In the transient process modeling pathway three subsets of workflows can be characterized all using HYBRID: economic analysis, grid integration, and technology deployment.
Economic Analysis: For economic analysis the models inside HYBRID are interrogated to characterize the unit performance and the missed demand that would occur as the unit operates within various markets. These values then feed into the technoeconomic analysis pathway.
Grid Integration: If the transient process models are utilized for grid integration studies, then the large-scale process models (e.g., nuclear power plants, gas turbines, thermal energy storage systems) will be used alongside either new Modelica models or FMI/FMUs (functional mock-up interfaces or functional mock-up units) to characterize and develop new IES configurations, develop control algorithms, characterize ramp rates of systems, and optimize heat/electrical flows.
Technology Deployment: The final workflow using the HYBRID repository is the screening and deployment of technology at INL using verified and validated digital twins of the INL experimental facilities. In this pathway a collaborator can virtually hook up a simulation of their technology, via FMI/FMU or a Modelica model, to test novel control algorithms, potential integration techniques, and energy flows in the laboratory on validated digital twins of the systems prior to down-selecting the technology for deployment in the field at INL. This provides a lower cost, faster, and more robust way of testing novel control strategies prior to bringing a technology into the lab to increase the system Technology Readiness Level (TRL) and to perform validation and verification analysis.
