run
#
It is common conduct to analyse energy system optimisation models for multiple scenarios for a variety of reasons, e.g. assessing their sensitivity towards changing the temporal and/or geographical resolution or investigating how investment changes as more ambitious greenhouse-gas emission reduction targets are applied.
The run
section is used for running and storing scenarios with different configurations which are not covered by wildcards. It determines the path at which resources, networks and results are stored. Therefore the user can run different configurations within the same directory.
run:
name: "Default" # use this to keep track of runs with different settings
disable_progressbar: false # set to true to disable the progressbar
shared_resources: false # set to true to share the default resources across runs
shared_cutouts: true # set to true to share the default cutout(s) across runs
validation: false # set to true to run back-casting plots

The scenario
section is used for setting the wildcards and defining planning horizon settings. All configurations within this section are described in wildcards with the exception of planning_horizons and foresight.
Planning horizons determines which year of future demand forecast to use for your planning model. If you leave planning_horizons:
empty, historical demand will be set according to snapshots

clustering
#
When clustering aggregation_zones
defines the region boundaries which will be respected through the clustering process; State boarders, balancing authority regions, or REeDs shapes. This feature is important for imposing constraints (opts
) which are defined over specific regions. For example, the data included in the model on interface transfer capacities are prepared for REeDs shapes but not states and BA regions. Moving forward we plan to use REeDs shapes as our default however we will maintain States and BA regions as well.
Each clustering and interconnection option will have a different number of minimum nodes which can be clustered to, an error will be thrown in cluster_network
notifying you of that number if you have selected a value too low.
Cleaned and labeled REeDs Shapes are pulled from this github repository: https://github.com/pandaanson/NYU-law-work

=– operations_only |
bool |
{‘true’,’false’} |
Overrides p_nom_extendible for other configurations and forces solution of operations only simulations. Use with co2 opt limit 1.0. |
=– load_shedding |
bool/float |
{‘true’,’false’, float} |
Add generators with very high marginal cost to simulate load shedding and avoid problem infeasibilities. If load shedding is a float, it denotes the marginal cost in $/kWh. |
=– clip_p_max_pu |
p.u. |
float |
To avoid too small values in the renewables` per-unit availability time series values below this threshold are set to zero. |
=– noisy_costs |
bool |
{‘true’,’false’} |
Add random noise to marginal cost of generators by \(\mathcal{U}(0.009,0,011)\) and capital cost of lines and links by \(\mathcal{U}(0.09,0,11)\). |
=– skip_iterations |
bool |
{‘true’,’false’} |
Skip iterating, do not update impedances of branches. Defaults to true. |
=– rolling_horizon |
bool |
{‘true’,’false’} |
Whether to optimize the network in a rolling horizon manner, where the snapshot range is split into slices of size horizon which are solved consecutively. |
=– seed |
int |
Random seed for increased deterministic behaviour. |

– |
int |
Maximum number of solving iterations in between which resistance and reactence ( |
=– transmission_losses |
int |
[0-9] |
Add piecewise linear approximation of transmission losses based on n tangents. Defaults to 0, which means losses are ignored. |
=– linearized_unit_commitment |
bool |
{‘true’,’false’} |
Whether to optimise using the linearized unit commitment formulation. |
=– horizon |
int |
Number of snapshots to consider in each iteration. Defaults to 100. |
