Implement TDPF (temperature dependant powerflow) #40
Description
Is your feature request related to a problem? Please describe.
The methodology is described here : https://ieeexplore.ieee.org/abstract/document/8783234 and here https://ieeexplore.ieee.org/abstract/document/6555947
As well as other more standard physical variables (complex voltage at each buses of the grid) this model also outpus the temperature of the powerlines.
Describe the solution you'd like
Implementation is similar to the "multiple slack" one, basically adding some rows / columns in the jacobian to compute the powerflows.
Describe alternatives you've considered
There are no alternative yet on lightsim2grid. Some versions of pandapower (developed by @rbolgaryn), currently in development, might be available.
Additional context
Interesting for DLR and / or for better grid2op integration (having limits not only on amps by rather on line temperature)
