Enabling Modular Simulation of Hybrid Power Plants by Pre-Defined Interfaces for FMU

Hybrid power plants combine energy production, storage, and consumption into a single power plant, providing more flexibility in power generation and utilisation, leading to increased capacity factors. These complex systems include components from different engineering domains, which interact with each other and require interdisciplinary teams for development. This presents a challenge in system modelling: how can we model hybrid power plants modularly with repetitive components for control and operational research? In this study, we present a set of predefined model interfaces, which are suited for the application in modelling of hybrid power plants. Our proposed modelling framework supports the development of reusable simulation models, and makes the coupling dependencies between models clear. The interfaces can be applied to static or dynamic simulation models, which can be combined to a full system model in a co-simulation setup. In this way, the full system modelling is handled in a graph-based approach, which leads to an efficient scenario generation. The approach provides a guideline for model developers of large-scale systems to create modular components for co-simulation.
