|Abstract:||The present power system is established on the principle of alternating power but there has been an increase in DC loads due to on-going revolution in electronics industry. A solution to eliminate multiple rectification processes is DC micorgrid. AC power converts to DC when entering the DC micro-grid using a high-efficiency rectifier. The DC microgrid considered in the project includes Photovoltaic system, Battery storage and AC grid connected bidirectional rectifier. The topology used for rectifier operation is a three phase two-stage design, with a boost rectifier providing power factor correction at the input to the first stage and a bidirectional dc-dc converter assembling the second stage providing power management for DC microgrid. The bidirectional converter is capable of handling the power flow to load in the condition of mismatch between power generated from PV system and the power required from the load. To validate the operation characteristics the system is extensively simulated in MATLAB/Simulink.|
