Bi-Directional Power Flow Control for Three Phase Grid Tied Converters in Ev Charging Applications

The expenses associated with conventional energy have increased dramatically in recent times due to factors such as climate change, environmental degradation, and the depletion of fossil resources. Thus, there is an urgent global need to use clean, innovative energy. Worldwide, there is widespread usage of electric cars (EVs) with smart grid technologies. More and more attention has been directed into the Vehicle-to-Grid (V2G) system. The Bi-directional grid-connected AC/DC converter, which enables bilateral power transfer while satisfying grid power quality criteria, is an essential component of the V2G hybrid system. A Bi-directional Power flow control for three phase grid tied converter is presented in this study. It can offer bidirectional power transfer between EVs and the grid in addition to correcting reactive power and lowering power grid volatility. Introducing the V2G system setup and creating the mathematical model for the AC/DC converter are the first tasks. The next step is to propose an analysis of the PI control method and build a controller. D-Q-0 theory finds use in efficiently synchronising the grid and controlling ripple current in the grid current. The basis for the system simulation model is MATLAB/Simulink.
