MULTIPLE OPERATING MODE-BASED ELECTRIC VEHICLE CHARGING STATION

Abstract

This work aspires to enhance the continuity of the feeding charging facility of electric vehicles (EVs) by incessant charging stations (CS) for several modes, grid mode, diesel generator (DG) set mode, or off-grid mode. This is accomplished by binding the three modes, grid-connected, Solar PV, battery energy storage system (BESS), and DG set to charging an EV. Originally the design of the CS used the SPV array to let BESS utilized to charge the EV battery. Secondly, employing the grid to charge the storage system of the EV, and if there is unavailable power, the DG set, will provide energy to the CS.The supply of CS from the DG set, or the grid option occurs when it’s zero sunlight extracted by SPV and the BESS is exhausted. Even so, at 80-85% the load will be maintained in order to obtain ultimate the efficiency of the fuel in each of the load statuses while the Diesel generator produced energy. In a set of BESS, the performed frequency and voltage is controlled by CS. On the other hand, it emphasizes that the extracted energy either from the DG set or grid is at unity power factor (UPF) even though at non linearity loads. The achieving of concurrence is done at the point of common coupling voltage, to the DG or grid to realize constant charging. The performance of transferred power of the active or reactive vehicle to home, vehicle to grid (V2G), and vehicle to vehicle is accomplished to raise CS practicability efficiency. In the based system it used a PI controller, and due to that the steady state is low and the harmonic as well are high. In the proposed design the replacement of the PI controller with the ANFIS controller will be the solution for these problems.
