Simultaneous, Coordinated and Centralized Control of Fast Charging Stations and Advanced Microgrids

The insertion of fast charging stations (FCSs) and distributed energy resources (DERs) aggravates technical issues in the electrical power system, such as variations in the point of common coupling (PCC) voltage profile and overload on feeders. Ancillary services provided by these elements help to reduce these issues and microgrid (μG) control algorithms coordinate these ancillary services. However, microgrid control studies focus on solutions that do not simultaneously coordinate FCSs and DERs, nor the coordination of advanced microgrids and FCSs. This paper proposes a coordinated and simultaneous control of FCSs and advanced microgrids. The results show that the proposed method performs the ancillary services of valley filling and peak shaving in a minigrid (MG) (i.e., a set of advanced microgrids, FCSs and others). This method allows the voltage profile to be maintained at appropriate levels, ensuring the commitment to vehicle recharging and the independence of the advanced microgrid.
