With gradual increase in energy consumption, air pollution and global warming, the tendency to use electrical smart grid in transportation has greatly increased, resulting in great utilization of electric vehicles.The initial approach toward smart grid is AC and DC Microgrids. DC power systems are gaining an increasing interest in renewable energy applications.
In this dissertation, two distributed generators (DGs) have been merged together with a pair of batteries to form an autonomous dc microgrid.To overcome the control challenge associated with coordination of multiple battery units, load sharing between units and voltage stability in dc microgrids, a novel control strategy based on Voltage droop has been proposed.the primary control loop was established by an adaptive coltage-droop method aimed to regulate the common bus voltage and to sustain the state of charge of batteries closed to each other. The control of every units was expended with unit specific algorithm, i.e. finish of charging for batteris and maximum power point tracking (MPPT) for renewable energy sources. A small signal stability analysis for the whole range of VR has been proposed.
Performance of propoes MG in different scenarios, load demand, power generation has been simulated.The main parameters to monitor is bus voltage, output current of every single unit. For conclusion, the result has been analysed.simulations has been done in MATLAB-Simulink.
