Abstract: The usage of renewable sources increasing day by day this trend faces challenges in the reliable operation and control. Parallel connected in DC micro grid dc-dc converters are the main issues related to are flowing current and load current sharing. But for load current sharing droop control method is common technique. In dc grid voltage poor current sharing and drop are main drawbacks of conventional droop method. A component of standardized current sharing distinction and misfortunes in the yield side of the converters a Fuzzy rationale control of legitimacy called droop Record (DI) is utilized to improve the execution of dc micro grid. In between the converters the current sharing and circulating current difference minimizes by using an immediate fundamental resistance R droop. Control strategy using droop index is developed and compare with conventional droop control (PID) method validate its existing FLC results by MATLAB/ Simulink model.
