PROJECT TITLE :

Optimal Charging/Discharging Control for Electric Vehicles Considering Power System Constraints and Operation Costs

ABSTRACT:

With the popularization of electrical vehicles (EVs), the influence on power systems is receiving increasing attention. Consistent with statistics, EVs are during a parking state for additional than ninetypercent of the time, therefore, the electric energy of the EVs accumulated by aggregators can be used to support the operation of power systems. This paper takes reducing operation prices as the objective perform and considers the constraints of EVs and power systems to determine the optimal charging/discharging management of electric vehicles, which meet the operational safety of power systems and convenient driving. The influence on operation costs, peak load, and loss for the proposed charging/discharging 2-manner management, charging-only control, and free charging modes of EVs are compared. The influence of battery charging and discharging efficiency on these results is additionally discussed in this paper.
