Smart charging for an electric vehicle aggregator considering user tariff preference

Massive introduction of electric vehicles (EV) generates opportunities and challenges for society. In this way, a new entity of electricity markets which have to manage electric vehicles charging is needed, the aggregator. This paper proposes a smart charging for an EV aggregator which uses a user tariff preference. Users will select between three different tariffs and the aggregator will modulate charging power rate in order to optimize charging costs. The aggregator will also take into account a charging pattern given by Distribution System Operator (DSO) and Transmission System Operator (TSO), and the energy desired by each user.
