Deployment of renewable energy sources (RES) and transportation electrification are the major efforts underway to reduce the carbon footprint globally. Grid integration of these two components is a mixed bag of challenges and opportunities. With the projected increases in electric vehicles and the fast-charging technology deployment. their grid integration poses challenges in terms of stability, and overall performance. Adding fast-charging EV loads overloads the distribution feeders and transformers locally. The increasing presence of these charging loads also modifies the daily load curve of the total system, resulting in voltage congestion. To address this concern, adding RES to enhance EV hosting capacity is a go-to solution. The main aim of adding the RES is to eliminate minimize feeder overloading and minimize distribution losses However, the RES and EVS with their power electronie interfaces inject harmonies into the utility grid. resulting in poor power quality. Thus, there is a need to assess the harmonic profile of the distribution system and propose suitable solutions to improve the power quality of the grid.
