Abstract

The control strategy of solar, wind, battery that connected with bi-directional DC to DC converter are used for grid connected power flow management. Generally all sources of produce the power that should satisfy the load demand without scarifies our basic needs. The power can be acquired from different source and should manage the power flow to the all places in the horizontal level. The surplus power is injected to the grid and the battery should charge from grid, it can be used for latter when it required. A half bridge boost converter coupled with transformer is utilized to collect the power from wind, meanwhile a bi-directional buck-boost converter is utilized to collect the power from solar and battery charging/discharging. AC power is fed to AC load through single phase full bridge bidirectional converter and this helps to communication with grid. The proposed method that reduces the number of switches components losses and mainly the power conversion stage. The simulation results are obtained by using MATLAB/Simulink that shows the performance of control strategy of power flow management in different modes.
