Fast Charging Stations Supported By Flywheel Energy Storage Systems

For an attractive means of transportation Plug-in electric vehicles (PEV) emerged in a strong political impetus creating environmental awareness. Consumer benefits from the DC rapid charging (DCFC) by lowering the waiting time and time required for charging. It supports distant EV travel and allows the electrification of high mileage fleets. Many EVs in FCS will create a noteworthy disturbance on gird in its basic form. It deducts the equivalent spinning reserve of the system and leads to frequency collapse. An ancillary energy storage system (ESS) to a common DC link will help to reduce this harsh issues. This ESS will help to create a power butter which supplies a portion of charging power. Flywheel energy storage system (ESS) is gathering interest because of its number of advantage offered over other storage solutions. Flywheel energy storage device can provide the power during the initial stage of charging of an EV battery. Adding to this an adaptive DC bus voltage control for grid converter is implemented to strengthen the system stability and efficiency.
