By increasing the penetration of distributed energy resources (DERs) and developing the microgrids (MGs) due to its implication for the existing circumstance of power system, Networked-Microgrid (NMG) approach is becoming an important issue in smart distribution grids. On the other hand, low probability but extreme events like natural disasters or the fuel interruption can threaten the grid security. For this end resiliency problem is discussed in this paper for the MMG structure of distribution network. The main objective of this chapter is to globally reach the minimum cost operation of microgrids in normal condition while meeting the adequacy in resiliency operation mode. The dispatchable unit status, energy storage and adjustable loads scheduling and the energy trade status between microgrids in each hour are evaluated with stochastic modeling of load and renewable power generations. It is of important because these microgrids have energy exchange between each other under control of energy management system (EMS) in addition of energy drawing from main grid. This can prepare an option to count on DER capacity of other microgrids in resiliency mode of system operation when the main grid is disconnected.
