Please check if the PR fulfills these requirements

  • CHANGELOG.md is updated
  • Docs have been added / updated if applicable
  • Any new packages have been added to the [compat] section of Project.toml
  • REopt version number is updated in Project.toml and CHANGELOG.md if merging into master (do this right before merging)
  • Tests for the changes have been added. These tests compare expected behavior and include CHP-specific regression coverage.
  • Any new REopt outputs and required inputs have been added to the corresponding Django model in the REopt API

Description of changes

This PR adds support for modeling existing CHP capacity through existing_kw and aligns CHP sizing semantics (min_kw and max_kw apply to new capacity beyond existing capacity).

Validation

  • Added CHP existing capacity regression coverage.
  • Ran CHP-focused regression suite from the test directory:
    • CHP Existing KW
    • Multiple CHPs
    • Avoid CHP Binary
    • Off-Grid CHP
    • CHP Production Factor
  • Result: all tests passed in the focused suite (36/36).
