“…The LNCMI being a public research large instrument, its data and operation can be used as a representative use case for the waste heat recovery of electro-intensive industrial processes. Various studies have been carried out for the LNCMI waste heat recovery project: ▪ Planning laboratory experiments under environmental, economic or social constraints [5] ▪ Studying the flexibility of the LNCMI consumption profiles based on the identification of typical experiments [6] ▪ Multi-actor optimisation applied to the LNCMI waste heat recovery project [7] ▪ Studying the influence of the thermo-hydraulics of the LNCMI electromagnet cooling system on the LNCMI economic and environmental balance [8] ▪ Optimisation based on energy and exergy criteria [9,10] ▪ Developing open science on the LNCMI use case [11] These studies enabled to address various typical issues for waste heat recovery, applied to the LNCMI use case. Regarding the flexibility of the LNCMI experimental planning, and therefore of waste heat production, lessons learned point to the great difficulty in categorising the LNCMI experiments.…”

The French National Laboratory for High Magnetic Fields (LNCMI) provides high magnetic fields for an international community of users. On the site of Grenoble DC electricity is used to feed dedicated high power electro-magnets to produce steady magnetic fields. The magnets electrical consumption is fully dissipated as heat at variable temperatures. An ongoing project for the LNCMI electro-intensive installation analyses the opportunities for waste heat recovery into the nearby district heating network. Recent studies have pointed out energy recoveries of the order of 20% considering waste heat at 35 °C heat pumped to 85 °C and a thermal storage. One of the main reasons for this low recovery rate is the temporal mismatch between the LNCMI's activities and the district's residential heat needs. From 2020, the LNCMI has signed a new electricity contract that provides more flexibility to the high field experiment planning. Two strategies are explored to improve the waste heat recovery energy and exergy rates. Firstly, the rescheduling of the LNCMI planning of experiments in order to mitigate the temporal mismatch. Secondly, management of the cooling loops of the process to adjust waste heat at relevant temperatures. The energy analysis accounts for recovered heat quantity, while the exergy analysis accounts for the major sources of irreversibility within the LNCMI's processes. MILP optimisation problem formulation and solving proved these two strategies to be energy and exergy efficient for the LNCMI waste heat recovery. This work offers promising research and operational perspectives for flexible energy systems optimal management with both energy and exergy criteria.

Energy modelling is key in order to face the challenges of energy transition. There is a wide variety of modelling tools, depending on their purpose or study phase. This article summarises their main characteristics and highlights ones that are relevant when it comes to the preliminary design of energy studies at district scale. It introduces OMEGAlpes, a multi-carrier energy modelling tool to support stakeholders in the preliminary design of district-scale energy systems. OMEGAlpes is a Mixed-Integer Linear Programming (MILP) model generation tool for optimisation. It aims at making energy models accessible and understandable through its open-source development and the integration of energy stakeholders and their areas of responsibility into the models. A library of use cases developed with OMEGAlpes is presented and enables the presentation of past, current, and future development with the tool, opening the way for future developments and collaborations.
