Piecewise interpolation in a stochastic optimization

Good afternoon,

I am linearizing the efficiency curve on an inverter with piecewise linearization.

The deterministic optimization works fine (first image). However, when I move to stochastic optimization, the interpolation (which is scenario-based) randomly picks the breakpoints of the curve, leading to an error (second image).

Do you have any idea why this happened?

Thank you in advance for your comments

  Hi Matteo,

  Are you using Gurobi PWL functionality and is the PWL function continuous (i.e. do adjacent segments meet, or are they disconnected)?
