Hi Jubeyer, MATPOWER does not include a distributed power flow or OPF mechanism to implement the approach you describe. The simplest way is to solve it was one big system.
And yes, making sure that each island has it’s own reference bus should be sufficient to allow MATPOWER to solve a case with islands, assuming the power balance in each island is feasible.
