Variable efficiency coefficient for Electrolyzer, battery and EV charger, etc.

[Alireza64z]

Some technologies such as hydrogen electrolyzers and EV chargers have a variable efficiency coefficient that cannot be fixed. However, by using a piecewise linear approximation, we can convert the nonlinear curve of the efficiency coefficient into a linear form.

I suggest the addition or modification of a parameter similar to "fix_ratio_out_in_unit_flow" that can incorporate piecewise linear steps for the coefficient. The modeling process for this parameter is similar to that of the "unit_incremental_heat_rate" parameter.

Thank you.

Hi @Alireza64z - that functionality would be nice and is in the pipeline. However, in the meantime, there is nothing preventing you using incremental_heat_rate and unit_idle_heat_rate to do the same thing
