In a context of growing societal awareness on the carbon footprint and the changing energy landscape, we need to rethink the architecture of future energy systems using new dedicated approaches. Technology advances have shown the relevance of a smart operation of multienergy cyber-physical systems (ME-CPS) requiring a strong cooperation between all players. However, in practice, the different assets that make up ME-CPS are operated by independent entities with different objectives and perspectives in mind. A new methodology is introduced that puts the stakeholders at the center of the design process by assuming that the system will be correctly designed and operated if all stakeholders reach a common agreement using formal contracts, which can be simulated for verification and validation before signature. Models are used to structure the relationships between stakeholders at all stages of the systems lifecycle: formal contracts are derived from high-level goals and are verified using “digital twins” that include requirement models and behavioral models. This new method was applied within a research project at EDF Lab to coordinate stakeholders for the renovation of a district to make it greener and smarter. Two scenarios were simulated revealing disagreements between stakeholders, and that satisfying ambitious key performance indicators (KPIs) is not an easy task requiring careful cooperation between actors.
