Augmentation of Generalized Multivariable Grid-Forming Control for Power Converters with Cascaded Controllers
Meng Chen, Dao Zhou, Ali Tayyebi +3
The classic design of grid-forming control strategies for power converters rely on the stringent assumption of the timescale separation between DC and AC states and their correspon…
Hybrid Angle Control and Almost Global Stability of Grid-Forming Power Converters
Ali Tayyebi, Adolfo Anta, Florian Dörfler
This paper introduces a new grid-forming control for power converters, termed hybrid angle control (HAC) that ensures the almost global closed-loop stability. HAC combines the rece…
Parametric local stability condition of a multi-converter system
Taouba Jouini, Florian Dörfler
We study local (also referred to as small-signal) stability of a network of identical DC/AC converters having a rotating degree of freedom. We develop a stability theory for a clas…
Interactions of Grid-Forming Power Converters and Synchronous Machines
Ali Tayyebi, Dominic Groß, Adolfo Anta +2
An inevitable consequence of the global power system transition towards nearly 100% renewable-based generation is the loss of conventional bulk generation by synchronous machines,…
Energy-based Stabilization of Network Flows in Multi-machine Power Systems
Catalin Arghir, Florian Dörfler
This paper considers the network flow stabilization problem in power systems and adopts an output regulation viewpoint. Building upon the structure of a heterogeneous port-Hamilton…
On Placement of Synthetic Inertia with Explicit Time-Domain Constraints
Theodor Borsche, Florian Dörfler
Rotational inertia is stabilizing the frequency of electric power systems against small and large disturbances, but it is also the cause for oscillations between generators. As mor…
Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging
John W. Simpson-Porco, Qobad Shafiee, Florian Dorfler +3
In this work we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the propose…
On Resistive Networks of Constant Power Devices
John W. Simpson-Porco, Florian Dorfler, Francesco Bullo
This brief examines the behavior of DC circuits comprised of resistively interconnected constant power devices, as may arise in DC microgrids containing micro-sources and constant…
Input-output analysis and decentralized optimal control of inter-area oscillations in power systems
Xiaofan Wu, Florian Dörfler, Mihailo R. Jovanović
Local and inter-area oscillations in bulk power systems are typically identified using spatial profiles of poorly damped modes, and they are mitigated via carefully tuned decentral…
