Experimental Validation of the Suitability of Virtualization-Based Replication for Fault Tolerance in Real-Time Control of Electric Grids

Jean-Yves Le Boudec, Wajeb Saab, Maaz Mashood Mohiuddin

Real-time control systems (RTCSs) perform complex control and require low response times. They typically use third-party software libraries and are deployed on generic hardware, which suffer from delay faults that can cause serious damage. To improve avail ...

A Prediction-Error Covariance Estimator for Adaptive Kalman Filtering in Step-Varying Processes: Application to Power-System State Estimation

Mario Paolone, Jean-Yves Le Boudec, Sidi-Rachid Cherkaoui, Lorenzo Zanni

In this paper, we present a new method for the estimation of the prediction-error covariances of a Kalman filter (KF), which is suitable for step-varying processes. The method uses a series of past innovations (i.e., the difference between the upcoming mea ...

Time-Synchronization Attack Detection in Unbalanced Three-Phase Systems

Jean-Yves Le Boudec, Mario Paolone, Marguerite Marie Nathalie Delcourt

Phasor measurement units (PMU) rely on an accurate time-synchronization to phase-align the phasors and timestamp the voltage and current phasor measurements. Among the symmetrical components computed from the phasors in three-phase systems, the standard pr ...

iPRP: Parallel Redundancy Protocol for IP Networks

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Maaz Mashood Mohiuddin, Miroslav Popovic

Reliable packet delivery within stringent delay constraints is of primal importance to industrial processes with hard real-time constraints, such as electrical grid monitoring. Because retransmission and coding techniques counteract the delay requirements, ...

AC OPF in radial distribution networks – Part II: An augmented Lagrangian-based OPF algorithm, distributable via primal decomposition

Mario Paolone, Jean-Yves Le Boudec, Dan-Cristian Tomozei, Konstantina Christakou

In the first part of this two-part paper we show that the branch-flow convexification of the OPF problem is not exact and that the ADMM-based decomposition of the OPF fails to converge in specific scenarios. Therefore, there is a need to develop algorithms ...

Ordering Events Based on Intentionality in Cyber-Physical Systems

Jean-Yves Le Boudec, Simon Bliudze, Wajeb Saab, Maaz Mashood Mohiuddin

We consider cyber-physical systems (CPSs) comprising a central controller that might be replicated for high-reliability, and one or more process agents. The controller receives measurements from process agents, causing it to compute and issue setpoints tha ...

Deficit Round-Robin: A Second Network Calculus Analysis

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

Deficit Round-Robin (DRR) is a widespread scheduling algorithm that provides fair queueing with variable-length packets. Bounds on worst-case delays obtained with DRR were found by Boyer et al. They used a rigorous network calculus approach and characteriz ...

Interleaved Weighted Round-Robin: A Network Calculus Analysis

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

Weighted Round-Robin (WRR) is often used, due to its simplicity, for scheduling packets or tasks. With WRR, a number of packets equal to the weight allocated to a flow can be served consecutively, which leads to a bursty service. Interleaved Weighted Round ...

Stability of a Stochastic Model for Demand-Response

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We study the stability of a Markovian model of electricity production and consumption that incorporates production volatility due to renewables and uncertainty about actual demand versus planned production. We assume that the energy producer targets a fixe ...

Compound Admittance Matrix Estimation of Three-phase Untransposed Power Distribution Grids using Synchrophasor Measurements

Mario Paolone, Jean-Yves Le Boudec, Fabrizio Sossan, Rahul Kumar Gupta

The paper considers the problem of estimating the parameters of the compound admittance matrix of three-phase untransposed low-and medium-voltage electrical distribution networks using synchrophasor measurements from phasor measurement units (PMUs). The wo ...

Empirical Performance Evaluation of Data Dissemination Mechanisms for Spot Applications

Jean-Yves Le Boudec, Alexandre Fawal, Adel Aziz

We evaluate, by measurements on a real testbed, the performance of networking services required for spot applications. We call a “spot application” an application for smartphones (such as “Ad-hoc Flash Sales”) that disseminates information in a local neigh ...

Understanding the simulation of mobility models with Palm calculus

Jean-Yves Le Boudec

The simulation of mobility models such as the random waypoint often cause subtle problems, for example the decay of average speed as the simulation progresses, a difference between the long term distribution of nodes and the initial one, and sometimes the ...

Mean Field Asymptotic of Markov Decision Evolutionary Games and Teams

Jean-Yves Le Boudec

We introduce Markov Decision Evolutionary Games with N players, in which each individual in a large population interacts with other randomly selected players. The states and actions of each player in an interaction together determine the instantaneous payo ...

A composable method for real-time control of active distribution networks with explicit power set points. Part I: Framework

Mario Paolone, Jean-Yves Le Boudec, Lorenzo Enrique Reyes Chamorro, Andrey Bernstein

The conventional approach for the control of distribution networks, in the presence of active generationand/or controllable loads and storage, involves a combination of both frequency and voltage regulation atdifferent time scales. With the increased penet ...

Satisfiability of Elastic Demand in the Smart Grid

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We study a stochastic model of electricity production and consumption where appliances are adaptive and adjust their consumption to the available production, by delaying their demand and possibly using batteries. The model incorporates production volatilit ...

Energy Consumption Comparison Between Macro-Micro and Public Femto Deployment in a Plausible LTE Network

Jean-Yves Le Boudec, Ramin Khalili, Miroslav Popovic

We study the energy consumptions of two strategies that increase the capacity of an LTE network: (1) the deployment of redundant macro and micro base stations by the operator at locations where the traffic is high, and (2) the deployment of publicly access ...

Efficient and Accurate Handling of Periodic Flows in Time-Sensitive Networks

Jean-Yves Le Boudec, Seyed Mohammadhossein Tabatabaee

Total Flow Analysis (TFA) is a method for the worst-case analysis of time-sensitive networks. It uses service curve characterizations of the network nodes and arrival curves of flows at their sources; for tractability, the latter are often taken to be line ...

A Theory of Traffic Regulators for Deterministic Networks With Application to Interleaved Regulators

Jean-Yves Le Boudec

We introduce Pi-regulation, a new definition of traffic regulation which extends both the arrival curves of network calculus and Chang's max-plus g-regulation, and also includes new types of regulation, such as packet rate limitations. We provide a new exa ...
