1		Unit	Values	Description
2	options
3	-- 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.
4	-- 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 EUR/kWh.
5	-- curtailment_mode	bool/float	{'true','false'}	Fixes the dispatch profiles of generators with time-varying p_max_pu by setting ``p_min_pu = p_max_pu`` and adds an auxiliary curtailment generator (with negative sign to absorb excess power) at every AC bus. This can speed up the solving process as the curtailment decision is aggregated into a single generator per region. Defaults to ``false``.
6	-- noisy_costs	bool	{'true','false'}	Add random noise to marginal cost of generators by :math:`\mathcal{U}(0.009,0,011)` and capital cost of lines and links by :math:`\mathcal{U}(0.09,0,11)`.
7	-- skip_iterations	bool	{'true','false'}	Skip iterating, do not update impedances of branches. Defaults to true.
8	-- rolling_horizon	bool	{'true','false'}	Switch for rule :mod:`solve_operations_network` 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. This setting has currently no effect on sector-coupled networks.
9	-- seed	--	int	Random seed for increased deterministic behaviour.
10	-- custom_extra_functionality	--	str	Path to a Python file with custom extra functionality code to be injected into the solving rules of the workflow relative to ``rules`` directory.
11	-- io_api	string	{'lp','mps','direct'}	Passed to linopy and determines the API used to communicate with the solver. With the ``'lp'`` and ``'mps'`` options linopy passes a file to the solver; with the ``'direct'`` option (only supported for HIGHS and Gurobi) linopy uses an in-memory python API resulting in better performance.
12	-- track_iterations	bool	{'true','false'}	Flag whether to store the intermediate branch capacities and objective function values are recorded for each iteration in ``network.lines['s_nom_opt_X']`` (where ``X`` labels the iteration)
13	-- min_iterations	--	int	Minimum number of solving iterations in between which resistance and reactence (``x/r``) are updated for branches according to ``s_nom_opt`` of the previous run.
14	-- max_iterations	--	int	Maximum number of solving iterations in between which resistance and reactence (``x/r``) are updated for branches according to ``s_nom_opt`` of the previous run.
15	-- transmission_losses	int	[0-9]	Add piecewise linear approximation of transmission losses based on n tangents. Defaults to 0, which means losses are ignored.
16	-- linearized_unit_commitment	bool	{'true','false'}	Whether to optimise using the linearized unit commitment formulation.
17	-- horizon	--	int	Number of snapshots to consider in each iteration. Defaults to 100.
18	-- post_discretization
19	-- -- enable	bool	{'true','false'}	Switch to enable post-discretization of the network. Disabled by default.
20	-- -- line_unit_size	MW	float	Discrete unit size of lines in MW.
21	-- -- line_threshold		float	The threshold relative to the discrete line unit size beyond which to round up to the next unit.
22	-- -- link_unit_size	MW	float	Discrete unit size of links in MW by carrier (given in dictionary style).
23	-- -- -- {carrier}
24	-- -- link_threshold		float	The threshold relative to the discrete link unit size beyond which to round up to the next unit by carrier (given in dictionary style).
25	-- -- -- {carrier}
26	agg_p_nom_limits			Configure per carrier generator nominal capacity constraints for individual countries if ``'CCL'`` is in ``{opts}`` wildcard.
27	-- agg_offwind	bool	{'true','false'}	Aggregate together all the types of offwind when writing the constraint. Default is false.
28	-- include_existing	bool	{'true','false'}	Take existing capacities into account when writing the constraint. Default is false.
29	-- file	file	path	Reference to ``.csv`` file specifying per carrier generator nominal capacity constraints for individual countries and planning horizons. Defaults to ``data/agg_p_nom_minmax.csv``.
30	constraints
31	-- CCL	bool	{'true','false'}	Add minimum and maximum levels of generator nominal capacity per carrier for individual countries. These can be specified in the file linked at ``electricity: agg_p_nom_limits`` in the configuration. File defaults to ``data/agg_p_nom_minmax.csv``.
32	-- EQ	bool/string	{'false',`n(c| )``; i.e. ``0.5``-``0.7c``}	Require each country or node to on average produce a minimal share of its total consumption itself. Example: ``EQ0.5c`` demands each country to produce on average at least 50% of its consumption; ``EQ0.5`` demands each node to produce on average at least 50% of its consumption.
33	-- BAU	bool	{'true','false'}	Add a per-``carrier`` minimal overall capacity; i.e. at least ``40GW`` of ``OCGT`` in Europe; configured in ``electricity: BAU_mincapacities``
34	-- SAFE	bool	{'true','false'}	Add a capacity reserve margin of a certain fraction above the peak demand to which renewable generators and storage do *not* contribute. Ignores network.
35	solver
36	-- name	--	One of {'gurobi', 'cplex', 'highs', 'cbc', 'glpk'}; potentially more possible	Solver to use for optimisation problems in the workflow; e.g. clustering and linear optimal power flow.
37	-- options	--	Key listed under ``solver_options``.	Link to specific parameter settings.
38	solver_options		dict	Dictionaries with solver-specific parameter settings.
39	mem	MB	int	Estimated maximum memory requirement for solving networks.
