| contents | The increasing penetration of electric vehicles (EVs) introduces significant flexibility potential to power systems. However, uncoordinated or synchronous charging can lead to overloading of distribution networks. Extending recent approaches that utilize generalized polymatroids, a family of polytopes, to represent the aggregate flexibility of EV populations, we show how to integrate network constraints into this representation to obtain network-constrained aggregate flexibility sets. Furthermore, we demonstrate how to optimize over these network-constrained aggregate flexibility sets, and propose a disaggregation procedure that maps an aggregate load profile to individual EV dispatch instructions, while respecting both device-level and network constraints. |
