Using pypower to model power outage in part of the grid

[Justyna Chromik]

Hello,

I am new to PyPower. 

I wanted to use Mosaik framework to model a power outage in part of the grid. Mosaik by default uses PyPower to calculate the power load equations. I thought about testing it simply by disconnecting a branch in a radial topology, so that two nodes are not connected, and therefore an entire branch is disconnected. This threw an error. I am not sure if this is because of Mosaik, or if it is because of PyPower. 

So I thought the easiest it to ask you if it is possible to calculate the power load equations knowing that part of the grid is disconnected? Or should PyPower only analyse the connected nodes? If PyPower needs to only receive the information about the connected elements, then I would need to fix it on the Mosaik side. 

Did any of you use PyPower to model a power outage?
