Suggestions are super welcome. I will give it a go when having a few free days.

Hi @AnasAlgarei and @pz-max @ekatef thanks for this example! Fabian and I went through it. We think **Load shedding** and **Load shifting** are ready with small adjustments, and we have...

@pz-max @FabianHofmann elastic demand can be modeled in one-step optimization. For that one needs (i) to rewrite objective to social welfare optimization and (ii) represent price via affine term [a+b*x],...

The key problem for studies with elastic demand is parametrization. We can do econometrics to estimate the demand elasticity to price in a certain region for a given commodity as...

@coroa yes, there are many studies. For example, [Labandeira et al. 2017](https://doi.org/10.1016/j.enpol.2017.01.002) survey 428 papers that use various econometric techniques to evaluate energy demand elasticity to price. They also groupby...

update: there is an ongoing restructuring process in PyPSA with the introduction of the component class (https://github.com/PyPSA/PyPSA/pull/1075) and a component xarray view (https://github.com/PyPSA/PyPSA/pull/1076) and the coming update of the optimization...

Did you test that this actually speeds up the branch-and-bound alg?

I kept thinking about this issue tonight and looked through the background math [(section 4.4 here)](https://doi.org/10.1016/j.apenergy.2022.118859), code for the losses function (incl. versions before/after optimization module rewrite in https://github.com/PyPSA/PyPSA/pull/1154), and...

### Context PyPSA has a function that approximates quadratic power losses using piecewise linear constraints. It creates tangent segments to the quadratic loss curve to model the relationship between power...
