Electric vehicle charging stations drastically affect the power quality of the distribution network. To improve power quality with greater charging station involvement and optimal use of space availability in the charging station infrastructure, it is necessary to develop new charging algorithms to optimize the use of electric resources.

Abstract

Electric vehicle charging stations drastically affect the power quality of the distribution network. To improve power quality with greater charging station involvement and optimal use of space availability in the charging station infrastructure, it is necessary to develop new charging algorithms to optimize the use of electric resources. Coordinated charging is one of the key solutions to reduce the negative impacts of electric vehicle charging stations, which makes the charging duration similar to the connection duration. In this way, it is possible to spread the energy avoiding the peak of absorption. In contrast, the nominal power of charging is lower, with which the power quality in the network can be maintained. In this paper, an analysis is presented on distribution networks of the use of uncoordinated recharging and coordinated recharging, showing how the latter type of recharging makes it possible to significantly improve the impact of recharging on the power grid. The network considered is a medium voltage IEEE 69 bus test network.
