Research on Plug-in Electric Vehicles Dispatch Strategy Considering Battery Life

The orderly charging and discharging management of plug-in electric vehicles (PEV) can enrich the control means of power system. However, frequent state transformation of charging and discharging may affect the battery life. This paper proposes two PEV dispatch methods taking battery life into consideration. The first is to cluster and classify PEVs based on their charging urgency, and arrange their charging and discharging behaviors accordingly. Under the premise of meeting the travel demand of each PEV user, the second method continuously charges/discharges the PEVs until the required power of PEV charging stations is satisfied. Finally, numerical studies demonstrate the effectiveness of the presented methods.
