Supplementary data for "An initial assessment of the value of Allam Cycle power plants with liquid oxygen storage in future GB electricity system"

The code for the Unit Commitment & Economic Dispatch model that was used in this work is available at: https://gist.github.com/vitali87/20688c161d7b5ad598b5d52b524f4585 Sample output data can be found in the "Example Outputs.zip" file. This corresponds to the case outlined in the article that simulates a system with 5 Allam Cycle plants without Liquid Oxygen Storage, for the winter test week. To run the UCED model: Download "UC AIMMS Allam Cycle Model" code from the github and save as an AIMMS project file. Save the file in a folder that contains all the necessary input datasets, found in the "Universal Inputs for UCED Model.zip" file, and the example outputs, found in the "Example Outputs.zip" file, which are to be overwritten. Do not change the name of the input or output files. Open the project and execute the following procedures: "Main Initialisation" - to initialise the problem "Read from Excell" - to read data from the input files "Main Execution" - to begin running the problem Once the run is complete, execute "Run External Procedure" to overwrite the output files with the new data. To change the test week: Open "Demand Profiles" in 'sets' and change the set definition. Enter "C1" for the winter week and "C21" for the summer week. Another week can alternatively be selected. For example, entering "C45" would allow the model to run with the weather and demand data from the 45th week in the year 2010. Save and close the set. To change the number of plants in the system: Open "PCCSGenerators" in 'sets' and change the set definition. To run with 5 Post Combustion Capture plants, end the list of generators after plant number 5 by commenting the remaining plants. This is done by using "!" after the 5th plant name in the string. Then save and close the set. Repeat the above step for the "ACGenerators" and "AirSeparationUnits" sets, to change the number of Allam Cycle plants in the system. To add or remove oxygen storage capability from the Allam Cycle plants: Open the "Main Initialisation" procedure. To run the model without oxygen storage: make sure the following command is stated: "AC_ASU_coupled := 0;" save and close the procedure To run the model with oxygen storage: make sure the following is command is stated: "AC_ASU_coupled := 1;" make sure that the number, 'X', of "map_AC_to_ASU('Gas_CCS_AC_X') := 'ASU_X';" commands that are active matches the number of active Allam Cycle plants in the model save and close the procedure.
