Attribution Mechanisms for Ancillary Service Costs Induced by Variability in Power Delivery

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Nicolas Gabriel Gast

The increased penetration of renewable energy sources in existing power systems has led to necessary developments in electricity market mechanisms. Most importantly, renewable energy generation is increasingly made accountable for deviations between schedu ...

Optimal Generation and Storage Scheduling in the Presence of Renewable Forecast Uncertainties

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Nicolas Gabriel Gast

The increase in the penetration of wind in the current energy mix is hindered by its high volatility and poor predictability. These shortcomings lead to energy loss and increased deployment of fast-ramping generators. The use of energy storage compensates ...

Decentralized list scheduling

Nicolas Gabriel Gast, Denis Trystram

Classical list scheduling is a very popular and efficient technique for scheduling jobs for parallel and distributed platforms. It is inherently centralized. However, with the increasing number of processors, the cost for managing a single centralized list ...

Impact of Storage on the Efficiency and Prices in Real-Time Electricity Markets

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Nicolas Gabriel Gast

We study the effect of energy-storage systems in dynamic real-time electricity markets. We consider that demand and renewable generation are stochastic, that real-time production is affected by ramping constraints, and that market players seek to selfishly ...

MPTCP Is Not Pareto-Optimal: Performance Issues and a Possible Solution

Jean-Yves Le Boudec, Ramin Khalili, Nicolas Gabriel Gast, Miroslav Popovic

Multipath TCP (MPTCP) has been proposed recently as a mechanism for transparently supporting multiple connections to the application layer. It is under discussion at the IETF. We nevertheless demonstrate that the current MPTCP suffers from two problems: P1 ...

A Tighter Analysis of Work Stealing

Nicolas Gabriel Gast, Denis Trystram

Classical list scheduling is a very popular and efficient technique for scheduling jobs in parallel platforms. However, with the increasing number of processors, the cost for managing a single centralized list becomes prohibitive. The objective of this wor ...
