 * Added method to iteratively reinforce a grid in case the power flow analysis does not always converge `#353 <https://github.com/openego/eDisGo/pull/353>`_
 * Added method to aggregate LV grid buses to station bus secondary side `#353 <https://github.com/openego/eDisGo/pull/353>`_
 * Added option to run reinforcement with reduced number of time steps `#379 <https://github.com/openego/eDisGo/pull/379>`_
+* Added a new reinforcement method that separate lv grids when the overloading is very high `#380 <https://github.com/openego/eDisGo/pull/380>`_
