Samenvatting

A lab-based test setup was developed to simulate a novel droop rate controlled DC bus charging plaza installation in the Netherlands. The system consists of multiple bidirectional DC charging points, a PV array and a bidirectional grid connection. Currently the installed system employs linear droop control at the charge points and active grid connection. This lab setup allows for the testing of new control schemes, such as piecewise linear droop control, before implementing in the installed system. The simulations performed in this study investigate a variety of power flow scenarios and determine appropriate voltage and current setpoints and control mechanisms.
