MENDOZA, Cristian C.; QUINTERO, Adriana M.; SANTAMARIA, Francisco  and  ALARCON, Alexander. Coordinated recharge of electric vehicles in real time. Dyna rev.fac.nac.minas [online]. 2016, vol.83, n.197, pp.222-231. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v83n197.55342.

The electric vehicle is a transportation technology that requires a management system for the electric networks of the future in order to avoid overloads and adverse effects on voltage level and power quality. This article presents a management algorithm to adjust the operation and recharge conditions of electric vehicles in real time, optimizing the use of network capacity and improving the voltage profile through the coordination of recharges depending on loss sensitivity; an approach to identify nodes where power losses can decrease or increase under a specific load condition. The results obtained by applying the strategy are presented through a random consumption model of vehicles based on existing mobility patterns using a distribution circuit of 628 nodes. This allows the identification of electric vehicle penetration after which it becomes necessary to implement the proposed management scheme.

Keywords : Electric vehicle; management algorithm,; recharge coordination; selection of maximum sensitivities; sensitivity ranges; voltage level; power losses; maximum capacity.
