Timeseries reduction |
|||
timeseries_method |
[elmod] |
elmod |
Chooses the timeseries reduction method. Currently, only elmod is implemented |
elmod_nthhour |
[integer] |
484 |
Defined the step-size for the timeseries reduction algorithm. Good choices include 784, 484, 244, 122, 73, 25. Lower numbers will lead to more time slices and more computational requirements |
elmod_starthour |
[integer] |
8 |
Determines the start-hour of the timeseries reduction algorithm |
elmod_dunkelflaute |
[0,1] |
0 |
Enables / disables injection of an artificial “Dunkelflaute” into the timeseries |
Data input/output |
|||
switch_test_data_load |
[0,1] |
0 |
If enabled, the code will just perform a test loading of all data and terminate before the equations are constructed |
switch_only_load_gdx |
[0,1] |
0 |
If enabled, the model will just read in the data in .gdx format and not attempt to read from the Excel file |
switch_unixPath |
[0,1] |
0 |

switch_read_data_long |
[0,1] |
1 |
Determines the data structure, the codes assumes to read. 1 assumes tables in long format, 0 assumes tables in wide format |
switch_write_output |
[gdx,csv,xls] |
gdx |
Type of output files to be created. For single runs, csv or xls is recommended. If multiple runs should be compared, using .gdx and then merging it with the script in the results folder is recommended |
switch_only_write_results |
[0,1] |
0 |
Reads in a result gdx file and outputs the results as e.g. xls without re-computation |
Technical settings |
|||
solver |
[lp solver] |
cplex |
Choice of LP solver for the model |
threads |
[integer] |
6 |
Number of threads to be used. Can also be 0 (all available threads) or an offset (e.g. -2 will use all but two available threads) |
Debugging |
|||
switch_investLimit |
[0,1] |
1 |
Enables / disables “smoothing constraints” that make results more realistic. Only disable for debugging |
switch_infeasibility_tech |
[0,1] |
0 |
Enables / disables the infeasibility technologies that can provide unmet demand at very high cost. Only enable for debugging if model is infeasible |
switch_base_year_bounds |
[0,1] |
1 |
Enables / disables the base year calibration |
switch_base_year_bounds_debugging |
[0,1] |
0 |
Enables / disables a slack for the base year calibration. Only enable for debugging |
Features / functionality options |
|||
switch_ccs |
[0,1] |
1 |
Enables / disables Carbon Capture and Storage (CCS) in the model |
switch_ramping |
[0,1] |
0 |
Enables / disables ramping requirements for technologies |
switch_short_term_storage |
[0,1] |
1 |
Chooses the kind of storage formulation. For elmod-timeseries, 1 is required |
switch_all_regions |
[0,1] |
1 |
If set to 1, the model will consider all regions, if set to 0, only the first 4-5 regions will be considered. This is for testing purposes only |
switch_aggregate_region |
[0,1] |
0 |
If set to 1, the model will aggregate all regions into one single region. For calibration purposes only |
switch_intertemporal |
[0,1] |
0 |
If set to 1, the model will consider age-appropriate efficiencies of technologies, but at increased computational complexity |
switch_weighted_emissions |
[0,1] |
1 |
If set to 1, emissions will be weighted between two modeled years to determine the overall emissions (relevant for emission budget calculations) |
set_symmetric_transmission |
[share,0-1] |
0.9 |
Determines the build-out of electricity transmission lines. 0 means the model can completely freely decide, a 1 would mean full symmetric build-out |
switch_hydrogen_blending_share |
[share,0-1] |
1 |
The amount of hydrogen allowed in natural gas pipelines (as a share) |
set_storagelevelstart_up |

Peaking constraint options |

set_peaking_slack |

set_peaking_res_cf |
