Carbon Reduction Assessment of Electric Vehicle Aggregation Participating in Distribution Network Dispatching Based on V2G Technology

Abstract

With the increasing popularity of electric vehicles (EVs), the aggregated operation of V2G electric vehicles can be used as a flexible dispatchable resource to participate in the dispatching of the distribution network, which can improve the level of renewable energy consumption. To realize the aggregation of V2G electric vehicles to participate in distribution network scheduling, taking into account the needs of distribution network and electric vehicle users, considering the constraints of safe operation of distribution network and electric vehicle, a two-layer optimal scheduling model for EVs and distribution network is established, achieving the goals of maximum renewable energy utilization in the distribution grid and minimum costs to EV users. Then, the second order cone planning is used to convex and linearize the power flow constraints of the distribution network, and the ADMM algorithm is developed to solve the two-layer model. Finally, based on the improved IEEE33 node study case, the carbon emission reduction benefits of V2G electric vehicles participating in distribution network dispatching in different modes are compared.
