The integration of flexible distributed energy resources in distribution grids, for instance EVs and battery storage, is often analyzed through optimal power flow approaches (OPF). A large variety of OPF-compatible unit models is observed. Furthermore, reactive power control models are often absent or limited in scope. This paper derives general unit models, composed out of two submodels: a ‘grid...
This paper quantifies the impact of single-phase on-board charging strategies for electric vehicles (EVs) in a case study of a heavily loaded unbalanced Flemish three-phase low-voltage residential grid. Voltage droop charging and EV-based peak shaving, which do not need communication with the distribution grid, are modeled and the results are compared. The grid voltages are analyzed according to the...
Uncoordinated charging of electric vehicles may cause significant voltage deviations in some residential distribution grids. Grid voltage stabilizing load models, such as developed for distributed energy resources, can be applied to electric vehicle chargers as well. A fleet of 10 electric vehicles is considered, modeled according to current Flemish mobility behavior. For this fleet, different voltage...
