The Energy Ring to supply the Expoelectric'18 show with Renewable Energy Sources and Electric Vehicles

The Expoelectric fair takes place every year in Barcelona (Spain) and is devoted to Renewable energy and Electric Mobility. Street trade shows and fairs usually use Diesel generators to provide energy to fair booths because the street infrastructure is not designed to supply these events. In the case of Expoelectric and its objectives, the organization has proposed to supply the fair booths with on-site renewable energy and the use of exposed electrical vehicles to provide storage, which makes excellent sense in this kind of events. This paper aims to show this experience and detail the system developed for this objective. The result is the development of a power electronics-based system able to generate the grid where other resources and storage elements are connected. This paper details the system but also the control and operation algorithms to operate the microgrid without any type of communication between all the elements connected to them. During the two days of the fair, the Energy Ring microgrid delivered energy to the booths, assuring the supply and power quality needed for all the equipment connected (lighting, freezers, EV chargers, and computers).
