reV.SAM.SAM.RevPySam

class RevPySam(meta, sam_sys_inputs, output_request, site_sys_inputs=None)

Bases: Sam

Base class for reV-SAM simulations (generation and econ).

Initialize a SAM object.

Parameters:

• meta (pd.DataFrame | pd.Series | None) – Meta data corresponding to the resource input for the single location. Should include values for latitude, longitude, elevation, and timezone. Can be None for econ runs.

• sam_sys_inputs (dict) – Site-agnostic SAM system model inputs arguments.

• output_request (list) – Requested SAM outputs (e.g., ‘cf_mean’, ‘annual_energy’, , ‘gen_profile’, ‘energy_yield’, ‘ppa_price’, ‘lcoe_fcr’).

• site_sys_inputs (dict) – Optional set of site-specific SAM system inputs to complement the site-agnostic inputs.

Methods

assign_inputs()	Assign the self.sam_sys_inputs attribute to the PySAM object.
collect_outputs(output_lookup)	Collect SAM output_request, convert timeseries outputs to UTC, and save outputs to self.outputs property.
default()	Get the executed default pysam object.
drop_leap(resource)	Drop Feb 29th from resource df with time index.
ensure_res_len(arr, time_index)	Ensure time_index has a constant time-step and only covers 365 days (no leap days).
execute()	Call the PySAM execute method.
get_sam_res(*args, **kwargs)	Get the SAM resource iterator object (single year, single file).
get_time_interval(time_index)	Get the time interval.
make_datetime(series)	Ensure that pd series is a datetime series with dt accessor
outputs_to_utc_arr()	Convert array-like SAM outputs to UTC np.ndarrays

Attributes

DIR
IGNORE_ATTRS
MODULE
attr_dict	Get the heirarchical PySAM object attribute dictionary.
input_list	Get the list of lowest level input attribute/variable names.
meta	Get meta data property.

property meta

Get meta data property.

property module

Get module property.

property site

Get the site number for this SAM simulation.

static get_sam_res(*args, **kwargs)

Get the SAM resource iterator object (single year, single file).

static drop_leap(resource)

Drop Feb 29th from resource df with time index.

Parameters:

resource (pd.DataFrame) – Resource dataframe with an index containing a pandas time index object with month and day attributes.

Returns:

resource (pd.DataFrame) – Resource dataframe with all February 29th timesteps removed.

static ensure_res_len(arr, time_index)

Ensure time_index has a constant time-step and only covers 365 days (no leap days). If not remove last day

Parameters:

• arr (ndarray) – Array to truncate if time_index has a leap day

• time_index (pandas.DatatimeIndex) – Time index associated with arr, used to check time-series frequency and number of days

Returns:

arr (ndarray) – Truncated array of data such that there are 365 days

static make_datetime(series)

Ensure that pd series is a datetime series with dt accessor

classmethod get_time_interval(time_index)

Get the time interval.

Parameters:

time_index (pd.series) – Datetime series. Must have a dt attribute to access datetime properties (added using make_datetime method).

Returns:

time_interval (int:) – This value is the number of indices over which an hour is counted. So if the timestep is 0.5 hours, time_interval is 2.

outputs_to_utc_arr()

Convert array-like SAM outputs to UTC np.ndarrays

collect_outputs(output_lookup)

Collect SAM output_request, convert timeseries outputs to UTC, and save outputs to self.outputs property.

Parameters:

output_lookup (dict) – Lookup dictionary mapping output keys to special output methods.

assign_inputs()

Assign the self.sam_sys_inputs attribute to the PySAM object.

execute()

Call the PySAM execute method. Raise SAMExecutionError if error. Include the site index if available.

property attr_dict

Get the heirarchical PySAM object attribute dictionary.

Returns:

_attr_dict (dict) –

Dictionary with:

keys: variable groups values: lowest level attribute/variable names

classmethod default()

Get the executed default pysam object.

Returns:

PySAM.GenericSystem

property input_list

Get the list of lowest level input attribute/variable names.

Returns:

_inputs (list) – List of lowest level input attributes.

property pysam

Get the pysam object.
