Distributed Energy Resources Based EV Charging Station with Seamless Connection to Grid

The work implements the common DC bus electric vehicles (EVs) charging infrastructure based on hybrid renewable energy sources such as solar photovoltaic (PV) and fuel cell. The requisite to incorporate distributed energy resources (DERs) is attributed to the escalating concern for decarbonisation with improved power quality requirements. Furthermore, the bidirectional flow of power enables the transition between modes of grid presence/absence. The utilization of an adaptive comb filter is achieved for satisfactory operation during mode with synchronization ability along with power transfer proficiency and improved power quality requirements. The utilization of common DC bus charging mechanism for EVs, facilitates fast charging capability at higher voltage levels. Thus, for validation and corroboration of the system behavior, its performance is authenticated during weak grid conditions in conjunction with grid connected/islanded modes of operation.
