Piecewiselinear efficiency using fix_ratio_out_in_unit_flow?

[manuelma]

I can set up the piecewiselinear efficiency using the incremental_heat_rate parameter, however I cannot do it using fix_ratio_out_in_unit_flow. Is this intentional? I thought this feature 'duplication' was to please different worldviews, but one is more powerful than the other?

This was one of the main reasons for implementing piecewise linear heat rates. Untill then, the piecewise functionality only existed with unit_constraints (now user_constraints).

It's intentional but perhaps not ideal

Closing due to inactivity and low priority.

I did initial tests with fix_ratio_in_out_unit_flow parameters that are basic floats, timeseries of floats and arrays (piecewise linear). Those seemed to work ok, but it does not work with timeseries of arrays. I suppose I should update _has_simple_fix_ratio_unit_flow but I don't know how.

Unit tests and migration are still missing.
