Comprehensive planning of multiple microgrids with self-healing consideration

This paper explores the comprehensive planning methods of multiple microgrids which considering its self-healing ability in sizing and siting stage. The evaluation models of the system self-healing ability were discussed, and then system planning models were established. The complicated planning problem was divided into three parts, and the sizing part with economic and self-healing consideration was intensively discussed. In order to solve the complicated combinatorial model, the Benders Decomposition and Primal-Dual Interior Point Method were used. Simulation results on the modified IEEE 37 node test system show that the proposed methods are effective.
