For the realization of each regional autonomous system within single-phase/three-phase multi-microgrids(TP/SP MMGs)reconnected to the distribution network steadily

fleetly and orderly

a connected sequential path search algorithm applied to TP/SP MMGs which considers the time of synchronism check and stability is proposed. Based on the TP/SP MMGs graph model

the connected sequential path search problem can be transformed into a minimum spanning tree problem

and the improved Prim search algorithm is used to search the minimum tree. After the success of reconnection to the distribution network

the particle swarm optimization algorithm based on mixed integer programming is executed to centrally recover the removed minor loads

confined new energy output and electric quantity of energy storage battery. Finally

the proposed algorithm is verified by the platform of multi-microgrids with single-phase/three-phase architecture based on DIgSILENT

which proves the validity and practicability of the proposed algorithm. This work is supported by National High Technology Research and Development Program of China(863 Program)(No. 2014AA052001)and Key Laboratory of Clean Energy Technology of Guangdong Province
