Further to my post above and copied from another thread……. As regards my work with the Electricity System Operator.
I was preparing the data for the Generation Scheduler Digital Twin in 1976 Day ahead planning) then running the coupled Generation Scheduling to Fuel Allocation Digital Twins from 1978 (including getting the suite to run smoothly). Then ensuring the Coupling from the Generation Scheduling to the Transmission modelling (Security and Stability) models was in place when we implemented the enhanced Scheduler Twin for Control use in 1985. Plus the coupling to the EMS Dispatch Twin process which itself was coupled to the real world metering and the real time transmission twins.
CReDo is a linked system but we also need coupling. Noting that we also had a linked Generation-Fuel optimiser in 1978 but due to computing limits we had to compromise the generation model from Time series to load duration. Which further distorts the accuracy of representing the real world Time Sequence of Generation Instruction and operation.
And I see we have CReDo for Climate resilience and the UKRI Centre for Research into Energy Demand Solutions (CREDS) initiative which has UCL running their Energy Digital Twin (ESTIMO). Although the latter is only Time series simulation and needs to be interfaced with the Infrastructure Twins, including Electricity and other Energy movement Network Design with Security and Stability models. Plus the Resources analysis, including better use of Waste (also an Infrastructure issue especially for City design).
All with Iterative coupling between DT models noting that the IEA Smart Grids Project (ISGAN) has identified the need for coupled simulations. In order to get the necessary affordable high efficiency high flexibility solution to achieve serious Emissions reduction and avoid Primary Energy Scarcity impacts.
Thank you @Stephen Browning
