Towards an open case study for modeling and simulation of multi-energy systems at a district level

  • genre: break-out-group
  • title: Towards an open case study for modeling and simulation of multi-energy systems at a district level (2 hrs)
  • presenter: @mathieu-vallee @Pimprenelle
  • description:

This breakout group aims at sharing an open case study designed for analyzing and comparing various energy systems alternatives at the level of a district, city neighborhood, or industrial site.

At this level, a wide range of decisions can be investigated regarding the choice of energy supply, storage, and distribution networks (including district heating and cooling).

Although similar case studies are investigated in many scientific works, there is a consensus that the field is lagging behind in establishing shared standards, as well as open data, case studies, and benchmarks to facilitate the analysis and comparison of solutions [1].

The breakout group aims at gathering practitioners in energy system modeling interested in establishing such reference solutions.

We will in particular enable participants to experiment with an Open case study currently in development [2–4], to provide feedback on the initiative as well as ideas for future development and relevant other works / code.

The case study considers a complete analysis, from the generation of load profiles (using open source alternatives), the pre-design of system architectures (based on LP/MILP optimization [2]), to the fine tuning of model predictive control using detailed physical models and co-simulation (based on the FMU standard, as well as Modelica, Matlab/Simulink, EnergyPlus modeling [3–4]).

The outcome of the workshop could be in establishing new collaborations for further development/variants of the case study, as well as collective authoring of a paper on the topic.

  • background:

Mathieu Vallée is a researcher at CEA Liten, working on district heating networks and multi-energy systems at district level for the past ten years.

He is an active participant in the International Energy Agency working group on District Heating and Cooling, and a co-author of the Guidebook for the Digitalisation of District Heating [1].

The activities proposed in the breakout group are related to the conclusion of this work regarding the lack of shared standards, data, and benchmarks.

This work is partially supported by the PEPR TASE HyMES project, as well as by internal projects at CEA.

Hi Mathieu,

thank you for proposing the topic, I would be really happy to participate in this breakout group. We want to look into gathering existing tools and methods and bring them into workflows, currently also with a focus on urban scale energy systems focusing on geothermal integration (that’s why I suggested the breakout group about granularity and reusability of tools/workflows and data, New project - new tools?! How granular should our tools and data processing workflows be to allow for reusability?).

So @etienne.cuisinier, in case both suggestions would be accepted (and if there is enough room for all the participants I guess) it would be really nice, if these two groups would not be in parallel.

Thanks! :slight_smile:


Thanks, I agree that it would be great to attend both breakout groups, i.e. that they are not at the same time :slight_smile:

Basically, the pypsa community set excellent standards for large scale energy systems, transferring this knowledge to the local scale ones would be really good, looking forward to it!
