Optimized and Coordinated Charging Methods for Electric Vehicles Cost

Increasing awareness and worry about ecological and environmental problems and the shortage of oil resources are strong incentives to develop more efficient vehicles, with lower fuel consumption. Electric vehicles (EVs) usage is showing a rise in response to the proper time and conditions. Rapid growth of electrical vehicles accessing the electric grid, demands meticulously designed charging scheduling algorithms in smart grid applications [3]. Several influencing factors affect the profiles of the EV charging load, such as charging start time, daily driving distance, capacity of their battery and environmental factors. Smart charging/discharging strategies of EVs can decrease daily cost of electricity for EV owners, assist in peak load shaving in the power grid, and improve reliability of power system. This paper focuses on optimized and coordinated charging of EVs and its effects on the load profile of the system.
