An open-source framework for formal specification and simulation of electrical energy systems

摘要

Electrical energy systems (EESs) are systems which consume, generate, distribute and store energy at various scales. This paper presents a modeling and simulation framework that uses principles borrowed from the system-level simulation of digital systems and extends them to the case of EESs. The framework relies on open-source standards such as SystemC (and its Analog and Mixed-Signal extensions) for simulation, and IP-XACT for interface definition. The paper extends the IP-XACT standard with the formal definition of the interfaces of the typical components of an EESs. Then, it proposes a methodology to seamlessly plug such components into the simulation framework using the power configuration information contained in the IP-XACT descriptions. Simulations show that the proposed approach provides accuracy comparable to Matlab/Simulink results, with higher modularity and faster simulation times.
