However, due to limitations in the availability of components and the need for greater flexibility in testing scenarios, the use of component emulators becomes essential. Among various approaches, the emulation of power system components using Power Hardware-in-the-Loop (PHIL) is widely adopted. Despite their advantages, PHIL setups are inherently complex, and the non-ideal behavior of the looped components necessitates the implementation of dedicated interface approaches and compensation methods. This work highlights the challenges associated with the accuracy of PHIL setups for the emulation of High-Power-Charging systems for Electric Vehicles. Particularly, it addresses the issue of maintaining correct active and reactive power flow between the setpoints provided by the real-time simulation and the output of the power interface at a given Point of Common Coupling. A novel and practical interface compensation method is proposed and successfully implemented to improve the overall accuracy and performance of the setup under various operational conditions. Results demonstrate that the suggested method significantly improves accuracy by reducing steady-state error of the power flow from up to 7.31% to less than 0.01% during low-dynamic charging operation.enPower hardware-in-the-loopElectric VehiclesHigh-Power-Charging620ConferencePaper
