Abstract:

The e-mobility potential determination to support renewable energy grid integration in Menorca, and similar touristic islands, is the focus of this paper. The potential of e-mobility to participate in intermittency flattening ancillary services (AS) to support solar photo-voltaic (PV) grid integration is analysed in this paper. First, the capability of Plug-in Electric Vehicles (PEVs) to act as Energy Storage Systems (ESS) based on daily energy storage potential (ESP) with and without vehicle-to-grid (V2G) services is studied. Mobility behaviour and penetration levels of various categories of vehicles-cars, vans, trucks, buses and motorcycles in the island are modeled using traffic data from Menorca island. Next, ancillary service potential of 1000 PEVs to support solar PV grid integration is analysed. A crucial parameter of PEVs to offer uni-V2G services under aggregator to participate in hour-ahead AS market, termed achievable power capacity (APC), is explored. Results showed that, for bidirectional V2G services in summer, ESP can reach up to 100 MWh for minimum (P1) and 375 MWh for maximum (P6) penetration levels considered. The regulation potential for every 1000 private PEVs aggregated to a maximum of 4.6 MW and reserve potential to a maximum of 5.25 MW under coordinated charging. This reveals the great potential of PEVs in offering AS in small touristic islands. Adoption of e-mobility is a promising option in touristic islands to reduce the carbon footprints and to protect their biodiversity
