Power systems are evolving from centralized power grid structures to a network of intelligent microgrids (MGs) that can share power more independently. The interconnection between these MGs, forming the networked MGs (NMGs), will increase the power system's stability and expand its capabilities. However, a critical concern that necessitates sophisticated management strategies for voltage stabilization across the microgrids is the optimal and effective power sharing between renewable resources and energy storage devices. This paper introduces a decentralized energy management system (EMS) based on primary and secondary control levels for a system of NMGs. In the primary control level, the local controller controls the local sources within each microgrid to satisfy the load demand, the standard operating limits of sources, and the charging/discharging processes of local Energy Storage Systems (ESSs). The secondary control level will only interact when the load demand increases, or the general load connected to a common bus goes beyond a particular value. The decision will determine each MG's contribution according to their available capacities. Several study cases were created to test and verify the proposed EMS with different load demands. The simulation results supported by the hardware-in-the-loop implementation emphasize the efficacy of the proposed EMS.
