The recent evolution in technology and lifestyle has been led to a dramatic increase in electricity demand so that the local communities are encountered with challenges of huge initial costs, and sustainable extension to a national grid. Here in this paper, a DC microgrid cluster with three small areas (A, B and C) is proposed. Control and power stability of small-scale electrical system using renewable resources is a big challenge. In this study, the operation of DC microgrid and behavior of the system at different operating conditions is evaluated under different condition of the solar radiation and temperature changes for specific time periods. The DC Converters with PI control strategies are integrated to control the system performance and load-power balancing. The DC bus voltage level is employed as an information carrier for controller to maintain operation stability, improve efficiency, and enhance the redundancy of a system. At the meanwhile, the Maximum Power Point Trucking Incremental Conductance (MPPT-IC) algorithm is applied to maximize the efficiency and regulate the output voltage of the PV system to desired DC bus voltage. The PV arrays with battery and bidirectional converter are simulated to overcome the intermittency problems of PV outputs. Some typical operation modes are simulated using MATLABR /Simulink to confirm the proposed model preference compared to the literature.
