Decarbonization Dispatching Strategy for Electric Vehicles Based on Life Cycle Analysis
Although electric vehicles (EVs) can help alleviate the energy crisis and environmental pollution, their uncoordinated charging schedules could bring significant negative impacts on the secure and economic operation of power and traffic systems. Given this background, a decarbonization dispatching strategy for EVs based on life cycle analysis is proposed. First, life cycle analysis theory is briefly described. A microscopic traffic flow model (MTFM) is next established as a link between the power system and traffic system concerned. Further, according to the difference between urgent and flexible charging characteristics, a corresponding dispatching strategy is formulated for EVs. For fast charging EV users, the charging station (CS) selection and navigation strategy is addressed. For EV users employing slow charging, a bi level optimal dispatching model considering decarbonization, distribution system security and battery loss is presented based on life cycle analysis. Finally, a coupled system including a 195 node traffic system and a 22 node distribution system is employed to demonstrate the effectiveness of the proposed model and method.
