Safety in RL

[Webbah]

• Generate function to calculate condensed state-space matrices and compare to Matlab and python solution
  

• compare polytope and feasible set solutions from, e.g., https://github.com/JuliaPolyhedra/Polyhedra.jl to matlab MPT3 and Python

Proof of concept:
Delivers the same results for a known (P10) parameter setting) then Matlab and python do.

Voltage:
Matlab:

Julia:

Current:
Matlab:

Remaining problems:

volume calculation of projected polyhedron (eliminate(poly, [4, 5])) gives 0 in 3 dimensions - why?

• Similar problem? Incorrect volume calculation when H-rep contains redundant inequalities JuliaPolyhedra/Polyhedra.jl#249

Maybe problem with polyheron definition on our side?
But the same polyhedron prjected to 2 dimensions has a volume

Next steps:

• Include safeguard into ElectricGrid framework

Proof of concept ready which can be used in future work to integrate the safeguard into the toolbox
