Abstract: In this paper, a multi-mode optimization technique for Electric Vehicle (EV) unidirectional charging station is presented. The objective of the proposed system is to reduce the cost of EV charging in an open electricity market. Moreover, the proposed algorithm can be integrated with renewable resources such as photovoltaics (PV), and wind turbines among others. The optimization procedure has three modes of operation to suit customer needs under different circumstances. The three suggested modes of operation are normal mode, eco mode, and boost mode. The aforementioned technique aims to reduce the cost of EV charging by finding the optimal schedule for charging in the available time horizon in each mode. In addition, the optimization algorithm varies the charging rate in order to meet the desired target for some special cases. The optimization technique is based on the Priority List which makes it simple to be implemented online. A case study is presented to illustrate the benefits of using the suggested optimization procedure. The results show the financial feasibility of the proposed procedure.
