The use of renewable sources growing day by day this trend is facing effective operation and control challenges. The key issues relating to sharing of the load current and the circulated currents are equivalent paired dc dc converter in Direct Current micro grid. A common method for sharing of the load currents is drop control the disadvantages of traditional sag system remain low recent allocation of decrease in dc voltages in the grids. A Fuzzy merit control logic called the Droop Index (DI) is used toward boost efficiency of Direct Current micro grid, in which it is a function of standardized contemporary allocation variance and fatalities on the yield adjacent of the converters. The disparity between the converters in mingling current and present sharing minimizes by the use of an immediate internal R droop resistance. Droop index control technique is developed and the modern droop control (PID) approach is contrasted with fuzzy logic validating the current FLC tests by MATLAB / Simulinkmodel.
