In DC microgrid, dynamic variation in source power, load demand and response of energy storage devices can cause imbalance in the DC bus voltage, therefore it is required to use proper power management system to address the dynamic variation in the DC microgrid. Present study is based on the power sharing between the multiple PV-battery systems. Main aim to distribute the power between multiple battery units on the basis of respective state of charge (SOC). Voltage droop control methodology can control the power output of the converters on the basis of SOC of different batteries. The key is to modify the droop resistance of the DC-DC converter according to SOC of battery during charging/discharging processes [1].
