Enhanced Transmission and Distribution Network Coordination to Host More Electric Vehicles and PV

Distributed energy resources (DERs) installed at electric distribution networks create different opportunities and challenges for the system operator (DSO). By increasing penetration level of DERs, impacts these technologies are also sensed by transmission (TSO). The focus this paper is on investigating managing Electric Vehicle (EV) charging solar Photo-Voltaic (PV) generation considering TSO-DSO interaction constraints. These constraints include driving point impedance that reflects impact DER-rich upstream HV network voltage profile control through on-load tap changing (OLTC) transformer's operation. aim to optimally utilize existing assets flexibilities have more EVs PVs without violating both levels. proposed model could readily be used policymakers design implement proper time-of-use tariffs improved handling penetrations in emerging networks. method implemented IEEE 69-bus standard MV demonstrate applicability.
