Albertus Johannes Malan, Joel Ferguson, Michele Cucuzzella +2
In this paper, we consider the problem of voltage stability in DC networks containing uncertain loads with non-monotone incremental impedances and where the steady-state power avai…
Passivity-based economic ports for optimal operation of networked DC microgrids
Pol Jané-Soneira, Albertus J. Malan, Ionela Prodan +1
In this paper, we introduce the novel concept of economic ports, allowing modular and distributed optimal operation of networked microgrids. Firstly, we design a novel price-based…
A Unifying Passivity-Based Framework for Pressure and Volume Flow Rate Control in District Heating Networks
Felix Strehle, Juan E. Machado, Michele Cucuzzella +3
A fundamental precondition for the secure and efficient operation of district heating networks (DHNs) is a stable hydraulic behavior. However, the ongoing transition towards a sust…
On MPC-based Strategies for Optimal Voltage References in DC Microgrids
Pol Jané-Soneira, Ionela Prodan, Albertus Johannes Malan +1
Modern power systems are characterized by low inertia and fast voltage dynamics due to the increase of sources connecting via power electronics and the removal of large traditional…
Port-Hamiltonian Modelling for Analysis and Control of Gas Networks
Albertus J. Malan, Lukas Rausche, Felix Strehle +1
In this paper, we present finite-dimensional port-Hamiltonian system (PHS) models of a gas pipeline and a network comprising several pipelines for the purpose of control design and…
Passivity-based power sharing and voltage regulation in DC microgrids with unactuated buses
Albertus Johannes Malan, Pol Jané-Soniera, Felix Strehle +1
In this paper, we propose a novel four-stage distributed controller for a DC microgrid that achieves power sharing and average voltage regulation for the voltages at actuated and u…
A Unified Passivity-Based Framework for Control of Modular Islanded AC Microgrids
Felix Strehle, Pulkit Nahata, Albertus Johannes Malan +2
Voltage and frequency control in an islanded AC microgrid (ImGs) amount to stabilizing an a priori unknown ImG equilibrium induced by loads and changes in topology. This paper puts…
Passivity Conditions for Plug-and-Play Operation of Nonlinear Static AC Loads
Felix Strehle, Albertus Johannes Malan, Stefan Krebs +1
The complexity arising in AC microgrids from multiple interacting distributed generation units (DGUs) with intermittent supply behavior requires local voltage-source inverters (VSI…
A Scalable Port-Hamiltonian Approach to Plug-and-Play Voltage Stabilization in DC Microgrids
Felix Strehle, Martin Pfeifer, Albertus Johannes Malan +2
One of the major challenges of voltage stabilization in converter-based DC microgrids are the multiple interacting units displaying intermittent supply behavior. In this paper, we…
