Analysis of the Exploitation of EV Fast Charging to Prevent Extensive Grid Investments in Suburban Areas

Voltage control decreases the need for conventional grid reinforcement: We analyze the extent to which voltage control strategies decrease critical voltage levels compared to uncontrolled charging of EV in suburban low voltage grids. If in the underlying grid at the same time both active and reactive power control is applied for all sub-scenarios the volume and frequency of power limitation is reduced and in most cases a power limitation of 2 kW satisfies the voltage boundaries.
