The decarbonisation of energy systems is one of the main challenges of our century. Finding the optimal technological mix to achieve that goal is a major concern for policy and decision makers alike. These problems are known as energy system planning and sizing and are often tackled by Mixed Integer Linear Programming (MILP). In order [...]
The research positions are about combining modelling, simulation, optimisation, and machine learning techniques in order to investigate several technical, economic and regulatory aspects induced by major upcoming changes in energy (and in particular, electricity) generation, transmission, distribution and consumption in the context of the Energy transition. In particular, we are looking to fill several positions [...]
Download the paper Summary: Active network management (ANM) of electricity distribution networks include many complex stochastic sequential optimization problems. These problems need to be solved for integrating renewable energies and distributed storage into future electrical grids. In this work, we introduce Gym-ANM, a framework for designing reinforcement learning (RL) environments that model ANM tasks in [...]
Decarbonising sectors such as aviation, heating and industry has proved difficult via direct electrification. Hence, the synthesis of carbon-neutral fuels and feedstocks from renewable electricity has received much attention in recent years. However, in European countries such as Belgium, the theoretical amount of renewable electricity that may be produced is known to be insufficient to [...]
The topic of sector coupling and the role it may play in the energy transition has recently received a great deal of attention in European energy policy circles. In particular, power-to-gas technologies, which enable the production of hydrogen via water electrolysis as well as the synthesis of methane via the hydrogenation of carbon dioxide (the [...]
Download the research paper Retailers and major consumers of electricity generally purchase a critical percentage of their estimated electricity needs years ahead on the forward markets. This long-term electricity procurement task consists of determining when to buy electricity so that the resulting energy cost is minimised, and the forecast consumption is covered. This decision-making problem [...]
Download the research paper This research paper presents a novel deep reinforcement learning (DRL) solution to the decision-making problem behind algorithmic trading in the stock markets: selecting the appropriate trading action (buy, hold or sell shares) without human intervention. Naturally, the core objective is to achieve an appreciable profit while efficiently mitigating the trading risk. [...]
Download the research paper This paper addresses a key issue in the context of the Energy Transition: the computation of trading strategies for valorizing storage units in markets with large renewable energy integration. In particular, we focus on (short-term) intra-day markets and propose a reinforcement learning-based approach for computing well-performing strategies. The first part of [...]
#coronavirus #quefaire #médecins J'ai posé la question suivante à plusieurs médecins impliqués activement dans la lutte contre le coronavirus : « Quelles seraient les actions qu'il faudrait mettre en place pour rendre la crise du coronavirus gérable, sans provoquer un effondrement économique du pays (i.e., sans bloquer tout le pays et fermer les entreprises) ». Tous [...]
Disclaimer : ce billet n’est pas écrit par un médecin ou un épidémiologiste mais juste par un scientifique spécialisé dans le domaine de la prise de décisions qui a déjà halluciné en voyant le corps médical manquer de masques de protection et qui ne veut pas que le même problème se cause avec les respirateurs.
