[docs]class DivergingPowerflow(BackendError): """ This exception indicate that the :class:`grid2op.Backend.Backend` is not able to find a valid solution to the physical _grid it represents. This divergence can be due to: - the system is not feasible: there is no solution to Kirchhoff's law given the state - the powergrid is not connected and some area of the grid do not have slack buses - there is a "voltage collapse" : the voltages are ill conditioned making the _grid un realistic. - the method to solve the powerflow fails to find a valid solution. In this case, adopting a different :class:`grid2op.Backend.Backend` might solve the problem. """ pass
