Electric vehicle integration to distribution grid ensuring quality power exchange

摘要

Now a days, Electric Vehicle (EV) integration to the distribution grid is gradually increasing and is hitting with much power quality issues. This paper presents a smart compactible integration of EV with the distribution grid assuring a quality power. Charging station is the place where an EV integrates with the grid. In this paper, works have been done for a level 3 off-board EV charging infrastructure that can employ multiple EVs which will alleviate the down-time required for vehicle charging. There is a master control to deal with the power exchange between the AC and DC bus (AC-DC Converter Control). The control of individual EV is de-centralized (DC-DC Converter Control). The proposed work looks into two different aspects of EV integration to grid a) Grid to Vehicle mode-G2V (EV charging), b) Vehicle to Grid Mode-V2G (EV discharging Mode) ie, proposing EV as a grid connected distributed generation, c) Simultaneous EV charging and discharging mode ie, G2V & V2G operations. Simulation platform is Matlab. Results show the feasibility of the proposed model during grid integration.
