Missions

Energy flexible buildings can support the integration of renewable energy sources in the national energy mix by modulating their energy use. Modulating the heating energy use of new and existing buildings could provide 10 to 20 GW of flexible load in France. Despite a large potential identified, a number of issues prevents the deployment of this technology: communication, privacy, cost-effectiveness, control and reliability of the response.
The ANR project CLEF (Control strategies for Large scale aggregation of Energy Flexible buildings) focusses on the last two issues and will test indirect control strategies to maximise the flexibility potential and coordinate the response of energy flexible buildings. The use of an indirect controller will ensure that the objective of matching production and demand is achieved at the aggregated level, though allowing some degrees of freedom at the building scale. However, the main challenge of indirect controller is to get a reliable estimation of the capacity available, in order to trade the capacity on the electricity market. The case study for this project is the Atlantech low carbon district, located in La Rochelle. The project started in January 2018 and will last for 3 years. The project coordinator is the Laboratory of Engineering Science for Environment (LaSIE, La Rochelle) and partners from G2Elab (Grenoble) will bring their expertise in the modelling of electrical networks. Further information: http://lasie.univ-larochelle.fr/2018-2021-CLEF-ANR.
In order to contribute to this project, the laboratory is looking for a young researcher to develop the control of energy flexible buildings at district scale.

Activities

The research work will build upon the results obtained during the first two years of the project. The modelling of wet appliances and heating flexibility was developed taking into account the behavior of occupants and their acceptability towards flexibility. As a result, these models reflect the diversity and the stochastic behavior of occupants. A first case study was developed on the Atlantech district. The first results showed the possibility of using a price signal to control a group of buildings. Further research is needed to take into account different types of signals and assess the robustness of the control strategy.
The post-doctoral researcher will therefore work on the case-study of Villeneuve-les-Salines in order to:
- evaluate the robustness of neighborhood control, using black box models. The robustness will be tested with regard to the size of the district, the behavior of the occupants, the climate and flexibility scenarios;
- evaluate the influence of energy renovation on the flexibility potential of the neighborhood. As Villeneuve-les-Salines is a neighborhood under renovation, it will be interesting to take into account the influence of a reduced heating demand.
In addition to the development of models and control strategies, dissemination missions are expected such as:
- interaction with the project's scientific partners (in particular G2Elab and CSTB);
- the promotion of results through participation to conferences;
- production of scientific articles.

Skills

Candidates should have a PhD degree in Science. We are looking for a candidate who has knowledge in the field of modelling, building physics, control and optimisation. Experience in programming is required (e.g. Python). The candidate must master English language with proficiency, and basic knowledge of French language would be appreciated. Finally, the candidate should be curious and autonomous.

Work Context

The researcher will be located in the laboratory LaSIE, which is a mixed research group CNRS and La Rochelle University (UMR 7356). The research unit brings together a broad spectrum of skills with integrated approaches from the atomic scale to the material, the building and its environment at different time and space scales. The researcher will work under the responsibility of an associate professor and together with a young researcher. The researcher will be integrated to the research group Buildings and Sustainable Cities with the laboratory LaSIE.
The CNRS is in charge of the administrative and financial management of the project ANR CLEF.

Constraints and risks

Travels in France or abroad for meetings or conferences can be expected.
