Build mock objects

[rouille]

We need to instantiate a MockGrid and MockScenario objects to hopefully used modules in PostREISE

[danielolsen]

If we get the Grid from #49, and the time-series outputs from #50, then is there anything else we need to be able to make a MockScenario? Or is the remaining work to create a user-facing function that does it all, starting from a folder of outputs?

I don't think so. We might need to update our mock objects. They probably don't handle profiles

MockScenario can handle profiles just fine, via MockAnalyze: https://github.com/Breakthrough-Energy/PowerSimData/blob/develop/powersimdata/tests/mock_analyze.py#L25

Based on my most recent experience using mock objects, they could take mock profiles in the current structure. To be specific, mock scenario could take mock profiles and mock grid attributes. Example use case here.

Is MockGrid up to date? Not sure it has the model_immutables attribute?

[danielolsen]

We will need to re-process the time-series inputs so that they have the proper index and columns for the Scenario object to use when calculating things like curtailment.

Here's the status of everything I think we need for a 'full' MockScenario object representing the Switch solution:

• post-expansion Grid: done via feat: create Grid from Switch results #97, refactor: distribute branch upgrades among parallel paths #106, and feat: add storage expansion results to Grid #104 (pending)
• input profiles: done via feat: create full-dimension input profiles from Switch inputs and resulting Grid #107 (pending)
• output PF/PG: done via Feat: Expand Timepoint Data into Timeseries Data #68, feat: add helper function to extract values from matching variables #96, feat: extract pg pf from Switch results #108 (pending)
• output duals (LMP, CONGU, CONGL): not yet done (some discussion at Process output data #47)
• output storage operation (STORAGE_E, STORAGE_PG): not yet done (some discussion at Get time series of results #50).

EDIT: Besides what we are already saving in the Switch project folder, it seems that we also need as inputs:

• the temporal mapping file used to create time-series inputs to Switch
• The timepoints.csv file used to create time-series inputs to Switch

If we begin to save these files in the folder when we generate the Switch inputs (i.e. within profiles_to_switch, we save the timepoints and timestamp_to_timepoints input parameters), then I think the Switch project folder should contain all the necessary information to build a MockScenario object (excluding duals and storage time series for now), and we should be able to only ask the user 'which folder should I look into for all of the files that I need?'.

[danielolsen]

As discussed elsewhere, there may be two different use cases that the user wants. Either:

• the user wants to analyze the MockScenario as Switch saw it (i.e. temporal reduction on the input profiles)
• the user wants to use the MockScenario to perform a full time-domain production cost modeling analysis (i.e. as we would do if we created a fresh Scenario using a ChangeTable; the input profiles are not reduced)

The former is implemented via #107, the latter seems to be desired by @YifanLi86. I think this could be an option that the user selects from the main user-facing function when they pass the Switch project folder, once we have backend logic for the latter feature.

Closed via #109 and #111.
