Update CEC module and inverter libraries for SAM 2021.12.02 #837

Description

@cpaulgilman

Postponing update of CEC module and inverter libraries to Patch 1 because of changes in data from CEC. Instructions are in private SAM-documentation repo under Developer Tools and Instructions/Wind and PV Libraries.

  1. For inverters, there are now two lists for "solar inverters" and "battery inverters." We want to include inverters from both, but need to check the two lists to see how they compare:
    a) Check that cec_hybrid library parameter works for both lists.
    b) Consider adding some SAM UI checks to give user feedback on whether a selected inverter is suitable for batteries.

  2. We no longer need the cec_type parameter because CEC has discontinued the "grid support" vs "utility interactive" classification. Requires removing cec_type from the UI forms and defaults. We could potentially use this to identify inverters from the solar inverters and battery inverters list, but I think the cec_hybrid parameter may meet that requirement.

  3. The default inverters for FOM (SMA America SC750CP-US) and BTM Commercial (SMA America STP 60-US-10) are not in the most recent CEC list -- perhaps these are older models? Need to replace with equivalent inverters and test.

  4. Module test script cec_modules_test.lk takes hours to run through the ~17,000 modules in the library. Consider modifying it to run a single time step at a couple of reference irradiance/temperature conditions instead of a complete simulation to be faster.
