Resumen:
This work addresses an energy management model for a charging station for electric vehicles (EVs), considering a residential microgrid (MG) with the ability to interconnect to a distribution network. The components of distributed energy resources (DERs) consist of photovoltaic solar generation (PVSG) and a battery energy storage system (BESS) with bi-directional energy flow capacity. The modeling of the profile and energy consumption associated with the EVs has been developed based on real data from a fleet of electric taxis. A novel model is presented which represents the EV battery charging system based on its State of Charge (SoC) and the variability in current and charging time. Additionally, profiles of electricity consumption of residential users in Quito-Ecuador are considered and modeled. Regarding the design of the PVSG system, records of meteorological stations have been taken into account and, through a statistical-probabilistic analysis, the typical radiation and temperature profiles in the city of Quito is determined. With this, through simulations, the energy produced by the PVSG system was established with a efficiently manage of the energy and store it in the BESS, allowing thus, nightly charging of EVs for different SoC scenarios. Modeling, analysis, and simulations were performed through the Quasi-Dynamic in PowerFactory DIgSilent. The results show how a EV charging station can be efficiently managed in the environment of a residential MG through PVSG and BESS systems.
