System splitting strategy considering power system restoration [PDF]
2017 IEEE Manchester PowerTech, 2017 An Intentional Controlled Islanding (ICI) algorithm based on an exact Mixed Integer Programming Formulation (MILP) was previously proposed and tested using IEEE test systems. The proposed algorithm directly determines an islanding solution with minimal power-flow disruption for any given number of islands, while ensuring that each island contains only ...
