Coordinated Operation of Electrified Transportation Networks Considering Road Capacity Drop

This paper proposes an optimal transportation-power flow (OTPF) model to manage electrified transportation networks (ETNs) with dynamic wireless charging (DWC) facilities. The transportation network (TN) model, considering the road capacity drop, is adopted for traffic flow assignment. The Distflow model is used to calculate the power flow in the power distribution network (PDN). Energy storage systems (ESSs) and flexible loads (FLs) are integrated into the coordinated operation of ETNs to enhance the economy and security of the system. To address fluctuations and variations in renewable energy generation, model predictive control (MPC) is adopted. The proposed MPC-based OTPF model is formulated as a nonlinear and non-convex problem. To obtain the global optimal solution, it is further transformed into a mixed-integer second-order cone programming (MISOCP) problem by using second-order cone (SOC) relaxation, piecewise linearization, and the Big-M method. Case studies verify the significant influence of road capacity drop on the operation of ETNs.
