Optimal V2X operation of EV fleets with PV-battery charging station for demand-side flexibility provision

Abstract

<p>The increasing number of electric vehicles expected on the road in the coming years poses new threats to the reliability of the power system. However, it can also play a key role as a source of demand-side flexibility to support the system in managing uncertainty resulting from the integration of renewable and distributed energy resources. In this paper, a novel operational tool for vehicle-to-everything operation of electric vehicle fleets with photovoltaics-battery charging station for demandside flexibility provision is proposed. The tool provides electric vehicle aggregators with a risk-aware flexibility quantification, robust market bids and real-time control decisions. The approach was tested on real demonstrators in Switzerland, highlighting the cost-benefits of demand-side flexibility provision.</p>
