Metodología para la ubicación óptima de estaciones de carga de vehículos eléctricos en sistemas de distribución de energía eléctrica considerando el comportamiento del usuario y la red eléctrica

Abstract

This work proposes a methodology to allocate electric vehicle (EV) ulta-fast charging stations (UFCS). The methodology considers three entities: EV firms, EV users, and the electric system operator. A flow capturing location model is used to consider the interactions between traffic network and electrical network. The entity involved in each network has an independent objective. Thus, the interplay between the electric system operator and the EV firm interested in allocating UFCS are modeled using a bilevel optimization problem. The upper level considers the flow capture location model leader by the EV firm while in the lower lever the objective belongs to an economic dispatch follow by the system operator. Electric load uncertainty is considered in the lower level, so the bilevel optimization problem is solved for different scenarios. The charging station locations given by the bilevel problem allows to analyze the impact of them in the electrical grid. This analysis can be performed by cascading failure. The methodology is validated in the IEEE 30 BUS system.
