Assessment of Ancillary Services Provided by a Bidirectional Capacitorless Charger for Electric Vehicles

摘要

This paper aims to assess the ability of bidirectional chargers for Electric Vehicles to provide ancillary services for Smart Grids, such as frequency regulation and active filtering. The charger is composed of a conventional AC/DC converter and a three-phase Dual Active Bridge DC/DC converter with an adaptive control that takes into account the change in the battery voltage and the charging/discharging power. These ancillary services are tested using Simulink/Simscape and verified in a real-time environment via Hypersim.
