Leveraging second-order information for tuning of inverse optimal controllers
Taouba Jouini, Zhiyong Sun, Venkatraman Renganathan
We leverage second-order information for tuning of inverse optimal controllers for a class of discrete-time nonlinear input-affine systems. For this, we select the input penalty ma…
Grid-friendly Matching Control of Synchronous Machines by DC/AC Converters in Bulk Power Networks
Taouba Jouini
An islanded inverter-based microgrid is a collection of heterogeneous DC energy resources, e.g., photovoltaic arrays, fuel cells, and energy-storage devices, interfaced to an AC di…
On cost design in applications of optimal control
Taouba Jouini, Anders Rantzer
A new approach to feedback control design based on optimal control is proposed. Instead of expensive computations of the value function for different penalties on the states and in…
Inverse optimal control for angle stabilization in converters-based generation
Taouba Jouini, Anders Rantzer, Emma Tegling
In inverse optimal control, the optimality of a given feedback stabilizing controller is a byproduct of the choice of a meaningful, a posteriori defined, cost functional. This allo…
Grid-forming lambda-omega virtual oscillator control in converter-based power systems
Taouba Jouini, Emma Tegling, Zhiyong Sun
Inspired by the kinetics of wave phenomena in reaction-diffusion models of biological systems, we propose a novel grid-forming control strategy for control of three-phase DC/AC con…
Distributed learning for optimal allocation of synchronous and converter-based generation
Taouba Jouini, Zhiyong Sun
Motivated by the penetration of converter-based generation into the electrical grid, we revisit the classical log-linear learning algorithm for optimal allocation {of synchronous m…
Steady state characterization and frequency synchronization of a multi-converter power system on high-order manifolds
Taouba Jouini, Zhiyong Sun
We investigate the stability properties of a multi-converter power system model, defined on a high-order manifold. For this, we identify its symmetry (i.e., rotational invariance)…
Performance analysis and optimization of power systems with spatially correlated noise
Taouba Jouini, Zhiyong Sun
Based on stochastic differential equations (SDEs), we analyse the overall performance of heterogeneous power systems network, subject to spatially distributed and correlated noise…
Fully decentralized conditions for local convergence of DC/AC converter network based on matching control
Taouba Jouini, Zhiyong Sun
We investigate local convergence of identical DC/AC converters interconnected via identical resistive and inductive lines towards a synchronous equilibrium manifold. We exploit the…
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…
Grid-forming Control for Power Converters based on Matching of Synchronous Machines
Catalin Arghir, Taouba Jouini, Florian Dorfler
We consider the problem of grid-forming control of power converters in low-inertia power systems. Starting from an average-switch three-phase inverter model, we draw parallels to a…
