Recently, the power utilization rate of the distribution line(D/L) has reached utility’s limit due to the gird connection of distributed generation(DG) based on renewable energy. Also, the problem of reducing power grid reliability is caused by frequent fluctuations of DG. To solve this problem, a digital grid power router(DGPR) is proposed to increase the grid connection rate of DGs. In this study, a control model was developed to enable real-time power supply by applying a digital grid for power exchange and using a back to back(BTB) bidirectional power conversion system. The proposed system can improve the power utilization rate of D/L. Also, the power grid is not affected by changes in the output of DG because it enables asynchronous gird connection. In this paper, a design method and control model for the digital grid power router are presented considering the multi microgrid(MG). Finally, the effects of load sharing and power utilization rate improvement are verified using PSIM.
