Electric Vehicles Aggregator Management in Active Distribution Networks

The burden of electric mobility will be mainly on the distribution system that, particularly during the peak hours, will be exposed to critical operation conditions by a high number of high density simultaneous loads. By adding control capabilities to charge and discharge of cars’ batteries, Vehicle-to-Grid technology can exalt the benefits from their whole energy storage capacity and Distributors can then be helped in the active management of the network by the services offered. For a full exploitation of Vehicle-toGrid potentialities, the role of the aggregator is essential to create value to customers by offering services to the distribution system operator. In the paper, a Particle Swarm Optimization is used to define the aggregator’s optimal control strategy to optimize the recharging patterns of a fleet of EVs taking into account financial contracts, driver’s behavior, energy prices, etc.
