As a consequence of the energy transition, energy systems are moving toward more distributed architectures. This paper proposes a method to co-design today's and tomorrow's energy systems, relying on an innovative model-based engineering methodology taking account of the requirements of all stakeholders and of the spatiotemporal and physical constraints of the system. It enables the use of simulation to verify design and operational solutions against system requirements. Thus, not only solutions but also requirements need to be modelled in languages with well-defined syntax and semantics. Requirements and high-level solutions (e.g., systems architectures) may be modelled in the innovative language FORM-L (FOrmal Requirements Modeling Language), whereas detailed solutions may be modelled using behavioral languages in place such as Modelica or Anylogic. A demonstrator called PowerGrid illustrates the overall methodology on a rather complete district energy system, embedding energy production facilities, energy consumers and appropriate networks.
