Synthesis and feedback on the distribution and parallelization of FMI-CS-based co-simulations with the DACCOSIM platform

Abstract

A co-simulation applied to Smart Grids consists of grouping in the same setting models of physical components (among other electrical ones) and models of control units (including communication devices). Combining these models needs to use a generic and robust co-simulation environment instead of developing a specific one. In this context, we developed the DACCOSIM 2017 co-simulation platform based on FMI-CS (Functional Mock-up Interface for CoSimulation) standard to simulate the physical components of a Smart Grid. These components represent the most CPU-consuming part of the co-simulation. However, the tasks of FMI-CS-based applications (FMUs) are exposed as heterogeneous gray boxes with no information concerning their computation and communication volumes. Moreover, all these FMUs frequently communicate with each other by sending a lot of small messages. Consequently, the deployment of an FMI-CS based co-simulation on a distributed architecture is a complex task carried out by DACCOSIM 2017. This paper introduces the development of DACCOSIM-2017, and its experiment on distributed architectures.
