Abstract

This paper presents the control and implementation of multifunctional electric vehicle charging station (EVCS) assisted by the wind energy conversion system (WECS) and the PV array, an energy storage battery and the grid. In an islanded mode (IM), the WECS and PV array are used to charge the vehicle and to supply the domestic equipment's connected to the EVCS in coordination with the storage battery. However, the excess power is sent back to the grid for power balance. This EVCS supports the AC as well as DC charging. To achieve the continuous charging, seamless mode transition logic is embedded into the charging station control. Apart from the regular operation of the charging, the EVCS participates in various ancillary services. The operation of EVCS and effectiveness of the control algorithm are validated through the simulation and the experimental results.
