New Control Paradigm and Dynamic Pricing Scheme for Low Voltage Direct Current Networks

The massive presence of DC Distributed Energy Resources (DER), the fast growing Electric Vehicle (EV) infrastructure and the dominance of DC based consumers gave significant pace for development of Low Voltage Direct Current (LVDC) grids. This paper presents a new concept, control paradigm and Dynamic Pricing Scheme for Low Voltage Direct Current Networks. The concept and market scheme rely on a leading signal based on the network parameters at the point of common coupling (PCC) which makes it simple, safe, easy to implement and reliable. The main methodological and economic concepts are presented after which a Power Hardware in the Loop (PHiL) laboratory demonstration experiment with flexible load control is performed and presented. Based on the results obtained some valuable conclusions are made.
