In this paper the equivalent model of electric batteries is developed and implemented in MATLAB/Simulink to evaluate the terminal voltage and power variation during the battery charging and discharging periods. The concept of electric vehicle fast charging station is summarized and its detailed simulation model is designed for the integration of the electric vehicle batteries with the distribution network. Then the interactions between electric vehicle charging stations and active distribution grid with wind turbines are investigated. The focus is to examine the possibility of bi-direction power flow control capability of EV charging stations in providing the voltage support for distribution network operations to improve the fault-ride-thro ugh of adjacent wind turbines. Simulations are used to illustrate the feasibility as well as the effectiveness of the proposed control concept. Potentially such voltage support from EV charging station can be developed as ancillary services in smart distribution grid operations.
