Thanks MArk but it is iteration that is crucial as the results from one twin in each pair will affect the other which has to execute with the new data and signal the impact back  Iteration continues until convergence or major changes to the input parameters of one or both twins are identified as necessary.  i.e large scale change.

Thanks Anna, I think what you have overall is better defined as Coupled Iterating Digital Twins? – as I keep arguing.

I was running coupled Iterating Generation operation – Fuel Allocation Optimisation twins back from 1978. Industry now costs the customer @£40bn/yr.

Do we have to submit anything to continue receiving the invites to the weekly Gemini seminars. 

Noting that the existing invite has the comment.

Digital Twins can revolutionise the way our systems operate – as I know from first running the Generation Scheduling models from 1976 and getting the first one into full service in control by 1985.   Using basic Visualisation (in those days) to convince our Control Room Engineers and management.  So, getting the message across simply to the Community and wider public is needed?

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.

Thanks Joaf.  I then realised I was preparing the data for the Generation Scheduler Digital Twin in 1976 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.

We need Integrated modelling of Resources and Infrastructure with Coupled Iteration.  Especially for Energy.   Coupled Digital Twins.
The IEA Smart Grid Network (ISGAN) has done some coupled modelling and I have experience with Iterative Generation-Fuel optimisation models (albeit late 1970s)
