JSON Scripts

JSON scripts in neup-ies/simulations/json are defined as nested “dictionaries” in the following format:

PySAM_inputs

These inputs are typically either parameters useful in the Pyomo optimization that are not used within SSC or filepaths to data files that we want to extract data and set as vector/array inputs to SSC.

PySAM_outputs

These are keywords that are used within the NE2 modules to generate an .csv output file (optional).

SSC_inputs

As of Python 3.6, dictionary keys preserve order when retrieved. Therefore the ordering of entries in the SSC_inputs dictionary needs to be in a specific format.

We assume that there are data entries for each of three modules: - a Plant module (tcsmolten_salt, nuclear_tes, etc.) - a Grid module (typically grid) - a Financial module (typically single_owner)

The first entry of SSC_inputs should be:

"compute_module_0" : <SSC_module_name>,

for whatever module you are trying to simulate. All entries after that belong to the Plant module.

The next entry (after the last Plant data entry is specified) should be:

"compute_module_1" : <SSC_grid_name>,

followed by Grid-specific data entries.

Repeat the syntax for Financial module data entries.

Finally, the last entry of the SSC_inputs dictionary in the JSON script should be:

"number_compute_modules" : <N>
}

where N is the number of compute modules (typically 3). This syntax ensures that we can run the PySSCWrapper correctly for debugging.
