ModeliScale collaborative project brings Modelica to handle large Scale Cyber Physical Systems for the Energy industries in CATIA apps
Europe has to face a new paradigm: energy systems become more and more decentralized, they involve more actors and consumers with sometimes divergent interests. The progressive insertion of new energy production means (with renewables in particular), consumption sources (vehicles chargement) and storage technologies are modifying the architecture of these systems. In order to handle the future energy mix, there is strong need for new modeling and simulation means (ModSim) to design and combine such systems for a better definition and piloting of of their performance.
ModeliScale project aims to enable the Modelica technology to fit for the modeling & simulation of very large models of energy systems, in a multi-mode and reconfigurable context. It considers different time and space scales, multiple sources of energy production (classic and alternative), and various forms of energy transport consumption (buildings, vehicles, storage).
Today; no Modeling and Simulation language and tools has the capability to tackle large scale multi modes systems. Therefore, project aims innovative concepts to handle such systems.
Three main objectives are considered by the consortium :
• Compile and execute large scale models, up to millions of equations
• Handle multi-mode models (from switching from nominal to degraded states, dynamically re configuring according to energy demand (network management, electric vehicle charging stations) or intermittent production (eg. solar)) with a target of 2^80 combined modes and more
• Enable a proper initialization of such large scale multimode models , relying on proper convergence and/or calibration to ensure the correctness of the initial states
Several teams from Inria are working on innovative algorithms and methods, aiming at proposing a new paradigm for the modeling and simulation of cyber-physical systems in general, and energy systems in particular. Prototypes are developed in Dassault Systemes; CATIA/Dymola and CATIA 3DExperience.
Multi physics libraries will address electric, energy storage, heat networks, and buildings thanks to the support of SME’s DPS & Eurobios. The open source EDF DACCOSIM NG co-simulation tool will be enhanced. Statistical and probabilistic methods will be adapted by Phimeca to help initialize and analyze Modelica models.
Demonstrators from EDF and ENGIE major energy providers will evaluate how the current bottlenecks of large-scale simulation are overcome : the whole energy grid city of Vélizy (Paris area) is considered by EDF; while a full heat production plant and district heating network is considered by ENGIE for a Lyon suburban city (Rhone area).
Additionally, CEA Tech research center will evaluate the value related to its multi energy micro grid located in the Alps.
CATIA portfolio will be strongly enhanced with these innovations to be ahead in the field of large scale energy systems Modeling and Simulation, including Dymola technology and 3DEXPERIENCE platform systems apps.
DACCOSIM NG EDF co simulation platform will get the capability to handle simulation of very large power grids (at the city scale).
Modelica open language for systems modelling and the FMI open standard for interoperability will benefit from the project innovative enhancements of this project. Enhancement proposals will be offered to these respective communities.
New energy Modelica libraries will be prototyped for a potential go to market next phase.
Moreover, project outcomes will be generic. So both open Modelica language, FMI standard and implementations will be useful in other industrial sectors such as aeronautics, transportation, buildings and cities.
ModeliScale project is leveraging on Modelica and FMI standards.
Moreover, ModeliScale outcomes will feed these 2 standards with evolution proposals.
