Distributionally robust infinite-horizon control: from a pool of samples to the design of dependable controllers

Jean-Sébastien Hubert Brouillon, Giancarlo Ferrari Trecate, Andrea Martin

We study control of constrained linear systems with only partial statistical information about the uncertainty affecting the system dynamics and the sensor measurements. Specifically, given a finite collection of disturbance realizations drawn from a gener ...

Power grid parameter estimation without phase measurements: Theory and empirical validation

Jean-Sébastien Hubert Brouillon, Giancarlo Ferrari Trecate

Reliable integration and operation of renewable distributed energy resources requires accurate distribution grid models. However, obtaining precise models by field inspection is often prohibitively expensive, given their large scale and the ongoing nature ...

Minimal regret state estimation of time-varying systems

Jean-Sébastien Hubert Brouillon, Giancarlo Ferrari Trecate

Kalman and H-infinity filters, the most popular paradigms for linear state estimation, are designed for very specific specific noise and disturbance patterns, which may not appear in practice. State observers based on the minimization of regret measures ar ...

Maximum likelihood estimation of distribution grid topology and parameters from Smart Meter data

Jean-Sébastien Hubert Brouillon, Giancarlo Ferrari Trecate

This paper defines a Maximum Likelihood Estimator (MLE) for the admittance matrix estimation of distribution grids, utilising voltage magnitude and power measurements collected only from common, unsychronised measuring devices (Smart Meters). First, we pre ...

Bayesian Error-in-Variables Models for the Identification of Distribution Grids

Jean-Sébastien Hubert Brouillon, Giancarlo Ferrari Trecate, Pulkit Nahata

The increasing integration of renewable energy requires a good model of the existing power distribution infrastructure, represented by its admittance matrix. However, a reliable estimate may either be missing or quickly become obsolete, as distribution gri ...

Regularization for distributionally robust state estimation and prediction

Jean-Sébastien Hubert Brouillon, Giancarlo Ferrari Trecate, Florian Dörfler

The increasing availability of sensing techniques provides a great opportunity for engineers to design state estimation methods, which are optimal for the system under observation and the observed noise patterns. However, these patterns often do not fulfil ...
