Abstract
An experimental platform is developed with the aim of evaluating the performance of grid forming strategies in bidirectional electric vehicle (EV) chargers. The test bench is developed connecting a battery simulator to a grid simulator using a power converter that acts as an EV charger. This EV charger is composed of two stages: a DC/DC that increases the DC voltage of the battery, and a DC/AC that exchanges active and reactive power with the grid. The interface between the EV charger and the grid is done using an LCL filter, which is designed to meet the power quality requirements of the grid standards. The controller is a cRIO-9040, which integrates the control algorithms for both DC/DC and DC/AC stages, and a high acquisition task (10 kHz). The results obtained in the test bench are compared with the simulations carried out in Matlab/Simulink, showing the appropriateness of the experimental setup to validate control algorithms.
