Review of vehicle to grid integration to support power grid security

With the rapid growth of electric vehicles (EVs) and the widespread deployment of charging infrastructure, the analysis of vehicle to grid (V2G) integration on the security and stability of the power grid has become a hot issue of research and practice. In this paper, the impacts of V2G integration and corresponding charging facilities are comprehensively considered, with the consideration of frequency modulation, voltage regulation, power angle stability and harmonic filtering. The demands of power grid security are revealed considering frequency modulation, voltage regulation and reserve capacity. Moreover, this paper explores potential of V2G integration and several scenarios to support the secure operation of power grid including frequency modulation, voltage regulation, reserve capacity, and renewable energy accommodation. Furthermore, the current standards and demonstration application projects of V2G actively supporting power grid security are analyzed. Prospects for V2G integration are provided for a reliable and secure power gird.
